Getting LPG on your vehicle
Are you interested in getting LPG for your vehicle? There are a few things that you need to know to ensure the work is done legally and safely.
Firstly, any installation or repair work in Queensland on gas fuelled engine must be undertaken by a company or person holding a gas work authorisation (motor fuel). A list of current holders (PDF, 28 kB) of these authorisations (those authorised to install LPG in vehicles) will be updated monthly.
Secondly, on completion of the installation, the installer must give you a vehicle/vessel inspection certificate (Approved Form PGR101/102). This certificate certifies that the installation compiles with the relevant legislation and meets all the safety requirements. It is very important that you get this certificate and retain it for your records.
Selling your LPG vehicle
If you sell your vehicle that has a gas fuelled engine you will need to have the gas fuel system inspected and a vehicle/vessel inspection certificate issued. This can be obtained from an authorised automotive LPG gas installer (PDF, 28 kB). You must give a copy of the inspection certificate (valid for 3 months from the date of issue) to the buyer of the vehicle. Owners of commercial vehicles must get their vehicle inspected and certified every 12 months.
Applying for an exemption from obtaining a vehicle/vessel inspection certificate
The process (PDF, 24 kB) for applying for an exemption from the requirement to obtain a vehicle/vessel gas inspection certificate should be followed.
LPG Vehicle Rebate
If you require information on the Australian Government's LPG Vehicle Scheme, contact the AusIndustry hotline on 13 28 46. You can obtain the application form and other LPG Vehicle Scheme customer documents by visiting the LPG Vehicle Scheme website.
If you want to know more about LPG in general visit LPG Australia or RACQ.
Sidek Safety Relief Valves
Some Sidek brand PRX safety relief valves supplied between September 2001 and August 2005 do not operate correctly and could result in a dangerous situation.
Check your safety relief valve -The valve is located at the side of the tank and may be in a sub-compartment.

If you have one of these Sidek valves or if you cannot identify the valve, have an automotive LPG installer (PDF, 25 kB) or gas cylinder test station (PDF, 12 kB) check and replace any Sidek valve as soon as possible.
Some frequently asked questions (PDF, 18 kB) have been developed to answer likely questions you may have. LPG Australia (scroll to Safety Alerts) also has some detailed information on this issue.
If you have additional queries email GasSafe Department of Natural Resources and Mines or phone (07) 3237 1626.
Information for Queensland gas motor fuel installers
Anyone who installs, removes, alters, repairs, services, tests or certifies a gas fuel engine in vehicles, forklifts, vessels (marine) or stationary engine (up to 5 GJ/hour capacity) must have or be working under a gas work authorisation (motor fuel) issued under the Petroleum and Gas (Production and Safety) Act 2004.
Authorisations are designed to allow businesses/organisations to undertake gas work on Type B gas devices. If you work for a company, the company must apply for the authorisation. In this case, the application should be made by the Chief Executive or a senior person in the organisation who will be responsible for the work being undertaken.
Sole traders can also apply for a gas work authorisation.
Workshops
LPG gas fuelled engine installations/conversions must be undertaken in a workshop that complies with the workshop area and equipment requirements of AS2746:1999 'Working areas for gas fuelled vehicles'.
A workshop checklist (PDF, 31 kB) has been developed to enable applicants and holders of a gas work authorisation (motor fuel) to understand the requirements of obtaining an authorisation and the Petroleum and Gas (Production and Safety) Act 2004, and AS2746:1999 'Working areas for gas fuelled vehicles' with regard to workshop areas and equipment. This checklist is also included in the application form for an authorisation. Please note that before a gas work authorisation (motor fuel) is granted the workshops will be inspected by a Petroleum and Gas Inspector to ensure they meet the requirements.
Applying for an Authorisation
If you want to apply for a Gas Work Authorisation (Motor Fuel) you will need to fill out a Gas Work Authorisation (Motor Fuel) Application Form (PDF, 116 kB).
Guidelines for Motor Fuel authorisations (PDF, 170 kB) are available to assist applicants to understand the requirements for making and working under an authorisation. People working under an authorisation must be trained and competent to undertake the tasks they are doing. Typically these are motor mechanics with specialist LPG or CNG competencies as detailed in the guidelines. Records of this training must be provided with the application. Formal training is available from certain TAFE colleges and private providers such as Automotive Gas Training Pty Ltd.
When an installation, repair or inspection is made a vehicle/vessel inspection certificate (Approved Form PGR101/102) must be issued. Authorised installers can purchase these forms from the Petroleum and Gas Inspectorate regional offices (see more information below).
