A _______ is the burning of a stream of gas, vapor, or liquid.

A _______ is the burning of a stream of gas, vapor, or liquid.

• A. Flash fire
• B. Jet fire
• C. Backdraft
• D. Combustion

Answer: (B)

Jet fire refers to the burning of a stream of fuel as it jets from a release. When gas, vapor, or liquid is released under pressure, it can form a narrow, directed stream that continues to burn along its path, producing a flame attached to and traveling with the jet. This is different from a flash fire, which involves rapid ignition of a broader vapor cloud near surfaces; from a backdraft, which is ignition of accumulated gases in a confined space when air re-enters; and from combustion in general, which is simply the chemical reaction of a fuel with an oxidizer. The term jet fire is the precise description of a flame sustained by a moving stream of fuel.
