What is the purpose of a lock-out/tag-out procedure?

The purpose of a lock-out/tag-out procedure is primarily to ensure that equipment is safely deactivated before maintenance work begins. This procedure involves placing a lock and a tag on a piece of equipment to prevent it from being accidentally energized while maintenance is being performed. By doing this, technicians and workers can carry out their tasks without the risk of electric shock, injury, or damage to the equipment caused by unintended activation.

This practice is critical in environments where multiple workers may be operating different equipment, as it establishes a clear protocol for safety. It assures that once maintenance personnel have locked and tagged the machinery, no one else can inadvertently turn it back on until it is safe to do so. This not only protects the workers but also ensures compliance with safety regulations and industry standards, making it an integral part of electrical and mechanical safety training in various industries, including entertainment.
