Carbon monoxide Carbon monoxide (CO) is an odourless and colourless—but poisonous—gas. Since you can’t see, feel or taste it, CO can harm you and your family before even know it is there. Even low exposure to CO can cause serious health problems. All fuels can produce CO when they burn: propane, heating oil, natural gas, kerosene, gasoline, wood, coal, diesel, etc.
Equipment and vehicles that burn one of these fuels therefore produce carbon monoxide. When these vehicles and equipment aren’t running well, are used improperly (i.e., in a poorly ventilated area), or are not maintained, the amount of carbon monoxide produced can be hazardous to your health and even life-threatening.
Symptoms
Mild poisoning can cause:
- headaches
- dizziness
- nausea
- vomiting
- fatigue
More serious exposure can cause:
- fainting
- convulsions
- coma and even death
Protect yourself by taking precautions
- Have your combustion appliances and ventilation in the places where they are used checked.
- The only way to detect the presence of carbon monoxide is to
install a carbon monoxide detector. - Have the condition of your chimney and your furnace ductwork checked.

Stay safe from carbon monoxide on vacation
Whether you’re at the cottage, on a fishing or hunting trip, off in the camper, or tenting in the woods, make sure you have a carbon monoxide detector with batteries and check that the detector is working.
Make sure that you use fuel-burning appliances correctly and that you properly maintain them.
