What is a 'lockout/tagout' procedure?

A 'lockout/tagout' procedure is a critical safety protocol used in various industries to ensure that machines and equipment are properly shut down and cannot be restarted until maintenance or repair work is completed. This process typically involves physically locking the energy-isolating devices and tagging them to indicate that the equipment is not to be operated.

This procedure is crucial because it prevents unexpected energization or start-up of machinery that could lead to serious injuries or fatalities during maintenance work. By ensuring that all sources of energy are controlled and that equipment remains in a safe state, workers can perform their tasks without the fear of accidental operation of the equipment.

The other choices do not correctly describe the scope and intent of lockout/tagout procedures. While securing tools and equipment might involve some safety measures, it does not encompass the specific requirement of ensuring machinery cannot be restarted. Monitoring worker attendance and electrical insulation techniques are unrelated to the lockout/tagout process, which is solely focused on the safety of personnel working on equipment.
