What is the current version of NFPA 25?
The updated and expanded NFPA 25, 2023 edition, is the most current and complete document covering inspection, testing, and maintenance of water-based fire protection systems.
What section of NFPA 25 covers ice obstruction?
section 14.4
Ice plugs. When dry or preaction systems pass through refrigerated spaces maintained at temperatures below 32°F (0°C), NFPA 25 (14.4) requires annual internal inspections for ice obstructions. Inspections are conducted at the point where piping enters the refrigerated area. If ice obstructions are found, section 14.4.
Do sprinkler heads expire?
Even with regular maintenance, sprinkler heads do not last forever. Fire safety protocol recommends you get sprinkler heads replaced once every five years to prevent fire sprinkler leaks.
How often NFPA 25 is updated?
According to NFPA 25, this is the inspection schedule you should follow: Weekly or monthly: Inspect the gauges in dry, pre-action, and deluge systems as often as once a week. Wet pipe system gauges can go a month between inspections.
Do fire sprinkler heads expire?
How often should sprinkler heads be inspected?
Every 10 years
How often should you have your fire sprinkler system tested?
| Fire Sprinkler Component | Testing Schedule |
|---|---|
| Dry sprinklers (Test or Replace) | Every 10 years |
| Fast-response sprinklers (Test or Replace) | 20 years initially, then every 10 years |
| Standard response sprinklers (Test or Replace) | 50 years initially, then every 10 years |
How do you test a sprinkler head?
How do we test the sprinklers?
- Visual inspection of 100% of the samples.
- A minimum of 75% of the heads will be subjected to a ‘function test’ – this has two parts: a water-based test to detect leakage in the heads, and a gas flame activation test to check the satisfactory operation of the heads.
What is a valve status test?
The 2017 standard now calls it a “valve status test,” which may include the use of a main drain, but is trying to inform the inspector that the largest orifice that can be opened downstream of the cycled valve will achieve a better result for indicating a partially closed valve.
What temperature will set off a fire sprinkler?
between 155 to 165 degrees Fahrenheit
Fire sprinkler systems are actually quite sophisticated, and are designed to be heat sensitive so that sprinklers only activate when the temperatures rise to fire-induced temps, usually somewhere between 155 to 165 degrees Fahrenheit.
What are NFPA codes?
NFPA publishes more than 300 consensus codes and standards intended to minimize the possibility and effects of fire and other risks. NFPA codes and standards, administered by more than 250 Technical Committees comprising approximately 8,000 volunteers, are adopted and used throughout the world.
