The carbon monoxide poisoning is one of the biggest hazards of using camping stoves in a tent. Cooking anything in a camping tent can produce more carbon monoxide. Carbon monoxide (CO) should not be confused with carbon dioxide (CO2) carbon monoxide is a deadly by-product of incomplete combustion of fuel, usually produced in part by tent furnaces. This gas has a high affinity for your blood-cell hemoglobin, so it binds to them rather than to oxygen. Since there is no oxygen in the blood, there is no brain activity, which leads to a rapid loss of consciousness and eventual death. The effect is even worse when you pack several people in a tent and zip them up. This means lower oxygen levels. If you climb a mountain above sea level, it means your oxygen level has dropped. The worst part about carbon monoxide poisoning is that it's odorless and asymptomatic. Or rather, the symptoms of CO poisoning are similar to the dehydration/hunger that many campers typically experience while camping.
Light your tent
Inhaling toxic carbon monoxide isn't the only threat to personal space fires. You also need to be more concerned about fire hazards. Consider how flammable your tent fabric is, and whether tripping over a can could cause your tent to catch fire. This may sound far-fetched, but the possibility of a fire is greater than you think. I once had trouble connecting my canister fuel to the ring cooker and didn't know it. There was a leak that ignited flames up to 2 feet high. Luckily, it was hot and I was cooking outside. Now, if I was on the porch or under the porch, it would probably catch fire. I know some tent materials, especially those with polyurethane waterproof tent materials, is to use the stove flame retardant materials. Even so, they usually have a plastic element that melts easily when exposed to heat.
Severe Burns
I don't usually care about carbon, because ventilation solves this problem. In my books, however, self-burning is usually the biggest threat. I'm a bit clumsy and always find myself knocking things over, especially in limited space. In small enclosed spaces like tents, it's easy to knock over my stove, splash boiling water or gravy and burn my skin. In addition, camping stoves may tip over, burn you and catch fire horizontally on the ground.
The smell of food attracts animals
If you're camping in Bear Country, you should practice bear control everywhere. I usually follow the rule of not cooking where I sleep to protect myself. Bears with Glock 20 usually work to my advantage, but I sleep better when I'm cooking outside the tent, knowing that the main smell is the hiker's fear and not the meatballs! Cooking outside the tent means you don't have to sleep with a bear, raccoon or other animal sniffing around..
