Prevent fire tragedies and loss with sprinkler care based on NFPA 25.
Improper maintenance of automatic sprinkler systems can result in less effectiveness, reduction of service life, or even catastrophic failure. That's why maintenance professionals, inspectors, and building owners rely on NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. Maximize time and efficiency without compromising reliability with requirements governing 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. The Standard 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.
The 2014 edition of NFPA 25 offers comprehensive guidance on maintaining suppression systems for optimum performance, and this edition introduces an expanded scope that includes water-mist systems. Changes include updated fire pump operating test-frequency rules; new fuel-supply testing procedures for diesel-driven fire pumps; a modified definition of "sprinkler system" for consistency with NFPA 13: Standard for the Installation of Sprinkler Systems; clarification about inspecting the insides of sprinkler pipes; as well as the addition of valve status testing to ensure water is reaching the sprinkler system.
The 2011 edition of NFPA 25 clarifies the role the Standard plays in a fire protection plan. New terms in this edition define "critical deficiencies" and "noncritical deficiencies," so maintainers and owners can accurately identify corrective actions and prioritize repairs. Updated testing frequencies are based on the growing database of inspection, testing, and maintenance records. Other revisions clarify the roles and responsibilities of the building owner and the designated owner's representatives, to avoid critical oversights in sprinkler care. New Annex E classifies sprinkler repairs and has examples of sprinkler repairs and their classifications based on the new terms. A new Hazard Evaluation Form in Annex F helps you identify how building renovations could impact the adequacy of fire protection systems.
The 2008 edition of NFPA 25 introduces guidelines for a performance-based testing option that offers alternate, flexible means of compliance. While the previous edition of the Standard included performance-based testing on a limited basis in the "equivalency" option, the 2008 edition presents practical guidance on how to implement and monitor the process, subject to approval by the Authority Having Jurisdiction (AHJ). New coverage includes what variables to take into account when adjusting frequencies, which factors to consider in the transition to a performance-based test program, and how to establish a failure rate -- complete with suggested calculation methods and examples. Other changes include new component replacement testing tables for each type of water-based system, first-time coverage of dry pipe system testing, a new chapter on water mist systems maintenance, and a new impairment procedures requirement.
The 2002 edition of NFPA 25 adds new testing requirements for dry sprinklers, revised 5-year water tank inspection requirements, and new timing for testing of waterflow and supervisory switches. Other changes permit the use of ultrasonic (UT) and radiographic (RT) examinations to comply with obstruction investigation provisions. The 2002 edition also expands guidance for detecting Microbiologically Influenced Corrosion (MIC) and strategies for treatment.
