Exam 6 Flashcards
Question 1:
BC Keiger is assigned to oversee an engine company at the third alarm 10-76. This engine is tasked with operating the building’s fire pump. Which choice below contains correct information regarding fire pumps and the bypass valve?
A: The bypass valve should be in the open position (stem out).
B: If found to be open, the valve should be closed by turning in a clockwise direction.
C: Some systems are quite complex and the bypass valve is not readily discernible. If such a situation is present, it is never permissible to start the pump as ordered until finding and operating the bypass valve.
D: The efficiency of the pump will be affected if the bypass is open. A loss of 45% can be expected in a 8” riser and a loss of 25% can be expected in a 6” riser with the bypass open.
B
Explanation:
A) The bypass valve should be in the closed position (stem in).
C) Some systems are quite complex and the bypass valve is not readily discernible. If such a situation is present, it is permissible to start pump as ordered without checking bypass valve.
D) The efficiency of the pump will be affected if the bypass is open. A loss of 25% can be expected in an 8” riser and a loss of 45% can be expected in a 6” riser with the bypass open.

Question 3: You are special called as the foam coordinator to a fire in a crawl space of a commercial building 100x100 that is 5' high. If the generators we use to deliver hi-ex foam are 7500 CFM, then how many would you require to deliver enough foam to extinguish an advanced fire in the crawl space? A: 2 B: 3 C: 5 D: 7
A
Explanation:
FOAM 13.18 pg 27
I hate math questions, but all of the information is in the bulletin…
LxWxH divided by 5 minutes is the formula
The correct answer is A – 100x100x5 = 50000 cubic feet. You have to divide that number by 5 minutes to get 10000 cubic feet. That would require 2 generators. If you forget to divide by 5, you get choice D. You won’t have the formula in front of you on game day…
