An electrical panel is being serviced using lockout/tagout procedures. Who is authorized to remove the lockout device?
Correct Answer
A) The specific worker who applied the lock
OSHA's lockout/tagout standard requires that only the employee who applied the lockout device can remove it. This ensures the worker who locked out the energy source controls when it is re-energized.
Why This Is the Correct Answer
OSHA's Control of Hazardous Energy (Lockout/Tagout) standard 29 CFR 1910.147 specifically states that lockout devices must be removed only by the employee who applied them. This personal responsibility ensures that the worker who locked out the energy source maintains complete control over when the equipment is re-energized. The rule protects the worker by preventing others from inadvertently removing the lockout while the original worker may still be exposed to hazardous energy. This is a fundamental safety principle that cannot be delegated to supervisors, other workers, or safety personnel.
Why the Other Options Are Wrong
Option C: The safety officer
While supervisors may authorize the work and oversee lockout/tagout procedures, they cannot remove another employee's lockout device. OSHA regulations specifically prohibit anyone other than the employee who applied the lock from removing it, regardless of their authority level.
Option D: The supervisor who authorized the work
Even qualified electricians cannot remove lockout devices applied by other workers. The OSHA standard makes no exceptions based on qualifications or expertise - only the person who applied the specific lockout device has the authority to remove it.
Memory Technique
Think 'My Lock, My Life, My Responsibility' - the person whose safety depends on the lockout is the only one who should control when it's removed.
Reference Hint
OSHA 29 CFR 1910.147 - The Control of Hazardous Energy (Lockout/Tagout) standard, specifically section 1910.147(e)(3) regarding lockout device removal
