with 70 Questions and 100% Verified Detailed
Correct Answers Guaranteed
_____________ is the result of incomplete combustion - CORRECT ANSWER: smoke
Black or dark grey indicates a ______ fire or a _________ of oxygen - CORRECT
ANSWER: hot, lack
Chain reaction - CORRECT ANSWER: -you can have oxygen, heat, and fuel in the
same place and still not have a fire
-fuel and oxygen relationship must be balanced (i.e. in the flammable range)
-heat must be sufficient to bring fuel to its ignition
Fog Applicators - CORRECT ANSWER: -both high and low velocity extinguish fire by
absorbing heat
-can possibly help by reducing, but not eliminating the supply of oxygen
-are used with the all purpose nozzle
- there are three types: 60 deg 4 ft, 90 deg 10 ft, 90 deg 12 ft
Fuel - CORRECT ANSWER: -only vapors burn
-liquids and solids must first be vaporized
-tendency of a substance to vaporize is an indication of its ability to burn
-liquids vaporize more readily than solids
Heat - CORRECT ANSWER: anything that produces the required temperature for
ignition
-sun
, -open flame
-chemical reaction
-sparks
-friction
How are gases produced? - CORRECT ANSWER: result of combustion, may or may
not be toxic
How do you stop a fire? - CORRECT ANSWER: Remove any of the components of the
fire tetrahedron (i.e. remove fuel, oxygen, heat, or interrupt the chemical reaction)
How does the spread of fire occur? - CORRECT ANSWER: result of equalization in
temperature between fire and surrounding areas via conduction, radiation, and
convection
How is flame produced? - CORRECT ANSWER: result of conversation of the fuel to a
state of blazing combustion
How is heat generated? - CORRECT ANSWER: rapid oxidation of the material
In Fire Fighting what 4 aspects do you need to keep in mind? - CORRECT ANSWER: -
time is critical (fight the fire in the incipient stage)
-awareness (know location/type of fire fighting equipment and know how to use it)
-pick the right tool for the job
-stay low (cooler air, better visibility)
Navy All-Purpose Nozzle - CORRECT ANSWER: -solid steam, high velocity fog, low
velocity fog when used with applicator
Oxygen - CORRECT ANSWER: -21% ambient air
-robust flaming combustion down to 15-16%
