Usually, these tags have a grommet near the top so they can be easily attached to locks, hasps, machines, switches, and more. One tag will suffice per machine, but if multiple employees are working on the same machine, they can use their personal safety lock with their own tag attached.
Why are tags used in lockout tagout?
Facilities use lockout tagout tags to convey important information and let employees know that hazardous machines are currently being repaired or serviced. The tags inform and warn employees that the machines to which they are attached cannot be switched on or operated until the tags have been removed.
