Can You Use a Camping Stove Inside a Tent? No — and It's Not a Close Call

Why "the door is open" fails

Modern tents have integral groundsheets and limited air exchange. A single open door creates a high vent, but without a low vent, there's no through-flow. CO — heavier than the air it mixes into near the floor — accumulates around the sleeper.

The "minutes" figure

Devon & Somerset Fire and Rescue note that modern tents can reach fatal CO levels "in a matter of minutes." This isn't a slow, cumulative risk you can monitor — by the time symptoms appear, exposure may already be dangerous.

Even a faulty stove outdoors

WorkSafe NZ adds a critical caveat: a faulty appliance can emit carbon monoxide even in well-ventilated areas. The risk isn't only about the tent — it's also about equipment condition. Both variables have to be controlled.

Complete vs. incomplete combustion

When hydrocarbon fuels burn with enough oxygen, they produce carbon dioxide (CO₂) and water vapour — both harmless in a ventilated space. When oxygen is limited, combustion is incomplete and carbon monoxide (CO) forms instead.

Inside a tent, oxygen is consumed by the flame and not replenished fast enough. The result is a steadily rising CO concentration with no visible sign.

The "cold flame" problem

WorkSafe NZ identifies two triggers that cause CO even outdoors: (1) a pot placed directly on the burner head instead of on the trivet, which cools the flame; and (2) a pot too large for the stove, which also cools the flame.

Practical rule: give the flame room to burn — it should just touch the bottom of the pot. Use the trivet, match the pot to the burner.

Cheshire Fire & Rescue (UK)

"Never use fuel-burning devices (e.g. disposable barbecues, camping stoves, camping heaters, lanterns, and charcoal grills) inside a tent."

"Opening tent flaps, doors, or windows is insufficient to prevent build-up of CO concentrations from these devices."

Building and Energy, WA (Australia)

"Portable gas appliances should never be used inside tents, caravans, campervans or other enclosed areas, including indoors at home, even if the doors or windows are open."

"Carbon monoxide… can build up and, worryingly, because this potentially lethal gas is colourless and odourless, you may not even be aware you've been exposed until it's too late."

WorkSafe New Zealand

"Never use in confined spaces such as small tents. If inside, make sure there's plenty of space and ventilation… openings at high and low levels."

"A faulty appliance may also emit carbon monoxide even in well ventilated areas."

Devon & Somerset Fire & Rescue (UK)

"Do not use BBQs or stoves inside your tent or caravan. This includes the awning or entrance. The carbon monoxide they produce can kill, and the heat they produce will set the tent on fire."

"A fire can destroy a tent in 60 seconds."

Early symptoms

• Headache
• Dizziness
• Weakness
• Nausea
• Confusion

If symptoms appear

Move to fresh air immediately. Seek medical attention without delay. Monitor the affected person constantly until help arrives. Be prepared to start CPR if necessary.

Note: the victim may not recognise their own symptoms due to impaired judgement.

Why detectors don't solve it

Devon & Somerset Fire Service notes that CO detectors are "not designed for the conditions found in a tent or awning." They're useful at home, in caravans, and motorhomes — but should not be relied on in a tent.

The MSR PocketRocket 2

$36.89 ·4.6 stars ·4,288 reviews. Weighs just 2.6 oz (stove only) and boils 1 L in 3.5 minutes — the best weight-to-performance ratio in our stove comparison.

Because it's so light and fast, cooking outside costs you almost nothing: set it up on a flat rock 6+ metres from the tent, boil water in under four minutes, then carry your food inside.

The safe routine

1. Pitch the tent, then set up the stove at least 6 m away (fire-service minimum), on a flat, non-flammable surface.
2. Use the trivet and a correctly sized pot — the flame should just touch the pot base.
3. Boil/cook outside, in open air.
4. Turn the stove off fully before leaving it.
5. Carry the food inside and eat in the tent.
6. Never bring the lit stove, or a still-hot one, inside.

What about a stove designed for tents?

Some tents are sold with dedicated, vented stove jacks and flues (typically canvas wall tents and hot tents). Those systems are engineered for indoor combustion with a chimney to exhaust CO. A standard backpacking stove — including the PocketRocket 2 — has no flue and must never be used inside a sealed tent.

The takeaway

The cost of cooking outside is a few minutes of cold. The cost of cooking inside can be a life. There is no convenience worth that trade — and with a 2.6 oz stove, there's no real inconvenience either.

Is a propane or butane stove safer inside a tent than a wood fire?

No. All fuel-burning devices produce carbon monoxide when oxygen is limited. Propane, butane, isobutane, charcoal, and wood all carry the same indoor warning from fire services. The fuel type doesn't change the chemistry.

Can I use a stove in a tent vestibule or awning?

No. Devon & Somerset Fire Service explicitly includes "the awning or entrance" in its prohibition. A vestibule is still an enclosed space with limited air exchange.

How far from the tent should I cook?

Fire services recommend at least six metres (about 20 feet) between tents and any cooking device or vehicle. This protects against both CO drift and fire spread.

Are there any safe indoor camping stoves?

Only engineered systems with a proper flue or chimney that exhausts combustion gases outside — for example, a wall tent with a dedicated stove jack and pipe. A standard portable backpacking stove is not one of these.
