An electrical panel is being serviced and requires lockout/tagout. Who is authorized to remove the lockout device?
Correct Answer
A) Only the worker who installed the lock
OSHA lockout/tagout procedures require that only the worker who applied the lockout device may remove it, ensuring personal protection and preventing unauthorized energizing.
Why This Is the Correct Answer
OSHA's Control of Hazardous Energy (Lockout/Tagout) standard 29 CFR 1910.147 explicitly requires that only the authorized employee who applied the lockout or tagout device may remove it. This fundamental rule ensures personal protection by preventing others from inadvertently energizing equipment while the original worker may still be exposed to hazards. The person who locked out the equipment is the only one who knows their work status and safety position.
Why the Other Options Are Wrong
Option B: Any qualified electrician
While qualified electricians have technical expertise, OSHA LOTO standards don't authorize any electrician to remove another worker's lockout device. Only the specific worker who applied the lock can remove it, regardless of others' qualifications or expertise.
Option D: The job site supervisor
Safety officers enforce safety protocols but cannot remove individual workers' lockout devices. The LOTO standard specifically requires that only the worker who applied the lock may remove it, with very limited exceptions for specific circumstances involving proper procedures and verification.
Memory Technique
Remember 'My Lock, My Life' - only the person whose life depends on that specific lockout can remove it. The worker who locks it is the only one who unlocks it.
