NFPA 25 issues guidelines of water-based fire protection systems

NFPA 25 is the baseline for inspection, testing, and maintenance of water-based fire protection systems. Compliance helps maximize system integrity to avoid failure and ensure fast, effective response in a fire emergency.

Scope

NFPA 25 establishes the minimum requirements for the periodic inspection, testing, and maintenance of water-based fire protection systems and the actions to undertake when changes in occupancy, use, process, materials, hazard, or water supply that potentially impact the performance of the water-based system are planned or identified.

Coordination with NFPA 72 Testing Requirements

NFPA 25 does not address all of the inspection, testing, and maintenance of the electrical components of the automatic fire detection equipment used to activate preaction and deluge systems that are addressed by NFPA 72.

The inspection, testing, and maintenance required by this standard and NFPA 72 shall be coordinated so that the system operates as intended.

All inspections, testing, and maintenance required by NFPA 72 shall conform to NFPA 72, and all inspections, testing, and maintenance required by this standard shall conform to this standard.

There are times when a single inspection or test can meet the requirements of both NFPA 25 and NFPA 72 (e.g., operation of a tamper switch).

Types of Systems

  1. The types of systems addressed by this standard include, but are not limited to, sprinkler, standpipe and hose, fixed water spray, private fire hydrants, water mist, and foam water.
  2. 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, are also included in this standard.
  3. This standard addresses the operating condition of fire protection systems as well as impairment handling and reporting and applies to fire protection systems that have been properly installed by generally accepted practice.

Generally, accepted NFPA installation practices for water-based fire protection systems relevant to this standard are found in the following

NFPA 13, NFPA 13R, NFPA 14, NFPA 15, NFPA 16, NFPA 20, NFPA 22, NFPA 24, NFPA 750,

* This standard does not require the inspector to verify the adequacy of the design of the system

The requirement to evaluate the adequacy of the design of the installed system or the capability of the fire protection system to protect the building or its contents, is not a part of the periodic inspection, testing, and maintenance requirements of this standard.

For example, 5.2.1.1.1 states, any sprinkler that shows signs of any of the following shall be replaced:

  1. Leakage
  2. Corrosion detrimental to sprinkler performance
  3. Physical damage
  4. Loss of fluid in the glass bulb heat-responsive element
  5. Loading detrimental to sprinkler performance
  6. Paint other than that applied by the sprinkler manufacturer.

However, the standard does not require verification that the installation is per NFPA 13, Standard for the Installation of Sprinkler Systems.

Corrective action needed to ensure that a system operates satisfactorily shall be in accordance with this standard unless this standard specifically refers to an appropriate installation standard.

For systems originally installed following one of these standards, the repair, replacement, alteration, or extension of such systems should also be performed by that same standard. When original installations are based on other applicable codes or standards, repair, replacement, alteration, or extension practices should be conducted by those other applicable codes or standards.

Unless required by Chapter 16, this standard shall not apply to sprinkler systems designed, installed, and maintained by NFPA 13D.

Purpose

The purpose of NFPA 25 is to ensure that the operational status of a system is maintained. This section also provides the AHJ with the flexibility to deal with extenuating circumstances such as a product recall or other situations specific to a particular area or project.

History has shown that the performance reliability of a water-based fire protection system under fire-related conditions increases where comprehensive inspection, testing, and maintenance procedures are enforced. Diligence during an inspection is important. The inspection, testing, and maintenance of some items in the standard might not be practical or possible, depending on existing conditions. The inspector should use good judgment when making inspections.

The purpose of this document is to provide requirements that ensure a reasonable degree of protection for life and property from fire through minimum inspection, testing, and maintenance methods for water-based fire protection systems.

In those cases where it is determined that an existing situation involves a distinct hazard to life or property, the authority having jurisdiction shall be permitted to require inspection, testing, and maintenance methods over those required by the standard.

Application

An entire program of quality control includes, but is not limited to, maintenance of equipment, inspection frequency, testing of equipment, on-site fire brigades, loss control provisions, and personnel training. Personnel training can be used as an alternative even if a specific frequency differs from that specified in this standard.

  1. It is not the intent of this standard to limit or restrict the use of other inspection, testing, or maintenance programs that provide an equivalent level of system integrity and performance to that detailed in this standard.
  2. The committee intends to recognize that future editions of this standard are a further refinement of this edition and earlier editions. The changes in future editions will reflect the continuing input of the fire protection community in its attempt to meet the purpose stated in this standard. Compliance with a future edition could be considered as providing an equivalent level of system integrity and performance of the system.
  3. The authority having jurisdiction shall be consulted and approval obtained for such alternative programs.

Compliance BD Ltd has lots of experts in NFPA certified engineers to offer fire protection systems and fire alarm and detection systems, clean agent system, gas/foam protection system, surface cooling system and MEP, HVAC, power and cogeneration system, design, consultancy, annual inspection, testing and maintenance of water-based fire protection systems and series of online and offline training that can help ensure the effectiveness of Fire Protection systems in multiple environments.
