    1. 1. Carbon MonoxideThe “Invisible Killer”
    2. 2. Objectives Define carbon monoxide Describe possible sources Identify carbon monoxide poisoning signs and symptoms Understand who is at risk for poisoning Describe key prevention tips and available resources Review FD’s role, forms, SOG and CO detecting equipment.
    3. 3. What is Carbon Monoxide Poisoning? CO is a by-product of incomplete combustion of natural gas, propane, gasoline, coal, oil, kerosene, and wood. CO is colorless, tasteless, odorless Source: Center for Disease Control
    4. 4. Carbon Monoxide (CO) vs. Carbon Dioxide (CO2)Carbon Monoxide Carbon DioxideA byproduct of burning Gas exhaled with normalfuels breathingA poison even at low An asphyxiant anddoses poisonous at high doses Source: Vermont Department of Health
    5. 5. Who is at Risk? EVERYONE, especially: – People using alternate heat sources during power outages – Elderly – Unborn babies, infants, – Individuals with chronic heart disease, anemia or respiratory problems Source: Center for Disease Control and
    6. 6. Who is at risk? Cont…..– Personnel at fire scenes (fire-fighters/rescue workers)– Individuals working with combustion engines or combustible gases indoors– Industrial workers at pulp mills, steel foundries and plants producing formaldehyde and coke– Pets Source:
    7. 7. Is CO Poisoning Common? One of the leading causes of unintentional/accidental poisoning deaths in the United States Poisonings occur more often in the fall and winter months Accounts for approximately 50,000 emergency department visits each year in the U.S. For information on the CDC study “Unintentional non- fire related CO Exposures in the U.S. in 2001-2003 visit Source: Olson: Poisoning and Drug Overdose
    8. 8. Sources Burning fuels such as: wood, oil, natural gas, gasoline, kerosene, propane, coal and diesel  Electrical appliances do not produce CO Common sources of human exposure include: – Smoke inhalation from fires – Automobile exhaust – Faulty or poorly vented charcoal, kerosene or gas stoves – To a lesser extent, cigarette smoke and methylene chloride (industrial uses) Source: NNEPC, Vermont Department of Health, the Environmental Protection Agency and Olson: Poisoning and Drug Overdose
    9. 9. Cold Weather Hazards Insufficient ventilation – Generators used inside during a power outage – Gas or kerosene heater in room without proper ventilation – Stoves or fireplaces that are improperly vented or blocked – Exhaust flues or appliance ducts that are blocked or sealed shut – Cars or trucks idling in a garage  Opening the door is not sufficient Source: Environmental Protection Agency, Center for Disease Control and the Vermont Department of Health
    10. 10. Cold Weather Hazards cont…. Poor function or worn parts – Appliances and equipment – Heating systems Improper use – Using charcoal grills indoors – Heating homes with gas ovens
    11. 11. Warm Weather Hazards Enclosed area (poor ventilation) – Gas, kerosene, charcoal, propane or hibachi grills – Gasoline-powered equipment (lawnmower, chainsaw, generator), used in a home, garage or under a tarp – Gas-fueled lanterns and stoves burned inside a tent, trailer, boat cabin without proper ventilation Source: Environmenal Protection Agency
    12. 12. Warm Weather Hazards cont… Excessive inhalation of exhaust fumes – Teak surfing or pulling a skier from a boat’s diving platform – Diving from or swimming near a houseboat platform – Riding in the back of a pickup truck with a camper shell
    13. 13. How does Carbon Monoxide Poisoning Work?Enters the body through the lungs and is delivered to the blood Red blood cells pick up CO instead of oxygen – Hemoglobin likes CO 250 times more than oxygen CO prevents the oxygen that is present from being readily released to and used properly by tissues
    14. 14. Why Do We Need Oxygen? Brain damage – Can only live a few minutes without oxygen. Organ damage – Vital organs such as brain and heart need oxygen Possibly death Source: Illinois & Vermont Department of Health
    15. 15. Toxic effects = Concentration X ExposureLong-term Short-termexposure to low May exposure to highlevels of CO = levels of CO Source: Vermont Department of Health, Consumer Product Safety Commission, Environmental Protection Agency
    16. 16. What do the numbers mean?Concentration of CO in air (Parts per millions) 50ppm - Threshold limit value for no adverse effects even with 6-8 hours exposure 200ppm – Possible mild headache after 2-3 hours 400ppm – Headache and nausea after 1-2 hours 800ppm – Headache, nausea, and dizziness after 45 minutes; collapse and possible unconsciousness after 2 hours Source – NFPA Carbon Monoxide – Risks At Home Fact Sheet
    17. 17. Numbers Cont…. 1000ppm – Loss of consciousness after 1 hours 1600ppm – Headache, nausea and dizziness after 20 minutes 3200ppm – Headache and dizziness after 5-10 minutes; unconsciousness after 30 minutes 6400ppm – Headache and dizziness after 1-2 minutes; unconsciousness and danger of death after 10-15 minutes 12,800ppm – Immediate physiological effects; unconsciousness and danger of death after 1-3 minutes Source – NFPA Carbon Monoxide – Risks At Home Fact Sheet
    18. 18. Signs and Symptoms Flu-like symptoms (without fever or runny nose) including: – Headache – Fatigue/sleepiness – Shortness of breath – Nausea – Dizziness – Confusion or disorientation Young children, elderly and household pets are usually effected first Source: Illinois & Vermont Department of Health, Environmental Protection Agency
    19. 19. Failure to Detect Danger Often mistaken for the flu, food poisoning or other illnesses Those sleeping or intoxicated can die before experiencing any symptoms Prolonged exposure can lead to brain damage and death Victims may become disoriented and unable to save themselves Source: Center for Disease Control , Environmental Protection Agency, Medlineplus
    20. 20. Prognosis Difficult to predict the long-term effects of CO poisoning/exposure. – Even with proper medical treatment a few people can develop long-term brain damage. – Some individuals appear to have no long-term affects. If pregnant, fetal complications or death may result.

    21. 21. Carbon Monoxide Alarm Your best protection! Install a carbon monoxide alarm close to sleeping areas. For more protection: – Install one with 15’ of each bedroom – Install one on every level of your home Never ignore a carbon monoxide alarm, IT COULD SAVE YOUR LIFE!
    22. 22. Illinois Law CO Alarm Requirement Effective January 1, 2007, every Illinois home is required to have at least one carbon monoxide alarm in an operating condition within 15 feet of every room used for sleeping purposes. Homes that do not rely on the burning of fuel for heat, ventilation or hot water; are not connected to a garage; and are not near a source of carbon monoxide (as determined by the local building commissioner) are not required to install carbon monoxide detectors. (Public Act 94-741)  OFSM version of the law - Source: Illinois Department of Public Safety/Division of Fire Safety, OSFM
    23. 23. Prevention Tips: Don’t… Never run a portable generator, gasoline- powered engines (such as mowers, snow- blowers, chainsaws) or burn charcoal in: - Crawlspaces - Closed in porch - Indoors - Vehicle - Garages - Tent - Basements - Under windows Never leave a car, mower or other vehicle running in a garage, even with the door open Do not heat home with gas oven. Source: Center for Disease Control and the Environmental Protection Agency
    24. 24. Visual Warning Signs Streaks of carbon or soot around door of your fuel-burning appliance. No draft in the chimney. A large amount of rusting on flue pipes or appliance jackets or vent pipes. Moisture on windows/walls of furnace doors. Source: Consumer Product Safety Commission, Underwriters Laboratories Inc.
    25. 25. Visual Warning Signs Cont…. Discolored or damage bricks at top of chimney. Soot falling from fire place. Flu-like symptoms that go away when you leave home and come back when you re- enter. Source: Underwriters Laboratories Inc.
    26. 26. Fire Department’s Role Use special detectors that monitor parts per million (PPM) of the atmosphere at any given location. – Find source of CO – Can detect small amounts of CO If CO is detected: – The source will be investigated and identified – Next steps will be recommend – The area will be ventilated until CO levels are safe
    27. 27. Fire Department’s Role Cont… Remove Occupants Clearing the building – Positive pressure ventilation will clear the building quickly, however, the gas fired engine on the fan will be introducing CO into the building. – Use electric fans, or household exhaust fans whenever possible. – Open windows & use natural ventilation.
    28. 28. NWFD ProceduresSOG # 61 – Carbon Monoxide Response Non-urgent unless reports of medical problems If dispatcher does not relay information, ASK Activate detector and wear appropriate PPE (including SCBA) Investigate all areas of the building in a systematic order. Use the Checklist Check vented appliances for an updraft Any levels of CO shall result in FD shutting gas off to the residence, or appliance Go thru questions with each occupant of the building. ANY YES ANSWER GETS PARAMEDIC RESPONSE. Leave final form indicating highest level of CO found in the building.
