Ch. 20 Aerial Apparatus Strategy and tactics Flashcards
Ch. 20 pg. 719.
Operational strategies represent the overall plans needed to successfully mitigate an emergency and terminate and incident. Operational strategies will depend on prefire plans, prearrival information, and initial size-up of the incident. To successfully achieve these strategies firefighters must:

B. work as a unit, not to freelance on the incident.
C. be able to communicate effectively and perform certain tactics.
D. must train on current tactics for multiple situations.
C. be able to communicate effectively and perform certain tactics.
Ch. 20 pg. 723
What is the priority considerations for rescue:
most severely threatened by condition of the hazard
largest number of groups of people
remainder of people in the hazard area
people in exposed area.
Ch. 20 pg. 727
When setting up for a rescue from a window in a platform device, What is the preferred placement?
top rail of the platform to be even with the windowsill, this allows the victim to board directly feet first.
alternative, is to place platform gate even with windowsill to board through the gate.
Ch. 20 pg. 736
Aerial devices can be used for multiple types of rescues, building rescues, rope rescues, water rescues. When setting up for water rescue what is the first safety issue that affects aerial apparatus:
Lack of a suitable location to adequately stabilize the apparatus.
in many cases the ground is muddy or otherwise unstable, and will not safely support the weight of the apparatus.
Ch. 20 pg. 742
When elevated master streams are used in a blitz attack, they should only be flowed long enough to darken down the fire. The water adds weight to the structure at the rate of ______ for every ______.
When possible, find avenues of__ from the building when using Master streams during fire fighting operations.
2000 lbs
250 gpm.
Drainage
Ch. 20 pg. 745-746
Keep in mind the apparatus is also an exposure. When protecting exposures from radiant heat, the water stream needs to be __________. protecting from convective fire spread, the fire stream should _______.
applied directly onto the exposure surface.
fog stream should be directed into the thermal column.
Ch. 20 pg. 748
Aerial apparatus may support operations involving aircraft rescue and fire fighting (ARFF) incidents. a first option for rescuing victims, all larger commercial passenger aircraft and some military aircraft are equipped with escape chutes and slides. The second best option is to place a set of portable stairs at the exit doors. an aerial device should be raised to:
in an aircraft exit opening should follow principles for performing window rescue. or if placed to the lead edge of the wing, follow procedures described fro rescues from a roof.
p.721 Access to Upper Levels
+Apparatus position should provide for the maximum degree of safety and access to the building to the firefighters using the aerial device.
+When using the aerial device in this function, it should not be repositioned unless the change is communicated ___ and ___.
+Using aerial for equipment delivery saves FF’s __ and __ from carrying equipment up stairs.
Effectively and Acknowledged
Time and Energy
p.721 Rescue
+When fire conditions do not allow victims to be brought down interior stairwells or exterior fire escapes, may be necessary to use__ device.
+Ideal situation, best rescue approach is made from__ on level grade and without obstructions.
+Turntable is upwind of target.
Aerial
Upwind
+If possible, position aerial on corner of building
-Reach 2 sides and safer from collapse
p.722 Rescue
+If a rescue is made from area threatened by fire, __ can be used to protect victims,rescuers, and aerial device but caution must be used when selecting the fire stream for the lines.
Hoselines
+Preferred procedure=wide angle fog stream to cool/protect the aerial device and personnel while the rescue operation is in progress.
p.722 Rescue with Aerial Platform
+The plan for getting a victim into an aerial platform will determine placement of apparatus.
+If Victim to be lifted over top rail:
-Position apparatus so turntable is directly in line with target, this allows the front of the platform to be positioned __ in front of the target.
+If victim enters platform through hinged gate:
- Turntable must be positioned a little __ or__ the target because the gates are typically on the side.
- Device must be raised at an angle to the target to provide safe access to the gates.
Squarely
Forward or Behind
p.722 Priority Considerations
+Main objective is to reach as many__ or points of __as possible with a minimum number of aerial movements.
Victims
Egress
p.723 Highest priority for Rescue
+Those who are in the Greatest amount of __or__ danger should be given highest priority.
+Typically occupants__or __ fire floor will be in greatest danger.
Real or Perceived
On or Above
+Visible fire conditions will be strong indication
+Rescuers should give preference to Panicked or appear ready to jump(can be people who are not in the immediate fire area)
+FF’s should NOT pass up those in greatest danger to rescue panicked person in safe area.
p.723 second priority of rescue
+largest group of people
+When 2 more groups appear to be in same amount of danger, the __ of the 2 groups should have aerial device extended to them first.
+Worst case scenario, best to rescue largest number of people possible, given the __ available.
Larger
Time
p.723 Third Priority for Rescue
+Remainder of people in the fire area.
+Remaining groups of victims should be removed in order of the next most threatened by the___.
+During this process, The D/O and/or CO should continue to__ fire conditions for changes that might increase the danger to any waiting victims.
Hazard
Monitor
p.723 Fourth Priority for Rescue
+People in exposed areas.
+Once all who appear to be in immediate danger have been removed, other victims who are unable to escape the fire building or__ by standard methods should be evacuated next.
Exposures
P.724 Changing Priorities
+The D/O should always be alert for __ fire conditions during rescue operations.
+Possible that victims who did not appear to be high priority when operations began could suddenly become top priority due to__ growth and spread or smoke penetration in their area.
Changing
Fire growth
p.724 Raising Aerial Device to Victim
In the perpendicular position, twisting stresses imposed on the aerial are reduced.
In older apparatus designed to be used in the supported position, perpendicular positioning allows for:
+Aerial Ladder designed for Supported Position
-Perpendicular Position allows for Max load carrying capabilities when both __ rails are evenly in contact with the supporting object.
maximum load carrying capabilities
Base
+Aerial Ladder designed for Unsupported Position
-Tip should be place above target spot, this placement prevents ladder from contacting the building without placing excess stress on device.
p.725 Raising Aerial to Victim
+Optimum positioning not possible and aerial ladder must be extended toward the object at an angle.
-Extend the ladder so that the __ on the building side of the ladder is above and over the objective. This will prevent the beam from contacting objective when victims board the ladder.
+If a beam is contacting the objective, the weight of the victim can cause the opposite beam to bend__ which could twist or bend the ladder, causing ___ failure.
Beam
Downward
Catastrophic
p.725 Raising Aerial to Victim
+To reach victim in elevated position, the aerial device should initially be aimed__ the victim then__.
-Putting ladder below may cause victim to jump onto ladder.
+Once in place for rescue, engaging the __ locks is an important step in making the device a rigid structure, these greatly increase overall strength of the extended device and greatly reduce chance of failure.
Above then lowered
Extension locks
p.727 Positioning Aerial Device for Rescue from Roof
(or similarly open, flat areas)
AERIAL LADDERS
+Tip of aerial ladder placed so that at least __ feet extends above the edge of the roof.
AERIAL PLATFORMS
+Placed so that bottom of platform is just __ and__the edge of the roof.
*This position allows victims to have a __ while climbing onto ladder or into platform.

p.728 Moving Victims Down Aerial Ladders
+At least 1, preferably 2 FF should be assigned to assist the victims.
