Copy Citation
Lockout-tagout (LOTO) or lock and tag is a safety procedure which is used in industry and research settings to ensure that dangerous machines are properly shut off and not able to be started up again prior to the completion of maintenance or repair work. It requires that hazardous energy sources be "isolated and rendered inoperative" before work is started on the equipment in question. The isolated power sources are then locked and a tag is placed on the lock identifying the worker who placed it. The worker then holds the key for the lock ensuring that only he or she can remove the lock and start the machine. This prevents accidental startup of a machine while it is in a hazardous state or while a worker is in direct contact with it. Lockout-tagout is used across industries as a safe method of working on hazardous equipment and is mandated by law in some countries.

- The standard provides a limited exception to the requirement that energy control procedures be documented. If an employer can demonstrate the existence of each of the eight elements listed in 29 CFR 1910.147(c)(4)(i), the employer is not required to document the energy control procedure. However, the exception terminates if circumstances change and any of the elements no longer exist
