The Facts

• Automatic fire sprinklers have been in use in the U.S. since 1874.
• Fire sprinklers are widely recognized as the single most effective method for fighting the spread of fires in their early stages - before they can cause severe injury to people and damage to property.
• When one fire sprinkler head goes off to fight a fire the entire sprinkler system does NOT activate. Sprinklers react to temperatures in individual rooms.
• The chances of a fire sprinkler accidentally going off are extremely remote.
• Installation of fire sprinklers can provide discounts on insurance premiums.
• The costs for installing fire sprinkler systems in buildings 6 to 8 stories high ranges from under a dollar to about $2.00 per square foot in most new construction and from about $1.50 to $2.50 per square foot for retrofitting sprinklers in existing buildings.
• The installation of fire sprinklers in new residential construction is estimated to make up around 1% of the total building cost. (Similar to the cost of new carpet)
• Over 200 U.S. communities have residential sprinkler laws. Roughly 100 of these communities are in California. In downtown Fresno for example, there has been fire damage of only $42,000 during a 10-year period in which its sprinkler law has been in effect.
• According to the National Fire Protection Association, property damage in hotel fires was 78% less in structures with sprinklers than it was in structures without sprinklers during the years 1983-87. (Average loss per fire was $2,300 in sprinklered buildings and $10,300 in unsprinklered buildings.)
• Nearly half of all hotels and motels, according to a 1988 survey by NFPA, have sprinkler systems.
• NFPA has no record of a fire killing more than two people in a completely sprinklered building where the system was properly operating, except in an explosion or flash fire or where industrial fire brigade members or employees were killed during fire suppression operations.

MYTHS AND FACTS ABOUT AUTOMATIC FIRE SPRINKLERS

Automatic sprinkler systems have enjoyed 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 1: "Water damage from a sprinkler system will be more extensive than fire damage."

Fact: Water damage from a home 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 goes unabated. Quick response sprinklers release 8-24 gallons of water per minute compared to 50-125 gallons per minute released by a fire hose.

Myth 2: "When a fire occurs, every sprinkler head goes off."

Fact: Sprinkler heads are individually activated by fire. Residential fires are usually controlled with one sprinkler head. 90% of all fires are controlled with six or fewer heads and a study conducted in Australia and New Zealand covering 82 years of automatic sprinkler use found that 82% of the fires which occurred were controlled by two or fewer sprinklers.

Myth 3: "A smoke detector provides enough protection."

Fact: Smoke detectors save lives by providing a warning system 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 4: "Sprinklers are designed to protect property, but are not effective for life safety."

Fact: Sprinklers provide a high level of life safety. Statistics demonstrate 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 and residences could reduce overall injuries, loss of life and property damage by at least 50%.
