Hazards Chart

Below is a chart of potential hazards and mitigation controls for EV recovery:

Hazard Type Specific Hazard Mitigation Controls
Chemical Battery Leakage • Wear appropriate PPE for electrolyte exposure.
• Neutralize spills with dilute boric acid or vinegar.
• Wash affected areas with water. • Seek medical attention if exposed.
Toxic Gas Emission • Use full PPE, including respirators.
• Ensure proper ventilation.
• Avoid inhaling released gases.
Battery Fire • Apply up to 10,000 liters of water for cooling.
• Control battery temperature for at least 1-hour post-cooling.
• If extinguishing isn’t feasible, let the fire burn out in a controlled manner to minimize toxic runoff.
Electrical Electric Shock • Isolate the vehicle's high-voltage systems.
• Wear insulated gloves.
• Avoid direct contact with HV components.
• Disconnect the 12V battery if safe to do so.
Arc Flash • Wear natural fiber, full-length clothing.
• Remove all metal objects (rings, watches, etc.).
• Use face protection and insulated gloves to prevent burns.
Thermal Thermal Runaway • Apply copious amounts of water directly to the battery.
• Avoid re-engagement until cooling is confirmed.
• Maintain at least a 50-foot clearance from the vehicle if thermal runaway is likely.
High-Voltage Battery Fire • Contact emergency services immediately (911).
• Use Class D fire extinguishers for lithium-metal fires.
• Utilize full PPE and ensure a controlled containment area.
Environmental Toxic Runoff and Contamination • Conduct an environmental assessment.
• Use containment methods to manage toxic runoff.
• Create a safe perimeter to protect nearby water sources and vegetation.
