Maintenance of fire-extinguishing systems and listed exhaust hoods must be performed by what kind of personnel?

• A. Properly trained, qualified, and certified personnel acceptable to the Authority Having Jurisdiction
• B. Licensed firefighters only
• C. On-site staff
• D. Volunteers

Answer: (A)

Maintenance must be performed by properly trained, qualified, and certified personnel acceptable to the Authority Having Jurisdiction. This ensures technicians have demonstrated competency with the specific fire-extinguishing systems and listed exhaust hoods, follow the correct testing and service procedures, and comply with applicable NFPA standards and local codes. The AHJ’s acceptance guarantees that the individuals performing the work meet the required level of expertise and accountability, reducing the risk of improper maintenance, system failure, or accidental discharge. While licensed firefighters, on-site staff, or volunteers may have valuable experience, they may not always hold the specialized training, certifications, or formal approval needed to service these systems to code and safety standards.
