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 (=>3) 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


• 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

Required by law:


• 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


• 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

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 sprinkler/years

onset time flow time flow rate total flow Sprinklers immediate 2 – 8 min 30 GPM 240 GALFirefighters who knows ? 6 – 8 min 300 GPM 3200 GAL


• 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

DESIGN CONSIDERATIONS


• Be realistic

• Build your case

• Work out the technical details

• Know when to back off

• Sprinkler your own home

• Keep up the public education

IT SAYS

PREVENTION !!

Carbon Monoxide Detectors

CARBON MONOXIDE

• A natural byproduct of combustion, present whenever fuel is burned

• Colorless

• Odorless

• Same density as air (but rises if warm)

CARBON MONOXIDEinjuries

• # 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

CARBON MONOXIDEsymptoms

• Headache

• dizziness

• nausea

• shortness of breath

• fatigue

• Flu-like symptoms

CARBON MONOXIDEprotection

• 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

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’


• 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


• About 6 million households now have CO detectors

• Chicago, IL: required in all new residential construction and when new heating equipment installed (1994)


• Compliant with UL standard 2034

• Compliant with IAS 6-96 standard

• Compliant with NFPA Suggested Practice 720 (1998)

• AC power with battery backup

DESIRABLE CRITERIA

CARBON MONOXIDE DETECTORSUL 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




• 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

CPSC RECALL, MARCH 1999


AC Battery

• 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

• 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
