Q

Grades up to _____________ slope may be treated as ground level regarding TL operations.

A

4% slope

17
Q

If possible, TL operations on a hill should be facing?

A

downhill – if facing downhill, turntable past objective, if facing uphill, turntable before objective

18
Q

Maximum “slope” for TL operation has been set at what by the manufacturer for safe performance?

A

15% grade

19
Q

What angle should be TL boom be raised to drain waterway?

A

60 degrees and drains of waterways and gated inlets opened

20
Q

What tools must be placed in the TL bucket when being used for ventilation purposes?

A

axe, halligan, power saw, 6’ hook, life saving rope — study aide: “H.A.S. 6 Lifes”

21
Q

When operating on a roof of questionable stability with hand tools/saw full use of personal harness and LSR shall be used to limit travel to a radius of no more than _______from basket.

A

10’ (rope shall be tied to substantial part of basket [other than railing] and operator shall use bowline with 15’ loop)

22
Q

Where is first cut of peaked roof when using saw from TL basket?

A

parallel to ridge pole (7 then 11) knockout cut is 4th cut

23
Q

To expedite placing of TL bucket at window, place apparatus ________ to the objective so that the __________ is in line with the window/target

A

parallel/basket

24
Q

To facilitate the removal of incapacitated or obese victims from a TL bucket, position the basket how?

A

position the top basket rail level with the windowsill or top rail of fire escape

25
Q

For rescue, where is initial placement of the tower ladder bucket placed in relation to the window or fire escape?

A

basket is elevated to a point where the MIDDLE railing of basket is level with the window ledge, or level with the top railing of the fire escape (this allows a person to easily step onto the basket floor)

26
Q

To insure smooth operation of a TL basket maneuver, who should perform the lowering of a vicitim in a bucket if conditions permit?

A

Pedestal man (diagonal placement of victim in bucket easier and safer)

27
Q

When fire building is heavily involved on several floors, a heavy stream delivery should generally start where and why is this?

A

at the lowest level and work upward, effecting a quick knock-down on the way up to the top floor/cockloft area in order to protect members in basket operating at the highest level

28
Q

What shall be attached to the nozzle on the stang of the TL bucket when a straight stream is ordered?

A

the stream shaper with a minimum tip size of 1 1/2” nozzle attached

29
Q

For optimum effectiveness of TL streams, supply water to base of TL at?

A

200 – 250 PSI

30
Q

For optimum effectiveness of TL streams, relief valve of TL should be set at?

A

250 PSI

31
Q

For optimum effectiveness of TL streams, generally how many sources of water at base of TL?

A

generally, only 1 source (relay pumper can take water from more than 1 source)

32
Q

For optimum effectiveness of TL streams, relay pumper adjacent to a TL should have in excess of ______PSI intake pressure with water flowing. This way, the relay pumper can operate in _________ position and still deliver close to _______PSI

A

80 PSI / Volume / 250 PSI

33
Q

For optimum effectiveness of TL streams, when necessary to shut down or to regulate pressures, do so where?

A

At the relay pumper and not at the TL based gated siamese

34
Q

Which end of the 3 1/2” hose do you stretch to the TL?

A

Male end

35
Q

Nozzle pressures of the TL basket should not exceed _______PSI with the relief valve setting of _______PSI?

A

100 PSI / 250 PSI

36
Q

For overhaul, where should the TL basket railing be positioned?

A

slightly below work area

37
Q

4 things TL bucket should not be use for or done:

A

1) force timbers or cornices back into building or onto roof – 2) pull/push objects – 3) as a derrick (pivoted beam to lift/move heavy objects) – 4) not rest TL basket against building wall

38
Q

When cutting cornices from a TL bucket, what two tools are added to the normal compliment of tools?

A

power saw/bolt cutters

39
Q

Metal hangers of cornices should be cut when?
