What is the primary means by which an electrical maintenance worker is protected from electrical hazards while performing work on an electrical circuit?
AI Explanation
The correct answer is D) performing a lockout/tagout procedure.
Lockout/tagout is the primary means by which an electrical maintenance worker is protected from electrical hazards while performing work on an electrical circuit. This is because lockout/tagout ensures that the circuit is de-energized and cannot be accidentally re-energized during the maintenance work, eliminating the risk of electrical shock or injury. The other options, while important safety measures, do not provide the same level of protection as a full lockout/tagout procedure.
