What You'll Learn
Candle lanterns and carbon monoxide poisoning risk
Candle lanterns are popular among campers for their portability, lightweight design, and ease of use. They also produce heat, which can make a tent warmer. However, it is important to be aware of the risks associated with their use, particularly the risk of carbon monoxide poisoning.
Any combustion process yields carbon monoxide, a colourless, odourless, and deadly gas. Incomplete combustion, indicated by a candle's yellow flame, produces carbon monoxide. Therefore, candle lanterns can emit carbon monoxide and pose a poisoning risk if used in an enclosed space without proper ventilation.
The dangers of carbon monoxide poisoning from candle lanterns are similar to those of gas lanterns. Gas lanterns, which burn fuels like propane, white gas, or kerosene, also emit carbon monoxide and should be used outdoors in well-ventilated areas. The fumes produced by a lantern are comparable to those released by a running car in a closed garage, underscoring the seriousness of the hazard.
To mitigate the risk of carbon monoxide poisoning when using a candle lantern, adequate ventilation is crucial. When using a candle lantern in a tent, ensure there is sufficient fresh air circulation by keeping the tent well-ventilated. Additionally, be cautious of the other hazards associated with open flames, such as the risk of fire and the potential to exhaust the oxygen supply in an enclosed space.
While candle lanterns offer convenience and warmth, users should be vigilant about the potential dangers. By taking precautions, such as proper ventilation and flame management, individuals can reduce the risk of carbon monoxide poisoning and enjoy the benefits of candle lanterns safely.

Incomplete combustion and carbon monoxide
Burning a candle inside a lantern is not as safe as using a flashlight or a battery-powered lantern. While modern tents are flame-resistant, there is always a risk of the lantern getting bumped and damaging the tent or other equipment.
Furthermore, any combustion process yields carbon monoxide, an invisible and odourless gas. Incomplete combustion of carbon-containing fuels, such as natural gas, gasoline, or wood, produces carbon monoxide. This occurs due to a shortage of oxygen in the combustion chamber, low temperatures, or short residence times. The presence of carbon monoxide indicates a poor combustion process.
Carbon monoxide is harmful because it binds to haemoglobin in the blood, reducing the blood's ability to carry oxygen. This interference with oxygen delivery to the body's organs can cause adverse health effects, especially for unborn babies, infants, elderly people, and those with cardiovascular disease, anaemia, or a history of heart or respiratory issues.
To reduce the risk of carbon monoxide poisoning when using candle lanterns, ensure proper ventilation in the tent and do not rely solely on the candle for warmth. It is recommended to use citronella candles, as they are generally safe, clean, and non-toxic.

Ventilation and carbon monoxide buildup
Candle lanterns are an excellent source of light and can also provide some warmth when you're out camping. However, it's important to be mindful of the potential dangers associated with their use, particularly the risk of carbon monoxide (CO) buildup.
Carbon monoxide is a colourless, odourless, and deadly gas formed when fuels don't burn completely. It can be released from various sources, including combustion appliances, charcoal grills, camp stoves, and fuel-burning lanterns. Inhaling carbon monoxide is extremely harmful as it displaces oxygen in the body, leading to poisoning and even death. The symptoms of carbon monoxide poisoning are often flu-like, making it challenging to identify without a CO detector.
When using candle lanterns, adequate ventilation is crucial to prevent carbon monoxide buildup. Ensure your tent has sufficient ventilation by keeping the lantern away from the tent walls and hanging it or setting it on the floor. Additionally, modern tents are designed to pass flame-resistance tests, reducing the risk of fire.
To further enhance ventilation and prevent carbon monoxide buildup, consider the following:
- Use hot water bottles, heating rocks, electric blankets, or portable electric radiators for warmth instead of candles.
- Insulate your tent to retain heat and reduce the need for additional heat sources.
- Maintain a safe distance from the exhaust areas of boats when boating, and be mindful of exhaust fumes from neighbouring boats.
- Regularly inspect and maintain heating equipment in cabins and ice houses, and ensure proper ventilation by cracking a window.
- Install a CO alarm in your home, tent, RV, cabin, or boat to detect dangerous CO levels.
- Keep vents and chimneys clear of snow, leaves, and debris to ensure proper airflow and prevent CO buildup.
- Have a qualified professional inspect your appliances and ventilation systems regularly to ensure safe functioning and identify any potential CO hazards.
By following these precautions and maintaining adequate ventilation, you can safely enjoy the benefits of candle lanterns while minimising the risk of carbon monoxide buildup and poisoning.

Carbon monoxide poisoning symptoms
Candle lanterns are a potential source of carbon monoxide, a colorless, odorless, and tasteless gas made when fuel (such as wood, gasoline, coal, natural gas, or kerosene) burns. Any combustion, including candles, yields carbon monoxide, so adequate ventilation is crucial.
Carbon monoxide (CO) poisoning occurs when CO fumes are inhaled, preventing the body from utilizing oxygen properly. This can have severe consequences for the brain, heart, and other organs. People with pre-existing health issues, such as heart and lung disease, are particularly vulnerable, along with infants, children, pregnant individuals, and older adults. The most common sources of CO poisoning are unvented space heaters, especially during winter in cold climates.
CO poisoning symptoms often mimic the flu or food poisoning, including headache, dizziness, weakness, nausea, vomiting, rapid heartbeat, shortness of breath, seizures, chest pain, disorientation, and loss of consciousness. It is crucial to act quickly if you suspect CO poisoning. Move to an area with fresh air, turn off the CO source if it can be done safely, and call emergency services. A blood test can detect CO in the blood, and a physical exam may reveal changes in mental status.
To prevent CO poisoning, ensure proper ventilation in areas where fuel is burned, such as when using lanterns, heaters, or stoves. Regularly inspect and maintain fuel-burning appliances, fireplaces, and furnaces. Install battery backup CO detectors in your home to alert you to rising CO levels. Additionally, never leave vehicles running in enclosed spaces, and keep generators outdoors and away from windows, doors, and vents.

Carbon monoxide detection and treatment
Carbon monoxide is a colourless, odourless, and poisonous gas that is a byproduct of burning carbon fuel. It is often referred to as the "silent killer" because it is virtually undetectable by humans. Candle lanterns are an open flame and any combustion yields carbon monoxide, so caution and ventilation are necessary when using them.
Carbon Monoxide Detection
Carbon monoxide detectors are devices that detect the presence of carbon monoxide gas to prevent carbon monoxide poisoning. They are designed to measure the concentration of carbon monoxide in the air (in parts per million, or PPM) and sound an alarm if the levels become dangerous. The primary purpose of CO detectors is to warn occupants of an enclosed space of a dangerous level of carbon monoxide. The alarm should sound within 60 minutes if the concentration rises to 70 PPM, within 10 minutes at 150 PPM, in 4 minutes at 400 PPM, and immediately at 500 PPM or greater.
There are several types of detectors available, each employing a different method to gauge carbon monoxide levels. The four main types of sensors are biomimetic sensors, metal oxide semiconductor sensors, electrochemical sensors, and coloured chemical sensors. The National Fire Protection Association (NFPA) recommends installing detectors per the manufacturer’s instructions in a central location outside each room where people sleep and on every floor of the home. Local laws, codes, or standards may have additional requirements.
Carbon Monoxide Treatment
Carbon monoxide sends up to 50,000 people to the emergency room every year in the US alone, and claims over 430 lives. Even small doses of carbon monoxide can cause permanent damage or death. If you suspect carbon monoxide poisoning, it is important to act quickly and move to a carbon monoxide-free environment. Symptoms of carbon monoxide poisoning include nausea, headache, and loss of consciousness.
