The purpose of a safety lockout/tagout procedure is to ensure that machinery is completely shut down and cannot be restarted during maintenance or repair work. This critical safety measure is designed to protect workers from accidental machine startup, which could lead to severe injuries or fatalities.

By utilizing locks and tags, workers can securely isolate energy sources, preventing machinery from being inadvertently energized while maintenance activities are ongoing. This procedure emphasizes safety and creates a structured way to communicate that a machine is under maintenance, ensuring that all personnel are aware and can work safely around de-energized equipment.

In contrast, the other options address different aspects of machine operations that do not relate to safety during maintenance. Enhancing product quality, recording operational times, or designating machinery for specific tasks are important operational considerations but do not prioritize the critical safety functions that lockout/tagout procedures are specifically designed to address.
