All electrical parts exceeding 50 volts will be de-energized before an employee works on or near equipment.

• A. False
• B. Depends on the situation
• C. Only with supervisor approval
• D. True

Answer: (D)

The main idea is to minimize exposure to electrical hazards by removing energy before work. Any part that can deliver an electrical shock or cause an arc flash is much safer to handle when it is de-energized. The 50-volt threshold is a practical cutoff used in safety guidance because voltages above this level pose a real risk of shock and arc energy to a person.

So the standard practice is to de-energize electrical parts that exceed 50 volts before an employee works on or near the equipment. This is reinforced by lockout/tagout and verification steps to ensure there is no residual energy. Only in rare cases where de-energizing would create an unacceptable risk or disrupt essential operations would workers proceed with additional protective controls after careful assessment. But as a general rule, de-energizing is the expected approach, making the statement true.
