The product range includes safety padlocks, electrical and valve lockout devices, group lockout solutions, lockout kits, stations, and identification products, supporting structured energy-isolation procedures across industrial workplaces.

Safety Padlocks

The range includes thermoplastic, aluminium, and laminated steel options, with different colours, shackle configurations, and keying systems to support personnel identification and facility-specific LOTO requirements.

Lockout Devices

Master Lock provides lockout devices for isolating different hazardous energy sources, including electrical and valve lockout applications. These devices are used with safety padlocks to help prevent equipment from being re-energized while maintenance or servicing work is being performed.

Group Lockout Solutions

For maintenance activities involving multiple authorized employees, Master Lock offers group lockout equipment that supports controlled energy isolation while allowing individual workers to maintain personal control within the lockout procedure.

Lockout Kits and Stations

Portable LOTO kits and lockout stations organize safety padlocks and lockout devices so that required equipment is readily available at the workplace. Master Lock offers configurations for electrical, valve, and combined lockout applications.

Practical Applications

Master Lock Lockout-Tagout products can be used during machine maintenance, electrical servicing, equipment repair, cleaning, inspection, and other activities requiring hazardous energy isolation. The broad range allows LOTO equipment to be selected according to the energy source, isolation point, number of employees involved, and facility-specific energy-control procedure.
