Life SafetySprinkler system effectiveness in terms of life safety is best summarized by the following statement, which is based on fire incident data: ‘‘NFPA has no record of a fire killing more than two people in a completely sprinklered building where the system was properly operating."
A fire sprinkler system that is properly installed and maintained can provide protection against loss of life and property in the event of a fire. The fire sprinkler system consists of a water supply, which provides adequate pressure and flow rate to a water distribution piping system, onto which fire sprinklers are connected.
In the event of a fire, an automatic fire sprinkler will allow water to flow from the sprinkler when it is exposed to sufficient heat to release a heat sensitive element (fusible link or glass bulb). Only sprinklers subjected to a temperature at or above their specific temperature rating will operate.
Sprinklers Are Designed to Protect Property
Sprinklers provide a high level of life safety. Statistics reveal that there has never been any multiple loss of life in a fully sprinklered building. Property losses are 85% less in residences with fire sprinklers compared to those without sprinklers.
The combination of automatic sprinklers and early warning systems in all buildings could reduce overall injuries, loss of life and property damage by at least 50%.
When a Fire Occurs, Sprinkler Heads Go Off Individually
Sprinkler heads are individually activated by fire temperatures in excess of 155°.
Residential fires are usually controlled with one sprinkler head. 90% of all fires are controlled with six or fewer heads and a study conducted during 80 years of automatic sprinkler use found that 82% of the fires that have occurred were controlled by two or fewer sprinkler heads.
