NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems
NFPA 25 水系灭火系统检测、试验、维护标准
1.1* Scope. This document establishes the minimum requirements for the periodic inspection, testing, and maintenance of water-based fire protection systems, including land-based and marine applications.
1.1.1 This standard does not address all of the inspection, testing, and maintenance of the electrical components of the automatic fire detection equipment for preaction and deluge systems that are addressed by NFPA 72, National Fire Alarm Code. The inspection, testing, and maintenance required by this standard and NFPA 72, National Fire Alarm Code, shall be coordinated so that the system operates as intended.
1.1.2 The types of systems addressed by this standard include, but are not limited to, sprinkler, standpipe and hose, fixed water spray, and foam water. Included are the water supplies that are part of these systems, such as private fire service mains and appurtenances, fire pumps and water storage tanks, and valves that control system flow. The document also addresses impairment handling and reporting. This standard applies to fire protection systems that have been properly installed in accordance with generally accepted practices. Where a system has not been installed in accordance with generally accepted practices, the corrective action is beyond the scope of this standard. The corrective action to ensure that the system performs in a satisfactory manner shall be in accordance with the appropriate installation standard.
1.1.3 This standard shall not apply to sprinkler systems designed and installed in accordance with NFPA 13D, Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes.
A.1.1 Generally accepted NFPA installation practices for water-based fire protection systems relevant to this standard are found in the following NFPA 13, Standard for the Installation of Sprinkler Systems. NFPA 13R, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and Including Four Stories in Height. NFPA 14, Standard for the Installation of Standpipe and Hose Systems. NFPA 15, Standard for Water Spray Fixed Systems for Fire Protection. NFPA 16, Standard for the Installation of Foam-Water Sprinkler and Foam-Water Spray Systems. NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection. NFPA 22, Standard for Water Tanks for Private Fire Protection. NFPA 24, Standard for the Installation of Private Fire Service Mains and Their Appurtenances. NFPA 750, Standard on Water Mist Fire Protection Systems. For systems originally installed in accordance with one of these standards, the repair, replacement, alteration or extension of such systems should also be performed in accordance with that same standard. When original installations are based on other applicable codes or standards, repair, replacement, alteration, or extension practices should be conducted in accordance with those other applicable codes or standards.
The 2011 NFPA 25 will raise confidence in every fire protection plan.
Sprinkler systems can reduce the average property loss by 71% in the event of a fire. However, improper maintenance can result in less sprinkler effectiveness or even failure. Changes in NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems will help maintenance professionals, inspectors, and building owners keep systems ready to respond.
Revised Chapter One clarifies NFPA 25's scope and purpose.
NFPA 25 is so essential to proper sprinkler care, it's adopted by jurisdictions nationwide, and NFPA 13 requires installers leave a copy of NFPA 25 with property owners. Revised Chapter One clarifies the role NFPA 25 plays in a fire protection plan. It's the only source for the latest rules on fire sprinkler systems including foam-water and fixed water spray systems, standpipe and hose systems, fire pumps, fire service piping and appurtenances, and water storage tanks.
Major revisions
· New terms define "critical deficiencies" and "noncritical deficiencies," so maintainers and owners can determine corrective actions and prioritize repairs.
· Updated testing frequencies are based on the growing database of inspection, testing, and maintenance records. Maximize time and efficiency without compromising reliability.
· Other revisions clarify the roles and responsibilities of the building owner and the designated owner's representatives. This helps avoid critical oversights in sprinkler care.
· Use all-new Annex E classifies sprinkler repairs. Real-world examples of sprinkler repairs and their classifications are based on the new terms for critical and noncritical deficiencies.
· The Hazard Evaluation Form in Annex F will help you identify how changes in building occupancy, use or process, or materials used or stored could impact the adequacy of the fire protection systems.
Be confident sprinklers will respond when needed! Reduce risk with the 2011 NFPA 25. (Softbound, 120 pp., 2011)
