Breif introduction:
What is the difference between Natural gas and LPG ?
Natural Gas is lighter than air so it tends to dissipate into the atmosphere. However when it is used in a confined space , such as a building, caravan, office, kitchen, loungeroom etc.. the gas concentration can increase beyond its lower explosive limit (between 5 and 15% in air) . In the presence of any ignition source this can create an explosion.
Natural Gas is a fuel consisting mostly of methane. When it is required as a fuel it must be purified to remove a number of other constituents, namely ethane, propane, butane and sulphur among others.
Natural gas can be very hazardous with its potential to ignite and cause explosions.
Although not strickly poisonous to the human body it can become lethal when concentrations build up to such a level that it displaces air (oxygen) causing asphyxiation.
LPG (Liquified Petroleum Gas) is a mixture of a number of hydrocarbons primarily consisting of mixes of propane and butane. LPG has a very low boiling point so in order to prevent evaporation the gas is stored under very high pressure where it becomes a liquid.
LPG is heavier than air so it will naturally tend to flow to the floor. This characteristic is why leaking LPG is so dangerous, particularly in the home , caravan or cabin.
As most people sleep in relatively small confined spaces (and low to the floor) the consequences of an LPG leak can be tragic.
