Carbon Monoxide Awareness
Too many people in B.C. die, or become seriously ill, because of carbon monoxide (CO) poisoning. While the effects of CO poisoning can be devastating, they can be prevented. The best things to do is have all fuel-burning appliances inspected by a licensed contractor every year and install a carbon monoxide alarm that signals an alert when the gas is present.
Awareness campaign resources
The Office of the Fire Commissioner wants to make it easier for fire departments and fire and life safety educators to host a local Carbon Monoxide Awareness campaign during Carbon Monoxide Awareness Week (Nov 1 to 7) or at any time of year.
Use the digital resources below on your social media channels or website, or conduct a door-to-door Home Safety Program by visiting residents and discussing prevention tips and checking for working carbon monoxide alarms.
Home Safety Program and community resources
A door-to-door campaign is a great way for fire departments to get out in the community to make sure people have CO alarms in their homes. Leave a door hanger behind if the resident isn’t home. Order free printed door hangers that include CO safety and prevention tips and room for you to add your department’s contact information.
Copy and paste these social media posts in to your own channels as is, or customize them to meet your needs.

Carbon monoxide – or CO – is known as the “silent killer” because it is an invisible, tasteless and odourless gas that can be deadly. CO is NOT natural gas – natural gas has a harmless chemical called mercaptan added to it to make it smell like rotten eggs. www.COsafety.tips
Ensure all fuel-burning appliances, chimneys and vents in your home are cleaned and inspected annually to help prevent the build up of carbon monoxide. Visit www.technicalsafetybc.ca to find a licensed contractor near you.
Prevent carbon monoxide poisoning and NEVER use BBQs or portable fuel-burning generators indoors! www.COsafety.tips
Your carbon monoxide alarm sounds different than your smoke alarm. Test BOTH alarms monthly and make sure everyone in your home knows the difference between the two sounds. #TestItTuesday www.COsafety.tips

- Carbon monoxide (CO) is a toxic gas that you can’t see or smell, which can be harmful if you are exposed to it. It's produced when fuels are burned incompletely, including natural gas, propane, wood, tobacco and gasoline.
Carbon monoxide (CO) is a poison gas that is a by-product of burning gasoline, natural gas, wood, oil, kerosene or propane. It can come from:
- Furnaces, gas range/stove, gas clothes dryer, water heater, portable fuel-burning space heaters, fireplaces, generators and wood-burning stoves;
- Portable heaters and stoves, such as those used for camping;
- Vehicles, generators and other combustion engines running in an attached garage or other enclosed space;
- Blocked chimney or flue;
- Cracked or loose furnace exchanger;
- Second-hand smoke;
- Back drafting and changes in air pressure; or
- BBQs and grills.
- Carbon monoxide (CO) is a colorless, odorless and tasteless poison gas that can be fatal when inhaled, which is why it’s sometimes called the "invisible killer". It reduces oxygenation in the body by displacing oxygen absorption at a cellular level.
- Unlike many other toxins and poisons, CO doesn’t irritate your body or cause pain—meaning there’s often no warning or danger signs of its presence.
- Initial symptoms are similar to the flu without a fever and can include dizziness, severe headaches, nausea/vomiting, sleepiness, blurred vision, fatigue/weakness, disorientation/confusion and loss of consciousness.
- CO poisoning can be particularly dangerous for people who are sleeping or intoxicated.
- People may end up with irreversible brain damage, or even die, before anyone realizes there's a problem.
Ensure any fuel-burning appliances—and the supporting ventilation systems—are installed by a licensed contractor. Be sure to operate them according to the manufacturer's instructions.
Keep chimneys clear of animal nests, leaves and residue to ensure proper venting. Do not block or seal shut exhaust flues or ducts used by water heaters, ranges and clothes dryers.

Every fuel-burning heating appliance—new or old—has the potential to generate dangerous levels of CO without any obvious signs of failure.
Have all fuel-burning heating appliances cleaned and inspected annually.

Install CO Alarms
Install at least one battery-powered carbon monoxide (CO) alarm or AC-powered unit with battery backup on each level of your home and near sleeping areas.
Test and check all CO alarms in your home twice a year. Replace CO alarms according to manufacturers’ instructions.
Always use portable generators, BBQs, camp stoves or other similar devices away from doors, windows, vents and other openings. Never use them indoors, including inside a garage (even if the doors are open) or other enclosed or partially enclosed area.
Never use a gas range, stove or oven to heat the home.
Never leave your car idling in a closed garage. If your vehicle has an automatic engine starter, check to make sure your vehicle is off it is in the garage.
Never use fuel-powered appliances or tools in enclosed, attached areas such as garages or porches.
- Carbon monoxide (CO) inhibits the blood's capacity to carry oxygen and can cause health problems before you even notice that it's present.
- At low levels, effects include flu-like symptoms, such as tiredness, headaches, shortness of breath and impaired motor functions.
- At high levels, or if you are exposed to low levels for long periods of time, you can experience dizziness, chest pain, poor vision and difficulty thinking.
- At very high levels, it can cause convulsions, coma and death.
- If you suspect CO poisoning, get into fresh air immediately and call 9-1-1 or your local emergency number. Once you're at the hospital, treatment may involve:
- Breathing pure oxygen through a mask placed over your nose and mouth. This helps oxygen reach your organs and tissues. If you can't breathe on your own, a machine (ventilator) may be used.
- In many cases, hyperbaric oxygen therapy is recommended. This therapy involves breathing pure oxygen in a chamber in which the air pressure is about two to three times higher than normal. This speeds the replacement of carbon monoxide with oxygen in your blood.
- Every home with at least one fuel-burning appliance/heater, attached garage or fireplace should have a carbon monoxide (CO) alarm.
- Ideally, an alarm should be installed on every level of the home and outside each sleeping area, and placed at least 15 feet away from fuel-burning appliances. If the home has only one CO alarm, it should be installed in the main bedroom or in the hallway outside of the sleeping area.
- Do not install a CO alarm near windows or vents, bathrooms, heating or fuel-burning appliances, smoke alarms (unless a combination alarm) or at the peak of a vaulted ceiling.
- Make sure nothing is covering or obstructing the unit.
- Test the CO alarm at least once a month by pressing the test/reset button.
- Every month, unplug the unit and vacuum with a soft-brush attachment or wipe with a clean, dry cloth to remove accumulated dust.
- Replace batteries and the entire unit according to manufacturer's instructions.
- If anyone is experiencing symptoms, leave your home immediately and move to fresh air. Do not try to locate the source of carbon monoxide. Once outside, call 9-1-1 or your local emergency number from a mobile phone or neighbour’s house.
- If no one is experiencing symptoms, go outside and call the fire department or a qualified technician from a mobile phone or neighbor's home to have the problem inspected.
- If you are unable to leave the home to call for help, open the doors and windows and turn off all possible sources while you are waiting for assistance to arrive.
- Return to your home only after the problem has been fixed by a professional.
- Under no circumstance should an alarm be ignored!
- Mercaptan is added to natural gas to make leaks easier to detect and smells like rotten eggs. A natural gas leak is NOT the same as accumulation of carbon monoxide.
- Look for carbon monoxide (CO) alarm models with the seal of an approved certification agency such as the Canadian Gas Association or the Canadian Standards Association and the replacement date and warranty period clearly listed.
- Have heating systems, vents, chimneys and/or flues inspected every year by a licensed contractor. Regularly examine vents and chimneys for improper connections, visible rust and stains.
- Install and operate fuel-burning appliances according to the manufacturer's instructions.
- Always use portable generators, BBQs, camp stoves or other similar devices away from doors, windows, vents and other openings. Never use them indoors, including inside a garage (even if the doors are open) or other enclosed or partially enclosed area, like a tent.
- Never use a gas range, stove or oven to heat a home.
- Never leave your car idling in a closed garage. If your vehicle has an automatic engine starter, check to make sure your vehicle is off it is in the garage.
- Never use fuel-powered appliances or tools in enclosed, attached areas, such as garages or porches.
