Emergency Ops Auto Extrication Flashcards
A victim delivered to a surgical team within _ of an accident w/critical injuries has the best chances of survival
Within the 1st hour (Golden Hour)
Can Airbags deploy after the battery has been disconnected
Yes airbags have an energy storage feature that enables them to be deployed even when the battery is destroyed in an accident
What does disconnecting a car battery do in terms of airbags that are mechanical & electrical
Starts drain time for electronically activated devices, but NOT mechanically activated ones
Treat all airbags as if they have NOT deployed. Follow 5-10-20 rule (explain)
Distance of at least 5” from side airbag, 10” from driver’s airbag, & 20” from passenger airbag
T/F Mechanically activated pretensiors in seat belts will remain live even after battery is disconnected
True Remove seat belt from patient ASAP
What kind of windows are being found in rear of newer cars
Laminated glass or plastics are replacing tempered glass. Presents formidable barrier in gaining access
Battery locations for cars
Under the hood, in wheel well, under seats, or in the trunk. Some vehicles may have more than 1 battery
T/F Transmitting a 10-75 for an emergency of multiple vehicle accidents w/numerous patients should be considered
True
Define Disentanglement;
Define Extrication
Removal of wreckage around victims;
Physical removal of victim from vehicle
During extrication where shall power unit be placed
Front or rear of vehicle. Allows responders to work on both side of vehicle w/o repositioning
Tools of choice for extrication
Spreaders & Cutters. Never position any part of body between tool & vehicle
Eng Ops at Extrication
Off divides into 2 teams. Off & 2 CFR FF’s w/Trauma bag & collars proceed to accident. Remaining members stretch & charge precautionary HL. Consider foam line
Lad Co Ops at Extrication
Positions discussed at roll call. Off & FE team proceed to accident for survey, chock, & access to victim. If NO EMS or Eng- stabilize patient.
Roof & OV- Hurst tool & equipment
LCC-Block traffic & bring add’l tools
Lad Off shall ensure disconnection of battery. Which terminal is removed 1st
Negative
Can FD right a vehicle w/a victim inside
How shall chocks be placed on vehicles w/all 4 wheels
Never
Place chocks just behind front wheel & in front of rear wheels step side down
_ is NOT req’d but allows vehicle to totally rest on chocks (Provides best stabilization)
Deflating tires
Vehicles found on side or roof should be stabilized by _
Placing chocks & wedges, then securing to a substantial object w/Utility Rope. Entry shall be via front/rear window
Removing a door: Which side may be more successful on newer car construction
Hinge side (but both hinge & nader pin side must be mastered)
A vehicle found on its side shall be secured to a substantial object using _
Utility rope (no member shall enter until properly stabilized)
When using the cutters on the hinge side first, which hinge do you cut first
Cut top and bottom hinges using cutters in that order. When a hinge has a spring, it must be removed prior to cutting the hinge.
Using the Vertical Push to establish a purchase point may force the door from Nader pin/staple. This method works best on _
Older vehicles. Newer vehicles have LW construction that could split the door.
If total roof removal need on a vehicle, how are the cuts made
Cut low on Post A and high on B, C, & D posts with cutters. Cut all posts on one side before passing tools to cut posts on opposite side.
3 tools to open a windshield
Sawzall with wood cutting blade, Windshield hand saw, or axe (last resort).
CR: Airbags
Two predominate types of glass for vehicle windows
Laminated safety glass for windshields, and tempered glass on sides & rear of window (tempered glass is being replaced by laminated glass or rigid plastics due to it being highly resistant to breaking)
Before any glass removal procedures are started, victims &/or rescuers should be protected from airborne glass debris. What shall be used
Salvage plastic or yellow exposure blankets are a good choice of protection. Fabric blankets are NOT good because they keep pieces of glass in the fabric & once contaminated must be placed OOS
Which tool shall be considered as a last resort for removing windshields
Axe using firm but NOT full strokes striking w/corner of axe blade
A vehicle on its side may need to have its roof removed after its secured to a substantial object. The tool of choice to do this would be
Air Chisel
Operators and members working in close proximity to operators must wear eye protection when tools are in use. This includes
Eye protection shields, Safety glasses, & Helmet mounted eye shields
Whether using spreaders or cutters always remove _
Top hinge first
If a members gets hydraulic fluid in their eyes, the member should flush their eyes w/clean water for at least _
At least 20 minutes & immediately seek medical attention
Who shall ensure the disconnection of the car battery
Ladder Officer. When disconnecting remove negative terminal first
What shall inside team ensure on vehicle
The car is in park, windows open, seats moved back and seatbelts removed before shutting down ignition
List the stabilization process of vehicles
Place step chocks, Shut down engine, Engage parking brake, Put transmission into park, and Disconnect battery
What must 1st arriving Officer do if they encounter a pinned victim
Immediately notify Dispatcher
Vehicle on its roof- Attacking the _ side would be the preferred method
Hinge side to remove the door
Incorrect car laying on its side
A. Good initial entry point into these vehicles is a side window
B. Step chocks & wedges should be placed under the side of the vehicle & tires
C. Vehicle should be secured to a substantial object (rig, tree, etc) w/a utility rope
D. No FF shall enter vehicle until it’s properly stabilized
A Front & rear windows
When would the Third Door Removal procedure be best suited as an extrication option
A. Victim is pinned in back seat of a 2 door car
B. Victims pinned in front seat of SUV
C. Victim pinned in back seat of 4 door vehicle
D. None of the above
A
Dashboard displacement: Make 2 cuts in bottom portion of A Post. Lower cut is made below hinge, parallel to rocker panel. Second cut is made _
Approximately 6-8 inches above the 1st cut. A metal hook is positioned between the cutters & rocker panel to prevent tool from moving in towards passenger compartment

A: Airbag systems are equipped with an energy storage feature that enables them to deploy even when the battery has been destroyed in an accident.
B: Airbags can be deployed either electronically or mechanically.

A. Engine should be divided into 2 teams, one for patient care duties & one to stretch & charge a HL
