What action must an authorized employee take regarding the energy-isolating device?

An authorized employee must lock or tag the energy-isolating device to ensure that it is safely maintained and prevented from being accidentally activated while maintenance is being performed. Locking or tagging the device is an essential component of the Lockout/Tagout (LOTO) procedure, which is designed to protect employees from unexpected energization or startup of machinery during maintenance activities. This action provides a visible indication that the equipment is not to be used, reducing the risk of injury.

By locking the device, the employee ensures that only they, or individuals who are aware of the lockout procedure, can remove it, helping to enforce safety protocols. Tagging adds an additional layer of safety by providing clear communication that work is being conducted on the equipment, thereby alerting others to the potential hazards.
