SafetyQuestion 667 of 700
During lockout/tagout (LOTO) on a jobsite, several workers each apply their own personal lock to an energy-isolating device. Who is authorized to remove a given worker's lock?
a.Any supervisor who wants the equipment back in service
b.The first worker who finishes the task
c.Any qualified electrician on site
d.Only the individual worker who applied that lock (with narrow exceptions under a documented procedure)
Explanation
Correct: under LOTO, each worker's personal lock may be removed only by that same worker, ensuring no one is re-energizing equipment while another is still exposed. Narrow exceptions exist when that worker is unavailable, but only through a documented procedure with verification. Letting a supervisor, the first-finished worker, or any electrician remove another's lock defeats the whole protection.
