Lockout/Tagout
safetyLockout/tagout (LOTO) is a safety procedure used to ensure that electrical equipment is properly shut off and cannot be accidentally re-energized while maintenance or repair work is being performed. The process involves turning off the power source, physically locking the disconnect or breaker in the off position, and attaching a tag identifying who locked it out and why. This procedure is a cornerstone of electrical workplace safety.
