Lockout: In practice, lockout is the isolation of energy from the system (a machine, equipment, or process) which physically locks the system in a safe mode. Tagout: Tag out is a labelling process that is always used when lockout is required. The process of tagging out a system involves attaching or using an indicator (usually a standardized label) that includes the following information: • Why the lockout/tag out is required (repair, maintenance, etc.). • Time of application of the lock/tag. • The name of the authorized person who attached the tag and lock to the system.
Lockout/Tagout refers to the procedures established for Control of Hazardous Energy, as described by the Occupational Safety and Health Administration (OSHA) under Federal Registry 29 CFR 1910.147.
