Which NFPA standard focuses on the testing and maintenance of water-based fire protection systems?

The focus of NFPA 25 is specifically on the testing, inspection, and maintenance of water-based fire protection systems, such as sprinkler systems and standpipe systems. This standard provides detailed guidelines and procedures to ensure that these systems function correctly and reliably when needed. Regular testing and maintenance are crucial for maintaining the integrity of the fire protection systems to safeguard life and property during a fire emergency.

Other options represent different aspects of fire safety and codes. NFPA 13 deals with the installation of sprinkler systems, NFPA 72 outlines the National Fire Alarm and Signaling Code, and NFPA 101 is known as the Life Safety Code, which focuses on building egress and life safety requirements. While these standards are important for fire safety, they do not cover the testing and maintenance of water-based fire protection systems, making NFPA 25 the appropriate choice for this particular focus.
