For energized tasks on equipment rated greater than 240 volts up to 600 volts, arc flash PPE is required.

• A. True
• B. False
• C. Only for voltages above 1000 V
• D. Only for lab work

Answer: (A)

Arc flash PPE is required for energized work on equipment rated greater than 240 V up to 600 V because arc faults can unleash dangerous thermal energy at these voltages. The standard approach is to perform a hazard analysis to determine the incident energy and then select PPE that is arc-rated for that energy level. In practice, this means wearing flame-resistant clothing, an arc-rated face shield or hood, and arc-rated gloves suitable for the anticipated energy, with additional PPE as needed based on the specific conditions. The requirement isn’t about voltages above 1000 V or about lab work alone; it applies to energized tasks within the 240–600 V range in general settings.
