Many adventurous individuals who need windproof lighter have gravitated toward the many butane torch types on the market. These lighters do provide excellent and reliable service under adverse conditions. The flame can be directed, even when the lighter is inverted, which makes them useful for starting campfires and other tasks.
The first and foremost rule when storing butane is access. It needs to be kept away from children as it does present a hazard to little ones. This fuel is liquid in the can but quickly becomes a gas in the absence of sufficient pressure. Anyone rupturing one of these cans is going to find themselves momentarily in a cloud of flammable gas.
First and foremost, the butane must be kept away from high heat conditions. The canister will give the range of safe temperatures. Exceeding these temperatures by either storing the canister in an environment which is too hot or too cold can result in the canister rupturing. This, of course, will result in a cloud of butane being released. While the butane is liquid while in the can, this is entirely dependent upon the pressure in that environment. Absent this pressure, it quickly becomes a gas and, if open flame is nearby, can cause an explosion.
While butane which has been released from a can will not explode in the proper sense, it will create a fireball that is enough to cause severe burns. The valve on the tank can release the fuel if a wire or other device is used to trip the mechanism. This is far too tempting a thing to trust to children and there are ample opportunities for them to injure themselves with one of these gas canisters. Treat these canisters with no less seriousness than one would treat any other flammable fuel. They may be sold in the household goods section but they are dangerous if mistreated.
Butane fuel absolutely must be kept away from flames caused by lanterns or campfires. While it may not feel that hot standing a bit away from these devices, a can next to the fire is likely being heated way more than is advisable. Keep the can in one's backpack and safely distant from any source of heat. Though some individuals are tempted to do so, never toss a butane canister on a fire to see "what will happen". It will explode. This is not only dangerous, it is illegal in most camping areas and can cause a dangerous fire.
