Portable Carbon Monoxide Detectors for Camping: What to Know

Camping can mean cooking, heating or lighting with fuel-burning equipment. These activities can produce carbon monoxide (CO), a poisonous gas that has no smell, colour or taste. In an enclosed or partly enclosed space, such as a tent, awning or campervan, CO can build up quickly and become dangerous.

A suitable portable CO alarm can provide an important warning, but it is not a substitute for safe use of camping equipment. Here’s how to choose and use one wisely.

Why take a CO alarm camping?

Carbon monoxide is produced when fuels such as gas, petrol, wood, charcoal and paraffin do not burn completely. Potential sources at a campsite include portable heaters, camping stoves, lanterns, barbecues and generators.

Using these appliances in or near a tent, awning or vehicle can allow fumes to collect. Even a well-ventilated shelter should not be treated as safe for equipment that is meant to be used outdoors.

Choosing a portable carbon monoxide detector

For camping, choose a CO alarm designed for the environment in which you plan to use it. Check the packaging and manufacturer’s instructions to make sure it is suitable for camping, caravans or other leisure use. In the UK, alarms intended for recreational vehicles may refer to BS EN 50291-2. A general-purpose gas meter or CO monitor is not necessarily a certified life-safety alarm.

• Check the standard: Look for the relevant British or European standard and clear information about the alarm’s intended use.
• Read the instructions: Follow the guidance on placement, operating temperature, moisture, cleaning and storage.
• Check the power source: Confirm the battery type and whether the alarm has a low-battery warning.
• Check its age: CO alarms have a limited working life. Check the expiry or replacement date and replace the unit when required.
• Consider portability: A compact alarm with a secure stand or mounting option can be easier to position in a tent or vehicle.

Where should you place it?

Use the placement instructions supplied with the alarm. They may differ between models, and the best position can depend on whether it is being used in a tent, caravan or campervan. Keep it away from direct rain, condensation, cooking splashes and strong draughts unless the manufacturer says otherwise. Do not cover it or place it where luggage or bedding could block it.

Test the alarm before each trip, and check its batteries and condition regularly. A test button usually checks the alarm’s electronic functions; it does not prove that the surrounding air is free from carbon monoxide.

Use camping equipment safely

• Never use a barbecue, charcoal grill or disposable barbecue inside a tent, awning, caravan or campervan—even after the flames have gone out.
• Do not cook inside a tent unless the equipment is specifically designed for that use and the manufacturer’s instructions permit it. Whenever possible, cook outdoors, well away from your shelter.
• Never use a generator, camping stove or outdoor heater inside a tent or awning.
• Keep generators outdoors and well away from doors, windows, vents and other openings. Follow the manufacturer’s safety distances.
• Do not use fuel-burning appliances for heating while sleeping unless they are specifically designed and installed for that purpose, and their instructions allow it.
• Maintain and operate appliances exactly as the manufacturer directs. Do not use damaged or poorly maintained equipment.

A CO alarm should be treated as an extra layer of protection—not permission to use an appliance in an unsafe place.

What to do if the alarm sounds

If the alarm sounds, or anyone develops symptoms that could be caused by carbon monoxide, get everyone outside into fresh air immediately. Symptoms can include headache, dizziness, nausea, weakness, confusion and shortness of breath. They may be mistaken for flu or tiredness.

Do not go back inside to investigate or retrieve belongings. Once outside, call 999 if anyone is seriously unwell or struggling to breathe. Do not use the appliance again until it has been checked by a qualified professional.

A simple safety check before you go

Before setting off, check that your CO alarm is suitable for your camping setup, in date, powered and working. Pack it where it will not be crushed or exposed to water, and take a moment to review the instructions. Most importantly, keep fuel-burning equipment out of enclosed spaces and follow the safety guidance for every appliance.

Do I need a portable carbon monoxide detector when camping?

A portable carbon monoxide (CO) alarm is strongly recommended when camping, particularly in a caravan, campervan or other enclosed space where fuel-burning appliances are used. Choose an alarm suitable for camping and follow its instructions for placement and use. It is an extra safeguard, not a substitute for safe practice: never use a barbecue, generator or outdoor cooking appliance inside a tent, awning or vehicle, and ensure equipment is used as directed.

Can I use a standard household carbon monoxide alarm in a tent or campervan?

A standard household carbon monoxide alarm may not be suitable for camping, as it may not be designed for the temperature, damp or vibration a tent or campervan can experience. Check the manufacturer’s instructions and choose an alarm specifically approved for your setting; for caravans and motorhomes, look for one compliant with BS EN 50291-2. Never use a barbecue, stove or other outdoor-only appliance inside a tent or vehicle, even if you have an alarm.

Where should I place a carbon monoxide detector when camping?

Place your portable carbon monoxide detector where the manufacturer recommends for your type of shelter, whether that is a tent, caravan or campervan, as guidance can vary between models. Keep it unobstructed and away from rain, condensation, cooking splashes and strong draughts, and do not place it where bedding or luggage could cover it. Test the alarm before your trip and follow its instructions for use. A detector is an extra safeguard, not a reason to use fuel-burning appliances inside a tent or other enclosed space.

Can I use a camping stove or heater inside a tent if I have a carbon monoxide alarm?

No. A carbon monoxide alarm does not make it safe to use a camping stove or fuel-burning heater inside a tent: carbon monoxide can build up quickly, and there is also a serious fire risk. Cook outdoors, well away from the tent, and only use a heater in an enclosed space if it is specifically designed for that purpose and the manufacturer’s instructions say it is safe. Treat the alarm as an extra safeguard, not a substitute for using equipment safely.

How do I test and maintain a portable carbon monoxide detector?

Test your portable carbon monoxide detector before each camping trip and at the intervals recommended by the manufacturer, using the test button as instructed. This checks the alarm’s electronic functions, but does not confirm that the sensor will detect carbon monoxide. Check the battery, expiry or replacement date, and inspect the unit for damage; keep it clean and dry, and store it as directed. Never test it with vehicle exhaust or by burning fuel nearby. Replace the detector when it reaches the end of its stated service life, and follow the manufacturer’s instructions for any maintenance.

How long does a portable carbon monoxide detector last?

A portable carbon monoxide detector typically lasts around five to ten years, but its lifespan depends on the model and sensor, so check the manufacturer’s instructions and the replacement date printed on the alarm. This is different from battery life: batteries may need replacing sooner, unless the unit has a sealed battery. Test the alarm before each camping trip and replace it immediately if it reaches its expiry date, gives an end-of-life warning or is damaged.

What should I do if my carbon monoxide detector sounds while I’m camping?

If your carbon monoxide detector sounds while you’re camping, get everyone outside into fresh air immediately and move well away from the tent, caravan or campervan. Do not stop to investigate, switch off appliances or collect belongings, and do not go back inside until it has been declared safe. Once outside, call 999 if anyone feels unwell, particularly if they have a headache, dizziness, nausea, confusion or difficulty breathing. Do not use the suspected appliance again until it has been checked by a qualified professional.
