What are the safety issues with gaseous fuels?
First of all the safety regulations for all fuels – whether liquid or gaseous – will generally ensure that the risk of a fire under normal operating conditions is very small indeed. So it is generally in the event of a crash or equipment failur that a hazard will occur. As with most fuels the main fire hazard comes from leakage – either during refuelling operations or during operation of the equipment, a vehicle crash etc. In any of these situations there needs to be all of three requirements before there is the potential for a fire or an explosion. First the leakage of the fuel, second a situation where a mixing of the fuel with air gives a mixture in the flammable range and third a source of ignition. Most gases have an oderant added so that leakage can be detected by people in the vicinity. Once a leakage occurs and a source of ignition is present – say a spark or a naked flame of sufficient energy – there must still be a mixture of the gas in the flammable range. The likelyhood of

As with most fuels, the main fire hazard comes from leakage – either during refuelling operations or during operations of the equipment, a vehicle crash etc. In any of these situations three requirements are needed before there is the potential for a fire or an explosion. First, there must be leakage of fuel, second, mixing of fuel with air to create a mixture in the flammable range and third, a source of ignition. Most gases have an odorant added so that leakage can be detected by people in the vicinity. Safety systems have been incorporated into the fuel storage system to provide safe operation of the vehicle. The hydrogen detection system consists of four hydrogen sensors: two in the trunk, one under the hood and another in the passenger compartment. Hydrogen is safer than gasoline. It is lighter than air an
