COMPRESSED NATURAL GAS (CNG) SYSTEMS
Natural gas dissipates rather than pooling around a leak.
Natural gas is lighter than air and therefore dissipates upwards and away from the an accident site should a leak occur. Liquid fuels and LPG are heavier than air and flow or sink downwards pooling around the vehicle and creating a highly hazardous environment where there are potential ignition sources. Should these fuels ignite a conflagration will result and will continue to burn in the immediate vicinity of the accident.back
