Which statement is not typically included on an arc flash warning label after a hazard analysis?

• A. Hazard risk category
• B. Shock-hazard boundary distances
• C. Required PPE
• D. Calibration date of tools

Answer: (D)

Arc flash warning labels are designed to convey the protective measures needed for working on or near energized equipment. They typically include information that helps a worker choose the right level of protection and know how close they can approach the live parts: the hazard risk category or PPE category shows the required level of flame-resistant gear, the shock-hazard boundary distances indicate how far to stay away to avoid shock, and the specific PPE items to wear are listed so the worker can correct gear without delay. The calibration date of tools, while important for ensuring measurement accuracy, doesn’t reflect the energy hazard or PPE needs of the equipment being serviced, so it isn’t part of the arc flash label. In practice, the label focuses on the incident energy or PPE category, boundaries, voltage, and required protective gear, not maintenance tool calibration dates.
