EMS 3.2.1

Primary Objectives of a Secondary Inspection: Detect Residual Energy in Battery Modules and Cells NEXT • Even after an EV fire is extinguished or the vehicle is initially stabilized, residual energy
can remain in undamaged battery modules and cells. This stranded energy poses a risk
of re-ignition, particularly during the critical first 24–48 hours of storage. Primary Objectives of a Secondary Inspection: Confirm the Shutdown of the High-Voltage System • Secondary inspections ensure the high-voltage system has been properly shut down,
isolating it from the rest of the vehicle and rendering it safe to handle. NEXT • A damaged high-voltage system can remain active even after an incident, creating
risks of electrocution or further battery instability. Primary Objectives of a Secondary Inspection: Identify Hidden Damage to the Battery • Detecting these issues early is critical to preventing secondary hazards, such as battery
leakage or thermal runaway, and helps inform decisions about repair, storage, or disposal. • Secondary inspections allow for a thorough evaluation of the battery pack and surrounding
components to uncover hidden damage. NEXT Primary Objectives of a Secondary Inspection: Ensure the Vehicle is Safe to Handle, Process, or Move • For high-risk vehicles, additional precautions such as isolation, continued monitoring,
or containment measures may still be required before declaring the vehicle safe for
inventory or processing. • Secondary inspections verify that all safety protocols have been followed and that
the vehicle is stable enough for further handling. NEXT Primary Objectives of a Secondary Inspection: Minimize Risks to Personnel and Facilities • A robust secondary inspection process also demonstrates a facility’s commitment to industry
best practices and compliance with evolving safety standards. • Secondary inspections play a vital role in ensuring the safety of everyone involved in handling
damaged EVs, including tow operators, facility personnel, and emergency responders.
