How flammable is jet fuel?

Answer 1

Jet fuel comes in two basic types, Jet A and Jet B. Jet A-1 is the most common in use and there are other military spec fuels

Both are kerosene and paraffin oil based fuels. These are very similar to diesel fuel, stove oil or lamp oil.

Jet B is the more flammable of the two as it is made of hydrocarbons in the naptha/kerosene range for better cold weather service.

In either case the flammability is similar to or less than than gasoline, for Jet A it can be compared to diesel oil.

A third similar fuel is Avgas (Aviation Gasoline) which is a high octane gasoline similar to motor fuel.It is more flammable than gasoline or either of the jet fuels.

Answer 2

The Definition for Fuel is: Something consumed to produce energy, especially:

1. A material such as wood, coal, gas, or oil burned to produce heat or power.
2. Fissionable material used in a nuclear reactor.
3. Nutritive material metabolized by a living organism; food.

Therefore I believe the answer is Yes.

Answer 3

Jet fuel is highly flammable when exposed to a spark or open flame. Its flash point, the temperature at which it produces enough vapor to ignite, is relatively low compared to other fuels. Special precautions are taken in managing and storing jet fuel to prevent accidental ignition.
