If a Flash Hazard Label is present on the MCC, how should PPE be determined?

• A. Apply standard PPE regardless of label
• B. Follow the category PPE on the label
• C. PPE is not required if label exists
• D. Use Table Method only

Answer: (B)

When a Flash Hazard Label is on an MCC, you determine your PPE from the category shown on that label. The label translates the device’s arc-flash energy at that location into a specific PPE category, detailing the minimum protection you must wear for that equipment. This ensures your protection matches the actual hazard you’d face if a fault occurred, since the label reflects the device-specific energy level.

The Table Method is a general way to estimate PPE when a label isn’t available or as a planning aid, but it isn’t the controlling approach when a label exists. The label’s category takes precedence because it directly represents the hazard present on that particular piece of equipment. So, if the label requires a certain category of PPE, you wear gear that meets that category, rather than assuming standard PPE or skipping protection. For example, a Category 2 designation on the label means you must wear PPE appropriate for Category 2, including the specified arc-rated clothing and face protection, plus any required gloves and accessories.
