Liquefied Petroleum Gas (LPG) is the generic name for mixtures of hydrocarbons (mainly propane and butane). When these mixtures
are lightly compressed (approx. 800 kPa or 120 psi), they change from a gaseous state to a liquid.
LPG burns readily in air and has energy content similar to petrol, which makes it an excellent fuel for heating, cooking and for
LPG is colorless, odorless and heavier than air. A sulphur based chemical (ethyl mercaptan) is added to give it a smell like rotten
cabbage, so that even a very small leak can be easily detected.
