Consists mainly of methane. The large proportion of methane is one of the reasons natural gas has such a good safety record.
Methane is lighter than air and will disperse relatively easily if there is a gas leak.
Liquefied Petroleum Gas (LPG)
Is a hydrocarbon fuel comprised primarily of propane or butane, either separately or as a mixture.
LPG is non-toxic, and non-corrosive.
LPG is produced during the production of oil and gas, and is stored in tanks and transported by road tanker trucks or in cylinders.
LPG is mainly stored in tanks in liquid form and is heavier than air.
LPG tends to collect in low points and is more difficult to disperse than natural gas, so is therefore more prone to catch fire or explode if a leak occurs.
