Be Alert

The symptoms of carbon monoxide poisoning are similar to those of the common flu.

Carbon monoxide is an odourless gas and when inhaled, it depletes oxygen in your blood cells. Exposure time has a bearing on the severity of the following symptoms:

  • Low Concentration - Slight headache and/or shortage of breath during moderate physical activity
  • Higher Concentration - Severe headache, dizziness, nausea, vomiting, mental confusion, weakness, vision and hearing impairment, collapse or fainting during exertion, loss of muscle control and/or drowsiness
  • Extreme Concentration - Unconsciousness, brain damage or death.

When you inhale carbon monoxide, you could experience any of these symptoms. If any member of your household is affected, or if the symptoms are less evident or disappear altogether when you leave home, it's potentially the result of carbon monoxide exposure; so take immediate action. Note: the young, the elderly or the infirm are most quickly affected by Carbon Monoxide.

What to do you if you suspect Carbon Monoxide is present?

  • Evacuate the building of all people and pets immediately, then once safely out;
  • Contact our 24 hour emergency line at 1-866-222-2068 or contact 911.

What can you do to prevent CO poisoning?

  • Always make sure your woodburning fireplace has enough combustion and ventilation air.
  • Routinely check all gas appliances/fireplaces for proper combustion at the beginning of every heating season.
  • Never run a vehicle, snowblower or lawnmower in a closed garage.
  • Never use a charcoal, propane or natural gas barbecue indoors.
  • Never run exhaust fans, power attic vents or a central vacuum system for prolonged periods.
  • Never use a gas range or unvented space heater to heat your home.
