In arc flash hazard analysis, who is typically responsible for identifying hazards and implementing control measures?

• A. Qualified person
• B. Untrained worker
• C. Manager outside the electrical team
• D. Administrative staff

Answer: (A)

The main concept here is who has the training and authority to spot arc flash hazards and put safeguards in place. A qualified person is recognized as someone with the knowledge and skills to assess electrical risks, perform arc flash hazard analyses, determine incident energy, select appropriate PPE, and implement the necessary protective controls and work practices. This includes evaluating the electrical system, deciding on engineering and administrative controls, and ensuring that PPE is properly used before any energized work. An untrained worker typically lacks the expertise to identify hazards and choose protections, while a manager outside the electrical team or administrative staff generally does not have the technical qualifications to perform these analyses and implement controls. So the responsible party is the qualified person who has the appropriate training and authority.
