Myths and Facts about Sprinkler Systems

Automatic sprinkler systems have sustained an enviable record of protecting life and property for over 100 years. Yet, there are still common misunderstandings about the operation and effectiveness of automatic fire sprinkler systems:

Myth: "Water damage from a sprinkler system will be more extensive than fire damage." 
Fact: Water damage from a building sprinkler system will be much less severe than the damage caused by water from fire fighting hose lines or smoke and fire damage if the fire is allowed to spread. Quick response sprinklers release 8-24 gallons of water per minute compared to 80-125 gallons per minute discharged by a fire hose.
   
Myth: "When a fire occurs, every sprinkler head goes off."
Fact: 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.
   
Myth: "A smoke detector provides enough protection."
Fact: Smoke detectors save lives by providing an early warning to a smoke or fire incident, but can do nothing to extinguish a growing fire or protect those physically unable to escape on their own, such as the elderly or small children. Too often, battery operated smoke detectors fail to function because the batteries are dead or have been removed. As the percent of homes in America that were "protected" with smoke detectors increased from zero to more than 70%, the number of fire deaths in homes did not significantly decrease. 
   
Myth: "Sprinklers are designed to protect property, but are not effective for life safety."
Fact: 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%.
