What term describes a study used to assess a worker's potential exposure to arc flash energy?

• A. Arc flash risk assessment
• B. Safety training
• C. PPE inventory
• D. Incident report

Answer: (A)

Arc flash risk assessment is the study used to estimate potential exposure to arc flash energy. It analyzes electrical system information, fault current, system voltage, protective device coordination, and working conditions to calculate incident energy levels and the arc flash boundary, which then guide the required PPE and safety controls. This is distinct from safety training, PPE inventory, or an incident report, which are education, equipment stock, or event documentation—not a proactive assessment of exposure risk.
