Training Objective:

The student will demonstrate a basic understanding of passenger vehicle extrication and the associated tools and techniques through participation in class discussion and practical activities.

Proper TrainingProper Equipment for the conditions and

situation

RESPONSE TO THE SCENERESPONSE TO THE SCENE

Follow all Dept. response policiesRemember, this is NOT your emergency.

You have been called to assist someone else.

If we can’t arrive safely, we are no help.Be preparing mentally enroute to the call.

SCENE ASSESSMENT SCENE ASSESSMENT AND HIGHWAY AND HIGHWAY

SAFETYSAFETY

Warning on-coming traffic– Set-up appropriate warning devices such as

flares, strobes, traffic cones well ahead of accident scene

At least 400’ before the accident Don’t use flares in cold, foggy conditions!!

– Request additional units if necessary

Protecting the Scene– Park apparatus in a “defensive position”– Your engine is the best road block

DON’T BECOME A VICTIMDON’T BECOME A VICTIM

Dozens of Firefighters and EMT’s die every year across the U.S.A. while operating at MVA’s.

Never turn your back to on-coming trafficAlways remain in radio contact with person

doing traffic controlAlways leave yourself a way out.

OTHER ASSESSMENTOTHER ASSESSMENT

Victims outside vehicles (ejection) Hot and Cold zones around accident Size-up before beginning activity “READ THE WRECK” Additional Resources? Full protective equipment a must!! Set-up Tool Staging Area (Engine Operator or per

dept. SOP’s) Supplemental Safety Systems

Supplemental Restraint Supplemental Restraint SystemsSystems

Air Bags – Deployed or not? Location?– Front Impact Bags – Do Not put yourself between

undeployed bag and patient.– Side Impact Bags – Normally curtain type from ceiling

or side of seat mounted. Cylinder for systems normally in A, B, or C post. Avoid!! Pull off trim to expose and identify location before cutting.

– Rear seat bags – Newer high end cars.– NO universal marking system. Most, however use

SRS, HPS, IC, SIPS, or “Airbag”.

Static Electricity can cause air bags to deploy.

Remember the 5-10-20 Rule:– 5” away from side air bags– 10” away from steering wheel air bags– 20” away from front passenger air bags

Air Bag Deactivation Times – Cutting the battery cables doesn’t always work! The system can still hold a charge! Vary depending upon make, model of vehicle. Some older vehicles can hold a charge for up to 20-30 minutes.

Battery locations – Vary based upon make, model. Batteries can now be found under hood, in the trunk, in the wheel well, and behind the rear seat.

Hybrid VehiclesHybrid VehiclesAvoid ORANGE wires – They are part of

the high voltage system!Turn off ignition and remove key to render

car safe.Remember, the SILENT CAR. It may be

running and can move even if you don’t hear it!

High voltage systems are very safe.

Seat Belt Pre Tensioning

Seat Belt Pre-Tensioner systems – Designed to pull back seatbelt upon impact in coordination with airbag system. A part of the total SRS system.

Normally found mid-height or near the floor in the door post. Contains an explosive charge similar to shotgun shell. Avoid cutting into this as it may go off.

Hand Tools – Types of hand toolsPower Tools - Types of Power toolsNormal Means – Unlocked or open doors

and windows, “Try before you pry”Alternate Means – Front and rear windows,

locked doors and windows

EMERGENCY CAREEMERGENCY CARE

Patient Assessment – 90 second survey. Determine ALS vs. BLS and Rapid extrication vs. routine. – Upgrade early, upgrade fast.– MOI??

Coordination with extrication personnelPatient Immobilization

DISENTANGLEMENTDISENTANGLEMENT

Coordinate with EMS personnel regarding route of removal.

STOP, LOOK, THINK, PLAN OF ACTION, ACT

Disentanglement techniques– Door Removal– Roof opening and removal– Seat Displacement– Steering Wheel Cutting– Steering Wheel Displacement– Pedal Displacement– Dash Roll-up

Remember, Remember, when performing when performing

extrication operations on a extrication operations on a vehicle, vehicle, for every action, for every action,

there is a Reaction.there is a Reaction.

REMOVAL & TRANSFERREMOVAL & TRANSFER

Assisting with Victim Removal– Coordinated– Be Prepared– Good Communications– Transfer of pt. Care– Proper documentation and pictures (if possible)

TERMINATION OF TERMINATION OF INCIDENTINCIDENT

Scene Clean-up– Inventory equipment– Check equipment function– Place apparatus back in service– Decon all equipment as necessary per

department SOP’s
