Attaching the authorized employee’s picture to the lockout/tagout tag is one of the most convenient ways to help identify who is in charge of the lockout of certain equipment. However, this does not have to be the case all of the time. In some cases, having the authorized person's name on the LOTO tag is enough to communicate who performed the lockout.
Either way, LOTO tags need to be compliant with OSHA 1910.147(c)(7)(ii)(C) – tags must be legible and understandable by all authorized employees, affected employees, and all other employees whose work operations are or may be in the area, in order to be effective.
