SMOKE DETECTORS
  • KNOWING THAT THE HOUSE IS ON FIRE IS NOT
    HELPFUL TO PEOPLE THAT CANNOT ESCAPE
  • UP TO 25 DO NOT ALARM IN PRESENCE OF
    SMOKE
  • MILLIONS OF SMOKE DETECTORS ARE OVER 10
    YRS OLD
  • SMOKE DETECTORS DO NOT DETECT CARBON
    MONOXIDE
  • SMOKE DETECTORS ARE THE LEAST USEFUL TO
    THE PEOPLE WHO NEED THEM THE MOST

REF NFPA JOURNAL 9/10 1997

NEW TECHNOLOGY
  • CARBON MONOXIDE DETECTORS
  • RESIDENTIAL SPRINKLERS

(used IN ADDITION to smoke detectors)

THERE HAS NEVER BEEN A MULTIPLE (gt3) LOSS
OF LIFE IN A FULLY SPRINKLERED BUILDING
!

RESIDENTIAL SPRINKLERS
  • Expanded role from property protection to life
    safety
  • Development funded by USFA, 1976
  • Fast response
  • Different pattern (1 head per room)
  • Covers 400 square feet

10
RESIDENTIAL SPRINKLERS
Required by law
  • San Clemente CA (1980) (prop 13) all new
    residential construction
  • Orange and Los Angeles Counties (residences-4
    million people in 1993)
  • Greenburgh, NY (1982) all new construction
  • Prince George County, MD (1992) all new
    construction
  • Florida (1983) all public lodging and time share
    bldgs 3 stories or higher, all existing
    structures by 1988
  • 1980s Atlanta GA, Connecticut, Mass require
    retroactive sprinkler installation in existing
    high rise residential buildings
  • Hotel and Motel Fire Safety Act 1990
  • Scottsdale, AZ 1985
  • Federal Fire Safety Act- all Fed assisted high
    rise residences over 3 stories
  • ADA areas of rescue assistance

11
RESIDENTIAL SPRINKLERS
  • ISO recommendds 15 insurance reduction
  • Alaska (1981) 2 tax exemption for structures
    with fire protection systems
  • 2 20 reduction from State Farm and Allstate for
    installing sprinklers,
  • deadbolts, smoke detectors and
    central monitoring

12
RESIDENTIAL SPRINKLERS
  • Operation Life Safety (IAFC) tracks residential
    sprinkler activations
  • 1983 1995 551 activations, 35 kitchen, 15
    bedroom
  • Nearly all
    were one head activation
  • There has not been a single fire fatality in
    residences equipped with sprinklers in Napa, CA,
    or Cobb Co, GA since inception of these programs
  • There has been no fire fatality in any
    sprinklered building in PG County
  • Scottsdale 52 lives saved by sprinklers since
    1985

13
RESIDENTIAL SPRINKLERS
  • If one goes off, they all go off not true
  • They cause water damage
  • They are expensive typical new installation
    costs are 0.58 - 1.25 per
  • square
    foot. THIS IS USUALLY CHEAPER
  • THAN THE
    COST OF CARPET !
  • They go off accidentally FM experience is 1
    failure in 1 to 16 million

14
RESIDENTIAL SPRINKLERS
DESIGN CONSIDERATIONS
  • Should comply with NFPA 13D
  • Should be designed and installed by professional
    sprinkler contractors
  • House main water feed optimally should be 1.5
    inch pipe
  • Storage tank and pump with at least 10 minute
    flow capacity
  • Can share common pipe with domestic water system

15
RESIDENTIAL SPRINKLERS
PROMOTING A SPRINKLER ORDINANCE IN YOUR COMMUNITY
  • Be realistic
  • Build your case
  • Work out the technical details
  • Know when to back off
  • Sprinkler your own home
  • Keep up the public education

REF NFPA JOURNAL MARCH/APRIL 1998

RESIDENTIAL SPRINKLERS
RESOURCES
  • National Fire Protection Association
  • American Fire Sprinklers Association
  • National Fire Sprinklers Association
  • USFA

Carbon Monoxide Detectors
19
CARBON MONOXIDE
  • A natural byproduct of combustion, present
    whenever fuel is burned
  • Colorless
  • Odorless
  • Same density as air (but rises if warm)

20

21
CARBON MONOXIDE injuries
  • 1 cause of poisoning in US
  • Approximately 1500 deaths annually including 200
    deaths
  • from CO produced by home heating
    equipment
  • 10,000 annual emergency room visits
  • Children and elderly at higher risk

22
CARBON MONOXIDE symptoms
  • Headache
  • dizziness
  • nausea
  • shortness of breath
  • fatigue
  • Flu-like symptoms

23
CARBON MONOXIDE protection
  • Make sure that all fuel-burning appliances work
    properly
  • Have central heating systems inspected annually
  • Never burn charcoal or use portable camping
    equipment indoors
  • Never use the stove, oven or clothes dryer to
    heat the house
  • Never operate vehicles or gasoline powered tools
    inside the garage
  • Install carbon monoxide detectors

24
CARBON MONOXIDE DETECTORS
  • Cost 25 to 100
  • Do not detect smoke, propane or natural gas
  • CPSC carbon monoxide detectors are as important
    to home safety as smoke detectors are

25
CARBON MONOXIDE DETECTORS
  • CPSC every home should have at least one
    detector installed outside of sleeping areas
  • Additional detectors on every level and in every
    bedroom provide additional protection
  • Do not install above or near CO producing
    appliances
  • Best installed on ceiling

26
CARBON MONOXIDE DETECTORS
  • About 6 million households now have CO detectors
  • Chicago, IL required in all new residential
    construction and when new heating equipment
    installed (1994)

27
CARBON MONOXIDE DETECTORS
DESIRABLE CRITERIA
  • Compliant with UL standard 2034
  • Compliant with IAS 6-96 standard
  • Compliant with NFPA Suggested Practice 720 (1998)
  • AC power with battery backup

28
CARBON MONOXIDE DETECTORS UL Standard
  • Alarm must sound before an average, healthy adult
    begins to experience symptoms
  • OSHA 8 hr exposure 35 PPM
  • 200 PPM X 2-3 hr Headache, fatigue, nausea,
    dizziness
  • Alarm must sound before CO reaches 100 PPM over
    90 minutes
  • Alarm must sound before CO reaches 200 PPM over
    35 minutes
  • Alarm must sound before CO reaches 400 PPM over
    15 minutes

CARBON MONOXIDE DETECTORS
CPSC RECALL, MARCH 1999
  • 650,000 Kidde Nitehawks
  • - mfg between 11/8/98 and 3/9/99
  • - labeled in front carbon monoxide alarm
  • - units labeled carbon monoxide detector
  • are OK
  • 350,000 Kidde Lifesavers model 9CO1 or
  • 9CO-1C mfg between 6/1/97 and 1/31/98
  • 18,700 Sinostone SC-01 detectors recalled in 1996
    by CPSC

31
CARBON MONOXIDE DETECTORS AC
Battery
  • Same
  • Install anywhere
  • Battery change
  • Sensor needs changing every 2-3 yr
  • Reaction time depends on concentration
  • and duration of exposure
  • Reset time depends on exposure time and may
    require removal of sensor
  • Silence buttons now required
  • Cost 30 - 50
  • Requires wiring
  • No maintenance required
  • Sensor gets more sensitive with age
  • Gives continuous display of CO level
  • Updated every few minutes
  • Resets immediately when CO level OK
