OSHA’s LOTO standard (29 CFR 1910.147) requires three groups of employees when training for lockout tagout:
Authorized employees – as a general rule, this group includes electricians, maintenance workers, and specific machine operators. OSHA only permits this group to perform LOTO.
Affected employees – this group includes those who work with machines but are not permitted to conduct LOTO.
Other employees – this group consists of anyone else who works around a machine or equipment where LOTO procedures are used.
