The Health and Safety Executive (HSE) recently issued an update regarding LPG forklift truck fire risks. They highlighted concerns about numerous reported fires on and around LPG-powered forklift trucks during starting, often linked to the build-up of deposits in fuel systems, particularly in vaporiser units.
The update emphasised mechanical issues such as deposits causing starting failures, affecting flow regulators and shut off valves, and leading to sticking valves that create a rich mixture unable to ignite. Starting failures, especially in cold conditions, were a significant point of focus, with trucks not starting due to sticking valves caused by deposit build-up.
The HSE highlighted the danger of unburned LPG posing a fire hazard. When starting attempts fail, unburned LPG can be released, potentially gathering in low areas and igniting from various sources due to its tendency to sink.
