How does NFPA 2001 handle maintenance of agent cylinders and piping?

• A. Regular inspection and service of cylinders, valves, piping, and fittings, including replacement or recharge as needed
• B. No maintenance required unless a leak occurs
• C. Only cylinders require service
• D. Maintenance is optional

Answer: (A)

Regular inspection and service of all parts of the agent delivery system is required, including cylinders, valves, piping, and fittings, with replacement or recharge of the agent as needed. This ensures the system stays ready to discharge at the proper concentration and pressure, and it helps catch leaks, corrosion, damaged connections, or degraded components before a discharge occurs. It also covers keeping seals and fittings in good condition and confirming that the system remains compliant with the standard through appropriate periodic checks and servicing. Maintenance isn’t optional or limited to one component; every part of the delivery network is maintained to preserve reliability and performance.
