Ladders 2 AL Flashcards
Placement of AL dependent on “FISHS”
Frontage size where no immediate rescue effort,
Immediate rescue apparent,
Smoke/Heat that would endanger victim/member,
Street conditions hampering optimum positioning
_ shall assist LCC in proper placement of rig before carrying out duties.
Rig shall not be backed up unless LCC _
OV (CR: Brownstone specific tactic Roof FF shall assist LCC)
LCC has assistance of at least 1 guide man
Place AL _’ from building for a good climbing angle (avg city sidewalk is _’ from bldg line to curb & _’ from curb to curb)
25-35’
13’
35’
2 Methods to attain accuracy in lining up ladder w/window: Experienced member vs Less Experienced member
Experienced= along ladder rail of top section “Rusty FF= Rail”
Less Section = beam on top sliding section
“Bop= Beam”
Recommended Distance of tip of AL from objective is “-”. In case of rescue _”. Exception:
2-6”
2”
Very Extreme angles allow ladder to barely touch bldg
Positioning AL at window- ladder tip should be less than _” over window sill
AL alongside fire escape & against the bldg (_” out) w/tip about _’ above balcony railing
6”
2” out
1-3’
Narrow frontage bldg (30’/less width) w/NO people showing, place AL _
Large Frontage bldg (over 30’) w/NO people showing _
Turntable in center of bldg & ready truck for raising the ladder
Center turntable approx 15’ from side wall passed on approach
Can venting of windows be effected by exerting lateral pressure w/AL
Under NO circumstances
Using AL to vent windows
Aim at upper window panels just above the sash w/o hitting the sides or tops of window frames. Avoid striking ceiling & lower ladder to crack horizontal wooden sash
When removing victims w/AL and chocks & tormentors need to be set, have OV take the _ side
Outboard side (allows OV to observe bldg) & another FF to inboard side
Can AL be moved w/Firemen & victims on it
How shall FF descend AL w/victims on it
Only in an extreme emergency (direct exposure to flame & heat)
1 rung below rung victim is standing on in unison. At Steeper angles have victim grasp rungs looking ahead (NOT down)
Removal from AL NOT considered complete until _
Serious fire in rear, cutting off interior descent & NO available front fire escape remove _
Assisted all the way to the ground. Do NOT leave at Turntable
Simple removal 1st then concentrate on difficult removal
Serious fire in front might cut off ladder descent in short period of time. 1st assist “FFFF”
Fire Front Fat guy First: Most helpless 1st, then move to ambulatory
When more than 2 people need to be rescued Off should _
Off should contact 2nd Ladder & inform them of the need for supportive assistance
5.12
3 Scenarios where AL preferred over TL in Vacant bldg fires
Bldg NOT completely vacant,
Prior knowledge that part of bldg used by Vagrants/Squatters, &
Reach of 100’ AL req’d for certain tasks
When approaching a box location & there’s NO visible indication of fire on avenue of approach _
LCC should slow down 1 intersection short of box location & enter intersection at a slow rate of speed.
When an AL is committed to roof & is only safe egress from roof, can it be moved
Only if absolutely necessary & direct radio comm made w/FFs on roof (Must also be evident NO immediate need for roof egress & new task will NOT delay prompt replacement of AL at original location)
Ladder Pipe Ops: if street has a severe crown, make sure ladder angle does NOT exceed _ degrees
Recommended water supply from _ source(s)
Interior forces removed.
Warning shall be _
70 degrees
2 supply sources
Horizontal sweep w/stream without stopping
When placing AL to roof- extend ladder so that the tip is _
If fire is in “H” type & conditions do NOT mandate a specific position place AL _
At least 5’ above where ladder comes into contact w/bldg
Avoid blocking front entrance to courtyard when it’s apparent TL may operate at that location
Place Inboard side of AL not more than _’ from building line
_ is the 1st step in AL collapse
35’
Twisting
Causes of AL collapse “TWITH”
If AL becomes coated w/ice- Defrost by 1st freeing “Rudy Loves Tommy Boy”
Turntable not directly opposite objective, Windy, Ice, Twists, Hilly location
Rungs, Ladder rung locks, Trussing, & Beams
When Ice prevents LCC from raising AL away from bldg, the hydraulic mechanism can be assisted by _
At high angles consider using _
Placing a PL under extended lad & using FF to exert add’l pressure.
Utility rope tied near tip w/FF on roof/in window of bldg across the street to pull rope taut
Can the De-icing valve be operated by members on AL
Can AL be moved w/ladder raised to one side
Only under Supervision of Dept Mechanic
Never
Danger Zone of AL
Area immediately around TT (TT Platform)
Incorrect positioning rear mount AL
A. Place rig 25-35’ from bldg for good climbing angle
B. Avg city sidewalk is 13’ from bldg line
C. Avg city street 35’ from curb to curb
D. Due to visibility restrictions of a closed cab (rear mount or tractor trailer) Off or Roof FF can assist Chauffeur with initial placement of rig
D Off or OV
Least correct AL
A: Wheel chocks should be placed to prevent movement of the apparatus. Carry one set of chocks on each side of the apparatus
B: Place the inboard side of the apparatus not more than 35’ from the building line
C: For unobstructed climbing of the aerial ladder, align the rungs. This is accomplished when the rung alignment indicator light is illuminated
D: Use the life belt when operating on the aerial ladder
D. Use the Personal Harness when operating from the aerial ladder. 8.11 This was changed on 1/15/14
B. 8.6
C. Added to the books on January 15th, 2014. 8.5
***Evolution 22 still mentions the life belt when stretching a line up an aerial. Be aware of this conflict, if the examiner goes to that subject.
For a severe fire with no people showing and no fire condition in the front of a building over 30 feet wide, the LCC of an aerial ladder shall place the center of the turntable approximately _ feet from the side wall passed on approach. A: 5 feet B: 10 feet C: 15 feet D: 20 feet
C. If no condition exists in front of building, requiring a definite position, place the center of the turntable approximately 15’ from the side wall passed on your approach.
Aerial ladders 3.5.1
The placement of AL apparatus (tractor-trailer and rear mount) is dependent on four conditions. Which of the following choices is not correct?
A: Whether immediate rescue is apparent
B: Where no immediate rescue effort is required, the height of the building to be covered in case of future need
C: Smoke, heat or fire causing an exposure that would endanger a victim, a member or the ladder
D: Area or street conditions that might hamper optimum positioning
B. Where no immediate rescue effort is required, the size of the frontage of the building to be covered in case of future need.
Aerial Ladders 2.1
Incorrect during AL ops
A. When both stabilizers are properly in place, both STABILIZER DOWN green lights will be illuminated
B. Wheel chocks should be placed to prevent movement of the rig. Carry one set of chocks on each side of rig
C. At night, keep the top of the lad & rungs well illuminated. For greater visibility, units could place reflective tape on the tip of the lad & paint the tip white or yellow
D. For extended ops or when the turntable will be left unattended, disengage PTO in order to prevent accidental movement of ladder
C All AL tips are now painted orange
8.3
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 TB App L-7
5.4.1
AL ordered to setup Ladder Pipe on a street with a severe crown. Off insures LCC checks both Inclinometers & _
A. Both of the bubbles are in the green zone. If in the red zone, the rig must be repositioned
B. At least one of the bubbles is in the green zone, otherwise the rig must be leveled or repositioned
C. At least one of the bubbles is in the green zone, otherwise the rig must be leveled
