What document provides incident energy and PPE requirements for arc flash hazards?

• A. The electrical code.
• B. The safety manual for the site.
• C. Arc flash labels provide incident energy and PPE requirements.
• D. The manufacturer's warranty sheet.

Answer: (C)

Arc flash labels on electrical equipment carry the exact incident energy value and the PPE needed for that device. After an arc flash study, the label specifies the incident energy in cal/cm² and the minimum PPE, sometimes with the arc flash boundary. This makes the label the direct reference workers use to determine the appropriate gear for that specific equipment, rather than relying on general codes or manuals. The electrical code provides broad safety requirements but not device-specific energy numbers. A site safety manual may outline procedures but isn’t tied to the exact energy for each piece of equipment. The manufacturer's warranty sheet has no relevance to arc flash PPE or incident energy.
