FL (Siamesed) = C x (Q/a hundred)² x (L/one hundred)
FL (Siamesed) =.2 x 350/100/2 x one hundred FL (Siamesed) = .2 x (three.5)² x 3
FL (Siamesed) = .2 x 12.25 x three
FL (Siamesed) = 7.35
FL (Attack 1) = C x (Q/one hundred)² x (L/one hundred)
FL (Attack 1) = .08 x (350/100)² x (2 hundred/100)
FL (Attack 1) = .08 x (three.5)² x 2
FL (Attack 1) = .08 x 12.25 x 2
FL (Attack 1) = 1.96
TPL = FL + EL + APL
TPL = (7.35 + 1.96) + zero + (10 [appliance] + 25 [master stream])
TPL = 9.31 + 0 + 10
TPL = 44.31
A quantity of 16.66 pounds of water equals: - ANS-A. 16.Sixty six gal
B. 8.33 gal
C. 6.Seventy eight gal
D. 2.0 gal (Correct Answer)
, 1 gal = 8.35 lbs
sixteen.66/eight.35 = 1.Ninety nine

All of the subsequent are rescue gear EXCEPT: - ANS-A. Spreaders
B. Rams extensions C. Drills (Correct Answer)
D. Shears
All of the following statements about driving a fireplace apparatus through areas of constrained
horizontal and vertical clearances are actual EXCEPT: - ANS-A. Use your facet view mirrors
B. Make certain you can see your spotter
C. Judge your fire apparatus' clearance around obstructions (Not Correct)
D. Use the right turn sign
All of the following statements approximately static sources are proper EXCEPT: - ANS-A.
Pre-incident planning must be executed to assess the accessibility of static waters assets
B. Weather can dramatically have an effect on the accessibility and value of static water
sources
C. The static water assets that is closest to the incident need to be usually used first (Correct
Answer)
D. Safety of the gadget and group is paramount while deciding on a static water supply
Allowing the hearth equipment engine to idle over an prolonged time period can result in all the
following EXCEPT: - ANS-A. Fuel Waste
B. Engine fatigue (Correct Answer)
C. Engine wear
D. Engine debris accumulation An essential consideration while figuring out the placement of a
fireplace apparatus is the: - ANS-A. Manpower available
B. Distance from staging
C. Method of assault (Correct Answer)
D. Location of automobile parking space
As salt water or water containing certain chemical compounds can corrode the apparatus
pump, you ought to: - ANS-A. Never use static sources of water that are not potable
B. Before you connect the strainer, install a opposite osmosis (RO) filter at the consumption
hose to lessen the consequences of chemical substances and salt. C. Flush the pump with
sparkling water after the usage of it (Correct Answer)
D. Flush the pump with a neutralizer and clean water after using it.
, Before driving over a guarded railroad crossing during an emergency reaction: - ANS-A. Look
both proper and left and proceed cautiously (Correct Answer)
B. Look to the proper, the gate could be up on the left
C. Look to the left, the gate will up on the proper
D. Bring the equipment to a whole forestall
Bouncing water off the interior partitions of the nozzle bore to create a fog pattern is referred to
as: - ANS-A. Periphery deflection (Correct Answer)
B. A shattered movement C. An impinging movement

Calculate the capacity of this pool. The average intensity is five feet
Pool is 40 feet via a hundred and fifty Feet - ANS-A. 6,000 gallons
B. 30,000 gallons
C. One hundred twenty five,000 gallons
D. 225,000 gallons (Correct Answer)
7.5 (L) (W) (D) gallons of ability Capacity in gallons = 7.5 (a hundred and fifty) (forty) (5)
Capacity in gallons = 225,000
Calculate the gpm flowing from a 1 three/four inch strong grasp stream nozzle running at a
nozzle stress of eighty psi. - ANS-A. 801 GPM
B. 464 GPM
C. 813 GPM (Correct Answer)
D. 406 GPM
Q(Total) = 29.7 x (d)² x (√NP)
Q(Total) = 29.7 x (1.Seventy five)² x (√80)
Q(Total) = 29.7 x 3.0625 x eight.9442
Q(Total) = 813.Fifty three

Determine the approximate TPL for a hose assembly wherein there's 500 ft of a 4-inch supply
line wyed into , 2 ½-inch assault traces which are 200 toes lengthy. Each assault line is flowing
250 GPM. - ANS-A. 50 psi
B. 60 psi (Correct Answer)
C. Ninety six psi
D. 106 psi
FL (Supply Line) = C x (Q (Supply)/100)² x L/100
FL (Supply Line) = 0.2 x (500/one hundred)² x 500/100
FL (Supply Line) = 0.2 x (five)² x five
FL (Supply Line) = zero.2 x 25 x five
FL (Supply Line) = 25
FL = 2 x (250/one hundred)² x (two hundred/a hundred)
FL = 2 x (2.5)² x 2
FL = 2 x 6.25 x 2
