There are three small, cheap devices every campervan should carry, because they can save your life while you sleep: a carbon monoxide (CO) detector, a gas detector and a smoke detector. In the enclosed space of a camper, with gas, combustion and electricity, the risks are real, and these detectors are your safety net. Here's an explanation of which ones you need and how to fit them.
Carbon monoxide (CO) detector: the most important one
Carbon monoxide is an odourless, colourless and deadly gas produced by any incomplete combustion (heating, cooking, a barbecue nearby, a generator). You can't smell it or see it: you fall asleep and don't wake up. Every year there are poisonings, some fatal, in enclosed spaces. A CO detector is essential in a campervan, especially if you have gas heating or a gas hob (see gas safety).
- Position it at the height recommended by the manufacturer (CO mixes with air), near the sleeping area.
- Check the battery and run the test periodically.
Gas detector
Detects leaks from gas cylinders (butane/propane). Unlike CO, gas from cylinders is heavier than air and settles low down, so the gas detector is fitted at low level (near the floor). A build-up of gas can cause an explosion; the detector gives you an early warning (see gas inspection).
Smoke detector
The classic fire detector: warns of smoke and fire, giving you time to react and get out. Cheap and essential. Fit it on the ceiling (smoke rises). Also keep a fire extinguisher within reach (see fire extinguisher in the camper).
Maintenance
- Run the test on each detector regularly.
- Change the batteries and act on low-battery warnings.
- Respect the expiry date: sensors (especially CO ones) expire; replace them when due.
- Don't block the camper's ventilation grilles: they're part of the safety system.
In summary
A CO detector (near the sleeping area), a gas detector (at low level) and a smoke detector (on the ceiling) are three cheap, essential devices that can save your life in a camper. The step you can take today: if you don't have them, fit at least a carbon monoxide detector near where you sleep (the most critical one) and a gas detector at low level, and test them regularly; it's one of the best safety investments you can make. Combine it with gas inspection.
