Which NFPA standard covers the maintenance of automatic sprinklers?

• A. NFPA 25
• B. NFPA 13
• C. NFPA 72
• D. NFPA 101

Answer: (A)

The main idea is that maintenance and ongoing care of sprinkler systems are governed by a standard that focuses specifically on keeping water-based systems operational after installation. NFPA 25 is the standard for inspection, testing, and maintenance of automatic sprinklers and other components of water-based fire protection systems. It describes what to check during routine maintenance, how often to perform tests, and how to document findings, all with the goal of ensuring the system will function when needed.

In contrast, NFPA 13 covers how sprinkler systems should be designed and installed, including layout and pipe sizing; NFPA 72 covers fire alarm and signaling systems; and NFPA 101 addresses life safety requirements in buildings. Because maintenance of installed sprinklers is about keeping an already-installed system reliable, NFPA 25 is the correct reference.
