TB C2, L7, P2 & 3 Flashcards
Beginning each tour immediately after 0900 & 1800 Roll Call: check “Tourly, Tourly FLAWS” on rig
Tiller buzzer (SB 10), Tiller wheels aligned (SB 10), Fill fuel tank, Lights (non-response: we can only change headlights), Air tanks purged (particularly important in sub-freezing weather), Warning devices (need 1 audible device & lights to remain I/S), & Seat belts
Air loss over these amounts notify Fleet Services
Max 1 lb per 10 min or Max 10 lbs per application
Inspection of Wheel Checks shall be performed
TL intercom tested
Daily- make sure all are in sequence
Daily
Weekly maintenance of rig “Always Have The Probie Test Each Exam Weekly” or “8 Days a Week” 8 things weekly
Air cleaner (green), Hydraulic system of AL/TL, Transmission fluid, Power steering, Tire maintenance, Electric fuel pump primer for 5 sec, Emergency system of AL/TL for max of 30 sec, & Wheel lugs
Snow chains can approximately _ your vehicle’s starting & stopping traction on snow & ice
Chains on wheels- do not exceed _ mph
Double (only full chains used NO strap style)
30 MPH
The 100’ AL provides precise elevation from _ to _ degrees above horizontal
Which stabilizer should be lowered 1st on AL
0-80 degrees
Inboard- working side
A stabilizer on AL that is NOT fully extended horizontally is considered _
When the ground is not level & the rig is leaning start w/stabilizer on _
Short-jacked
lowest side 1st (direction rig is leaning)
Units shall calibrate their flowmeters _
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
P-3 1.12
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
