Shift Change Lockout
Shift Change Lockout is the set of formal procedures used to maintain continuous lockout/tagout protection during shift or personnel changes, ensuring an orderly transfer of control over energy-isolating devices between outgoing and incoming workers. It is required under WorkSafeBC OHS Regulation Part 10 and OSHA 29 CFR 1910.147(f)(4) to prevent hazardous energy release during servicing or maintenance.
On the shop floor, shift change lockout is implemented as a standardized procedure integrated into the lockout program and shift-handover practices. For individual lockout, the incoming worker applies their personal lock and tag before the outgoing worker removes theirs, ensuring no gap in protection. For group lockout involving multiple trades, a lockbox or multi-hasp system is used, with a trade/departmental lock bridging shifts. Incoming crew members sign in, verify isolation via try-start tests, and apply personal locks; outgoing members sign out only after incoming locks are in place. For non-congruent shifts, a maintenance lock may be applied by a supervisor to maintain continuity. Documentation, such as logs or SafeDesk records, captures lock transfer times, personnel, and hazards, ensuring clear accountability and compliance with WorkSafeBC and OSHA standards.
Under WorkSafeBC, can a supervisor remove a worker's lock at shift change if the worker has left the site?
Yes, but only under strict emergency-type conditions with formal steps: every reasonable effort must be made to contact the worker, the supervisor must ensure the equipment will operate safely, and the removal must be documented. In SafeDesk, this should be logged as a controlled override event with supervisor sign-off and automatic notification to the affected worker.
How should a group lockout spanning multiple shifts be structured to comply with WorkSafeBC Part 10?
Use a key-securing system (lockbox) with a trade/departmental lock to bridge shifts, plus individual worker locks. Maintain a group lockout record with equipment ID, isolation points, and worker signatures. At shift change, incoming workers sign in, verify isolation, and apply personal locks; outgoing workers sign out and remove locks only after incoming locks are applied. The trade/departmental lock remains until full release.
In a multi-shift operation, can a worker leave their lock on equipment overnight to maintain protection?
Yes, with conditions: the worker must log activities, notify the Lockout Coordinator, and document that the lock is intentionally left and equipment must not be operated. SafeDesk can support a 'Lock left in place' status tied to the worker's ID and planned return time, preventing restart until formal release.
