Lockout-tagout (LO/TO) safety procedures, as defined by Occupational Safety and Health Administration (OSHA), require that lockout devices be durable and standardized. Lockout devices use color, warning labels or tags, and a physical barrier to temporarily prohibit machine operation or power activation, and reduce accidents, during maintenance or repair. This padlock is just one of many parts needed to safely execute a lockout.
