What is the purpose of Lockout/Tagout (LOTO) procedures in a maintenance shop?

• A. To prevent unexpected energization or startup of equipment while it is being serviced.
• B. To document maintenance schedules
• C. To secure tools
• D. To train employees

Answer: (A)

Lockout/Tagout procedures exist to prevent unexpected energization or startup of equipment while it is being serviced. By isolating all energy sources, applying a lock to the energy-control device, and tagging the equipment to warn others, the machine cannot be turned back on until the lock is removed by the person who applied it and it’s verified safe. This protects workers from severe injuries or death that could occur if a machine were to energize during maintenance. While documenting maintenance schedules, securing tools, and training employees are important parts of broader safety programs, the primary purpose of LOTO is to stop unexpected energization during servicing.
