Propane is a hydrocarbon (C3H8) and is
sometimes referred to as liqueed petroleum gas,
LP-gas orLPG.It is produced from both natural
gas processing and crude oil rening.The major
harmful emissions from propane engines include:
Carbon monoxide (CO), Nitrogen oxides (NOx)
and Hydrocarbons (HC). Propane, like butane or
methane, is odorless.An odorant (usually ethyl
mercaptan) is added to give propane its very
distinctive, pungent smell.The odorant acts as a
warningagentsothatleakscanbedetectedquickly.

Propane is unique because it is a gas at
atmosphericpressureandaliquidwhenstoredunder
pressure.Like any other liquid it expands when
heated, and it expands very rapidly.Compared
to water, propane will expand 17 times more in
volume with an identical increase in temperature.

Because of this expansion,propane fuel tanks are

are also equipped with pressure relief valves that

Propane gas is heavier than air, approximately
1.5 times the specic gravity of air.Therefore,
if propane leaks from the fuel system or cylinder
it will lay close to the oor and seek low places,

vaporizes and dissipates into the air.Because it
is released from apressured container as a vapor,
