Here are some prevention and safety tips for consumers to avoid exposure to carbon monoxide.
Carbon Monoxide Safety Tips
Carbon monoxide cannot be seen or smelled, which is why it is known as the “silent killer,” and can overcome its victims undetected. Breathing low levels of carbon monoxide over a long period of time can also cause severe heart problems and brain damage.
How to prevent CO poisoning:
• Install Canadian-approved CO alarms on every floor of your home, especially near sleeping areas.
• Schedule regular inspections of gas appliances (e.g., furnaces, fireplaces, gas stoves, hot water heaters, boilers, etc.) by a licensed gas contractor (find a listing on Technical Safety BC’s website).
• Keep the area around your furnace clear for proper air circulation.
• Keep all air ducts, vents and screens free of obstructions.
• Never operate portable fuel-burning devices such as camp stoves, lanterns, generators, lawn equipment or barbecues indoors or in closed spaces.
• Don’t leave a vehicle engine running inside an enclosed garage or space.
• Do not close a fireplace or stove damper before the fire is completely out.
• Do not use gas-powered generators, lawn equipment or engines in enclosed areas.
Know the warning signs of CO gas at home:
• CO alarm sounds
• Loose, disconnected, water-streaked or rusty chimney vents
• Soot build-up or discolouration on fireplaces
• Discolouration of fuel-burning appliances or heating system warm air vents
• Window condensation
• Sick or dying pets or plants
If you suspect CO exposure:
• Get outside immediately.
• Once safely outdoors, call 9-1-1 for help.
• Seek immediate medical attention. CO poisoning can be fatal if left untreated. A doctor can order a blood test to measure the amount of carbon monoxide in your blood. If it is high, you may require oxygen therapy to reduce CO levels—either through a mask or via a hyperbaric chamber.
Know the symptoms of CO gas poisoning:
• MILD symptoms can be mistaken for the flu or food poisoning. They include headache, nausea and dizziness.
• STRONG symptoms include breathlessness, confusion or hallucinations.
• SEVERE symptoms are life threatening and can include collapse, convulsions or unconsciousness.
