How Often Do You Calibrate Your Measuring Devices?
Have you tried opening the same compass app from the very same phone models only to see widely different results like this? (It's hard to take a photo of the two phones perfectly on top of each other while showing both screens; we tried that anyway, and they still gave different angles relative to Magnetic North.) Unless you’re relying on those compass apps to perform delicate activities (such as tactical defence operations), the difference does not seem to matter much. Nevertheless, it illustrates a point. No two identical measuring devices will yield the “perfectly same exact” measurement all the time, but that shouldn’t stop us from using them. (We know that those iPhones aren’t standalone compasses, but you get the point.) We just have to trust they are giving us as accurate a measurement as possible. Here goes the inevitable topic of calibration, and you probably know that it’s not a matter of “if”, but a matter of “when”. More often than not, your measuring devices – be it gauges, meters, test kits or instruments of similar function – have one job: To give you accurate readings of whatever unit it’s supposed to measure. The problem is that there are factors that could affect their accuracy, and you don’t want to risk that. Why calibrate measuring devices? The short answer: Because you want them to give you accurate readings all the time. The long answer: Because prolonged inaccurate readings may have serious consequences Because you may be required by law (specifically, trade measurement laws) to keep your products true to their published measure. For example, when you manufacture and retail a variety of products (eg. packaged/processed food, raw food, petrol etc)* Because even minor out-of-tolerance outputs can have major negative effects when left unnoticed and not corrected immediately Because your customers don’t want to feel like they’re being ripped off In more practical terms, you want to have your measuring devices calibrated: To account for wear and tear of its mechanical and electronic components To ensure its accuracy, and therefore, reliability To ensure its reading doesn’t deviate too much from standard tolerances To ensure its reading is consistent with other measuring devices To keep it from having performance discrepancies Put simply, it’s just not possible to keep your gauges and meters performing at 100% of its designed accuracy and efficiency forever, as there are several external factors that could affect its accuracy. When to consider calibration As a minimum, Go Calibration recommends calibrating your instruments at least once a year “to ensure accuracy and provide quantitative data to ensure you can provide quality assurance for your customers.” (If you want an exhaustive list of calibration schedules for various equipment, here’s the National Association of Testing Authorities (NATA) Calibration reference equipment table as of September 2020.) Furthermore, here are instances when it’s a good idea (and even advisable) to have your measuring device checked for accuracy earlier than your scheduled annual check: When it is recommended by the manufacturer: There's a good chance that they have indicated in the owner’s manual their recommended calibration intervals, which could be more than once a year depending on various conditions. Use that schedule as your first reference when deciding whether you should have the instrument checked more often. Before you go on planned maintenance downtime: You’ll be shutting down operations to do routine checks and perhaps even inventory management. You’re probably even scheduled to replace components, parts and consumables (eg. lubricants) for preventative maintenance. You might as well use this time to have your measuring devices checked, so that you are confident that everything is in tip-top condition when you put them back together. Before you use them in a critical measuring project: This is especially important if you plan to make decisions based on the instrument’s readings. You want to be confident with its measurement results, especially if it will influence strategic action plans. For example, when it’s time to get checked for certifications. Before you undergo mandatory audits or inspections: Some industry regulators and federal authorities, such as the National Measurement Institute, subject businesses to audits and inspections in compliance with trade measurement laws. After a potentially damaging incident: While many measuring devices come in heavy-duty casing and built with internal overload protection mechanisms, there are occasions when its measuring integrity may have been compromised, such as (1) after being subject to mechanical and electrical shocks or (2) after taking physical damage, such as from an accidental drop. After being exposed to extreme humidity and temperature: Yes, these environmental factors can affect the accuracy of your gauges, even when they are sealed and designed for outdoor use. There are, however, some instruments that are specially designed to take much more humidity and temperature levels and fluctuations than their ordinary counterparts. As the instrument ages: The longer the instrument is in service, the more often you may need to have it calibrated, to account for wear and tear, until they are due for complete replacement. Put simply, as this US Navy video explains: “Like components, test equipment itself decays” and “without calibration, our costs [can] go up and our tactical efficiency goes down." Measuring devices we can help you calibrate Unless you’re a certified metrologist with the proper equipment and facilities, you are usually best to leave calibration to the pros. We can help you keep these instruments accurate: Backflow Test Kit Bore Gauge Centrifuge (RPM) Conductivity Meter Depth Gauge Dial Gauge (Mechanical/Digital) External Micrometers Height Gauge Metal Detector Micrometers pH Meters Pressure Gauge Pressure Transducer Tachometer Temperature Enclosure Thermometer Tyre Inflation Gauge Vacuum Gauge Vernier Calliper In a nutshell We hope this article served as a quick but practical reminder that: There’s no one-size-fits-all schedule to calibrate your measuring devices. A wise way to comply with applicable trade measurement laws is to keep your measuring devices calibrated. Wear and tear, extreme ambient factors and mishandling can affect your measuring devices' accuracy. As a minimum, have your measuring devices calibrated once a year. If in doubt, don’t wait and just have them checked. You can’t DIY the calibration, so leave it to the pros. We can help you calibrate your gauges - let's talk via chat or email. AIMS’ Note on Buying Industrial Supplies Breadth and depth of brands and categories: Go with a supplier that offers a wide range of reputable brands across multiple categories and sub-categories. Bulk purchase discounts: For large orders, check if you can take advantage of volume leverage. Some suppliers offer business accounts* that give you access to special pricing (volume discounts), preferential support and even credit eligibility (subject to supplier approval, terms and conditions). Product and service information: Evaluate the completeness and usefulness of data in their online product listings. Prudent suppliers will include as much useful information as possible to help you assess and compare products. In terms of service info, the supplier’s FAQs (if any) will give you a good idea of their standard policies*, processes and commitments. Promotions: Check for ongoing promotional campaigns so you can get the best prices. Many suppliers run regular discount-based promos. Some can point you to government-hosted rebate programmes like the SafeWork NSW $1000 Small Business Rebate. Safety compliance: Make sure the product in question meets Australian safety standards and regulations, especially if there are relevant compliance requirements or work health and safety (WHS) laws that apply to your business or state. Look for relevant certifications and markings where necessary. Supplier reliability: Choose reputable suppliers with a proven track record of delivering quality products and reliable customer service. Warranty and support: Check warranty terms and after-sales support* options, as this can be crucial in case of product defects or performance issues. Lead time and availability: Confirm product availability and estimated delivery times to avoid delays in your projects. Returns: Familiarise yourself with the suppliers returns and exchange policy in case you receive incorrect or damaged items. Delivery: Clarify delivery terms, including estimated delivery times, shipping costs and who handles insurance during transit (where applicable). *Need help with a purchase decision?

People Also Ask — Calibration Intervals for Measuring Tools Q: How often should I calibrate vernier calipers and micrometers? Calibration interval depends on usage intensity, environment, and the accuracy requirements of the application. As a general guideline, vernier calipers and micrometers used in production inspection should be calibrated every 6–12 months. Instruments used in critical quality control, aerospace, or medical device manufacturing may require 3–6 month intervals or more frequent checks. Less-used instruments in benign environments may be calibrated annually. The calibration interval should be documented in your quality management system and reviewed if instruments are frequently found out of tolerance during scheduled calibration. Q: What is the difference between calibration and verification? Calibration involves comparing an instrument against a traceable reference standard and adjusting or documenting the deviation to a known accuracy. Verification is a check to confirm the instrument is still within acceptable tolerance — typically a simpler check using a reference artefact (e.g., slip gauges for calipers) without formal adjustment. In ISO 9001 and AS/NZS ISO 9001-certified quality systems, calibration records must be traceable to NIST, NMI (National Measurement Institute of Australia), or another national measurement standard, and calibration intervals must be justified and maintained. Q: What Australian standard governs measurement equipment calibration? AS ISO 10012 (Measurement management systems — Requirements for measurement processes and measuring equipment) provides the framework for managing measurement uncertainty and calibration in a quality management context. For accredited calibration laboratories in Australia, NATA (National Association of Testing Authorities) accreditation under ISO/IEC 17025 is the benchmark. For in-house calibration in manufacturing and maintenance environments, AS 9100 (aerospace), AS ISO 13485 (medical devices), and ISO 9001 each have specific requirements for measuring equipment traceability and calibration records. Q: Can I perform in-house calibration or do I need an external laboratory? In-house calibration is permitted under most quality standards provided your reference standards are themselves calibrated by a NATA-accredited laboratory or NMI, your in-house calibration procedures are documented, and your calibration records are maintained. The practical constraint is that in-house calibration requires certified reference artefacts (gauge blocks, reference standards) with current calibration certificates. For critical measurements or regulated industries, external NATA-accredited calibration is often the safest path to ensure traceability and regulatory compliance. Q: What does 'out of tolerance' mean for a measuring instrument and what should I do? An instrument found out of tolerance during calibration is measuring outside its specified accuracy band — for example, a caliper rated ±0.02mm is consistently reading 0.05mm high. Action required: (1) quarantine the instrument immediately — mark it with a 'Do Not Use — Out of Calibration' tag; (2) assess the impact — any measurements taken since the last known good calibration may be suspect and products may need re-inspection; (3) investigate the cause — physical damage, wear, contamination, or drop incidents; (4) repair or retire the instrument; (5) document the non-conformance in your calibration management system for audit purposes.

Quick Guide to Anti-Slip Safety Compliance
In this article, we discuss: Are anti-slip solutions mandated by law? Specific standards for different flooring surfaces Common slip hazards Common trip hazards Which floor types (surfaces) need anti-slip solutions Where to use anti-slip products More anti-slip FAQs Are anti-slip solutions mandated by law? When it comes to slip resistance compliance, always err on the side of caution. If these work health and safety (WHS) statistics fail to convince you to install anti-slip solutions where your staff and customers walk, perhaps your legal duties will. Yes, as a business owner, you have a general duty of care. Put simply, you have WHS responsibilities. As we’ve emphasized in our slip resistance compliance guide: Slipping, tripping and falling are risks that can be associated with steps and stairs, and can lead to serious injuries. Under the WHS Act, the employer has a ‘duty of care’ to provide and maintain a safe and healthy workplace – all potential hazards must be identified, the associated risks assessed and then controls introduced to eliminate or reduce those risks as far as practicable. (Make sure to get your free copy of the guide here.) Your responsibility extends to making sure your customers, visitors, and any contractors are safe at your business premises. It is prescribed by Australian Standard AS1428.1 and a mandatory compliance requirement under the Building Code of Australia. Disclaimer: AIMS is not a WHS law expert, therefore the information provided here should be treated as general in nature and not be treated as specific, legal or professional advice. Our article about WHS laws only aims to compile resources that may be helpful to your business. Official sources of information are cited. Specific standards for different flooring surfaces Standards Australia has a compilation of the prescribed minimum slip resistance requirements for different flooring surfaces. Here are the links for your convenience: Designation Title AS 4586:2013 Amd 1:2017 Slip resistance classification of new pedestrian surface materials AS 4586-2013 Slip resistance classification of new pedestrian surface materials AS 4663-2013 Slip resistance measurement of existing pedestrian surfaces AS/NZS 3661.2:1994 Slip resistance of pedestrian surfaces, Part 2: Guide to the reduction of slip hazards AS/NZS 3661.2-1994 Slip resistance of pedestrian surfaces - Guide to the reduction of slip hazards AS/NZS 4586:2004 AMDT 1 Slip resistance classification of new pedestrian surface materials AS/NZS 4586-2004 AMDT 1 Slip resistance classification of new pedestrian surface materials HB 197:1999 An introductory guide to the slip resistance of pedestrian surface materials HB 197-1999 An introductory guide to the slip resistance of pedestrian surface materials SA HB 198:2014 Guide to the specification and testing of slip resistance of pedestrian surfaces Common slip and trip hazards You can refer to this comprehensive fact sheet from Safe Work Australia (SWA) when trying to identify what may possibly cause a slip or trip accident. For your convenience, we’ve simplified SWA’s list below. Common slip hazards: Spills of liquid or solid material Wet cleaning methods Wind-driven rain or snow through doorways Sudden change in floor surface (eg. joins between carpet and polished timber) Change from a wet to a dry surface Dusty and sandy surfaces Ramp incline Bumpy/Loose flooring Poor lighting Use of unsuitable footwear Common trip hazards: Ridges in floors or carpets Worn floor coverings Broken tiles Cracks and potholes in floors Changes in floor level Thresholds and doorstops Floor sockets and phone jacks Cables from power extension units Loads that obstruct vision Obstacles in traffic areas For more information, be sure to read our article about how you can prevent slips, trips and falls in the workplace. Which floor types (surfaces) need anti-slip solutions SWA’s fact sheet has a quick guide to help you figure out which kinds of surfaces get slippery in what situation: Floor Type Characteristics Concrete Rounded aggregate can be slippery when concrete wears. Interior surface is often sealed to prevent dusting and absorption of liquids - this can increase slipperiness. Terrazzo Gives good appearance and wears well but can be slippery when wet, when excess polish is used or when dusty. Quarry tiles, ceramic tiles Low water absorption and good resistance to chemicals. Slippery in wet conditions if smooth, but can be moulded with aggregate or profiles to improve slip resistance - special cleaning equipment may then be required. Glazed ceramic tiles Slippery when wet, particularly with soapy water. Some slip resistance treatments available, but preferable not to install these tiles on floors. Vinyl tiles and sheet Easy to clean. Use sheet form where frequent washing is required to avoid water getting under tiles. Slippery when wet, particularly if polished, however slip resistant vinyls are available. These have aggregates moulded in. Thicker and softer vinyls are more slip resistant than hard ones. Cork Must be sealed to prevent absorption of oil and water, but may then be slippery when wet. Steel plate Tends to be slippery when wet or oily, particularly when worn. Rubber Less effective in wet conditions. Must be fixed down well at the edges and joints or will cause a trip hazard. Plastic matting Interlocking PVC extrusions give good drainage and slip resistance. Hose down or steam clean. Carpet Carpet has a shorter life than hard floor surfaces, but it can be a cost-effective solution. Installations should be wall to wall, to avoid the hazard of a trip on edges. When used in small local areas, such as at entrances, it should be installed in a recess in the floor. Alternatively, it should be rubber-backed and with hardwearing tapered edges. Trolleys can be harder to push on carpet, but if larger wheels are fitted and the carpet does not have a deep pile, this is not a serious problem. Fiberglass gratings This product can have grit particles moulded into upper surface to provide very good slip resistance. Fluids are quickly drained away. Where to use anti-slip products Standard anti-slip products are installed in relatively familiar pedestrian locations: Ladders rungs: The mostly smooth and often small foot surface area on ladder rungs present an extremely high-risk hazard that needs to be made safe by being covered with anti-slip material as specified in AS1657. Here are more reasons why ladder rung covers are essential for safety. Landings, platforms, ramps and walkways: Even flat surfaces can become slippery when left oily, overly polished or wet. That's where you need safeplates to ensure firm footing. Steps, stairs and stairwells: Slips, trips and falls on stairways are a more common occurrence in industrial and commercial environments than they should be, sharing about the same frequency of incidents being reported. Consider installing stair nosings in those places. There are even commercial grade ones for surfaces such as ceramic, concrete and masonry. Conveyor channel cleats: Slip-proof these surfaces with cleats that provide firm footing on most types of grating mesh conveyor ramps, platforms or walkways (even those with a sharp incline). You’ve probably even seen anti-slip products during your daily routine and haven't really noticed them placed on: Transport and logistics vehicles Trains and station platforms Emergency service vehicles Construction and mining machinery Food production equipment Weighbridges Skateboards They’re even on infrastructure projects, such as: Bridges Dams Tunnels Anti-slip products are also widely used in various areas in civil aviation and the agriculture sector. We’re guessing there’s a big chance you’ll need an anti-slip solution for your business. In the meantime, here are some easy things that you can do quickly to prevent slips: Use anti-slip tapes Apply anti-slip coatings More anti-slip FAQs The safe surfaces industry is one of the most important sectors in the safety market for protecting workers, visitors, contractors and all pedestrians from incident and injury due to a slip, trip, stumble, tumble or a fall. Anti-slip products come in a wide variety of shapes, sizes, colours, coarseness grades and are required to achieve a multitude of different results, such as: Safety Compliance requirements Visibility Aesthetic Covering of an aging or worn surface Do you need different kinds of anti-slip for indoor and outdoor use? Primarily, you will consider the level of safety that the anti-slip product can provide. There are instances where indoors is harsher and has more slip hazards, especially in workplaces where floors often get liquid spills. In this case, the level of coarseness will make all the difference. Which level of coarseness (grade) is right for my intended use? Consider the types of pedestrians that need to be kept safe from a possible slip, stumble, trip, tumble, falter or fall. Grade Generally used in Barefoot – 80 ISO (86) Areas where people may walk around in bare feet or in open-toed footwear, and there is no excess buildup of dirt, dust or debris, such as in child care centres, playground areas, picnic grounds and community pools Fine – 46 ISO (86) Industrial – 24 ISO (86) Commercial or light industrial applications where an increased level of safety is required, such as at educational institutions, walkways and ramps for people with a disability, some residential applications and public transport infrastructure Heavy Duty – 20 ISO (86) Industrial applications where workers and visitors need a superior level of safety when traversing all types of pedestrian access areas, due to the possibility of an excess of dirt, dust, debris or spillage of product in trafficked areas around the workplace Offshore – 16 ISO (86) Applications where there is a high accumulation of, or the presence of carbon greases, heavy oils, or increased spillages on a stairway, walkway, platform or landing need the highest level of safety surface When installed to manufacturer guidance, standard metal-backed anti-slip products would generally have beads of silicone adhesive applied to bond the metal to the substrate. That, in addition to a layer of laminated material and resin coating, makes the product safe from potential electrical/static conduction, according to Advance Antislip Solutions. What are your anti-slip products made of? According to Advance Anti-Slip Surfaces, their main range of anti-slip, metal-backed products are made from high quality, BlueScope sheet products such as Colorbond®, Galvabond®, as well as 5052 aluminium and 316 stainless steel. They also offer anti-slip tapes. Do they corrode and rust? The sealed surface is unlikely to corrode or rust. It’s because the foundation elements are machine pressed, sheer cut from sheet steel, and the edges are coated and sealed to protect the metal. What about anti-slip coatings? Applied anti-slip floor coating and slip-resistant coating products have their place in the safe surfaces industry, especially where there are extremely large square metreage areas that need to be made safe for pedestrians. They are initially very effective at preventing slips and falls; however (over time and with lots of machine cleaning), they will wear away and need resurfacing at regular intervals. They also need a lot of time to dry before pedestrians can access the area. What kinds of liquid can your anti-slip products “resist”? They are resistant to most solvents, petroleum products and acid solutions. High concentrations of chemical, alkali, acid, solvent or other liquid contaminant (that may be harmful to humans even when wearing safety boots with slip-resistant soles) could have an effect on the product’s hardened resin coating. Although so far, we haven’t come across an instance where the products have succumbed to such a liquid contaminant attack. How do I keep the anti-slip products clean? You can use a firm bristle brush/broom and mops to clean them. You can even spray them with pressurized water, too (if that’s part of your housekeeping SOP). Most readily available surfactant-based detergents can clean the non-slip surface well enough, and most diluted cleaning chemicals clean the anti-slip surface without affecting its integrity. Avoid acid-based cleaning chemicals with high concentrations of acidic components. What are the available colours? You can choose from our standard colour range chart. The most popular is Safety Yellow. We also offer “higher visibility” photo-luminescent (glow in the dark) Safety Yellow, Nano Green and Safety Red. Can I relocate (reuse) the products to a different location/surface later on? Relocating or repositioning a previously installed metal-backed anti-slip product is possible if it is removed from its existing location without sustaining any damage. If you intend to reposition them on a similar surface, there should be no potential issues, although a quick check with us to confirm the details might be wise.

Anti-slip products reduce the risk of slips, trips, and falls on surfaces that become hazardous when wet, oily, or worn. They include anti-slip tape, grit coatings, stair nosings, anti-fatigue matting, and floor markers. The right solution depends on the surface type, traffic level, and the likely contaminant — water, oil, dust, or chemical. Q: What is the difference between anti-slip tape and anti-slip coating? Anti-slip tape is a peel-and-stick abrasive product — fast to apply and easy to replace, ideal for targeted high-risk zones like stair edges and ramp entries. Anti-slip coating is a paint-based product that bonds to the floor surface and covers larger areas uniformly. Coating is more permanent; tape is better suited to localised treatment or temporary installations. Q: Where should anti-slip tape be installed? Anti-slip tape is most critical on stair nosings, ramp entry and exit zones, loading dock edges, machinery access platforms, and any walkway where surfaces become slippery under normal operating conditions. Pay particular attention to transition zones between outdoor and indoor areas, where workers track in moisture on their footwear. Q: How long does anti-slip tape last in an industrial environment? Lifespan depends on traffic volume, surface preparation, and exposure. In low-traffic areas with correct surface prep (clean, dry, oil-free), quality anti-slip tape can last 3–5 years. In heavy industrial areas, expect 12–24 months before replacement is warranted. Worn tape is as hazardous as no tape — inspect regularly and replace on any sign of lifting or wear-through. Q: Does anti-slip matting replace fixed floor treatments? No — they serve different roles. Anti-slip matting is best at entry points, workstations, and fatigue reduction zones. Fixed treatments (tape, coating, stair nosings) are required in thoroughfares, stairways, and ramps where matting would itself create a trip hazard. A layered approach combining matting at stations with fixed treatment in walkways gives the best overall outcome.

Why Thermal Protective Work Gloves Are Crucial For Safe Handling
(Taken from this post by Beaver Brands. Republished with permission. Edited for point of view and relevance.) When working in cold environments, manual tasks can lower body and hand temperature making handling and gripping objects more difficult. This can increase the risk of hand and arm grip force reduction, leading to a decrease in blood flow to muscles, thus increasing fatigue and the chance of injury. Within the workplace, hands are most likely to be affected by cold temperatures. When selecting gloves, consideration must be given to the most appropriate product for the temperature, or the tasks being performed within the environment. Factors such as insulation, fit, flexibility, dexterity, job role and hazard need to be considered. Keeping warm is a basic need that all of us share. For those who work in cold temperatures and environments, the need to keep their hands warm and protected is of major importance. Choosing quality hand protection will aid in avoiding potentially serious health risks like frostbite, fatigue, and accidents on the job. People who work within cold handling and cold environments can be both indoors and outdoors and include industries and occupations such as refrigeration, cold storage, warehousing, logistics, transportation, construction workers, maintenance, mechanical, machine operators, baggage handlers, airplane mechanics, and emergency services personnel - who are often exposed to cold stress. Lighting can also be compromised in both indoor and outdoor cold temperatures, and some gloves even provide hi-visibility (hi vis) variants to aid in further protection within low light environments. Ninja Celsius Ice As their name suggests, this high performance cold-resistant glove not only provides thermal protection, but also liquid resistance and superior grip and dexterity for cold applications. Ninja Celsius Ice safety features: Advanced, proprietary HPT™ (Hydropellent Technology) Coating (on palm and fingertips) keeps the glove soft and flexible in temperatures as low as -20ºC Liquid resistant to keep hands comfortable and flexible in cold applications Outstanding dexterity and grip even in cold and wet applications, thanks to its non-slip surface ThermSmart nylon and acrylic double-knitted liner provides outstanding thermal protection Breathe Smart Technology ensures 360º breathability for the hands Made with Fit Smart technology to ensure the gloves feel like a “second skin” Optional high-visibility (hi-vis) option for low light conditions You can also consider other cold-resistant, thermal protection gloves from Beaver Brands: Ninja Multi-Tech Therm365 (NITHRM365) General purpose, ‘all year round’ glove with HPTTM water-resistant coating and ThermSmart protection Contego Chillagoe Cold Wet (COCHLMECH) General purpose, all-rounder gloves with a water-resistant barrier and back-of-hand bump protection for non-cut environments AIMS' Note on Buying PPE and Workwear Hazard assessment: Identify the specific hazards you will likely be facing in your work environment. Consider potential risks such as chemical exposure, falling objects, loud noises, electrical hazards or biohazards. This assessment will guide you in selecting the appropriate PPE for the job. Appropriate materials: Different materials offer various protective qualities. Consider flame-resistant (FR) materials for fire hazards, chemical-resistant fabrics for handling hazardous liquids and high-visibility options for work in low-light environments. Compliance to occupational safety standards: Opt for PPE that meets the pertinent Australia Standard (AS), although some brands -- especially imports -- will have other compliance markings such as ANSI, OSHA, ANSI, NIOSH, oSA etc. Look for certifications on the product label to ensure the equipment has undergone rigorous testing. Proper fit and comfort: Proper fit is crucial for both comfort, dexterity and protection. Ill-fitting clothing can snag on machinery or restrict movement, potentially creating additional hazards. Choose sizes that allow for layering in cold weather without being overly bulky and consider adjustable options for items like hard hats or respirators. Maintenance and replacement: Inspect PPE before each use for signs of wear, tear or damage. Follow (and factor in) the manufacturer's instructions for cleaning and storage. Some materials may require specialised laundering, while others can be machine-washed. Check for durability to ensure the clothing can withstand frequent use and cleaning. Replace damaged or expired PPE immediately to guarantee your safety. Training: Ensure you and any employees understand how to properly use, wear, adjust, maintain and store PPE and workwear. Improper use can negate its protective benefits. For Australian hard hat standards, colours and AS/NZS 1801 compliance, see our Hard Hat Guide Australia. People Also Ask — Thermal and Cold-Resistant Gloves Q: What is the Australian standard for cold-resistant gloves? Cold-resistant gloves in Australia are assessed under AS/NZS 2161.5, which covers protective gloves against cold environments. The standard specifies test methods for resistance to convective cold (insulation value), contact cold (thermal resistance), water permeability, and dexterity. Performance levels are assigned from 0 (lowest) to 4 (highest) for each property. For general cold store and refrigeration work, a minimum convective cold insulation of Level 2 is typical; for outdoor work in extreme cold or contact with frozen materials, higher insulation and contact cold ratings are required. Q: What types of thermal gloves are used in industrial cold store environments? For cold store environments (typically −18°C to −25°C), the most common options are: (1) insulated liner gloves with a waterproof outer shell — provides both thermal protection and moisture resistance for handling wet or icy products; (2) thermal-lined gauntlet gloves for handling of large frozen goods; (3) contact cold rated gloves for handling metal components, pipes, or LPG cylinders which transfer cold rapidly to the hand. Nitrile or neoprene outer shells provide grip on wet or frosted surfaces. Dexterity requirements should be evaluated — heavier insulation reduces grip sensitivity. Q: Can I use the same thermal gloves for heat protection and cold protection? No — thermal protection gloves for heat and cold are fundamentally different products and should not be interchanged. Heat-resistant gloves use ceramic fibre, Kevlar, or aluminised fabrics to reflect or resist radiant and convective heat — they are rigid and do not insulate against cold. Cold-resistant gloves use low-conductivity fibres, foam insulation, and vapour barriers to trap body heat. Wearing heat-resistant gloves in cold environments provides inadequate protection; wearing cold-resistant gloves near heat sources can be dangerous as the insulation materials may melt or ignite. Always select PPE matched to the specific thermal hazard. Q: What gloves are required for handling dry ice or liquid nitrogen? Handling dry ice (−78.5°C) or liquid nitrogen (−196°C) requires cryogenic gloves rated for extreme cold contact. Standard cold store gloves are inadequate for these temperatures. Cryogenic gloves (such as those with thick leather outers and aluminised or foam insulation) are rated for brief contact with cryogenic liquids and cold surfaces. Crucially, cryogenic gloves must be loose-fitting — if liquid nitrogen splashes inside a tight-fitting glove, it cannot drain away and causes severe cryogenic burns. Consult the product datasheet and a safety specialist before selecting PPE for cryogenic applications. Q: How do I select thermal gloves for outdoor work in cold and wet conditions? For outdoor work in cold and wet conditions (e.g., construction, maintenance in winter, utilities), look for gloves that combine: AS/NZS 2161.5 Level 2+ convective cold insulation; a waterproof membrane or outer shell (check for waterproof rating — many thermal gloves are water-resistant, not waterproof); adequate mechanical protection for the grip rating required (AS/NZS 2161.3 cut and abrasion performance); and maintained dexterity for tool handling. Work gloves with a thermal liner and a latex, nitrile, or neoprene coated outer shell are a versatile choice. Replace gloves when the waterproofing or insulation is compromised.

How to Keep Your Chips Under Control
When it comes to best practices in machining, SECO is our first reference – an example being their piece about basic singular patterns in machining. We thought their article on How to Overcome Chips Challenges might be useful when you are doing machining and metal-cutting work. In the article, they cover: How to influence chip formation General description of basic chip types (segmented, continuous, built-up edge, shearing) Different types of basic chip cross-sections Chip breaking geometries Influence of cutting speed on chip formation They included helpful illustrations as well, such as these examples: Different types of basic chip cross sections Examples of different chip forms in various workpiece materials Basic principle of a chip-breaking geometry: In general terms, when the rake angle decreases (negative tooling), chip curvature becomes tighter, which leads to shorter, broken chips. Chip breakers serve to reduce the radius of chip curvature and thus break chips into shorter lengths. A. Chip B. Without chip breaker C. With chip breaker D. Chip breaker E. Tool F. Workpiece As a conclusion, they basically suggest that you take these steps to achieve “trouble-free chip formation”: Prioritize the process-optimization criterion: either productivity or cost efficiency. If chip formation is acceptable, go to step 5. If chips are too long, go to step 3. If chips are too short, go to step 4. If productivity is important, increase the feed. If cost efficiency is important, change the chip breaker to a stronger geometry. Keep the feed within the range of the chip-breaking geometry. Go to step 5. If productivity is important, change the chip breaker to a sharper geometry. If cost efficiency is important, reduce the feed. Keep the feed within the range of the chip-breaking geometry. Go to step 5. If cost efficiency is the priority, lower cutting speeds to improve it. If productivity is a priority, increase cutting speeds to improve it. AIMS' note on managing chips Tool geometry: Choose cutting tools with chipbreakers designed for the material you're machining. These chip-breakers introduce interruptions or curves into the cutting edge, forcing the chips to curl and break into smaller, more manageable pieces. Also, selecting the correct nose radius for your insert can help control chip formation. Cutting parameters: Adjust your feed rate and cutting speed. Increasing feed rates often helps break chips, while higher cutting speeds can produce thinner and more manageable chips. However, be careful not to push speeds and feeds beyond the tool's capabilities, as this can lead to tool breakage or poor surface finish. Refer to recommended parameters from your tooling manufacturer as a starting point. Coolant: High-pressure coolant directed at the cutting zone can effectively break chips and flush them away, improving chip control. Ensure your coolant system is working optimally and use the correct coolant type for the job. Machine rigidity: A rigid machine setup helps reduce vibrations that can lead to unpredictable chip formation. Make sure your workpiece and tooling are clamped securely to minimise unwanted movement.

Disposal: Dispose of used abrasives properly per local regulations. People Also Ask — Metal Chip & Swarf Control Q: Why is controlling metal chips important? Swarf control matters for safety, quality and productivity. Long, stringy chips are sharp and hot and can wrap around tooling, the workpiece or the operator, causing injuries and entanglement. A build-up of chips around the cut interferes with the tool, re-cuts and scratches the finished surface, and can jam machine ways and conveyors. Piles of swarf are also a slip and laceration hazard around the machine. Keeping chips short, cleared and contained protects the operator, preserves surface finish and tool life, and keeps the machine running without stopping to clear blockages. It is a core part of efficient, safe machining. Q: What causes long stringy chips instead of short ones? Chip form is governed by the material, the cutting parameters and the tool geometry. Ductile materials like low-carbon steel and aluminium naturally tend to form long, continuous chips, while harder or more brittle materials break into short chips. Cutting too slowly, with too light a feed, or with a tool that has no chip-breaking geometry encourages long curling chips. Increasing the feed, using a tool with a chipbreaker, and running the right speed all help the chip curl tightly and snap into manageable pieces. So when you are fighting bird's-nests of swarf, the levers are feed rate, tool geometry and cutting speed. Q: How do chipbreakers help control swarf? A chipbreaker is a moulded step or groove on the tool's cutting face that forces the chip to curl tightly as it forms. Once the chip is curled into a small enough radius it becomes brittle and snaps off into short, manageable pieces instead of streaming away in long ribbons. Many indexable inserts come with chipbreaker geometries matched to particular materials and feed ranges. Short chips are safer to handle, clear more easily, and are less likely to wrap around the tool or mar the surface. Choosing an insert with the right chipbreaker for the job is one of the most effective ways to control swarf at the source. Q: How does cutting fluid help with chip control? Coolant and cutting fluid help in two ways. First, a well-aimed flow flushes chips out of the cut and away from the work zone, stopping them piling up, re-cutting and scratching the finish. Second, by cooling and lubricating the cut, fluid influences how the chip forms and reduces built-up edge, which keeps chips breaking cleanly. High-pressure through-tool coolant is especially effective at blasting chips clear in deep holes and pockets. So beyond protecting the tool, directing coolant properly is a practical chip-management tool — it keeps the cutting zone clear and the swarf moving toward where you want to collect it. Q: What is the safe way to clear metal swarf? Never clear chips by hand or while the machine is running. Stop the spindle and use a proper tool — a chip rake, hook, brush or shovel — and wear gloves and eye protection, because swarf is sharp and often hot. Long stringy chips should be pulled clear with a hook rather than grabbed. Collect swarf into bins promptly so it does not build up into a hazard underfoot, and keep walkways clear. For ongoing production, chip conveyors and guarding manage swarf automatically. Treating swarf as the sharp, hot waste it is — and only clearing it with the machine stopped and the right tool — prevents the cuts and burns that are so common around machining. Need loc-line?

Are Klingspor Abrasive Tools Safe to Use?
As a user of high-speed abrasive tools, you may have already seen the oSa logo. (You may have also wondered why you couldn’t find the Australian Standard details you’re already familiar with on Klingspor products.)oSA stands for the Organisation for the Safety of Abrasives. It’s an internationally recognized authority on cutting and grinding tools founded in Germany in 2000. That’s when leading producers of high-grade abrasive products came together to document the high safety standards of their products, to ensure that the quality of their products remains consistently high in the interests of abrasive product users. oSa members are committed to ensuring the adherence to safety standards and sustaining quality assurance. Klingspor is an oSa member. What are the significant differences between the requirements according to oSa and the Australian Standards AS1788.1? The main differences are the requirements for product labels, as well as the reference to the use of wheel flanges with identical diameter. The regulations of the oSa certification require the same facts but refrain from labeling the product in the same way. There are two reasons for these differences: Machine manufacturers already provide hand-held grinding tools with the correct flanges ex-works. The wide variety of fixing systems and flange types available these days does not allow comprehensive and accurate documentation on the product label. This is the only requirement where the guidelines of the Australian Standard are more demanding than the ones of oSa. Update: AS 1788 is now superseded by AS EN 12413:2022 as of December 2022. In the following, you will find some examples to outline why the demands of the oSa certification (based on European standard EN 12413) are far stricter than the Australian Standard AS1788.1. Scope of testing The Australian Standard does not stipulate the scope of a product sample test. The amount of testing relies on the manufacturer’s discretion. The oSa standard requires that one out of every 1,000 discs must be tested to the point of destruction. All tests in accordance with oSa are process-controlled throughout the manufacturing process: Bursting test: The Australian Standard test requires only 1.5 times the maximum operating speed for all diameters. For abrasive tools on hand-held, portable grinding machines, EN 12413 stipulates a generally higher test speed which is defined in relation to the diameter. Side load / Impact test: The Australian Standard requires no side load/impact tests. In contrast, according to EN 12413, the side load is regularly checked, depending on the diameter and application (free-hand or stationery). Run-out tolerances: The Australian Standard gives no run-out tolerances. On the contrary, EN 12413 determines the run-out tolerances (deviation concentricity from axis) depending on the diameters. Tolerance of thickness: The Australian Standard specifies no thickness tolerances. EN 12413 demands tolerance values according to the nominal value stated. All high-quality abrasive products of the member companies are subject to the stringent requirements of oSa. These products are manufactured and tested based on European safety standards. Therefore, products with the oSa label assure a high-quality production process and high standards of safety checking. So, are Klingspor’s abrasive tools safe to use? Yes, not only are they safe, but they are also even safer! Klingspor is a manufacturer of the highest quality abrasive tools and accepts responsibility for its products. Therefore, Klingspor holds Global Product Liability Insurance for its entire product range. As a user of abrasive tools with an oSa label, you can be sure that Klingspor products meet the highest precautionary measures and latest production standards that exist around the world. AIMS' Note on Safe Use of Abrasives Inspection: Before using any abrasive disc or wheel, carefully inspect it for cracks, chips or damage. Beware that damaged abrasives can shatter at high speeds and cause serious injury to you or other people nearby. Some brands indicate ‘use by’ dates, which is important because some abrasives deteriorate over time. Mounting: Ensure proper and secure mounting of the abrasive onto the tool, using the correct flanges and blotters as needed. Never exceed the maximum RPM rating of the abrasive. Always unplug or disconnect power tools (eg power grinders) before changing abrasives. PPE: Always use machine guards designed for the specific abrasive tool. Wear essential safety gear, including safety glasses or goggles or a full-face shield for maximum protection. Gloves, ear protection and dust masks / respirators are often necessary, depending on the material being worked on and the type of abrasive you are using. Controlled usage: Start tools smoothly, allowing them to reach full speed before applying them to the workpiece. Avoid excessive pressure that can overheat or break the abrasive. If an abrasive is discolored or smells burnt, replace it. Environment: Be mindful of sparks and debris generated by abrasives. Use dust extraction equipment to minimise exposure to harmful dust. Work in a well-ventilated area clear of flammable materials. Maintenance: Keep your abrasives clean, sharp and properly maintained. Store them in a safe and organized place when not in use. Disposal: Dispose of used abrasives properly according to best practices and local regulations. For sandpaper selection (grit, backing, material), see our sandpaper range. For the broader grinding wheel safety picture across all brands — wheel types, RPM matching, mounting, PPE under AS 1788.2 — see our Grinding Wheel Safety: Selection, Mounting & AS 1788 guide. People Also Ask — Safe Use of Abrasives Q: What PPE is required when using angle grinders and cutting discs? When operating an angle grinder with cutting or grinding discs, the minimum PPE required under Safe Work Australia guidance and AS/NZS 1336 includes: a full-face shield (AS/NZS 1337) over safety glasses — not glasses alone; hearing protection rated for the noise level (AS/NZS 1270); P2 dust respiratory protection where silica-containing materials are being cut (AS/NZS 1716); leather or cut-resistant gloves; and flame-resistant long-sleeved clothing or an apron. Always use the correct guard — removing grinding wheel guards is a serious safety violation and the leading cause of serious angle grinder injuries. Q: What is the maximum RPM rating rule for abrasive discs? The disc's maximum operating speed (RPM) must be equal to or greater than the free-running RPM of the angle grinder at the specified disc diameter. The disc's RPM rating is printed on the label. For example, a 125mm disc rated to 12,200 RPM must only be used on a 125mm grinder whose free speed does not exceed 12,200 RPM. Exceeding the disc's rated speed can cause catastrophic disc disintegration. Always check that the disc diameter and RPM rating matches the grinder specification before mounting. This requirement is defined in AS 1788 and reinforced in Klingspor's product documentation. Q: How should abrasive discs and grinding wheels be stored? Abrasive products must be stored: in a dry environment at a temperature between 5°C and 40°C (high humidity and temperature cycling degrade resin bonds); horizontally for large grinding wheels to prevent warping; away from solvents, acids, and chemicals that attack the resin bond; protected from physical impact that could cause concealed cracks. A cracked disc that appears undamaged visually can disintegrate during use. Before mounting any abrasive disc or wheel, perform a ring test (tap with a light object — a clear ring indicates an undamaged wheel; a dull thud indicates a crack). Q: What is the difference between a Type 1 (flat) and Type 27 (depressed-centre) grinding disc? Type 1 discs are flat and are designed for cutting — the cutting edge is the disc's perimeter and the disc must be presented at close to 90° to the workpiece. Type 27 discs have a raised (depressed) centre hub, designed for grinding and surface blending at shallow angles (typically 10–30° to the workpiece surface). Using a cutting disc for grinding or a grinding disc for cutting increases the risk of disc breakage. Klingspor and other manufacturers clearly mark Type 1 (cutting) and Type 27 (grinding/blending) on each disc — always match the disc type to the application. Q: What silica dust controls are required when cutting concrete or stone with abrasives? Respirable crystalline silica (RCS) dust from cutting concrete, stone, fibre cement, and masonry is a known cause of silicosis — an irreversible and potentially fatal lung disease. Safe Work Australia's WHS Regulations and the National Code of Practice for the Management and Control of Asbestos in the Workplace specify a WES (Workplace Exposure Standard) of 0.05 mg/m³ for RCS. Effective controls in hierarchy order: (1) use a wet cutting method (water suppression reduces dust by 85–90%); (2) use on-tool extraction (vacuum attached to the grinder hood); (3) use a P2 or P3 half-face respirator as the final barrier — never as the sole control.

Grinding Wheel Safety: Selection, Mounting & AS 1788
Angle grinders sit at the top of Safe Work Australia's serious-injury list every year. Most of the harm comes from wheel selection mistakes, missing or removed guards, wrong RPM, or operators not bracing for kickback. None of those failure modes are mysteries — they all sit inside AS 1788.2 Abrasive products — Safety requirements for the use of abrasive products, which is the controlling standard for grinding wheel use in Australia. This guide walks through how to choose the right wheel, inspect it before mounting, match it to the grinder's RPM, mount it correctly, operate it safely, and what PPE is non-negotiable. It's written for fabricators, mechanical fitters, automotive workshops, plumbers, electricians, maintenance teams, and the DIYer doing more than the occasional cut. If you cut concrete, stone or stainless steel, the silica and manganese dust sections are essential reading. For wheel selection by spec code, type and grit, our companion Grinding Discs & Wheels: Types, Spec Code & Selection Guide covers the product side in depth. This guide is the safety hub. Grinding Wheel Quick Safety Checklist Run this checklist before every cut or grind: # Check 1 Wheel max RPM ≥ grinder rated RPM. Never the other way around. 2 Wheel diameter, thickness and bore match the grinder spec. 3 Wheel is the right type for the job (cut-off vs grinding vs flap). 4 Visual inspection: no cracks, chips, blotter damage, or moisture marks. 5 Ring test on vitrified wheels — clear ringing tone, not a dull thud. 6 Correct flanges and blotters fitted. Locking nut firm — never over-tightened. 7 Guard fitted, positioned between the wheel and operator. 8 Workpiece secured in a vice or with clamps. Never hand-held. 9 Full PPE on: face shield + safety glasses, P2 minimum respirator, hearing, leather gloves and apron, enclosed boots. 10 Area clear of flammables. Hot work permit in place if required. 11 Two-handed grip. Side handle fitted and in use. 12 Let the wheel reach full speed before contact. Let it stop fully before setting down. The AS 1788.2 Framework AS 1788.2 Abrasive products — Safety requirements for the use of abrasive products is the Australian Standard that governs how grinding and cutting-off wheels must be selected, mounted, used and stored. It applies to depressed centre wheels, cutting-off wheels, straight wheels, and bonded abrasive products used on portable and bench grinders. The standard sits alongside several other AS/NZS standards that all apply when grinding work is happening: AS/NZS 1336 — Eye and face protection — Guidelines: selection guidance for face shields, goggles and glasses. AS/NZS 1337 series — Eye protectors: performance and marking. Look for the AS/NZS 1337.1 mark on safety glasses and AS/NZS 1337.6 for prescription versions. AS/NZS 1270 — Acoustics — Hearing protectors: SLC80 Class system for muffs and plugs. AS/NZS 1715 — Selection, use and maintenance of respiratory protective equipment and AS/NZS 1716 — Respiratory protective devices: the P1/P2/P3 filter classifications. AS/NZS 2161 series — Occupational protective gloves: general requirements and mechanical hazards (EN 388 family). AS 1788.2-1987 (the grinding wheels application/operation standard remains in force). AS/NZS 1337.1:2010+Amdt 2:2018, AS/NZS 1716:2012 (R2024), AS/NZS 1270:2002 (R2014). WHS legislation in every Australian state and territory makes compliance with these standards a duty for PCBUs (Persons Conducting a Business or Undertaking). Practically that means: train operators, supply the right wheels and PPE, maintain the tools, and keep records. Wheel Types — At a Glance Pick the wrong wheel type and you've broken the standard before you've even started. The four common bonded abrasive types you'll meet on a portable grinder are: Type Profile Use Common bonded thickness Type 1 Straight, flat Cutting-off (bench cut-off saws, some portables) 1.6–3.2 mm Type 27 Depressed centre Grinding (most common on 4½–9″ angle grinders) 6.0–6.4 mm Type 41 Flat cut-off, reinforced Cutting-off ONLY — never use on the side 1.0–3.2 mm Type 42 Depressed centre cut-off Cutting + light grinding on the edge — still primarily a cutting wheel 2.5–4.5 mm Flap disc Overlapped abrasive flaps on backing plate Grinding + finishing in one — gentler on the workpiece than a Type 27 n/a For the deeper selection logic (grit, bond, application by metal type), see our Grinding Discs & Wheels Selection Guide. For flap disc-specific selection, see the Flap Disc & Abrasive Sanding Guide. Browse current stock: Cutting Wheels, Grinding Wheels & Accessories, Flap Discs, or the full Abrasives range. Wheel Specifications — Diameter, Thickness, Bore Every wheel is stamped with three physical numbers that must match the grinder you're putting it on. Get any of the three wrong and the wheel either won't fit or will fail in service. Diameter The wheel's outside diameter — 100 mm (4″), 115 mm (4½″), 125 mm (5″), 180 mm (7″), 230 mm (9″) are the common Australian sizes. The grinder's guard is sized for a specific diameter range. A 4½″ guard cannot safely cover a 5″ wheel. Thickness Cut-off wheels are typically 1.0–3.2 mm. Grinding wheels (depressed centre) are 6.0–6.4 mm. A 1 mm cut-off wheel will cut faster and waste less metal but is more fragile under side load — and side load on a cut-off wheel is forbidden anyway (see below). Bore The centre hole. The Australian standard bore for angle grinder wheels is 22.23 mm (sometimes labelled 7/8″). Some bench wheels use 31.75 mm (1¼″) or 25.4 mm (1″). Never bore out, ream, or shim a wheel to fit a spindle it wasn't manufactured for. Matching Wheel RPM to Grinder RPM This is the single most ignored safety rule in workshops. The wheel's maximum operating RPM must always equal or exceed the grinder's rated speed. Run a wheel above its rated RPM and the centrifugal stresses can exceed the bond strength — the wheel breaks apart. Grinder size Typical no-load RPM Wheel RPM required 4″ (100 mm) 13,500–15,300 ≥ rated grinder RPM 4½″ (115 mm) 11,000–13,300 ≥ rated grinder RPM 5″ (125 mm) 11,000–12,200 ≥ rated grinder RPM 6″ (150 mm) 9,000–10,000 ≥ rated grinder RPM 7″ (180 mm) 8,000–8,500 ≥ rated grinder RPM 9″ (230 mm) 6,500–6,650 ≥ rated grinder RPM The maximum operating speed is stamped on the wheel itself and printed on the blotter (the paper washer bonded to the wheel face). If you can't read either, do not mount the wheel. Pre-Use Inspection — Visual and Ring Test Visual inspection Before every mount, look at the wheel for: Hairline cracks running from the bore outward (the most dangerous fault — these propagate under load) Chips on the edge greater than ~3 mm Damaged or partly detached blotters Moisture stains (water weakens vitrified bond — wheel is compromised) Date code or batch markings — some resin-bonded wheels carry an expiry date because resin degrades over time The ring test (vitrified wheels only) Suspend the wheel through the bore on a wooden dowel or screwdriver shaft. Tap the wheel gently with a non-metallic implement (the wooden handle of another tool) at about 45° from each side. A sound wheel rings clearly. A cracked wheel produces a dull or flat thud. Repeat from four positions around the wheel. The ring test does not work on organic (resin or rubber) bonded cut-off wheels — they always sound dull. Visual inspection plus the date code is the assessment method for those. Wheel Storage Wheels are not consumables you toss in a drawer. Store them properly and they last; store them badly and they fail in service. Keep them in the original packaging until first use Store flat (stacked carefully with thin separators) or vertical on edge in a rack Never stack heavy items on top — even cardboard boxes Keep them dry. Humidity attacks vitrified wheels and corrodes the metal reinforcement on cut-off wheels Keep them away from solvents, fuels and oils — these attack resin bonds Storage temperature 5–30 °C. Sub-zero or above 40 °C accelerates resin degradation First-in-first-out rotation — use the older stock before the newer when both are within date A simple wall-mounted timber or steel rack with vertical slots is the standard workshop solution. Browse Abrasives for current stock if your wheels are aged past their date code. Mounting the Wheel Mounting is where small mistakes become serious failures. The procedure: Unplug or remove the battery — never change a wheel on a live tool Press the spindle lock (most angle grinders), or hold the spindle with a pin spanner Loosen the locking flange with the manufacturer's pin spanner. Use the right spanner — pliers will round the flange Remove the existing wheel. Wipe the spindle, inner flange and locking flange clean of swarf and debris Inspect the new wheel (visual + ring test) Place the inner flange on the spindle Place the wheel against the inner flange — orientation depends on wheel type (Type 27 depressed centre faces outward) If a blotter or paper washer is supplied bonded to the wheel, leave it in place; if it's loose, fit it between the wheel and the locking flange Fit the locking flange and tighten with the pin spanner — firm only, not over-tight. Over-tightening distorts the flanges and pre-stresses the wheel, weakening it Refit the guard and confirm it covers at least 180° of the wheel between the wheel and the operator Restore power. Run the grinder at full speed (with the wheel pointed away from the operator) for at least 30 seconds before first use — listen for vibration, wobble, or unusual noise Safe Operation — Cut-Off vs Grinding Cut-off wheels Warning: Cut-off wheels (Type 1 and Type 41) are only safe to use on the edge. Never load them on the flat side. The wheel is engineered to take radial compression, not side loading. Side loading a cut-off wheel will break it. The fragments leave the wheel at the wheel's surface speed — for a 4½″ wheel at 13,000 RPM that's around 250 km/h. Cut-off technique: Mark the cut line clearly Secure the workpiece in a vice or with clamps so the offcut won't pinch the wheel Let the wheel reach full speed Apply the wheel to the work at 90° to the cut line, only on the edge Light pressure — let the wheel cut at its own speed. Forcing the wheel slows it and overheats the bond If the wheel starts to pinch in the cut, stop and re-secure the offcut Withdraw before letting off the trigger; let the wheel coast down clear of the work Grinding wheels (Type 27) Grinding wheels are designed to work on their face at a shallow angle to the workpiece: Working angle: 15–30° face to workpiece (above 30° lifts the wheel; below 15° tries to use the wheel like a cut-off — both wrong) Sweep the wheel across the work; don't rest it in one spot Light pressure — heat builds quickly and discolours both wheel and workpiece Two-handed grip with the side handle fitted Workpiece secured in a vice or clamped — never hand-held Flap discs Flap discs are more forgiving than Type 27 wheels. The flap structure lays flat against the work so the working angle can be 5–15° (gentler grind, smoother finish). They're a good choice for finishing welds and removing surface rust. See the dedicated Flap Disc Guide for selection. Kickback Hazards Warning: Kickback is the most common cause of serious angle grinder injury. The wheel grabs the workpiece — either because the wheel binds in a cut, hits a hard inclusion, or you angle it into a corner — and the grinder is thrown back violently at the operator. With a 4½″ grinder this can put the spinning wheel into the operator's face or throat in a fraction of a second. What causes kickback: The wheel pinches in the cut as the offcut sags Plunge-cutting into corners or against a step where the wheel binds Using the wrong section of the wheel (top half of the wheel grabs more than the bottom) Twisting the grinder out of the cut line Working with a damaged wheel that catches in the cut How to prevent it: Two-handed grip, always. Side handle fitted to the threaded port — not optional Position your body to the side of the wheel's rotation plane, not in line with it Brace your stance — feet shoulder-width, knees soft Cut on the underside of the wheel (the part rotating away from you) on free work; cut on the topside when the work is fixed Plan the cut so the offcut falls away clean, not pinches For deep cuts, multiple shallow passes — not one deep one Keep both hands on the tool until the wheel has fully stopped Wheel Breakage — Why Face Protection Matters Warning: A 4½″ wheel at 13,000 RPM has a surface speed of approximately 78 m/s — about 280 km/h. Fragment velocity in a wheel break is in that order. Safety glasses alone do not stop a wheel fragment to the face. AS/NZS 1336 guidance is face shield + safety glasses combined. Wheels can break from: Exceeding the rated RPM Side loading a cut-off wheel Mounting a cracked or moisture-damaged wheel Over-tightening the locking flange Pinching in the cut Striking the workpiece or another hard object at speed Fragments travel in the plane of the wheel — which is why the guard MUST be positioned between the wheel and the operator. The guard contains roughly half the wheel's plane; the rest is contained by distance, body positioning, and PPE. PPE — What's Required The PPE stack for grinding work, working from head down: Body part PPE Standard Eyes Safety glasses with side shields (medium impact rating minimum) AS/NZS 1337.1 Face Full face shield over the safety glasses AS/NZS 1337.1 / AS/NZS 1336 guidance Hearing Class 4 or 5 earmuffs OR earplugs depending on tool noise (4½″ grinders typically 95–105 dB(A)) AS/NZS 1270 Respiratory P2 disposable minimum; P3 for stainless, concrete, stone, or extended dusty work AS/NZS 1715 / 1716 Hands Leather rigger gloves OR heavy mechanical cut-resistant gloves (Cut Level C or D under EN 388) AS/NZS 2161 series Body Cotton drill or leather welding-style jacket. No synthetics (melt risk from sparks) — Legs Cotton drill workwear or leather chaps for heavy work. Cuff inside the boot — Feet Enclosed safety boots with steel or composite toe cap, AS/NZS 2210.3 marked AS/NZS 2210.3 Browse current PPE stock: Eye Protection, Face Protection, Ear Protection, Respiratory Protection, Welding Gloves, Cut-Resistant Gloves, Hand Protection, Workwear, and the broader Safety range. For the deep-dive on glove selection and cut levels, see the Work Gloves Guide. For respirator P1/P2/P3 selection, see the Respirator Guide. For lens types and lens ratings, see the Safety Glasses Guide. Silica Dust — The Silent Killer Warning: Cutting concrete, brick, stone, render, tile, fibre cement, or composite stone releases respirable crystalline silica (RCS). Long-term exposure causes silicosis — irreversible lung scarring — and increases lung cancer risk. The Safe Work Australia workplace exposure standard for RCS is 0.05 mg/m³ over 8 hours. Dry-cutting concrete with a 4½″ grinder can produce RCS concentrations many times that level within minutes. If you cut any silica-bearing material with a grinder: Use wet cutting wherever possible. Diamond blades with water feed suppress dust at source If dry cutting is unavoidable, attach on-tool dust extraction (M or H class vacuum) with a shrouded guard Minimum respirator: P2 half-face. For extended dry cutting: P3 half-face or full-face PAPR Wet down the work area before, during and after — don't sweep dry; HEPA vacuum Change out of dusty clothing before leaving site; don't take dust home Australian state regulators are auditing silica compliance hard since 2024 — keep records of training, dust controls, and air monitoring where applicable Manganese dust on stainless Grinding or cutting stainless steel releases manganese, chromium and nickel oxides. Manganese has a respirable WES of 0.02 mg/m³ TWA — extremely low. P2 minimum, P3 or PAPR preferred. Adequate ventilation or local exhaust is essential for extended stainless work. Hot Work Considerations Grinding sparks travel further than people expect — typical 8–10 m, further with high-carbon steel or stainless. Sparks at the end of their flight can still ignite paper, sawdust, oily rags, solvent vapour, or LPG/petrol vapour. Before any grinding work: Clear flammables and rags within a 10 m radius of the grinding position Cover or wet down any flammables that can't be moved (timber framing, paint stores) Confirm fire extinguishers are within reach — ABE or water mist depending on what's nearby If working in a permit area (refineries, fuel storage, confined spaces, hot work zones, industrial sites), get the hot work permit in writing first Brief any fire watch on what to do and where the extinguisher is Inspect the area 30+ minutes after work finishes — embedded sparks can smoulder before they ignite Our dedicated guide: When You Need a Hot Work Permit. Companion welding safety standards: Welding Safety Guide: PPE, Fume, Hot Work & AS Standards. Run-Up & Coast-Down Two simple discipline rules that prevent the majority of wheel-engagement injuries: Run-up After mounting a new wheel, run the grinder at full no-load speed for at least 30 seconds with the wheel pointed away from the operator and any other people. Listen for vibration, wobble, unusual noise. If the wheel is going to fail from a manufacturing defect, undetected crack, or moisture damage, this is when it does — and you want that energy going into the guard, not into your work. Coast-down When work is finished: Lift the wheel clear of the workpiece BEFORE releasing the trigger Let the wheel coast to a complete stop in the air Do not set the grinder down with the wheel still spinning — wheels grab into benches, fly off corners, and snag clothing or cables Keep both hands on the tool until the wheel is stopped Most grinders coast for 8–15 seconds. Patience here is free; broken wheels and damaged work are not. When NOT to Use the Grinder Stop and reassess if any of these apply: Wrong wheel for the job — never grind on a cut-off wheel, never cut on a Type 27 grinding wheel's side Wheel rated below grinder RPM Damaged wheel — any crack, chip > 3 mm, blotter damage, or moisture mark Past date code on resin-bonded wheels Guard missing, broken, or modified — removing the guard to "see better" is a frequent fatality cause; do not Side handle missing — kickback control fails without the second grip Trigger or lock-on switch sticking or modified Power cable damaged or cord switch faulty Battery showing damage, swelling or excessive heat on cordless tools Operator untrained, fatigued, or under medication that affects co-ordination Workpiece unable to be secured — never hand-hold work Flammable atmosphere nearby — fuel station, solvents, dust risk — without a permit and controls AIMS' Note on Grinding Wheel Selection The hardest part of buying grinding wheels is matching the wheel to the job and the grinder you're using.

Phone (02) 9773 0122 or use our contact page. Grinding Wheel Safety FAQ What is AS 1788.2 and why does it matter? AS 1788.2 is the Australian Standard that governs the safe use of abrasive products including cutting-off and grinding wheels. It sets the rules for selection, inspection, mounting, RPM matching, guarding, and storage. WHS legislation in every Australian state and territory makes PCBUs (employers and self-employed contractors) responsible for ensuring compliance — train operators, supply correct PPE, and maintain tools. Can I use a cut-off wheel for grinding if I'm careful? No. Cut-off wheels are engineered for radial loading only — applying side pressure (which is what grinding does) can break the wheel. A 4½″ wheel at 13,000 RPM throws fragments at around 250 km/h. Use a Type 27 depressed centre wheel or a flap disc for grinding. Type 42 is the only wheel rated for both cutting on the edge and light grinding, and even then it's primarily a cutting wheel. What RPM should my wheel be rated for? The wheel's maximum operating RPM must always be equal to or greater than the grinder's rated no-load speed. For a 4½″ angle grinder at 12,000 RPM, the wheel must be rated 12,000 RPM or higher. The wheel's maximum RPM is stamped on the wheel itself and printed on the blotter. If you can't read either, don't use the wheel. How do I do a ring test? Suspend the wheel through the bore on a wooden dowel or screwdriver shaft so it hangs free. Tap the wheel gently with a non-metallic implement (the wooden handle of another tool) at about 45° from each side. A sound wheel rings clearly. A cracked wheel produces a dull or flat thud. Repeat from four positions. Ring test works on vitrified wheels only — organic resin or rubber bonded cut-off wheels always sound dull, so they're assessed by visual inspection plus the date code instead. Why is over-tightening the locking flange a problem? Over-tightening distorts the flanges, which pre-stresses the wheel before it even starts spinning. That stress adds to the centrifugal stress in service and can take the wheel above its strength limit at normal operating RPM. Tighten the locking flange firm only — use the manufacturer's pin spanner, not pliers or a hammer. What PPE is essential for grinding? Safety glasses (AS/NZS 1337.1 medium impact minimum) plus a full face shield over them, hearing protection (Class 4 or 5 muffs or plugs), P2 respirator minimum (P3 for stainless, concrete, stone, or extended dry work), leather rigger gloves or heavy cut-resistant gloves (EN 388 Cut Level C or D), cotton drill or leather workwear, enclosed safety boots AS/NZS 2210.3. Safety glasses alone do not stop a wheel fragment — face shield is non-negotiable. Can I cut concrete with an angle grinder? Yes, with a diamond cut-off blade rated for the grinder's RPM and proper silica dust controls. Wet cutting is preferred — diamond blades with water feed suppress respirable crystalline silica at source. If dry cutting is unavoidable, use on-tool dust extraction (M or H class vacuum) with a shrouded guard, plus P2 respirator minimum (P3 preferred). Respirable crystalline silica has a workplace exposure standard of 0.05 mg/m³ over 8 hours — dry cutting with a 4½″ grinder can exceed that within minutes. What causes kickback and how do I prevent it? Kickback happens when the wheel grabs the workpiece — usually because the wheel pinches in a cut as the offcut sags, the wheel hits a hard inclusion, or you angle into a corner where the wheel binds. Prevention: two-handed grip with the side handle fitted, stand to the side of the wheel's rotation plane (not in line), brace your feet, plan the cut so the offcut falls away clean, and for deep cuts use multiple shallow passes rather than one deep one. How long do grinding wheels last in storage? Vitrified bonded wheels are dimensionally stable for years if stored dry, away from solvents, and at 5–30 °C. Resin-bonded wheels (most cut-off wheels) typically carry a date code and should be used within 2–3 years of manufacture — resin degrades over time, even unused. Check the date code stamped on the wheel or printed on the blotter. Rotate stock first-in-first-out. Can I remove the guard to see the work better? No. Removing the guard is one of the most common causes of fatal angle grinder injuries. The guard contains roughly half the wheel's plane in a break event, and positions the wheel away from the operator's body. If you can't see the cut line clearly, change your body position, add lighting, or use a smaller wheel — never remove the guard. What's the difference between a P2 and P3 respirator? P2 respirators filter at least 94% of airborne particles down to 0.3 microns; P3 filters at least 99.95%. For most grinding on mild steel, a P2 disposable half-face is adequate. For stainless (manganese, chromium oxides), concrete (silica), or extended dry work, step up to P3 — half-face or full-face PAPR. Both must comply with AS/NZS 1716 and be selected per AS/NZS 1715 fit and use guidance. Full P1/P2/P3 selection in our Respirator Guide. Do I need a hot work permit to use an angle grinder? Depends on where you are. In refineries, fuel storage areas, confined spaces, gas pipeline corridors, or sites under a formal hot work program, yes — a permit is required. In a normal workshop or open site, no, but you still need a fire watch, cleared work area (10 m radius minimum), and extinguishers within reach. Our Hot Work Permit guide walks through where permits apply. How often should I replace my grinding wheel? When it's worn to the manufacturer's minimum diameter (usually marked or readable as a coloured ring inside the wheel), when it's been visually damaged, when the date code has passed (for resin-bonded), or when the cut quality has dropped to the point where you're forcing the wheel. Don't keep undersized wheels in service — the smaller the wheel, the higher the RPM relative to its strength margin. Are flap discs safer than Type 27 grinding wheels? Flap discs are easier and gentler to use — the overlapped abrasive flaps lay flat against the workpiece so the working angle can be 5–15° rather than 15–30°. They're also less prone to kickback. But the same PPE rules apply, the same RPM matching applies, and the same guard and side handle requirements apply. They're not a substitute for proper technique. Can apprentices use angle grinders? Yes, once trained and competent. WHS rules require apprentices and trainees to be trained, supervised, and assessed as competent before unsupervised use. PCBUs must keep training records. AIMS recommends each apprentice does at least 5–10 hours of supervised grinding work before being signed off, with progressive sign-off on cut-off, grinding, flap disc, and concrete cutting tasks separately. People Also Ask — Grinding Wheel Safety Q: What is the ring test and why is it mandatory before mounting a grinding wheel? The ring test involves gently tapping the wheel with a non-metallic mallet and listening for a clear ring. A dull thud indicates a crack — a cracked wheel must never be mounted. Centrifugal force can cause a cracked wheel to disintegrate at operating speed. Q: Why must the wheel's maximum rated RPM match or exceed the grinder's RPM? If a wheel's maximum RPM is lower than the grinder's operating speed, centrifugal force at speed exceeds what the wheel's bond is designed to withstand and can cause the wheel to burst — projecting fragments at very high velocity. Always check and match RPM ratings. Q: What is kickback and how is it prevented during grinding? Kickback occurs when the wheel catches in the cut and the grinder is violently thrown back toward the operator. It is prevented by maintaining a firm two-hand grip, keeping the angle correct for the application, using the guard, and never using the side of a cut-off disc for grinding. Q: Why must the angle grinder guard never be removed? The guard deflects wheel fragments away from the operator if a wheel disintegrates, and directs sparks away from the face. Removing it is a breach of safe work practice and violates the AS 1788.2 framework for abrasive wheel use. Many serious injuries are caused by unguarded grinders. Q: What PPE is required when using angle grinders and cutting discs? A full face shield worn over safety glasses, hearing protection, leather or cut-resistant gloves, and clothing that covers exposed skin to protect against sparks and fragments. When cutting masonry, concrete, or stone, a P2 dust mask or respirator is required for silica dust.

Enhancing Workplace Safety: Strategies for Effective Asbestos Hazard Management in Industrial Settings
This guest post is written by Sebastian Tiller, who is the General Manager at Octfolio. He is passionate about making workplaces safer for everyone, one hazard at a time. Asbestos hazard management is crucial in industrial settings due to its widespread use and the severe health risks associated with exposure. Effective management not only ensures compliance with health and safety regulations but also protects workers from long-term health issues. Industries must prioritise this to maintain a safe work environment and uphold their reputation for safety standards. In this article, we discuss: Understanding asbestos hazards Regulatory framework (the legal framework surrounding asbestos management) Identification and assessment Asbestos management plan Training and awareness Safe removal and disposal Protective equipment and tools (for handling asbestos) Regular monitoring and health surveillance Understanding asbestos hazards Asbestos refers to a group of naturally occurring fibrous minerals known for their durability, fire resistance, and insulating properties. These fibers are microscopic, resilient to chemical and thermal degradation, and non-biodegradable, making them useful yet hazardous. Historically, asbestos was used in numerous industrial applications, including insulation, fireproofing, and sound absorption. It was common in building materials like roofing shingles, ceiling and floor tiles, cement products, and automotive parts like brake pads. Despite its hazardous nature, these applications took advantage of its durability and resistance to heat. However, asbestos exposure is linked to severe health risks, including asbestosis, lung cancer, and mesothelioma, a rare form of cancer. These risks are heightened in industrial settings where asbestos-containing materials may be disturbed. Long-term exposure significantly increases these health risks. Regulatory framework The legal framework surrounding asbestos management includes specific standards and regulations aimed at minimising exposure and ensuring safe handling. Laws mandate regular risk assessments, proper training for handling asbestos, and strict guidelines for removal and disposal. Non-compliance with asbestos regulations in industrial settings can lead to severe consequences, including heavy fines, legal action, and reputational damage. More importantly, it risks the health and safety of workers, potentially leading to life-threatening illnesses. Hence, adherence to these regulations is not just a legal obligation but a moral imperative. Identification and assessment Effective risk assessment techniques in industrial premises involve a thorough inspection for asbestos-containing materials (ACMs), evaluating their condition, and determining the likelihood of disturbance. This process often includes air quality testing and material sampling. Identifying potential ACMs requires knowledge of common asbestos applications and visual inspections. ACMs are often found in older buildings' insulation, tiles, and certain equipment. Professionals use various methods, including historical building records and sampling, to identify these materials accurately. Asbestos management plan An effective asbestos management plan includes a comprehensive inventory of ACMs, risk assessments, control measures, and a schedule for regular re-assessments and monitoring. It should also outline procedures for emergencies and detail training requirements for employees. This plan serves as a blueprint for maintaining safety in the presence of asbestos. Efficient record-keeping and labeling of ACMs are vital for safety. Records should include details of the location, condition, and any work done on ACMs. Labeling helps in quickly identifying these materials, ensuring that they are handled correctly, and reducing accidental exposure. Training and awareness Training in safe handling practices and emergency response procedures is essential for employees working with or around asbestos. This training should include the proper use of personal protective equipment, safe work practices to minimize fiber release, and actions to take in the case of accidental exposure or discovery of undisturbed ACMs. Increasing workplace awareness involves regular training sessions, displaying informational posters, and providing easy access to the asbestos management plan. Regular communication about the risks and safety procedures helps maintain a high level of awareness and promotes a culture of safety. Safe removal and disposal Safe asbestos removal requires specialised techniques to prevent fiber dispersion, such as wetting materials and using appropriate containment and filtration systems. Qualified professionals must perform the removal, adhering to strict guidelines to ensure minimal exposure and prevent contamination of the surrounding environment. The disposal of asbestos materials must follow specific protocols to prevent environmental contamination and exposure risks. This includes sealing materials in labeled, leak-tight containers and transporting them to designated disposal sites. Compliance with legal disposal requirements is crucial for both environmental and public health. Protective equipment and tools Personal protective equipment (PPE) for handling asbestos includes respirators, protective clothing, gloves, and eye protection. These items are essential to prevent inhalation and skin contact with asbestos fibers. Selecting the appropriate PPE is critical for worker safety in environments where asbestos exposure is a risk. Selecting and maintaining the right tools for asbestos handling is crucial to prevent fiber release. Tools should be designed to minimise disturbance of ACMs, and regular maintenance ensures they remain effective. Vacuum cleaners with HEPA filters, for example, are essential for safe cleanup. Compliance with industry standards for safety gear ensures the effectiveness and reliability of PPE and tools used in asbestos handling. Regular inspections, adherence to maintenance schedules, and replacement of damaged equipment are key to maintaining compliance and ensuring worker safety. Regular monitoring and health surveillance Ongoing environmental monitoring in workplaces with asbestos is vital for detecting airborne fibers and assessing the effectiveness of control measures. Regular monitoring helps in identifying potential risks early and implementing corrective actions, thus ensuring a continuously safe work environment. Health surveillance programs for workers exposed to asbestos are essential for early detection of asbestos-related diseases. These programs typically include regular health check-ups, lung function tests, and providing health information to workers. Interpreting and acting on environmental and health monitoring data is crucial for effective asbestos management. This data helps in assessing the risk levels, the effectiveness of control measures, and the need for any changes in the management plan. Prompt action based on this data can prevent health hazards and ensure ongoing compliance. Conclusion Proactive safety measures in managing asbestos hazards are essential in industrial settings to protect worker health and comply with legal standards. Continuous education, effective risk management, and adherence to safety protocols are key components of a successful safety culture. Emphasizing the importance of these measures ensures a safer and more responsible industrial environment. AIMS' Note on Buying PPE and Workwear Hazard assessment: Identify the specific hazards you will likely be facing in your work environment. Consider potential risks such as chemical exposure, falling objects, loud noises, electrical hazards or biohazards. This assessment will guide you in selecting the appropriate PPE for the job. Appropriate materials: Different materials offer various protective qualities. Consider flame-resistant (FR) materials for fire hazards, chemical-resistant fabrics for handling hazardous liquids and high-visibility options for work in low-light environments. Compliance to occupational safety standards: Opt for PPE that meets the pertinent Australia Standard (AS), although some brands -- especially imports -- will have other compliance markings such as ANSI, OSHA, ANSI, NIOSH, oSA etc. Look for certifications on the product label to ensure the equipment has undergone rigorous testing. Proper fit and comfort: Proper fit is crucial for both comfort, dexterity and protection. Ill-fitting clothing can snag on machinery or restrict movement, potentially creating additional hazards. Choose sizes that allow for layering in cold weather without being overly bulky and consider adjustable options for items like hard hats or respirators. Maintenance and replacement: Inspect PPE before each use for signs of wear, tear or damage. Follow (and factor in) the manufacturer's instructions for cleaning and storage. Some materials may require specialised laundering, while others can be machine-washed. Check for durability to ensure the clothing can withstand frequent use and cleaning. Replace damaged or expired PPE immediately to guarantee your safety. Training: Ensure you and any employees understand how to properly use, wear, adjust, maintain and store PPE and workwear. Improper use can negate its protective benefits. This blog's sub-topics Cross-reference our Hard Hat Guide for hard hat colour meanings, classes and replacement intervals. People Also Ask — Asbestos Hazard Management Q: How do I identify asbestos-containing materials in an older building or plant? Asbestos-containing materials (ACMs) were widely used in Australian construction until 1987, when a partial ban was introduced, and fully banned in 2003. ACMs are commonly found in: flat cement sheeting (fibro), corrugated cement roofing, pipe lagging and insulation, floor tiles and backing, gaskets in older equipment and boilers, and some friction materials. Visual identification alone is not reliable — suspected ACMs must be sampled and tested by an accredited asbestos assessor (NATA-accredited laboratory). All workplaces built before 2003 should have an Asbestos Register under the WHS Regulations. Q: What are the legal obligations for managing asbestos in the workplace? Under the Model WHS Regulations and harmonised state/territory WHS laws, persons conducting a business or undertaking (PCBUs) must identify and manage asbestos hazards. Key obligations include: maintaining an Asbestos Register for pre-2004 buildings; developing an Asbestos Management Plan if ACMs are present; ensuring that any disturbance of ACMs is managed safely and, if friable or non-friable class A asbestos is being removed, performed by a licensed asbestos removalist; notifying SafeWork (or the state WHS regulator) of asbestos removal projects above certain quantities; and providing information and training to workers who may encounter ACMs. Q: What PPE is required for working near asbestos? The minimum PPE for working near undisturbed, sealed non-friable asbestos-containing materials (Class B removal) typically includes: a P2 half-face respirator (or higher, such as a P3 full-face respirator for friable or higher-risk work); disposable coveralls (Tyvek-style, AS/NZS 4501); and appropriate gloves. For Class A removal (friable asbestos), full-face air-purifying respirators with P3 HE cartridges or supplied-air respiratory protection are required. Contaminated disposable PPE must be bagged and disposed of as asbestos waste in compliance with state EPA requirements. Q: Can I remove asbestos myself as a business owner? In Australia, you can remove up to 10m² of bonded (non-friable) asbestos-containing material without a licence, but you must comply with the WHS Regulations requirements for non-licensed asbestos removal — including safe work practices, PPE, waste disposal, and notification obligations. Removal of more than 10m² of bonded asbestos, or any quantity of friable asbestos, must be carried out by a licensed asbestos removalist (Class B or Class A licence respectively). State-based WHS regulators provide guidance on the notification and clearance inspection requirements for licensed asbestos removal. Q: What is an asbestos clearance inspection and when is it required? A clearance inspection is a visual inspection and, where required, air monitoring conducted by an independent licensed asbestos assessor after asbestos removal to confirm the area is safe for re-occupation. Clearance inspections are required by the WHS Regulations after: any Class A (friable) asbestos removal; Class B (bonded) removal where there is a risk of fibre release during removal. The assessor must issue a clearance certificate before the area can be reoccupied. Independent assessment (the removalist cannot clear their own work) is a key requirement to ensure objectivity.
