Secure a single breaker switch with multiple padlocks to keep electricity safely off until the entire team is finished with a maintenance task. The key that unlocks these lockouts is at the end of a 2-ft. cable—wind it through the lock mount and secure by adding a padlock for each person working. The key is released only when all padlocks are removed.

Less disruptive than locking access to an entire panel, these lockouts isolate a single circuit. Because they're small and don't hold the padlocks, you'll still have room in your breaker box to flip adjacent switches on and off or close the panel door. These lockouts help your organization comply with OSHA 29 CFR 1910.147, which requires electrical circuits to be locked out during maintenance to prevent injuries.

Clamp-on lockouts can be installed on switches with or without through holes, since they clamp onto the surface of the switch.
