Q
  • Raising the aerial for victim rescue
A
  • Perpendicular is the best ( reduces twisting/torsional stress)
  • 70 to 80 degrees preferred (max loading)
    50 to 60 degrees is easier
  • Raise ladder above victim then lower

200 lb victim jumping 3 ft = 700 lbs of force

17
Q

Tire placement for ladders during operations are

A
  • Front tires must be in contact with the ground

- Rear .5 to 1 inch off the ground

18
Q

Window rescue

A
  • Aerial Ladder
    place tip with the first rung even w/windowsill
    4-6 inches off the off the objective
  • Aerial Platform
    place the top rail of the platform even with the bottom sill
19
Q

Defensive operations

A
  • all firefighters must be cleared and out of the structure

- every 250 gpm will add 1 ton of weight every minute

20
Q

4 Tactical uses for aerials

R,A,V,F

A
  • Rescue
  • Access to upper floors
  • Ventilation
  • Fire Suppression
21
Q

Stabilizer for sticks will only correct how many degrees

A

-3 degrees of slope and grade for sticks

22
Q
  • Aerial apparatus construction
A

3 main portions
( base, top rails, rungs )

  • no section narrower that 18 inches
  • rungs placed 14 inches on center
23
Q

3 types of ladders

A

1) Aerial ladders
2) Elevating platforms
- Telescoping
- articulating
3) Water towers

24
Q

Rotate
Extend

25
Q

Aerial ladder operation order from platform while bedding

A

Retract
Rotate
Lower

26
Q

Ladder position for VENT

A

Sticks
ROOF: 6 ft above the roof
Window: tip at the top of the window on the windward side

Platform: even or just above the roofline

27
Q

Ladder placement for BLITZ attack

A
  • NOZZLE even with the sill 30 degrees
28
Q

Stabilizer Pads

A
  • 150 PSI without pads

- 75 PSI with pads

29
Q

PLATFORM ladder set up time

A

LESS than 110 (stabilizer set)- required to be raised-rotated 90 degrees in 150 seconds or less

30
Q

STICKS ladder set up time

less than 110 ft

A

LESS than 110 (stabilizer set)-required to be raised-rotated 90 degrees in 120 seconds or less

31
Q

STICKS ladder set up time

greater than 110

A

Greater than 110 (stabilzers set)- required to be raised roatated 90 degrees in 180 sec or less

32
Q

Stabilizers
L-13
L-21

A

100%

  • 0 to 5 degrees SLOPE
  • 0 to 5 degrees GRADE
                                            50%
  • 5.1 to 8 SLOPE
  • 5.1 to 8 GRADE
33
Q

Stabilizers

STICKS

A

full load 100%

  • 0 to 3.5 side to side (slope)
  • 0 to 5.5 front to rear (grade)
            reduced capacity   50%
  • 3.6 to 5.5 side to side to side (slope)
  • 5.6 to 6.5 front to rear (grade)
  • when angles are greater that 5.5 slope or 6.5 grade do not operate the ladder
34
Q

Tip control speeds

A
  • operates 1/4 the speed that the turntable
35
Q

What is the greatest stability while ladder is set up

A
  • operating the aerial on the longitudinal axis of the vehicle will offer the greatest stability. (ladder will be over the front or the rear of the cab)
  • operating the aerial perpendicular to vehicle creates less stability
