CNG has a narrow flammability range
It is far more likely that either gasoline or diesel would ignite than natural gas
Natural gas is non-toxic, non-corrosive and will not contaminate groundwater
Compared to gasoline, CNG reduces carbon monoxide emissions by 90- 97%, nitrogen oxide by up to 60% and hydrocarbon by 50-75% CNG storage cylinders are subjected to severe abuse tests that include heat and pressure extremes, gunfire, collisions, and fires before they can pass inspections
Natural gas is lighter than air and will dissipate rapidly rather than pool in one place
