The Safety Of Compressed Natural Gas

"Stephe Yborra from NGV America navigates through the safety and realities of driving a natural gas vehicle."

• Natural gas is lighter than air, so if there is a leak it floats up and away, rather than pooling around the leak as gasoline would.
• CNG tanks are built stronger than standard gasoline tanks. Even if hit by rifle fire, they do not explode (but they will leak).
• In a fire, safety valves will relieve pressure in the tank long before burst pressure is reached. The result may look like "a large Bunsen burner."
• Explosions require fuel and oxygen, Mr. Yborra says. There is no air in the tank.
• Performance of natural gas vehicles equals or exceeds that of gasoline-powered vehicles.
