Master Lock Safety Padlocks — LOTO Compliant Isolation Locks
Master Lock safety padlocks are the foundation of any LOTO programme. The thermoplastic body range is available in multiple colours to support colour-coded isolation procedures across trades, shifts and departments — a critical requirement in mining, petrochemical and heavy manufacturing environments. Padlocks are available keyed alike (for master-keyed systems), keyed different (one person, one key) or in bulk sets for site-wide rollouts. AIMS Industrial also offers in-house laser engraving on safety padlocks for permanent personalisation.

Master Lock LOTO Devices, Stations & Kits
Beyond the padlock, a compliant LOTO programme requires the right isolation devices for every energy source on site. Master Lock's LOTO device range covers circuit breakers, ball valves, gate valves, butterfly valves, pneumatic lines, electrical plugs and more — ensuring every energy source can be physically locked out before maintenance begins. Complete lockout stations and personal lockout kits make it straightforward to build out a full programme from scratch, with all required devices, hasps and tags supplied together.
