Storing and transporting LPG
Gas bottles always need to be kept in an upright position on a solid base – otherwise they can't vent properly. And they can't be stored indoors, in direct sunlight or near an ignition source.
Only smaller gas bottles that weigh 13.5kg or less are safe to transport in your car. They need to be kept upright in your boot or tray, with the valves turned off. In Queensland, gas bottles that weigh 9kg or less must also be fitted with a screw-in plastic plug.
