LP GAS
General
LP gas (Liquefied Petroleum gas) is a mixture of
gases produced and sold commercially as a con­
venient fuel for heating and cooking appliances.
The main components of LP gas are Propane
(C3H8) and Butane (C4H10) and since Propane
accounts for the highest percentage (over 95%), LP
gas is often also called Propane. LP gas is highly
flammable and, as a result, can be explosive if ignit­
ed under certain conditions. The physical properties
of LP gas vary somewhat on actual composition.
The following table summarizes the main properties
of both Propane and Butane; LP gas will behave
more closely to Propane.
