Operation Life Safety (OLS) is alerting fire departments
to a Dateline NBC story that will raise questions about
the reliability of fire sprinklers. Dateline plans to
broadcast the story on either Sunday, March 1, Tuesday,
March 3 or Friday, March 6, 1998. The Dateline producer
was unable to confirm the exact date.
OLS is informing fire officials of the Dateline report
and is including background information for use if contacted
by the media. If possible, fire officials should contact
their local NBC television stations before the program
airs. This will allow the media to prepare the local news
with facts about the issue as well as inform their news
staff about what the fire department has done (or is doing)
to ensure that all sprinklers in their jurisdiction are
reliable.
OLS is aware of six fires in the past two years where
the sprinkler nearest to the fire failed to operate. No
injuries or deaths resulted from the fires. In each case,
the sprinkler heads were Omega model heads manufactured
by the Central Sprinkler Company. The company has manufactured
a variety of Omega models since 1983. Tests conducted
by several testing agencies have found some sprinkler
systems, where 30-40 percent of the heads needed more
than the minimum operating pressure (e.g., 10-15 psi v.
7 psi), to operate after sufficient heat was applied.
The tests also found a small number of heads actually
required much higher pressures to operate. Those heads
may not operate in a fire because the sprinkler systems
pressure may not be great enough.
The possible causes of a failure have been traced to sodium
silicates and cutting oil in the water, causing a rubber
O-ring in the Omega head to swell, and de-zincification
of the brass sprinkler frame that can leave deposits around
the opening. These problems have not affected any other
models of sprinkler heads.
Omega sprinkler heads represent less than two percent
of the total number of sprinkler heads in use (8.5 million
out of over 500 million). Further, the number of Omega
heads that may not operate in a fire is small. The vast
majority of sprinkler systems, therefore, are extremely
reliable and will provide the expected high degree of
life and property safety.
But fire departments need to ensure that fire protection
devices have as close to zero problems as possible and
thus should take immediate steps to locate all Omega heads
in their jurisdictions. They should require that sample
heads be removed and properly tested. If any heads fail
the test, the fire department should order that all of
the heads be replaced.
Fire departments can identify the models of sprinkler
heads from installation plans. If the plans are not available,
OLS can supply identification charts to assist with inspecting
each system. OLS can also supply fire officials with the
test procedure, names of testing agencies and additional
background material. Contact the OLS resource center at:

Facts about fire sprinklers:
Fire sprinklers have a superior record. They have been
installed in buildings since 1898, and about 30 million
sprinkler heads are now installed each year. The National
Fire Protection Association reports that there have been
no instances of multiple fatalities in buildings protected
with sprinklers. Fire sprinklers for residential dwellings
have been available since 1980. Jurisdictions that require
sprinklers in homes report that there have been zero fire
deaths in homes protected with sprinklers.
Sprinklers are activated by heat from a fire. The sprinkler
nearest the fire will open and control the fire with a
very small amount of water. Compared to fires in buildings
without sprinklers, fires in sprinklered buildings cause
much less property and water damage (nine to 10 times
less).
Fire sprinklers protect firefighters as well as civilians
because they quickly control or extinguish the fire before
firefighters arrive.
Fire sprinklers conserve water and fire department resources.
Fires in sprinklered buildings require one tenth the amount
of water and about one half the number of firefighters
and apparatus. Because the sprinklers quickly extinguish
the fire (or control it to a small size and area), fire
attack lines may not be needed. Also, occupants near the
fire often do not need to be rescued, and occupants in
other areas of the building often do not need to evacuate,
further reducing the demand on responding firefighters.
Operation Life Safety is a public/private partnership
of the U. S. Fire Administration, the International Association
of Fire Chiefs and private industry that advocates the
use of residential fire sprinklers and smoke alarms to
reduce deaths and injuries in residential fires.
