What You'll Learn
Exhaust leaks from a vehicle engine or generator
Sources of exhaust leaks in campers can include the engine bay, the exhaust manifold, or the engine bay seal. These leaks can occur due to cracked or damaged exhaust pipes, loose or damaged connections, faulty gaskets and seals, or issues with the exhaust manifold. Older vehicles, vehicles with poorly maintained exhaust systems, or those with a compromised catalytic converter are particularly susceptible to CO leaks.
To prevent CO poisoning from exhaust leaks, it is crucial to regularly inspect and maintain your camper's exhaust system. This includes scheduling inspections by a qualified mechanic, cleaning the exhaust system, promptly replacing worn components, and keeping the engine well-tuned. Additionally, installing a CO detector specifically designed for vehicles can provide early warning of dangerous CO levels.
The effects of CO poisoning can range from dizziness, drowsiness, and headaches to more severe symptoms such as nausea, vomiting, and loss of consciousness. Prolonged exposure to high concentrations of CO can lead to brain damage or even death. Therefore, it is essential to take immediate action if you suspect a leak or experience any symptoms of CO poisoning. Move to fresh air, seek medical attention, and have a qualified technician inspect and repair your camper's exhaust system.
By being vigilant about maintenance, aware of the signs of a potential leak, and equipped with a CO detector, you can significantly reduce the risk of CO poisoning from exhaust leaks in your camper.

Faulty exhaust systems
A faulty exhaust system can cause a build-up of CO in several ways. One of the most common issues is a leak, which can cause CO to escape before it reaches the catalytic converter. The catalytic converter combines oxygen with CO to form carbon dioxide, a nontoxic gas. However, if there is a leak in the exhaust system, CO can enter the cabin of the camper through holes in the body, windows, doors, or the HVAC system. This is especially dangerous as CO is undetectable without an instrument, and even low concentrations can be harmful to health.
Another issue with faulty exhaust systems is corrosion or rust, which can cause holes to form in the exhaust pipe, muffler, catalytic converter, and exhaust manifold gasket. These holes can widen over time, allowing more CO to escape into the cabin. Cars that are driven infrequently or for shorter distances are at higher risk for rust, as water accumulates in the muffler and other exhaust system parts, leading to corrosion.
To prevent CO poisoning from a faulty exhaust system, it is important to have the system inspected regularly for signs of rust and to check the connections between parts. It is also recommended to get the exhaust system serviced annually, even after minor accidents, as crucial exhaust components may be damaged. Additionally, it is crucial to never run or warm up a camper with a faulty exhaust in an enclosed space, as lethal levels of CO can accumulate rapidly.
The effects of CO poisoning can range from tightness of the chest, dizziness, headaches, and shortness of breath, to more severe symptoms such as unconsciousness, brain damage, and even death. It is important to be able to recognize the signs of CO poisoning and to have a working carbon monoxide detector in the camper to alert you to dangerous levels of CO.

Inadequate ventilation
Cooking with Range Burners
Cooking with range burners without proper ventilation can cause a build-up of CO. It is important to always use the range fan and keep a window cracked open for fresh air when cooking. Under no circumstances should range burners or ovens be used to heat the camper.
Camping with Gas or Propane Stoves
Camping in tents with gas or propane stoves can be dangerous due to inadequate ventilation. Tents create enough of an enclosed space that the lack of proper ventilation can lead to a significant risk of CO poisoning. It is crucial to never use gas or propane stoves inside a tent.
Using Backup Generators
Gas-powered generators can cause a build-up of CO inside a camper or any enclosed space. It is important to place the generator away from the camper and direct its exhaust away from the camper and any neighbouring areas. Additionally, keep windows and vents closed if in close proximity to a running generator.
Space Heaters and Other Heating Appliances
Unvented space heaters are a common source of CO poisoning, especially during power outages in the summer months. It is crucial to only use fuel-burning space heaters in well-ventilated areas. Newer models of space heaters have safety features that shut them off when oxygen levels in the room drop, but older models may not have this feature. Electrical space heaters do not produce CO.
Campfires
Campfires can also lead to CO poisoning if campers or staff are sitting too close to the fire or directly in the path of smoke. It is important to maintain a safe distance from the fire and be mindful of the wind direction to avoid inhaling smoke and fumes.
To prevent CO poisoning, it is essential to have proper ventilation and maintain a constant flow of fresh air in enclosed spaces. Additionally, regular inspection and maintenance of equipment, generators, and appliances are crucial to identify any potential sources of CO leaks.
