When can you remove a lock with a "do not remove" tag from electrical equipment?

The correct choice highlights the fundamental principle of safety in lockout/tagout (LOTO) procedures, which are critical in the maintenance and operation of electrical equipment. A "do not remove" tag signifies that a piece of equipment is not safe to operate, usually because maintenance work is being conducted or there are hazards present.

Only the individual who installed the lock and tag is authorized to remove it, as they are aware of the specific work conditions or risks associated with that equipment. This ensures that safety protocols are adhered to, preventing accidents or injuries resulting from unauthorized removal. The person who placed the tag can assess whether it is safe to remove it based on their understanding of the work completed.

Other options don't adhere to safety procedures. For example, removing the lock simply because the equipment is needed disregards the potential hazards and can lead to dangerous situations. Similarly, allowing a co-worker to instruct the removal without having the necessary insight or authorization undermines the safety protocols in place.
