1
Residential Fire Sprinklers
2
What is the leading cause of fire?
  • Men
  • Women
  • Children

3
Will we stop responding to incidents?
  • Not likely!

4
Do you know these children?
  • Jordan Tinsley Age 9
  • John Tinsley Age 7
  • Benjamin Tinsley Age 6
  • Died early morning June 25, 2007, from a house
    fire near Texarkana, Texas.

5
2007 Year-to-Date Multiple Fatality Fire Deaths
  • Fires 113
  • Deaths 431
  • Adults 197
  • Children 234

6
Fire Death and Injuries in One- Two-family
Dwellings (Percentage of Residential)
  • Fire deaths 83
  • Fire injuries 74
  • Fire property damage 83
  • Fireground firefighter deaths 70
  • 2004 NFPA

7
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.

8
Unlike what TV and movies show, only when
sufficient heat is present will a sprinkler
discharge water.
9
How safe are you?
  • 80 of all fires start in the home. While most
    start during the day, most fatal fires occur at
    night
  • Americans suffer an unwanted fire every 10
    seconds
  • Every 74 seconds a fire is of enough magnitude to
    call the Fire Dept.
  • More than 3,000 people died in fires in 2005.
  • 19,300 people are injured in home fires each year
  • There is a 1 in 200 chance of fire in your home
    during your lifetime

10
How does time affect the Fire Departments
ability to deliver service?

12
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

13
NFPA 13D Sprinkler systems One / Two Family
Dwellings
  • 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

14
NFPA 13 Systems
  • NFPA 13 systems are for commercial occupancies
  • Designed primarily for property conservation
  • The average sprinkler head 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)
  • Life safety is a byproduct of the system

15
NFPA 13D systems
  • Are designed for 1 and 2 family dwellings
  • Designed primarily for life safety only but will
    contain or frequently extinguish the fire
  • The average sprinkler head discharges 13 to 18
    gallons per minute
  • Sprinkler heads are located in paths of egress
    only bedrooms, hallways, kitchens, dining rooms
    and laundry rooms - none in attics, crawl spaces,
    closets (size dependent) or bathrooms (size
    dependent)
  • This coverage provides fire protection from 83
    of all areas fire originates
  • Systems are designed for the flow of 1 to 2
    sprinkler heads

16
Types of Sprinklers
Residential
Commercial
17
Where is the sprinkler?
18
Multipurpose Systems
  • Part of the cold water loop in the house.
  • Reduces the chance of freezing.
  • Placing back into service after activation
    ensures repair.
  • No additional backflow prevention.

19
Are Sprinkler Systems Effective?
20
Green Effect
  • Reduces the amount of water needed to extinguish
    a fire.
  • Smoke production is minimal
  • Natural resources such as lumber is not needed to
    rebuild the home

21
Myths Facts
  • Myth Sprinkler heads activate accidentally
  • Fact 1 in 16,000,000 chance of accidental
    activation
  • Myth All sprinklers go off
  • Fact Sprinklers react to heat, only those
    exposed will activate
  • Myth Sprinkler heads will leak
  • Fact Operate at the same water pressure as
    your plumbing but tested 2-3 times higher at
    installation
  • Myth Sprinklers are unsightly
  • Fact Sprinklers can be recessed into the
    ceiling

22
Myths Facts
  • Myth Too expensive
  • Fact Approx. 1-2 of the homes cost
  • Myth They cause water damage
  • Fact Damage is substantially less than damage
    caused by the fire department if sprinklers are
    not present.
  • Myth Residential fire sprinklers dont save
    lives
  • Fact There has not been a fatality in a home
    with residential fire sprinklers in Napa, CA or
    Cobb County, GA. Scottsdale, AZ credits
    sprinklers for saving 52 lives since 1985 when an
    ordinance was enacted.
