Are portable gas appliances really carbon monoxide (CO) producers, or is there a bit more to the story? In this video, I’m busting a common myth and explaining the facts behind gas combustion, carbon monoxide production, and the precautions you need to understand when using portable gas appliances.
With 40 years of experience working with natural gas and LPG as both a Gas Engineer and Gas Inspector, I think I know a thing or two about how gas appliances work, the products of combustion, and what happens when combustion doesn't go as it should.
🔥 How is carbon monoxide actually produced?
When natural gas or LPG burns, the carbon and hydrogen in the fuel react with oxygen in the air. Under suitable conditions, complete combustion produces carbon dioxide (CO₂) and water vapour.
However, when combustion is incomplete, some of the carbon is only partially oxidised, producing carbon monoxide (CO) instead of carbon dioxide. This can occur when there is insufficient oxygen or when other conditions interfere with proper combustion.
So, it's not quite as simple as saying that all portable gas appliances automatically produce dangerous levels of carbon monoxide just because they burn gas. The amount of CO produced depends on the combustion conditions and how the appliance operates. However, even an appliance that appears to be working normally can present a carbon monoxide risk in certain circumstances.
🏕️ Portable gas appliances in tents, caravans and motorhomes
Whether you're camping in a tent, touring in a caravan, travelling in a motorhome, or converting a vehicle into a microcamper, it's important to understand the risks associated with using flueless gas appliances in enclosed spaces.
I'll explain the importance of ventilation, how combustion works, why you should never ignore the manufacturer's instructions, and the precautions you need to consider when using portable gas appliances.
I'm not here to tell you that portable gas appliances should never be used. I'm here to explain the science, separate fact from fiction, and help you understand the potential dangers so you can make informed decisions.
🚨 Carbon monoxide alarms: Which type should you look for?
A carbon monoxide alarm is an important part of your safety arrangements, but it's essential to choose one suitable for the environment in which you intend to use it.
In this video, I explain the relevant British Standards to look for when buying a CO alarm for your camping or touring setup:
• BS EN 50291-1 – Carbon monoxide alarms for domestic premises.
• BS EN 50291-2 – Carbon monoxide alarms for recreational vehicles and similar applications, including boats.
Knowing what these standards cover can help you choose an appropriately certified alarm for your intended use.
Remember, carbon monoxide is colourless, odourless, and potentially fatal. You cannot see it, smell it, or taste it, so never rely on your senses to detect it. A CO alarm is not a substitute for adequate ventilation, correct appliance installation where applicable, or following the manufacturer's instructions.
A little disclaimer!
Just to be clear, I'm not endorsing or encouraging anyone to use flueless gas appliances inside tents, caravans, motorhomes, or other enclosed spaces where the manufacturer says they shouldn't be used. I'm simply explaining the facts about combustion, carbon monoxide, and gas safety, based on my 40 years of experience in the industry.
If you choose to use this type of appliance in an enclosed space against the manufacturer's recommendations, you do so at your own risk. Please don't take this video as permission to ignore the instructions or safety warnings. Your safety is far more important than keeping warm or cooking a meal!
