Which of the following must be included on Lock-out Devices?

The inclusion of the identity of the employee applying the lock-out device is essential for several important reasons. First and foremost, it ensures accountability. If an incident occurs or if equipment needs to be accessed, having the identity clearly marked allows for easy communication and coordination. It helps to prevent unauthorized removal of the lock and ensures that the individual responsible for the lock-out can be quickly identified for clarification on the status of the equipment. This procedure is a fundamental safety measure in lock-out/tag-out protocols, which are designed to prevent accidental energization or release of hazardous energy.

Other options, while they may contain relevant information regarding the lock-out device, do not convey the same level of critical identification and accountability requirement as the identity of the employee. Understanding this critical aspect can enhance workplace safety and compliance with regulations governing the use of lock-out/tag-out devices.
