Help ensure the integrity of critical water-based fire protection systems with the latest edition of NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, 2023 edition. Properly functioning fire sprinklers can significantly reduce the extent of property damage and increase the chance of building occupants escaping a fire. However, keeping these systems in optimal condition calls for a thorough understanding of complex mechanics, equipment, and practices. NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, is incorporated by reference in many US states and offers comprehensive requirements for helping to ensure that these fire protection systems are ready to respond in the event of an emergency. The updated and expanded NFPA 25, 2023 edition, is the most current and complete document covering inspection, testing, and maintenance of water-based fire protection systems. NFPA 25 is the industry benchmark for ITM, including fire pump operation and flow tests, evaluation techniques such as sprinkler inspections, valve status tests, internal piping assessments, and forward flow tests for backflow preventers. From risk assessments and preparing preplanned impairment reports to performance-based testing programs and hydrant flushing and testing, you get expert-developed content reflecting the most current standards and technologies. Significant changes and additions to NFPA 25 include: New ITM requirements for dry systems where nitrogen is used and requirements for antifreeze systems Added Annex H to provide guidance related to legacy antifreeze systems and the hazards associated with them Added requirements for accessibility and air vents Additional requirements to remove concealed sprinkler cover plates and inspect a representative sample of sprinklers every five years Modifications of the first test requirement for fast-response sprinklers except control mode specific application (CMSA) and early suppression fast-response sprinklers (ESFR) from 20 years to 25 years Minimize hazards and help protect lives and property by complying with the latest standard. The importance of NFPA 25 to sprinkler system effectiveness cannot be overstated—NFPA 13, Standard for the Installation of Sprinkler Systems, requires that installers leave a copy of NFPA 25 with property owners. Get the quintessential resource for helping building owners, facility managers, inspectors, and service providers collaborate to improve fire suppression in commercial and residential installations
