If a complete electrical hazard analysis has been performed, an arc flash and shock hazard warning label will provide ___.

• A. The hazard risk category
• B. Shock-hazard-approach-boundary distances
• C. Required PPE
• D. All of these

Answer: (D)

Labels on equipment after a complete hazard analysis communicate all the safety details you need to work safely. The arc flash portion of the label shows how severe the arc flash risk is, which is captured by the hazard risk category (the PPE level you must wear). It also specifies the arc flash boundary, telling you how far you must stay away from energized parts to avoid arc exposure, and it identifies the PPE required to operate within that zone. For shock hazards, the label provides the shock-hazard boundary distances, so you know the approach limits to prevent contact with live parts. Since a thorough hazard analysis yields both the arc flash information (severity and PPE) and the shock boundary information, the label ends up listing all of these safety requirements. That’s why the best answer is that it provides the hazard risk category, the shock-hazard approach-boundary distances, and the required PPE.
