Annual Forklift Inspections for LPG and CNG Certification

There are a number of ongoing certification requirements which LPG and CNG forklifts must adhere to, one of which is a comprehensive annual inspection. Australian Standards AS 4983-2010 stipulates the legislation for liquefied petroleum gas (LPG) powered forklifts and other industrial equipment, which includes a scheduled annual check to cover any deterioration that remains unnoticed.

All LPG systems require certification prior to being put into service, but an annual inspection must be passed for a successful renewal. If the forklift does not meet the required standard, the certification will no longer be valid.

Here is a summary of what is to be checked in an annual inspection of LPG and CNG forklifts for certification:


  • In accordance with clauses 7.6 and 7.8.3

Container identity (CNG)

  • Matching serial numbers on fuel container and refueling information plate
  • Containers not tampered with or modified in any way

Fuel container life

  • Check of date stamp or life expiry date in relation to the next annual inspection and pursuit of re-inspection and recertification (LPG) or removal and disposal (CNG) if required

Container recertification date (CNG)

  • Check of date stamp in relation to retest date and recertification date

Fuel container damage

  • Dents, fire damage, fatigue, bulging, cuts or gouges, sharp impressions or creases on the container body, protective fittings, mountings, compartments, sub-compartments, pipework, heat shields or guards

Fuel container corrosion

  • Especially in areas such as those susceptible to water accumulation, drip lines, clamping bands and release bands.

Container attachment

  • Corrosion, impact damage, abrasion, rust, cracks and metal fatigue
  • Tightness and condition of loose bands, wear under bands and fasteners
  • Correct orientation of fuel container
  • Adjustment of quick release container bands

Automatic fill limiter (LPG)

  • Accuracy of fill limiter

Safety fuel shut off system (LPG)

  • Proper function of automatic fuel shut-off devices or excess-flow valves

Fuel control systems

  • Proper function of fuel shut-off devices and fuel changeover systems

Manual valves

  • Function of valves
  • Leakage around connections

Compartment or sub-compartment

  • Structural damage, deterioration, kinking, punctures, leakage

Refuelling connection

  • Integrity of dust cap
  • Damage or contamination of connections
  • Housing properly attached
  • Deformity of remote fill line

Hydrostatic relief valve (LPG)

  • Damage, blockage or tampering

Protrusions from mobile equipment

  • Components, piping and containers that extend beyond the overall contour of the forklift

Equipment marking

  • Presence and legibility of all required plates and markings

Liquid filter(s)

  • Clean and intact

The forklift may fail the inspection if any parts are not present during the inspection if retrofitting is not possible. AS 4983-2010 includes specific guidelines on what form of damage and/or corrosion warrants the container being taken to a certified gas cylinder test station.
