There are times when Scouters want to use a gimmick to light a campfire in a special way. If you do use fuel, I suggest a rag soaked with a bit of kerosene. Although kerosene vaporizes much more slowly than other gas fuels, take care and make sure participants stand well clear. We all hate to crawl into a damp tent and sleeping bag at night. For some people, the answer is to take a lit lantern into the tent with them.
Some people are pretty foolish.
Even when everyone is warm and alert, it's very easy to knock over a lantern in a tent. Most of us know that a two-man tent can melt or burn to ashes in 15 to 30 seconds. That's not enough time to think, let alone get out of your bag, find the door, unzip and get out. When the weather is damp, roll up your sleeping bag to keep it dry. Your body will warm it quickly once you crawl into it and you won't notice the damp air in your tent.
