When using heaters which involve combustion of a fuel such as gas oil or L.P.G. adequate fresh air must be provided both to ensure the correct functioning of the equipment and to eliminate the risk of oxygen starvation and asphyxiation to anyone in close proximity to the heater.
L.P.G. (Liquid Petroleum Gas) is a colourless gas treated with a stenching agent to give it its characteristic smell. It is in liquid form under pressure in the bottle and vapourises as the pressure is released. L.P.G. is twice as heavy as air and any leakage will tend to collect in pits, cellars and drains. Low level ventilation is essential when using L.P.G.
Typical L.P.G. Bottle Classification
When buying gas either an empty gas bottle of the same size must be exchanged or a Gas Bottle Deposit paid.
