What is the ideal situation for best rescue on an aerial apparatus
Approach is made from upwind on level grade and without obstructions
196
What are the two advantages by positioning an aerial apparatus, for rescue, at the corner of the building
You can potential he reach victims on two sides of the building You are potentially safer on the corner if a structural collapse occurs
197
What is the preferred stream used to cool and protect the aerial device and personnel while the rescue operation is in progress
Wide angle fog stream
198
When rescuing a victim, on an aerial platform, what is the correlation in the position of the apparatus and how the victim is rescued
apparatus must be directly in line with the target If the victim is to be rescued through the hinged gate, The turntable must positioned a little behind or forward the target because the platform gates are typically on the side of the platforms
199
In situations that require using aerial apparatus for rescue, the main objective
Is to reach as many victims reports of egress as possible with a minimum number of aerial movements
200
Rescuing victims from an aerial apparatus what is the priority from highest to lowest
Most severely threatened by conditions of the hazard Largest number of groups of people Remainder of people in hazard area People in exposed areas
201
Rescue situation determining which victim is in the most danger is a judgment call made by who
Incident commander Truck company officer Aerial apparatus driver /operator
202
Typically in a fire,who is going to be in the greatest danger to be rescued by an aerial apparatus
Occupants located on or immediately above the fire floor will be of the greatest danger
203
Is someone in a panicked state considered to be of high importance to be rescued by an aerial apparatus
If a panic person is ready to jump they are of high priority to be rescued but not be rescued over someone that is in great danger if the panicked person is in a safe location
204
should victims in a hazard area or people in exposed area of a multi story building that is on fire be rescued by an aerial device
Some judgment should be used to determine whenever or not the victims are in enough danger to work evacuation by an aerial device
205
When maneuvering an aerial device to reach a victim trapped in elevated position, the aerial device should initially be aimed ( above or below) the victim and then (lowered or raised)
The aerial device should initially be aimed above the victim and then lowered to keep the victim from jumping on the ladder before in the proper position
206
When victims board the ladder, their weight will cause the ladder to flex, and proper positioning will prevent the beam from contacting the object. If a beam is contacting the objective, what could happen
The weight of the victim can cause the opposite beam to bend downward, which could twist or bend the latter, causing catastrophic failure
207
Once an aerial device is in place for rescue,___________. ________________ should be engaged and is an important step in making the device a rigid structure if so equipped
Extension locks
208
When using an aerial ladder to rescue from a window, _______ rung of the ladder tip should be placed even when the windowsill
First rung
209
When using aerial platforms, most fire departments prefer the platform be placed so that ___________________ of the platform is even with the windowsill
Top rail
210
When removing trapped victims from a roof, the tip of the aerial ladder should be placed so least _____ feet extends above the edge of the roof
6 feet above roof for ladder
211
Aerial platforms should be placed so that the bottom of the platform is just ________ and _________ the edge of the roof for rescue from a roof
Above and over
212
What may be necessary to use to traverse a tall parapet wall
ground laters
213
When moving victims down an aerial ladder what is the desirable method of movement for heavier person who is conscious and able to control his or her own movement but not strong enough to descend under his or her own power
Knee sit method
214
What are some safety issues or concerns when using an aerial device for water rescue
First safety issue is often the lack of a suitable location to adequately stabilize the apparatus - another concern is the potential for the aerial device make contact with swiftly moving water - lastly On aerial device they have a low tip load rating when fully extended to a horizontal objective, it is difficult to perform such a rescue without dangerously overloading the aerial apparatus
215
What makes the location of the latter plainly visible to firefighters on the roof, even in a smoky condition, when using an aerial ladder for ventilation
To extend the fly section so that a minimum of 6 feet protrudes over the edge of the roof
216
When using an elevated platform for vertical ventilation, which position allows for firefighters to easily exit and enter the platform
Position even with or extended Ceiley over the roofs edge
217
What is most commonly used in a defense of operation
Elevated master streams
218
If the IC makes the decision to apply water from an aerial master stream, the driver/ operator needs to know what three thing
Volume to be delivered Type of stream to be used Placement of the stream
219
External master stream attacks pose a serious safety threat to interior firefighter crews by which four things
- disturbing the thermal layer - creating large volumes of steam - The possibility of being struck by the stream - additional weight imposed on the building from water
220
For foam streams, which is generally not practical to discharge from elevated master stream appliance
Aerated foam
221
Define blitz attack
To aggressively attack a fire from an exterior with a large diameter fire stream
222
What's the best way to effect your blitz attack with an elevated master stream
To try to deflect water off the ceiling of the fire room Position aerial apparatus so the nozzle is about even with the bottom of the window and allow water to enter the fire area and an angle about 30° at the ceiling
223
Define defensive attack
Exterior fire attack that is limited to controlling the spread of the fire with an emphasis on exposure protection
224
Indicators of a potential defensive attacks are
fire or building conditions that prohibit safely advancing hand lines into the building - The incident commander ops to sacrifice part of the building to the fire - large amounts of water needed to extinguish the fire such as common attics or multiple apartments
225
In a defense of fire which stream is the most commonly used by an aerial apparatus
Solid or straight stream will be required to reach the seat at the fire
226
Can an aerial apparatus used as an exterior standpipe to upper floors
Yes | Can eliminate difficult hose lays up interior stairwells
227
Using the aerial as an exterior standpipe is also as an affective tactic for the following
- fires in parking Garages - fires on building roofs - fires on bridges or overpasses - fires in buildings under construction where the standpipe system is not available
228
Fire spreads to exposures either by conduction, convection or radiation, conditions that may affect exposure hazards include the following
``` weather Fuel Topography Building construction Spacing between the fire building and the exposure Intensity of the fire ```
229
For exposure protection with a elevated master stream, what are some advantages and disadvantages to using a fog pattern
Allow for maximum coverage of the exposure The fog stream may not work due to Highwinds, excessive distance, excessive heat
230
