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
u p 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
sprinklering 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.
