More Fire Facts

Young children, older adults, and physically and
mentally challenged people face the highest risk of
injury or death in residential fires.
Too
often, people fail to respond appropriately to
the sound of a smoke detector, because they
assume it is a false alarm. Rather that exiting the
building, they search to confirm the existence of a
fire, wasting the few precious minutes they may
have to escape.
Fire sprinkler facts
• Only the sprinkler closest to the fire will activate,
spraying water directly on the fire.
• Each sprinkler is individually activated by heat.
• 90% of all home fires are contained with a single
sprinkler.
• The odds of accidental activation are 1 in 16
million.
How does a home fire sprinklers’ discharge
compare to a fire hose attack line discharge?
•A residential low flow pendant sprinkler head delivers
approximately 13 to 18 gallons per minute of water
•A fire hose attack line delivers 200 gallons per minute (this
does not include a backup line which would double the flow
of water)
Sprinkler systems
represent a choice, a little
water when the fire starts
or a lot of water when the
fire department arrives
But what about Water Damage?
•Average water usage for sprinklered home - 341 gallons
•Average water usage for unsprinklered home 2935 gallons
•Average repair costs for sprinklered home $2,166 dollars
•Average repair costs for unsprinklered home $45,019 dollars
With both smoke detection and sprinklers,
death, injury by fire is reduced by 82%
Sprinklers also have a “green value”. Since less
water is applied to the fire, less contaminated
runoff is produced, additionally water mains are
not disturbed creating water clarity issues.

It is time to realize that firefighting involves
fighting time, not fire.
2 minutes
4 minutes.
7 minutes.
The standard time-temperature curve shows that
temperatures can reach over 1,000°F in five minutes and
flashover can begin as early as 7½ minutes after ignition.

Home Fire Sprinklers and
Firefighter Safety
Firefighter Injuries / Deaths by
Occupancy
• More injuries to firefighters occur in one
and two family dwellings than any other
occupancy
• 44% of all Line of Duty deaths occur in
one and two family dwellings
• One and two family dwellings are a greater
danger to firefighters than all other
occupancies combined
Effects of Injury / Death
• The costs to the community to
rehabilitate a firefighter from injuries
sustained in the line of duty are 10
times greater than that of a death
• This does not factor in the emotional
issues to the family, friends, loved ones
and fire department
But what about Smoke
Detectors?
• Smoke detectors have a 10 year life
expectancy
• It is stated that there are more non
functioning / aged out smoke detectors in
homes than there are homes without any
smoke detectors.
• When is the last time you personally
checked your smoke detectors and what is
the age of your device(s)?
But what about Smoke
Detectors (cont.)
• Smoke detection is a “passive” device that
only warns of impending danger
• Dependent on the type of fire and the
specific smoke detection device, response
to the condition could provide little time to
initiate escape
How well does smoke detectors
work?
• From 1989 to 1999, a fatality occurred in 1
of every 5 residential fires with working
smoke detectors
• From 1999 to 2001, a fatality occurred in 1
of every 3 residential fires with working
smoke detectors
How well does smoke detection
work (cont.)
• Only 58% of children ages 6 to 12 was
awakened by the sound of a smoke
detector activation
• Of this 58%, only 38% of those awakened
successfully evacuated the residence
What about Residential
Sprinklers?
• The purpose is to prevent Flashover,
control / contain the fire, but will often
extinguish same
• Keeps smoke, heat and products of
combustion at a survivable level for
occupant egress
• Temp. at eye level
• Temp. at ceiling level
• Maximum CO level
200 degrees
500 degrees
1500 ppm
How does NFPA 13
systems compare with
NFPA 13 D systems?
NFPA 13 Systems
• NFPA 13 systems are designed for commercial occupancies
• The average sprinkler head (SSP, SSU) discharges 25 to 35
gallons per minute.
• Sprinkler heads are located “everywhere” – attics, basements,
crawl spaces, closets and concealed spaces
• Systems are designed for the flow of multiple heads (12-15 on
average)
• Required FDC and hydrostatic test of 200 psi
• Designed primarily for property conservation
• Life safety is a byproduct of the system
NFPA 13D systems
•
Are designed for 1 and 2 family dwellings
•
The average sprinkler head discharges 13 to 18 gallons per minute
•
Required Sprinkler heads are located in paths of function / egress only – bedrooms,
hallways, kitchens, dining rooms and laundry rooms - none in attics, crawl spaces closets (size dependent, does not exceed 24 square ft. & least dimension does not
exceed 3 ft.) or bathrooms (size dependent, 55 square ft. or less )
•
This coverage provides fire protection from 83% of all areas fire originates – (Living
room 41%, Bedroom 27%, Kitchen 15%)
•
Systems are designed for the flow of 1 to 2 sprinkler heads – (typical k-factor 4.5 to
4.9). This represents a density of .05 gpm per square foot
•
Typically, no required FDC and hydrostatic test done at normal system operating
pressures
•
Designed primarily for life safety only but will contain or frequently extinguish the fire

NFPA 13D Sprinkler system costs
• Typical cost for new construction in a single family home with a
good municipal water supply – between $.50 and $2.00 per
square foot
• Auxiliary water supply is not needed due the domestic water
supplying the sprinkler system**
• With the sprinkler system supplying the cold water distribution,
additional cost is negligible**
• ** multi-purpose system (sprinkler system is designed with a 5
gpm background demand for domestic water use)
What if I am on a Well?
• While a municipal water supply is the best
water supply source, a stored water
source is also permitted. A 10 minute
water supply is needed for a 2 head
activation (generally 300 to 400 gals.) The
addition of a storage tank and pump
assembly adds approximately $1,500 to
2,000 to the system cost.
Typical connection to municipal
water
1” feed or greater
Additional Bonuses for MultiPurpose systems
• Sprinkler system cannot be shut off independent of the
domestic water use
• With domestic water service being supplied by sprinkler
system, the chance of system freezing is greatly reduced
• With the domestic system supplying the sprinklers,
additional swing check or backflow prevention valves are
not necessary. This gives addition pressure and volume to
the sprinklers and saves money on the installation of the
system

How Are We Going to Reduce
Costs?
Reduce the number of sprinklers in the design to
two(We know over 90% of the time only two go
off, so only design for two)
This results in less water required
This results in less pressure required to push it
This results in smaller (less expensive) pipe
How Else Are We Going to
Reduce Costs?
Reduce the cost of materials and installation
•
Lower schedules of steel pipe
•
CPVC or PEX plastic pipe
Use non listed components where not critical to
life safety
•Tanks pumps, hangers, waterflow detection
devices & waterflow valves
How Else Are We Going to
Reduce Costs?
Omit sprinklers in certain locations
•
Areas not critical to life safety
How do we know where to omit them?
•
We need to know, not just where fires start,
but where fires start that KILL people

Here’s What’s At the
Bottom of the List(other)
Sprinklers shall be installed in all areas Except:
• Bathrooms less than 55 ft.2
• Clothes closets, linen closets and pantries
less than 24 ft.2 least dimension 3 ft.
• Garages, carports & open attached porches
• Attics, crawl spaces and concealed spaces
• Entrance foyers (if a second exit is provided)
How Else Are We Going to
Reduce Costs?
Reduce the water supply requirements
We’ve already reduced the number of heads in our
design to two
•
Lower the flow requirements from .10 to
.05gpm/ft2
•
Lower the duration requirement to 10
minutes (7 mins. if it is a single story home <
2000 ft.2)
How Else Are We Going to
Reduce Costs?
Regardless of what we do with the water
supply,
SPRINKLER SYSTEMS ARE ALWAYS
DESIGNED TO MEET THE ABILITIES
OF THE WATER SUPPLY, NOT VICE
VERSA
Improve Aesthetics
• Make them smaller
• Make them concealed, recessed
• Offer them in various colors / shades
