NFPA Standard used for design of clean agent extinguishing systems is NFPA ______.

• A. 2001
• B. 101
• C. 1962
• D. 13

Answer: (A)

Clean agent extinguishing system design is governed by NFPA 2001, the Standard for Clean Agent Fire Extinguishing Systems. This standard lays out the requirements for selecting the agent, determining the required design concentration for effective extinguishment, and designing the system components such as room volume considerations, piping, discharge helmets/nozzles, and integration with detection and alarm systems. It also covers commissioning, testing, and ongoing maintenance to ensure the system operates correctly when needed. The other standards address different topics: NFPA 101 deals with life safety code and occupant protection, NFPA 13 covers water-based sprinkler systems, and NFPA 1962 relates to portable extinguishers and related maintenance.
