Flashcards in Ch. 7 Ladder Company Ops Deck (49):
Having a plan does many things (Ladder Company Ops): (3)
1. Formalizes THINKING (consider in advance what must be done)
2. Assigns degree of PRIORITY to each element
3. Establishes ACCOUNTABILITY for one's actions (who does what)
LOVERS U stands for:
Rescue and search
Operational plan is general but should provide these specifics: (Ladder Ops) (3)
1. Number of PEOPLE committed to major areas
2. TOOLS to be provided to major areas
3. General SCOPE of duties
3 basic tools at almost all structural fires:
Forcible entry bar (halligan)
Hook or pole
Chauffeur operates on perimeter as long as he maintains contact with: (3)
Factors for member operating alone:(3)
1. Experience level
2. Availability of radios
3. Mutual understanding of needs of each task (highly desirable)
Following factors affect selection and placement of portable ladders: (5)
Material of construction.
Number of personnel required to place.
Rules for aerial ladder to roof (2)
*placed As Square to Building As Possible
AT LEAST 5 rungs above level of roof
Ladder "inch or two" from building
Platform (basket) to roof (4)
*member in basket can place it in best location
No parapet = resting on roof
Moderate height parapet (3-6 ft) = top rail just SLIGHTLY above top of parapet
High parapet (more than 6 feet) = relocate
- if not possible, access directly from bucket
- attic ladder from top sliding section of boom
(Platform) Basket to window (4)
Close to bldg as possible, basket in line with window
Front corner of basket at window
Top rail level with window sill
Forget about gates
Aerial ladder to window (2)
Turntable in line with window/objective - Perpendicular
Tip just BELOW the window sill
Aerial ladder at angle to roof dangers
Torsional load and shock load
Scrub area determines:
Width and height apparatus may be expected to cover for:
access, egress, platforms, application of streams
Aerial ladders and telescoping booms have _________ than articulating booms
Greater scrub areas
Perfect distance for maximum scrub area depends on: (2)
Length of device.
Number of telescoping sections
Articulating booms scrub area and spotting distances determined by:
Length of bed section
Guidelines for apparatus positioning for all aerial devices:
Positioned for max benefit of device, common to see aerials blocked by engines.
Spot apparatus with fire's anticipated progress in mind.
In absence of specific requirements, Position apparatus 15 ft past corner you approached FIRST.
Aerial Safety Rules (2)
Keep all aerial devices 10 ft or more from overhead power lines.
Never extend/retract telescoping, aerial, ladder tower or tower ladder while person is climbing-if people exposed, rotate turntable or raising/lowering should provide relief.
No outward signs of fire and lacking a TIC: (what sense?)
Touch-Tricky, requiring caution and experience
Least used sense
-After ventilation, this sense can be useful in distinguishing between steam and smoldering ember.
Residential and commercial floor height
9 ft, 12 ft
Window sill height and window height
3 ft, 4 ft
Parapet heights and platform alignment
No parapet - resting on roof.
Moderate height parapet (3-6 ft) - top rail slightly above top of parapet.
High parapet (>6 ft) - relocate platform OR attic ladder to top sliding section of the boom
Of all the factors affecting ladder selection, whether purchasing or use, the single MOST important item must be its ______.
NFPA requirement for ground ladders (height)
Area of highest life hazard, REGARDLESS of time of day:
*odds very high*
Victims found in bedroom the great majority of the time
Young children in cribs
Older bedridden people
This person is responsible for working the front of the building
VES the front second floor bedrooms from the exterior.
Assigned a hook and a halligan
3 basic tools required at almost all structure fires
Flat head axe
Hook or pole
Proper placement and use of portable ladder in early stages of fire (3)
Prevent loss of life.
Cut off fire extension.
Make FFs task easier.
When selecting ladder for length, first consideration should go to:
Proper climbing angle for a portable ladder is about:
At 70 degree climbing angle, about ___% of total length is lost. The remaining ___% is called the _______.
To ensure proper climbing angle, quick estimate of height, divided by ______ gives you approximate location to place the ____ of the ladder away from the building.
Average residential window width:
FF w/air pack:
Lightweight aluminum ladder allows one person to handle most ladders up to ____, both straight and extension.
Heat indicating label on ladder will change color at _______.
Steep: climb w/great difficulty AND puts them in danger
Ladder may pull out from wall
Shallow: greater stresses on ladder
Makes climbing awkward
Precontrol vs postcontrol
Pre - while fire still has upper hand, under difficult conditions
*vertical voids, horizontal voids, floor directly over fire*
Post - less hurried, more detailed
*openings should be justifiable (senses)*
Three statements of caution when transporting items outdoors for final mop-up:
Items wet thoroughly and all visible flame extinguished.
Never allow partially extinguished in an elevator.
Avoid throwing smoldering debris out windows into areas that are Inaccessible or Out Of Sight of members outside.
Overhauling by "Logical sequence"
Fire room has been subject to flashover, with substantial damage.
First openings near existing holes.
5 senses used:
Smell (least used).
In a broad sense, action taken to expose hidden fire.
It's "PURPOSE" is to guard against rekindling of the fire after the department has left the scene.
Order of checking for void space: (3)
Floor above fire.
Poking just one hole into a ceiling at this stage can allow fire to blossom out uncontrollably into the room. (Senses)
15 second-2 minute rule.
Bare hand - 15-20 sec. With no discomfort.
Come back 2 min. later.
SSFO-it ain't hot chief
Particularly difficult type of ceiling.
Originally installed as fire retardant.
Begin at a seam.
Halligan most effective for this type.
Encompasses nearly every action on the fireground by both engine and ladder personnel.
Begins at the moment of arrival, if it is made a conscious part of each firefighters attitude.
