When multiple workers or trades are working on the same energized system, a group Lockout/Tagout (LOTO) procedure is required to ensure no one is left unprotected.
Why It Matters:
If just one person has the authority to remove a lock on shared equipment, others may be exposed to hazardous energy without warning. OSHA requires each individual to be personally protected when working on de-energized electrical systems (1910.333 & 1926.417). Group LOTO ensures every worker stays safe until all work is complete.
Key Points:
- Use a group lockbox system or multi-lock hasp at the disconnect point.
- The lead authorized employee applies the primary lock and places the keys in a secure lockbox.
- Each crew member applies their personal lock to the group lockbox. The equipment cannot be energized until every individual has removed their lock.
- Clearly identify the lead responsible for overseeing LOTO and coordinating with all parties.
- Review the LOTO procedure as a team before starting any work.
✅ One system, multiple locks — full protection for every worker.
Ask the Crew:
- Are we using a group lockbox or hasp for shared electrical work?
- Does everyone understand when and how to apply their own lock?
- Who is the lead person coordinating this group LOTO?
