Are LNG and CNG safe fuels?
Health & Safety issues have been the priority in the design and manufacture of the refuelling and vehicle systems. Natural gas is a far safer fuel than diesel or petrol for the following reasons: gas is stored in cylinders which are stronger than thin skin petrol/diesel tanks; several safety features prevent over-pressurisation; natural gas is non-toxic and lighter than air so will rise and disperse if a leak occurs. Natural gas is unlikely to ignite in a road accident situation, having a much higher ignition point than diesel.
