What is the purpose of a lockout/tagout procedure?

The purpose of a lockout/tagout (LOTO) procedure is to ensure that equipment is properly shut off and cannot be started again until maintenance or servicing is fully complete. This safety protocol is critical in industrial and maintenance settings, as it helps prevent accidental machine start-up while workers are performing repairs or maintenance, thereby reducing the risk of injury or even fatal accidents. The application of lockout/tagout procedures ensures that energy sources are effectively controlled and that workers are protected from unexpected re-energization of equipment.

This procedure is implemented through specific steps which include identifying all energy sources, isolating those sources, and then locking them out using locks and tags to indicate that the equipment must remain de-energized. This reinforces personal accountability and serves as a warning to others that maintenance work is in progress. The effectiveness of LOTO procedures hinges on adherence to safety practices and protocols, significantly contributing to workplace safety.
