OSHA 29 CFR 1910.303 through 1910.335 cover safety in the general industry. OSHA 29 CFR 1910.333 addresses work practices for electrical equipment specifically. OSHA 29 CFR 1910.147 covers energy control, which ties directly into lockout-related electrical safety signs. OSHA 29 CFR 1910.145 covers accident-prevention signs and tags.

Following ANSI Z535 formatting is widely used. The sign is accepted as meeting OSHA requirements. The standardized color coding and signal word system mean workers can read and process the sign faster, which is worth more than a custom design that takes a few seconds to interpret.
