Residential fires are usually controlled with how many operating sprinkler heads? -
Answer -✔✔one, Usually, a single sprinkler is enough to put out a fire before it gets out
of control.
What causes a fire sprinkler to activate? - Answer -✔✔Heat from a fire expands the
liquid in a glass bulb and breaks it, which opens the sprinkler orifice and allows water to
flow.
"When a fire occurs, every sprinkler goes off." - Answer -✔✔false:Sprinklers are
individually activated by heat.
Residential fires are usually controlled with one operating sprinkler.
Ninety percent of all commercial fires are controlled with six or fewer sprinklers.
"A smoke detector is enough protection." - Answer -✔✔false,Smoke detectors can save
lives by providing a warning system but can't extinguish a fire or protect those physically
unable to escape on their own, such as the elderly or small children.
Though nearly 90 percent of U.S. homes have at least one smoke detector, only 60
percent have working detectors, often because of dead or missing batteries.
"Water damage from a sprinkler system will be more extensive than fire damage." -
Answer -✔✔false,
Water damage from a fire sprinkler system is generally much less severe than the
damage caused by water from fire-fighting hose lines or smoke and fire damage if the
fire goes unabated.
In residences with fire sprinklers, property losses are 85 percent less when compared to
those without sprinklers.
Quick response sprinklers release 13-24 gallons of water per minute compared to 100-
250 gallons per minute released by a fire hose.
