The placement of aerial ladder apparatus (tractor-trailer and rear mount) is dependent on four conditions:
Whether immediate rescue is apparent.
Where no immediate rescue effort is required, the size of the frontage of the building to be covered in case of future need.
Smoke, heat or fire causing an exposure that would endanger a victim, a member or the ladder.
Area or street conditions that might hamper optimum positioning.
Two methods that may be used to attain accuracy in lining up the ladder with a window are:
A. For the experienced member, accuracy will be obtained by sighting ______________________________________.
B. For the less experienced member, this accuracy will be attained by sighting ________________________________________.
A. along the ladder rail of the top section.
B. along the underside of the ladder beam on the top sliding section.
Recommended distance of the tip from the objective is ________.
In case of rescue, use the ___ positioning so that the ladder will rest against the window sill after weight is put on it.
There is an exception to this recommended minimum distance. At a very extreme angle, e.g., placing the ladder to the roof of a seven story building, allow the ladder to _____________________________.
When positioning a ladder at a window, the placement must allow for unimpeded access and egress at this window. Therefore, the ladder tip should be __________________ the window sill.
2” to 6”
2”
barely touch the building
less than 6” over
Severe fire - People on the fire escape above the fire.

Place the ladder alongside the fire escape with the tip 2” away from face of building and about one to three feet above the balcony railing.
Severe fire - Large Frontage Building (over 30’) - No people showing.
If no condition exists in front of building, requiring a definite position, place the center of the turntable approximately ___ from the side wall passed on your approach
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
At vacant building fires, officers of aerial ladder companies shall consider the need for access and positioning of tower ladders in order to utilize their extinguishing capabilities. However, there are vacant building fires where the officer gives precedence to the positioning of their aerial apparatus, e.g.
A. A building not completely vacant.
B. The officer receives information or has prior knowledge that part of this building is used by vagrants or squatters.
C. The reach of the 100’ aerial is required to expedite or execute certain tasks or assignments.

INTERIOR STAIRS
HORIZONTAL EXITS
FIRE ESCAPES
LADDERS
LIFE SAVING ROPE
If possible, chauffeurs should avoid running over the hoselines. When necessary, it should be a __________line, and it must be done ___________.
charged line
Slowly
Ladder chauffeur should remain on turntable when members have entered the building by aerial ladder and are in precarious positions such as:
a floor over a heavy fire
the roof of a building with a heavy fire condition, etc.
When placing the ladder to the roof, extend the ladder so that the tip is at least 5 feet above the point where the ladder comes in contact with the building.
tip is at least 5 feet above
Reasons for laddering the roof are:
The fire building is isolated and roof ventilation is required.
Other means of access to roof of fire building are unavailable or cut off and roof operations are evident whether for ventilation or rescue.
As a means of escape for operating force or civilian(s) guided by member(s).
Any other situation where its use would significantly improve operations.
To remove ice, first free
- rungs and ladder rung locks
- the trussing
- and then the main beams.
Members at the pedestal position shall ensure the following safeguards and actions are taken BEFORE placing aerial into operations:
A. The area immediately around the turntable be designated a Danger Zone. (Turntable Platform)
B. Danger Zone around turntable be clear of members, tools or any impediments before rotation of aerial.
C. If a firefighter is to climb the aerial ladder at the start of an operation, he or she shall be in position on the turntable before the aerial ladder is to be raised and rotated.
Members of Ladder 200 were drilling on “numbers” in the bulletin on aerial ladders because they know numbers and colors are on every promotional exam. Which choice below is least correct?
A: Less than thirty feet frontage of a building would be considered a narrow frontage building
B: Thirty feet or more would be considered a large frontage building
C: The average city sidewalk is 13 feet from the building line to curb and 35 feet from curb to curb
D: When placing the ladder to the roof, extend the ladder so that the tip is at least 5 feet above the point where the ladder comes in contact with the building
B. Buildings OVER 30 feet in width are considered large frontage buildings. 3.5
Explanation:
A. A narrow frontage building is 30 ‘ or less in width. Aerial Ladders 3.4
C. 3.1.1
D. 7.13
