Myths and Facts About Sprinkler Systems (Part 1)
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 firefighting 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°F. 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.
