What does the term "locking out/tagging out" refer to?

The term "locking out/tagging out" refers to a safety procedure developed to protect workers from the accidental re-energization of equipment during maintenance or repair tasks. This process involves placing a lock on the energy isolating device of the equipment to prevent it from being turned back on while workers are still in the area. Additionally, a tag is affixed alongside the lock to provide clear communication that the equipment must not be operated until the lock is removed by the authorized individual who placed it.

This procedure is essential in ensuring that workers are not exposed to hazards that could arise from unexpected energization or the activation of machinery. By effectively using locks and tags, companies can maintain a safer work environment, foster adherence to safety regulations, and minimize the risk of accidents, injuries, or fatalities.
