Carbon monoxide (CO) is a colourless and odourless gas created when you burn fuels such as oil, kerosene, gasoline, diesel, coal, propane, natural gas, or wood. Exposure to CO can cause sickness and death.
Install a certified CO detector to protect you and your family from carbon monoxide poisoning. Alway use and maintain fuel-burning equipment and appliances correctly.
Signs of carbon monoxide:
- stuffy or stale air;
- more condensation than usual on your windows;
- soot build up around a fireplace, chimney, or other fuel-burning equipment;
- fuel-burning equipment has a back-draft (flame flares up when a window or door opens and adds air);
- a pilot light keeps going out.
CO poisoning symptoms
CO poisoning symptoms are like the flu. During flu season, many cases of CO poisoning may be left unreported and untreated.
If you have these symptoms, or the symptoms go away when you leave the building, call 911 or your local emergency services immediately.
|Exposure level||Symptoms and effects|
|Low||Light headache, shortage of breath during moderate physical activity|
|High||Severe headache, dizziness, nausea, vomiting, mental confusion, weakness, vision and hearing impairment, collapse or fainting during physical activity, loss of muscle control, drowsiness|
|Extreme||Unconsciousness, brain damage, death|

Have a qualified heating dealer:
- check and clean your heating system regularly;

- assess the need for a fresh air intake duct for wood-burning fireplaces or stoves.
- regularly test your CO alarms;
- keep your indoor and outdoor vents and chimneys clear of debris, snow, and ice;
- keep the area around your furnace clutter-free for proper air circulation;
- regularly check all natural gas appliances have a blue flame (a yellow flame may be a sign of CO);
- never idle a vehicle or run gas-powered equipment (for example, mower, snow blower, trimmer, generator) in your attached garage, even with the overhead door open;
- never use portable fuel-burning equipment (for example, generator, patio heater, barbecue, etc.) inside your home or garage.
