Lockout/Tagout (OSHA 1910.147) protects workers from the unexpected release of hazardous energy during service and maintenance. Work this checklist for the authorized-employee procedure — missing any step is a common cause of serious machinery injuries.
Lockout / tagout equipment
FAQ
One lock per person?
Yes. Each authorized employee applies their own uniquely keyed lock and tag, and only that person removes it. Group lockout uses a hasp so every worker’s lock must come off before energization.
Is a tag alone enough?
No. A tag is a warning, not a physical restraint. Where an energy-isolating device can accept a lock, it must be locked out; tagout-only is allowed only when lockout is not possible and with additional safeguards.
Educational summary of OSHA 29 CFR 1910.147. It does not replace a written, machine-specific energy-control procedure, authorized-employee training, or periodic inspections.
