• A. An arc flash risk assessment must be completed
• B. Use appropriate personal protective equipment
• C. Power down all equipment immediately
• D. Install additional lighting in the area

Answer: (A)

If arc flash hazards are present, an arc flash risk assessment must be completed to ensure the safety of personnel working with or near the electrical equipment. This assessment is critical as it identifies the potential hazards associated with arc flash incidents, evaluates the risk severity, and determines the appropriate safety measures to implement. The assessment considers factors like the working environment, equipment ratings, and the necessary protective gear for personnel.

Conducting a proper arc flash risk assessment allows for informed decisions regarding safety protocols and the selection of appropriate personal protective equipment. It also provides guidelines on how to safely perform tasks around energized electrical equipment. Therefore, this process is foundational in establishing a comprehensive safety plan to mitigate the risks associated with arc flash hazards.
