NFPA 409 covers which facility?

NFPA 409 covers which facility?

• A. Standard for Water-Cooling Towers
• B. Standard on Water Mist Fire Protection Systems
• C. Standard on Aircraft Hangars
• D. Standard for Marine Terminals, Piers, and Wharves

Answer: (C)

NFPA 409 is the standard that covers aircraft hangars. These facilities have unique fire hazards, including large open spaces, substantial aircraft fuel loads, and the need to protect both the structures and the aircraft themselves. The standard specifies fire protection measures tailored to hangars, such as appropriate suppression and detection systems, fire barriers, and considerations for hangar construction and ventilation. The other topics refer to standards for different facilities or technologies—water-cooling towers, water mist systems, and marine terminals—each governed by separate NFPA documents. They don’t apply to aircraft hangar fire protection, so the aircraft hangar standard is the correct one.
