CNG cars are very intriguing to many people as they usually will run on regular gasoline and CNG. A common questions that is asked is, “how safe is a CNG car?” We want to answer that question in this article.
CNG tanks are made from an aluminum composite material which is extremely strong and durable. There is a video on our website which shows testers blowing up dynamite on it, shooting it with guns, and even cooking it in a fire without the integrity of the tank being compromised.
Safety valves are also included in all the CNG tanks which allow the tank to release the CNG into the air if there has been a collision to ensure maximum safety. These safety valves simply stay at the top of the tank and usually have a release tube so the gas is released outside of the vehicle instead of in the vehicle cab.
Many worry about natural gas igniting during a car fire, but this is a myth. Natural gas requires a lot more heat than regular gas to ignite. CNG has an octane rating that requires at least 1100 degrees of temperature to even ignite the gas.
Filling a natural gas tank is not scary and is extremely safe. Compression is around 4000 lbs per square inch when filling, but the tanks are rated to hold much more than that, so the worry of explosion is absurd. If a small spark happened or a cigarette was lighted it would not compromise the ignition of natural gas as alot more heat is required to light natural gas.
we hope that you can determine from this information the true safety of a CNG vehicle. These cars are great for the environment and are much cheaper to drive. If you are looking into buying a car like this rest assured that your safety is in good hands.
