Study Notes

Emergency Response Procedures for Vehicle Accidents

  • Initial Response: Company Officer may request additional units based on observed conditions, area knowledge, number of vehicles/patients, or unusual circumstances. Refer to SOG 100-01 for details.

Arrival Report & Resources

  • Upon arrival, request additional resources like engines, rescue units, EMS Captain, Battalion Chief, Aerials, Special Operations (extrication/hazmat), Law Enforcement (traffic control), Utilities, and Road Rangers (turnpike). Refer to SOG 210-01.
  • If hazardous materials are present, follow SOG 700-02.

Incident Management

  • Follow SOG 200-02 for Incident Command Sequence.

Apparatus Placement

  • Use SOG 310-01 for traffic operations; consider safety hazards like fuel leaks (park uphill/upwind), hazardous materials, power lines, and damage to poles.

Communications

  • Incident Commander broadcasts incident benchmarks per SOG 210-01.

Scene Stabilization

  • Reference SOG 310-01 for further safety considerations.
  • Ensure proper PPE for personnel.
  • No unauthorized personnel in Hot Zones without proper PPE.
  • Isolate live electrical wires; establish an Exclusion Zone.

Vehicle Stabilization

  • Stabilize damaged vehicles to prevent further movement. This includes parking brakes, turning engines off, and wheel chocks.
  • Crib and chock vehicles on their side, on barriers, or upside down using appropriate stabilization techniques (step chocks, 2x4s, 4x4s, etc.).
  • Special Operations/Aerials utilize specialized stabilization gear, including Kodiak & Capabear Claw kits, lift bags, and chains/webbing.
  • Consider all airbags as "loaded"; remove interior plastic and visually scan for airbags or curtains to ensure no unintended deployment.
  • Maintain a safe distance between personnel and airbags.
  • Elevating tilt steering and moving front seats protects against airbag deployment trauma.
  • In cases of significant damage or extrication:
    • Cut the negative, then the positive battery cables. Remove a ½ inch of cable and cover cable ends with electrical or duct tape.
    • If cutting and removing a section of cable is not possible, remove the cables from the battery posts and place them so they cannot connect back to the battery or come in contact with any metal objects. This minimizes hazards, but does not eliminate them.
  • Maintain a safe distance between the patient and airbag. When possible, hold cervical spine immobilization of front seat occupants from the rear seat. If possible, move the front seat back and away from the front dash or front steering wheel airbag to minimize trauma should the airbag deploy.

Patient Extrication

  • Vehicles should electrically isolate to minimize potential harm by cutting negative then positive battery cables. Cover exposed ends with tape or remove completely if cutting/removing isn't possible.
  • Be cautious in cutting or activating devices from:
    • Loaded side impact airbags (inside doors and seats)
    • Seatbelt pre-tensioning devices (“B” post)
    • Rollover bags (A, B, C posts/roofline)
    • Knee Airbags (front dash)
    • Inflatable seatbelts
  • Deploy a 1 ¾" hose line for protection against hazards, if necessary.
  • Assign personnel in PPE to hose line if potential fire exists. If fuel issues exist prioritize foam application.

Fuel Types

  • Gasoline, Diesel, Gasoline-electric hybrids, Plug-in hybrids, Battery electric, Biodiesel, Ethanol/flex fuel, Propane/LPG, Natural Gas/CNG, Fuel Cells.
  • Different fuels have unique hazards. Fuel Cells (often hydrogen) show no flame or smoke, only heat signatures; safety precautions are needed.
  • Lack of standardization on fuel type marking/labeling.

Emergency Scene Activities

  • First Arriving Unit: Establish Incident Command, stabilize scene/vehicles, provide patient care, and extricate victims. Remove vehicles for minor damage and injuries, using orange spray paint to mark wheel placement. Notify Law Enforcement if leaving the scene.
  • First Arriving EMS Captain: Complete a 360-degree size up and become the Incident Safety Officer. May establish a Medical Group for multiple victims.
  • First Arriving Chief Officer: Assume Incident Command if incident is escalating or unstable. Otherwise, serve in an advisory capacity with the Incident Commander, if not escalating. For extrication requiring powered tools: request Aerial and Special Operations. Assign an extrication group.

Powered Tool Extrication

  • If powered hydraulic, electric, or battery tools are needed to extrication a victim, the Incident Commander should request the closest Aerial, Special Operations, and assign an Extrication Group or Division.
