How this RV system works
Carbon monoxide (CO) is colourless and odourless. Faulty exhaust, blocked vents, engines or generators near windows, and fuel-burning equipment can create life-threatening exposure.
Before you begin
Find the model number and instructions for the exact appliance fitted to your RV. A travel trailer, fifth-wheel and motorhome may have very different controls, ventilation and power supplies. Check campground rules before running generators or fuel-burning equipment.
Step-by-step owner checks
- Install and maintain CO alarms suitable for RV use in the locations specified by their manufacturers.
- Check alarm expiry, power and test procedure before every trip.
- Keep generator and vehicle exhaust well away from openings and neighbouring RVs.
- Never idle an engine or run a generator in an enclosed garage, under an awning enclosure or near air intakes.
- If an alarm sounds or occupants develop headache, dizziness or nausea, move everyone into fresh air and call emergency services.
Common symptoms and troubleshooting
| Symptom | Possible cause | Safer next step |
|---|---|---|
| CO alarm sounds | Possible dangerous CO exposure | Evacuate immediately and seek emergency help |
| Headache or nausea indoors | Potential CO poisoning | Move outside and seek urgent medical assessment |
| Soot near exhaust | Combustion or venting fault | Stop appliance and obtain professional service |
Canadian weather and regulations
Snow accumulation can obstruct furnace or generator exhaust in Canadian winter conditions; inspect vents from a safe location after snowfall.
Propane equipment installation, inspection and repair requirements can vary by province and territory. Check with the appropriate local safety authority and use a properly qualified service provider. Winter campsite availability, electrical hookups and fuel access also vary.
Preventive maintenance
Replace alarms by expiry date and service fuel-burning equipment regularly.
Record inspection dates, fault codes and any repairs in your RV maintenance log. Keep combustion-air openings, appliance exhausts and detectors unobstructed, and check all relevant alarm expiry dates.
Reliable Canadian and safety references
- Health Canada: carbon monoxide and indoor air
- Natural Resources Canada: energy efficiency

Alarms and Canadian winters
Never run propane heaters or generators in ways that vent into the cabin. Test CO alarms regularly, replace them on schedule and keep windows slightly open when using unvented sources if the manufacturer permits.
Alarm checklist
- Look for CSA or ULC marks on alarms.
- Test alarms monthly and note the expiry date.
- Place alarms where you sleep.
- Never use a cooking appliance or outdoor heater to heat the cabin.
- Know the symptoms: headache, dizziness, nausea.
What should I do if the alarm sounds?
Move everyone outside into fresh air, call emergency services and do not re-enter until it has been cleared.
