Gas Safety

Liquefied Petroleum gas (LPG) is convenient, clean, relatively inexpensive and for most caravanners or campers readily available. However, it is also flammable. Below are some hints which will help keep your system operating safely and efficiently.

LPG consists basically of propane which is a by-product of petroleum processing. Existing in a vapour for at atmospheric pressure it changes to a liquid when stored under pressure. Inside a cylinder the pressure varies from 350 kPa (50 psi) at OpC to 1400 kPa (200psi) at 45pC. This means that it is possible for a larger quantity gas to escape rather quickly if handed carelessly.

Because LPG is heavier than air it will always find the lowest place or stay close to the ground floor. Ventilation therefore is very important, particularly in confined spaces like caravans. The practice of blocking off air vents to keep put draughts is a dangerous one and is not recommended. As most gas facilities and installations are covered by regulations, a little care by the user can prevent accidents.

The gas systems should be inspected regularly and any service work carried out by a licensed gas fitter. A 'certificate of compliance' has to be issued on the completion of any work carried out on a LPG system.


These must be stored upright and securely fastened. All cylinders normally used on caravans and camper trailers are fitted with a safety relieve valve. This is designed to release gas to the atmosphere should a high pressure build up occur in the cylinder usually as the result of very high temperatures. Always make sure that this is relief valve is pointing away from both the caravan and towing guide.

For cylinders not stored under cover a coat of paint once a year will prevent rust formation. Every ten years, from date of manufacture, all cylinders mist be inspected and retested.
