Lpg

[ash-hôôle]

Liquid Petroleum Gas, or Propane, is commonly used as a fuel for forklifts, man lifts, certain types of heaters and lighting. When pressurized and/or chilled, the propane gas contained within a cylinder turns into a liquid state. A liquefied gas is much more "concentrated" than gas which is simply compressed. For example, one gallon of liquid propane will produce about 245-275 gallons of gas. The primary dangers created by LPG are fire/explosion, carbon monoxide poisoning, asphyxiation, and extreme cold.

If a gas is liquefied, the pressure can increase rapidly when the gas is heated. Heating can come about from purely natural sources, such as the sun. Under normal circumstances, a relief valve on the cylinder will release the gas in a controlled manner to prevent the cylinder from exploding due to over-pressurization. However, if the cylinder and valve are not properly maintained and/or the pressure build-up is very rapid, such as when the cylinder may be directly exposed to fire, a cylinder failure and subsequent explosion can occur.
