Storing Butane on an Outdoor Adventure

By Dave Sabot

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.

These lighters are powered by gaseous butane which is aerosolized by the jet when the fuel release mechanism is tripped. This fuel is generally safe but one needs to make certain they follow basic safety precautions when carrying it around on a camping, fishing or hunting trip.

If the can of butane is exposed to heat beyond the maximum temperature indicated on the warning label, the liquid will expand. This will increase the pressure on the can and, in extreme cases, can result in a rupture. Most of these cans are designed so that the valve will rupture first but this will still result in a cloud of butane gas being released into the air. Butane combusts very quickly and, if there is open fire or sparks nearby, it is almost certain to create a fireball.

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.
