Liquid Petroleum Gas (LPG) – General Information

LPG is liquefied petroleum gas and is:

 Obtained during the processing of crude oil, or direct from the North Sea.

 Colourless and odourless. An odourising agent is added before distribution to give its

characteristic smell.

 Half as heavy as water when in liquid form. It will float on water before vaporising.

 Easily liquefied by pressure, taking up only around 1/250th of its gaseous volume. This

means that a large amount of LPG can be stored in a small place.

 Either commercial butane or commercial propane. These are similar in use but propane

has a lower boiling point and hence a higher storage pressure. Commercial propane is

predominantly an outdoor fuel, commercial butane is predominantly an indoor fuel.

Hazards

 LPG is approximately twice as heavy as air when in gas form and will tend to sink to the

lowest possible level and may accumulate in cellars, pits, drains etc.

 LPG in liquid form can cause severe cold burns to the skin owing to its rapid vaporisation.

 Vaporisation can cool equipment so that it may be cold enough to cause cold burns.

 LPG forms a flammable mixture with air in concentrations of between 2% and 10%. Your

device is designed to warn you at 0.16% concentration BV (by volume of air) and will

alarm at 0.2% BV – this is 8% & 10% of the Lower Explosive Limit (LEL).

 Vapour/air mixtures arising from leakages may be ignited some distance from the point of

escape and the flame can travel back to the source of the leak.

 At very high concentrations when mixed with air, vapour is an anaesthetic and

subsequently an asphyxiant by diluting the available oxygen.

 A vessel that has contained LPG is nominally empty but may still contain LPG vapour and

be potentially dangerous. Therefore treat all LPG vessels as if they were full.
