LPG (Autogas) has been safely used in vehicles in Australia since the early 1970’s.
Some would argue the manner in which LPG is stored in a vehicle is safer than petrol.
LPG conversion systems have a number of important safety features including:
- A 3mm welded steel pressure vessel (tank) that is designed to withstand many times its maximum operating pressure. (Whereas many cars are now fitted with composite or plastic petrol tanks).
- Electronically controlled shut-off solenoids which stops the flow of gas to the engine if the engine stops for any reason.
- Pressure relief valves for the tank and the system – to prevent any pressure build up that may damage the system – or be hazardous.
- Double back-check valves to ensure gas tight filling
- Sealed compartments and venting around valves and pipe work – to ensure no LPG enters the interior of the vehicle
- Approved components to ensure long service life.
- The support of trained personnel who comply with rigorous Australian Standards for manufacture and installation of the system – in new cards at the production line – or vehicles retrofitted (converted) after purchase.
AS1425 LPG Fuel Systems for Vehicles is the Australian Standard that regulates the installation and maintenance of LPG systems in Australia. The specifications and requirements of AS1425 are some of the most stringent in the world, and mechanics need to undergo specific training in LPG installation and servicing before they can be certified to work on LPG vehicles.
LPG has an odourant added to it so that if there is a leak at theservice station or in your fuel line, it can be easily detected by anyone. As LPG is heavier than air, the LPG installation is fitted so that even in the unlikely event of a leak, the LPG is vented safely outside the vehicle.
All of the above safety factors are reflected in the fact that no additional premiums are charged by insurance companies for running your vehicle on LPG, as underwriters consider no additional risk in using LPG compared to conventional fuel.
