It can be argued that the fire ground placement of aerial apparatus is the ______ of all types of apparatus
most critical
It is Crucial to give the optimum scene position to the aerial apparatus than to the pumpers
True or false
True
It is important that the driver operator be versed in the ________ so that they can apply them when faced with a particular situation
basics of proper positioning
Later arriving aerial apparatus at large incidents will be positioned according to the __________developed at the scene by the incident management personnel
incident action plans
If the fire building is less than five stories about 60 feet engine companies should park on the _____and aerials park on the ______.
side of the street closest to the building
Outside
If the building is greater than five stories, the engine should take the ____ position and Ariel park ___ to the building
outside
next
For any given situation the proper distance between the subject and the aerial apparatus is the distance that affords maximum stability best climbing at angle and allows for adequate extension
True or false
True
_______Extensions at____Angles place the maximum amount of stress on an aerial device and in some cases reduce the load caring capacity of that device. Whenever possible ____ extensions at ____angles should be avoided.
Long
Low
Long
Low
If the building has been exposed to severe fire conditions or has otherwise been weekend, it is not desirable to park ______ to the building.
too close
_______Are the factors that work against the strength of the aerial device
Stresses
Stress may be imposed in both_______ and________operation. The stress tends to be greater when the aerial device is in motion
Static- at rest
Dynamic- in motion
There are four main tactical uses for any aerial device.
– Rescue
– Access to upper floors
– Ventilation
– Fire suppression
The best rescue approach is made from________.
Up wind
If possible, aerial apparatus used for rescue should be placed at the _______of the building, this allows the apparatus to reach victims on______
Corner
Two sides
If a rescue is to be made from an aerial threatened by fire, ______ can be used to protect victims, rescuers, and the aerial device
hose lines
Solid bore or straight stream master streams directed against an aerial device can place_________Load stresses on the device that could ultimately result in a________Of the device.
Damaging
Collapse
If victim is to be lifted over the top rail, the apparatus should be placed so the turntable is ______ with the target. This allows the front of the platform to be placed squarely in front of the target.
directly in line
If the victim will be allowed to enter the platform through the hinged gate, the turntable must be spotted a little _____ The target.
forward or behind
In some cases, it is ______ to latter the building on the side opposite the fire conditions.
advantageous
Proper placement of the aerial device can make the ventilation process _______.
quicker and safer
If the aerial device is being used to provide access for ventilating a pitched roof, it may be possible to position the apparatus so that the firefighters may operate directly from the aerial device. This is beneficial in the event that a _____ occurs.
sudden roof collapse
When providing access for ventilating a flat roof, the aerial apparatus should be positioned on the ______of the structure, as close as possible to the area of being ventilated.
unburned side
Extend aerial ladders at least______ above the roof level.
6 feet
If the aerial apparatus is being used to assist with the horizontal ventilation such as taking out a window. The turntable should be positioned ______ will be upwind of the ventilation points and will have access to as many windows as possible.
so that the entire aerial device
All ventilation activities must be performed in a _____ ______ with the incident plan established by the IC.
coordinated manner consistent
Warning external fire attacks with master stream ______ be performed when crews are working inside the building the disturbance of the interior thermal balance, the large volume of steam created the possibility of being struck by the stream any additional weight added to the building by external master stream attacks pose a serious safety threat to firefighters working in the building.
must never

building collapse.
The ______ conditions of the spotting area must be considered when using an aerial device.
surface
If working on soft surfaces, operators must watch for settling.
True or false
True
Be alert for surfaces that are stable when the incident begins but which may become ______ as the instant progresses
unstable
