  1. MVA Safety and Principles of Extrication McLANE/BLACK LAKE FIRE DEPT Presented by: Captain Casey Sobol

  2. DRILL OUTLINE • Preparation • Response • Assessment • Hazard Control • Support Operations • Gaining Access • Emergency Care

  3. Disentanglement • Remove and Transfer • Termination 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.

  4. PREPARATION • Proper Training • Proper Equipment for the conditions and situation

  5. RESPONSE TO THE SCENE • Follow all Dept. response policies • Remember, 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.

  6. SCENE ASSESSMENT AND HIGHWAY SAFETY

  7. 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

  8. DON’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 traffic • Always remain in radio contact with person doing traffic control • Always leave yourself a way out.

  9. Scene Hazards • A 360 must be completed prior to any other activities being performed. • Downed Power Lines • Unstable Structures and vehicles • Hazardous Materials • Other?

  10. OTHER 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

  11. Supplemental Restraint Systems • 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”.

  12. 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

  13. 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.

  14. Hybrid Vehicles • Avoid 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.

  15. 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.

  16. SUPPORT OPERATIONS • Lighting • Scene • Extrication Area • Patient Assessment • Helicopter LZ – Review LZ set-up and video (optional)

  17. GAINING ACCESS • Hand Tools – Types of hand tools • Power Tools - Types of Power tools • Normal Means – Unlocked or open doors and windows, “Try before you pry” • Alternate Means – Front and rear windows, locked doors and windows

  18. EMERGENCY CARE • Patient Assessment – 90 second survey. Determine ALS vs. BLS and Rapid extrication vs. routine. • Upgrade early, upgrade fast. • MOI?? • Coordination with extrication personnel • Patient Immobilization

  19. DISENTANGLEMENT • Coordinate with EMS personnel regarding route of removal. • STOP, LOOK, THINK, PLAN OF ACTION, ACT

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

  21. Remember, when performing extrication operations on a vehicle, for every action, there is a Reaction.

  22. REMOVAL & TRANSFER • Assisting with Victim Removal • Coordinated • Be Prepared • Good Communications • Transfer of pt. Care • Proper documentation and pictures (if possible)

  23. TERMINATION OF INCIDENT • Scene Clean-up • Inventory equipment • Check equipment function • Place apparatus back in service • Decon all equipment as necessary per department SOP’s
