Whether at campsite or backpacking, safety with pressurized gas stoves is very important. All scouts must be familiar with their campstove fuel:
Choose a stove with a self igniter so as to save using matches.
Keep and use the plastic cover that comes with all fuel canisters. It will help keep the valve on top clean.
Realize that all pressurized fuel canisters have the same Lindal valve on top, making all stoves and canisters interchangable.
Before screwing the stove onto the canister, make sure that the stove valve is closed, and that both stove seals and canister top are free of debris.
Choose a stable area to place the stove since you do not want your cooking pot to tip over and spill your meal.
Keep fuel canisters out of the direct sun and fires as they can explode.
If it is cold out, put the canister inside your jacket to warm it up before cooking.
If the stove seems to slow down, it may be due to the fuel inside becoming cooler as it vaporizes. Sitting the stove in a pan of water can add heat to the fuel and help it to burn better.
Make sure to let the stove cool off before touching it.Once spent, the fuel canister should be depressurized and punctured with a Jetboil CrunchIt tool (costs about $5) and then sent for recycling.
The only reliable way to accurately determine how much fuel is left in a partially used canister is to weigh it. Obtain a food scale that will weigh in grams at a local department store (in the cooking utensil section, usually around $15 to $20). Use this chart to determine how much fuel is left.
