EMS 2.2.2

Review: Key Takeaways from the Incident

(This was covered in the video)

  • Fire Suppression and Battery Separation
    • Firefighters applied 200-300 gallons of water to extinguish the flames and cool multiple battery sections.
    • The battery’s separation from the vehicle added complexity to the suppression efforts.
  • Reignition Challenges
    • The battery reignited twice during loading, once while being winched and again when a chain made contact.
    • Minimal water was required as the battery self-extinguished shortly after each reignition.
  • Tow Yard Safety Measures
    • The vehicle and battery were stored at least 50 feet away from other vehicles and structures.
    • Damaged components were secured using clear plastic and tarps.
  • Post-Crash Analysis Findings
    • Extensive thermal damage to the battery, including ruptured and dislodged modules, contributed to reignition risks.
    • Mislabeling of the cut-loop location complicated responders’ ability to safely deactivate the high-voltage system.
