What is the primary hazard associated with jet fuel?

The primary hazard associated with jet fuel lies in its high flammability and the potential for explosive vapor formation. Jet fuel, being a type of kerosene, has a low flash point, which means it can easily ignite when it comes into contact with an open flame or a spark. This characteristic leads to the creation of flammable vapors that can accumulate, especially in poorly ventilated areas, resulting in a significant explosion risk if ignited.

It is critical for airport firefighters to recognize this hazard because during an incident involving aviation fuel, rapid response and effective firefighting measures are necessary to mitigate the risk of fire and explosion. Understanding the behavior of these vapors can aid in safe handling, storage, and response procedures in the event of a fire involving jet fuel. The other aspects noted, such as viscosity, weight, and freezing point, while relevant in certain contexts, do not pose as serious a risk when compared to the flammability and volatility of the fuel.
