CNG is CleanCNG is Clean

• Unlike gasoline vapors, CNG is lighter than air and dissipates rapidly.

• CNG has a narrow flammability range (more difficult to ignite).• CNG uses stronger components and storage systems.• CNG vehicles meet all of the same safety standards and crash

test requirements of gasoline vehicles.
