Try to do any fuel filling out in the open. White gas used as a primer flares up violently while solid fuel burns predictably. Avoid wrapping the stove in any kind of insulation. Use only insulation under the base of the stove. If the tank becomes so hot it can't be touched, turn off the stove and let it cool.
Some stoves have a safety release valve in the cap.
If too much pressure builds up gas will escape out of the safety release. Usually the escaping gas will ignite throwing flame away from the stove. Keep the cap pointed away from you and outside the tent door. Fill the tank before starting to cook. If you have to fill the tank while cooking, allow it to cool off before fueling.
