T or F.
During application of foam onto a burning surface of fuel, the fire can burn back across the surface as soon as the particular extinguishing agent begins to break down if the fire is not completely extinguished.
T or F.
Fluoroprotein foam shall be generated with fresh water only. Salt water will disrupt the extinguishing agents in the foam.
Fluoroprotein foam can be generated with either fresh or salt water.
If a foam eductor cannot be placed into operation, the premixing of fluoroprotein foam solution can be accomplished by dumping ___ 5-gallon cans of concentrate into a 500-gallon booster tank to produce a ___% solution.
3 5-gallon cans into 500-gallon tank producing a 3% solution. (If a 750-gallon tank, use 4 5-gallon cans.)
Foam section 4.2
A first alarm assignment provides ___ gallons of foam. With one handline in operation approximately ___ sq ft of fire can be extinguished.
A) 55 and 500
B) 75 and 700
C) 65 and 600
D) 45 and 400
C. Engines carry 3 5-gallon cans. Trucks carry 2 5-gallon cans. With a 3 and 2 response, thats a total of 65 gallons covering approx. 600 sq ft.
Foam sec. 7.3.1
A sharp lieutenant drilling with his men knows that during a bulk oil tank incident, it is more dangerous for a tank to be partially full than a full tank of fuel.
True or False.
True. A partially full tank is full of vapors. It is much more dangerous than a full tank which acts as a heat sink.
Foam section. 7.6.7

A) 5 & 10
B) 10 & 15
C) 10 & 20
D) 5 & 15
E) the above statement is incorrect. Foam does not have a shelf life.
C) 10 years for protein based & 20 years for synthetic.
Foam sec. 9.2

A) 100 psi
B) 150 psi
C) 200 psi
D) 250 psi
C. 200 psi at the eductor
