Chapter 20 Flashcards
_______ _____represent the overall plans needed to successfully Mitigate and emergency and terminate an incident
OPERATIONAL STRATEGIES
–The actual procedures and actions taken to successfully carry our strategies
TACTICS
In situations that require using aerial apparatus for rescue, the main objective is to to reach as many victims or points of egress as possible with a
minimum number of aerial movements
The level of victim rescue priority from highest to lowest are
1• most severely threatened by conditions of
the hazard
2• largest number of groups of people
3• remainder of people in the hazard area
4• people in exposed areas
In situation that required aerial rescue who should be given the highest priority
Those who are in the greatest amount of real or perceived danger
When two or more groups of victims appear to be in the same amount of danger,which should the aerial device extended to
The larger of the two groups
The driver should try to keep the aerial device _____to the victim
Perpendicular
When rescuing a victim through a window using an aerial ladder the first rung of the ladder should be placed
Even with the windowsill
When using aerial platform, most fire department prefer that the platform be placed so that the top rail of the platform
is even with the windowsill
When removing trapped victims from the roof (or similarly open, flat areas)the tip off the aerial ladder should be_____ above the edge of the roof
Extend at least 6 feet
Aerial platform should be place so that the bottom of the platform is just above and over the edge of the roof
true
When breaking windows to provide cross ventilation, position the aerial device
Slightly above the window to the upwind side
Water add weight to the structure at a rate of
2,000 pounds for every 250 gpm
A more common use of elevated master streams is in
Defensive operations
Exterior fire attack that is limited to controlling the spread of a fire, with an emphasis on exposure protection.
Defensive attack
IF THE AERIAL LADDER IS DESIGNED TO BE USED IN THE UNSUPPORTED POSITION, THE TIP SHOULD BE PLACED____TO KEEP IT FROM CONTACTING THE BUILDING
ABOVE THE TARGET SPOT
APPARATUS DESIGNED TO BE USED IN A SUPPORTED POSITION,____WITH THE SUPPORTING OBJECT
BOTH BASE RAILS ARE EVENLY IN CONTACT
ONCE AN AERIAL IS IN PLACE FOR A RESCUE ENGAGING THE_____ ___ IS AN IMPORTANT STEP IN MAKING THE DEVICE A RIGID STRUCTURE. THE EXTENSION LOCKS _____ THE OVERALL STRENGTH OF THE EXTENDED DEVICE AND GREATLY ____ THE CHANCE OF FAILURE
EXTENSION LOCKS /INCREASE /REDUCE
I carefully placed solid or straight master stream from the exterior of the building is often referred to as
BLITZ ATTACK
the best way to effect a blitz attack with an elevated master stream is to
deflect water off the ceiling of the fire room
water deflection can be accomplished by positioning the aerial device so that the nozzle is about even with the bottom of the_____. this position allows water to enter the area at an angle of about ____. if too large of an entry angle is used, water will hit the ceiling ahead of the fire area and Cascade to the floor
window / 30 degrees
water add weight to the structure at a rate of 2000 pound for every
250 GPM
on aircraft rescue ladder should be positiond to the
aft (rear) of entry doors
under working condition, the driver must know how to communicate
effectively
Elevated master stream are most commonly used in
Defensive operation
Aerial device are not designed to handle
Excessive lateral stress
The best way to effect a blitz attack with an elevated master stream is try to
Deflect water off the ceiling of the fire room ( water should enter the window at an angle of 30°)
If a victim should enter the platform through the hinge gate the turntables must be position
A little forward are behind the targe ( because the gate typically on the side of the platform)
Parapet wall
Vertical extension of an exterior wall and sometime interior firewall
