Is there is a requirement for company vehicles to have a fire extinguisher?
There is no blanket requirement for all company vehicles to have a fire extinguisher. A risk assessment of the company vehicle will need to be undertaken to determine whether there are any fire risks and the extent of those risks, e.g. if the vehicle carries hazardous substances. If so, having fire extinguishers in the vehicles may be one reasonably practicable way of managing those risks.
