NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, 2020 Edition

ABOUT THE BOOK

NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, 2020 Edition is an authoritative technical publication developed by the National Fire Protection Association (NFPA). It establishes minimum requirements and procedures for inspecting, testing, and maintaining water-based fire protection systems to help ensure their reliability, operational readiness, and effectiveness during fire emergencies.

The standard is organized into 16 chapters covering the essential requirements for maintaining different types of fire protection installations. It begins with general administration, definitions, responsibilities of property owners, recordkeeping, inspection procedures, testing requirements, maintenance practices, and safety considerations. The subsequent chapters address sprinkler systems, standpipe and hose systems, private fire service mains, fire pumps, water storage tanks, fixed water spray systems, foam-water sprinkler systems, and water mist systems.

Additional coverage focuses on common system components and valves, internal piping condition, obstruction investigations, and procedures for managing system impairments. It explains how professionals should identify deficiencies, evaluate system performance, maintain equipment, and restore impaired systems to proper working condition. The standard also addresses situations where changes in building occupancy, usage, processes, materials, hazards, or water supplies may affect the performance of existing fire protection systems.

A significant feature of this edition is its detailed inspection, testing, and maintenance frequency guidance. Requirements cover activities performed at different intervals, including daily, weekly, monthly, quarterly, semiannual, annual, and five-year inspections or tests, depending on the system and component. This structured approach helps facility managers and maintenance professionals establish effective schedules and maintain appropriate records.

The publication also includes informative annexes and practical supplementary resources, such as inspection and testing forms, reporting guidance, fire pump troubleshooting information, obstruction investigation procedures, hazard evaluation forms, connectivity and data collection guidance, and color-coded tagging programs. These resources support the practical implementation of the standard in real-world facilities.

Designed for fire protection engineers, inspectors, contractors, building owners, facility managers, maintenance technicians, and safety professionals, NFPA 25, 2020 Edition is an important reference for fire protection system maintenance, regulatory compliance, technical training, and life-safety management. It provides the guidance needed to help keep water-based fire protection systems dependable and ready to perform when they are needed most.
