Fire Sprinklers Save Lives
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.
Except
in specially-designed systems, 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 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.
Conclusion
The National Fire Protection Association outlines several major
strategies that are key to reductions in fire losses and especially
in home fire deaths, which are 78.3% of the total fire deaths.
They are:
- More,
and more widespread, public fire safety education on how to
prevent fires and how to avoid serious injury or death if fire
occurs.
- Residential
fire safety initiatives remain the key to reductions in the
overall fire death toll.
- Wider
use and proper maintenance of smoke detectors, coupled with
practiced home escape plans.
- Wider
use of residential sprinklers.
- Additional
efforts to make home products more fire-safe, such as less
fire-prone cigarettes and child-resistant lighters.
- Addressing
the special protection needs of high-risk groups, such as
the young, older adults and the poor.
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 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 firehose.
Myth
2: "When a fire occurs, every sprinkler head goes
off."
Fact: Sprinkler heads are individually activated
by fire. 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 that occurred in sprinklered buildings 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%. |
