ch6 positioning aerial apparatus Flashcards
In many cases, the development of apparatus placemement procudures should be a function of?
preincident planning
Some fire dept establish an sop about apparatus placemnt based upon the height of?
the building at the scene
those factors that work against the strength of the aerial device
stresses
blank place the maximum amount of stress on an aerial device, and in some cases reduce the load carrying capacity of that device
long extenstion at low angles
the best approach of an aerial for rescue situations?
upwind, and if possible at the corner of the building
the preferred procudure is to use a blank fog stream to push the heat or fire away from the aerial while the rescue operation is in progress
wide-angle
placement of an apparatus with an elevating platform device will depend on?
how the driver-operator plans to get the victim into the platform
When positioning the aerial for access to upper floors it is often good to?
position the apparatus on the side of the building opposite the fire
when positioning the aeril device to ventilate a pitched roof it may be possible to?
position the aerial device to where the firefighters can work directly from the device
for ventilating a flat roof, the driver should position the aerial device?
On the unburned side of the structure as close as possible to the area being ventilated
when placing an aerial device for horizontal ventilation of windows the device should be?
slightly above and upwind of the windows with access to as many windows as possible
aggesive attack upon a fire from the exterior with a large diameter fire stream
blitz attack
exterior fire attach with emphasis on exposure protection
defensive attack
covering any object in the immediate vicinity of the fire with water or foam
exposure protection
when using the aerial device in a blitz attack position the aerial device?
to give the fire stream as much reach into the fire area as possible
elevated streams are most commonly used in?
defensive type of operation
blank refers to positioning the apparatus in a location that provides tha utmost efficiency for operating on the fireground
spotting
device that transfers the center of gravity of an apparatus and prevents it from tipping as the aerial device, hydraulic lifting boom, gin pole, or A-frame is extended away from the centerline of the chassis
stabilizer
unattached flat, metal plate that is larger in area than the stabilizer foot
stabilizer pad
vaults beneath the ground may be created by underground parking structures, utility chases, drainage culverts, basements that extend under sidewalks, or underground transportation systems
vaulted surfaces
blank are a good indicator of underground voids
manhole covers
method to remove ice from an aerial device
ice shrugging
when it is necessary to operate in high wind conditions, the driver should spot the apparatus in a manner
that require tha aerial device to be raised to the minimum extension needed, over the front or rear of the vehicle, preferably parallel to the wind
maintain a distance of blank feet between the aerial device and electrical wires
10
Stability of aerial apparatus can be improved by operating the aerial device
in line with the longitudinal axis
Ideally, the truck should be operated in the blank position with the aerial device directly in-line to reduce the stress
uphill
the maximum loading for any unsupported aerial device occurs when operated at angles between blank and blank from horizontal
70 and 80 degrees
Level blank staging is used on every emergency response when two companies performing similar functions are dispatched
one
level blank staging is used when numerous emergency vehicles will be responding to an incident
two
company officer of the first arriving company at the staging who takes command of the area and is responsible for communicating available resources and resource needs to the operations section chief
staging area manager
consider parking additional apparatus blank to blank feet behind the shielding apparatus to act as an additional barrier between firefighters and the flow of traffic
150-200
most railroad companies advise that vehicles be kept at least blank feet from the tracks when possible
