NFPA 25 is a standard that sets minimum requirements for the periodic inspection, testing, and maintenance of water-based fire protection systems. The standard covers a wide range of systems, including sprinkler systems, standpipe and hose systems, fire pumps, water storage tanks, water spray fixed systems, foam-water sprinkler systems, and water mist systems. NFPA 25 also addresses how to evaluate and address changes that occur to a building, its use, or water supply that could potentially impact the performance of water-based fire protection systems. The standard includes definitions of key terms, inspection and testing procedures, and requirements for corrective action when deficiencies or impairments are found. It also provides guidance on the roles and responsibilities of various stakeholders involved in the inspection, testing, and maintenance process, including property owners, inspectors, contractors, and authorities having jurisdiction.
