Semi-annually or when necessary
Pump idle pressure always equals the pressure the pumps provide at its lowest RPM (around _ in vol & _ in pressure)
55 psi in volume & 110 psi in pressure plus the intake pressure received from water source (hydrant approx 50 psi + 55 vol= 105 psi)
P-3 1.7
ECC gives correct flow of 180 GPM- suddenly Officer is calling for more water & flowmeter dropped to 110 GPM; Now lost pressure & flowmeter increased to 230 GPM
Drop= Kinks;
Increase= Burst length

1st to arrive on 1st alarm use _ to hook up to a hydrant
Other than 1st to arrive on 1st alarm
2nd/greater alarms
2-3-1: 10' small hydrant connection or 35' soft connection 10' small, 35' soft, or 10' hard suction 10' hard suction must be used P-3 4
Drafting use
When ILP _ shall be initial supply line
10’ hard suction must be used
3 1/2” HL - also if hydrants are unlawfully blocked
P-3 4
Connect to the (hydrant/rig) first
If using a gated inlet, what must be done 1st
Hydrant- in case repositioning is needed
Open the drain to gated inlet to expel air prior to opening gated inlet
P-3 5.1
When residual pressure drops below _ on intake pressure gauge augmentation will be required
Below 15 psi
P-3 6.4
T/F After water is introduced into the pump, before increasing pump pressure, & opening any discharge outlets, primer must be utilized
True- must prime before opening initial line at any HL
P-3 8.1
T/F You must bring hydrant water into the pump through a gated inlet when operating booster water
True: removing the cap of NON-gated inlet will cause loss of water from booster tank & introduce air losing prime
P-3 10.3.4
What bulbs do FF’s replace
Headlight bulbs- all other bulbs notify Fleet Services
When tread wear on tires reach _ request replacement
3/16” in depth
Friction loss for 1 3/4” HL vs 2 1/2” HL
1 3/4” with 15/16” MST loses 50 psi at noz + 20 psi per length
2 1/2” with 1 1/8” MST loses 40 psi at noz + 5 psi per length
Both lose 5 psi for each story above ground
P-3 12.2
PPG shall be used in _
Pressure Mode & NOT RPM mode (unless emergency and HL should NOT advance & should be backed out to an area of refuge)
P-3 1.8
Incorrect for flowmeters
A. Designed to measure rate of flow of water in a confined space as it passes a given point at a given time
B. Registers readings whether water is flowing or not flowing
C. Displays are represented in gallons per minute
D. Used by ECCs to determine problems w/an operating HL
B Water Flowing
P-3 1.12
Which accurately describes the Pro-Pressure Governor on Dept Eng rigs
A. Controls discharge pressure of the pump
B. Enables the pump to operate in either Pressure position or Volume position
C. Positive displacement pump
D. Indicates negative or vacuum pressure
A
P-3 1.8
B. PPG can operate in Pressure Mode or RPM Mode
C. Priming Pump is a positive displacement pump used to evacuate air from the pump chamber
D. Pressure gauges indicate Positive, Negative, or Compound gauges
FDNY standard operating procedures require the PPG to operated in what mode A. Idle B. Pressure C. Volume D. RPM
B Note: FDNY standard operating procedures requires the PPG be operated in the pressure mode. This is the default mode. This should NOT be confused with the Pumps Pressure Position.
P-3 1.8
The 100' AL operates by utilizing two double acting hydraulic lift cylinders. What is the load capacity range of this ladder A. 200-1050 lbs B. 250-750 lbs C. 300-1250 lbs D. 350-1300 lbs
B
What is the distance needed on each side of the rig for clearance when utilizing the 100' AL "H" frame stabilizers A. 5' 2" B. 6' 10" C. 7' 4" D. 8' 6"
A
Why is it important to match up the Extension Footage & Inclinometer numbers on the 100’ AL when it’s in use
A. Determine rung alignment
B. Determine if the AL sections are locked
C. Determine proper load capacity
D. Determine if AL if fully extended
C
AL short jacked... Unless the override is hit... How far of an angle can the ladder swing towards the short jacked side? A 10 degrees B 15 degrees C 20 degrees D 30 degrees
B 5.4.1 App 7
Correct for AL parked on a narrow street
A. Inboard stabilizer on working side must always be extended & lowered 1st, even when the ground isn’t level
B. If the ground is not level, always ensure the high side stabilizer is fully extended horizontally & lowered to its maximum
C. LCCs may have to forego a better position for the use of the AL to a less desirable location in order to allow full horizontal extension of the inboard stabilizer
D. Where stabilizers are not fully extended horizontally, AL rotation of more than 30 degrees from center line of rig towards a short-jacked stabilizer will be prevented by the Rotation Limiting Device
C
L-7 3.3, 5.4.1, 5.4.4
A & B. Begin extending & lowering inboard stabilizer (working side) 1st. When ground is NOT LEVEL low side stabilizer shall be fully extended horizontally & lowered to it max. High side shall then be extended as necessary & lowered to a point that levels the rig. If inboard stabilizer (working side) is also high side, it must be fully extended horizontally & then lowered to level rig. This may require LCC forego a better position for use of AL to a less desirable location such as deploying stabilizer between 2 parked cars
D 15 degrees from center line
