HSE notice regarding fire risk on forklift trucks using l. p. gas

L P Gas bottle on forklift truckIssue

HSE is aware of a number of fires on, and around, liquefied petroleum gas (LPG) powered forklift trucks and other similar vehicles that have occurred during starting.

Outline of the problem

Build-up of deposits in fuel systems, in particular, the vaporiser units of LPG powered vehicles has led to a number of fires.

Trucks not starting due to sticking valves

Deposits in vaporiser units, flow regulators and shut off valves cause the truck to fail to start, particularly from cold. Build-up of deposits can lead to sticking valves and the mixture supplied to the engine being too rich to be ignited.

Repeated starting attempts can release unburned LPG

Repeated starting attempts can result in the release of unburned LPG, which in extreme cases can be ignited, setting fire to the vehicle and surrounding materials.

Action required by operators

If a truck does not start within the normal few seconds

Service and maintenance engineers

If you are presented with an LPG powered truck with a starting problem:

LPG is cold, take appropriate precautions when working with it. Once released LP gas is heavier than air and can pool in low lying areas, where it can be ignited by any source of ignition, including static electricity, electrical sparks and hot surfaces.
