Which NFPA standard governs automatic sprinkler systems?

• A. NFPA 13
• B. NFPA 10
• C. NFPA 101
• D. NFPA 25

Answer: (A)

NFPA 13, the Standard for the Installation of Sprinkler Systems, governs automatic sprinkler systems. It lays out how these systems must be designed and installed, including types of systems (wet, dry, deluge, etc.), sprinkler spacing, pipe sizing, materials, supports, water supply requirements, and hydraulic calculations. This standard ensures that an automatic sprinkler system is properly configured to function when needed. Other NFPA standards cover related topics that are not about installation: NFPA 10 addresses portable fire extinguishers, NFPA 101 is the Life Safety Code, and NFPA 25 covers inspection, testing, and maintenance of sprinkler systems.
