Is compressed natural gas safe?
A. Yes. The cylinders that hold the compressed natural gas are significantly stronger than gasoline tanks. They have withstood impact and bonfire testing and meet or exceed U. S. Department of Transportation safety standards. Even in the unlikely event of a leak, CNG will not form combustible pools on the ground, as other fuels do. Because it is lighter than air, it will rise and dissipate if released. Furthermore, natural gas is not toxic to touch.
