What is a danger associated with natural gas in the back of a vehicle?

A Boiling Liquid Expanding Vapor Explosion (BLEVE) occurs when a container of liquefied gas, such as natural gas, is subjected to intense heat or pressure, causing it to rupture and release flammable vapor. In the context of natural gas in the back of a vehicle, if a source of ignition is present, the release of gas can lead to a BLEVE. The danger arises from the potential for the gas to ignite upon release and create an explosive situation. BLEVE events are particularly hazardous because they can result in a significant explosion and fireball, posing an extreme risk to life and property nearby.

The other options represent different hazards associated with firefighting and fire behavior. Flashover refers to a rapid spread of fire due to the ignition of combustible materials in an environment, which could occur in other scenarios but is not specifically tied to natural gas in the back of a vehicle. Backdraft is related to the sudden ignition of unburned gases in a confined space when oxygen is introduced, which doesn’t apply directly to the scenario described. Lastly, while a ground fire can occur, it does not capture the specific explosive nature of natural gas being stored in a vehicle the same way a BLEVE does. Thus, the significant explosive risk
