When storing an EV with a damaged battery, what minimum distance must separate it from other combustibles?

• A. 10 feet
• B. 50 feet
• C. 100 feet
• D. 5 feet

Answer: (B)

Keeping the damaged EV battery separated from combustibles by a substantial distance is a risk-reduction measure. A damaged lithium‑ion pack can experience thermal runaway, vent flammable electrolyte, and emit toxic gases. If heat, flame, or vapors reach nearby combustibles, a small incident can quickly escalate. Having at least 50 feet of separation minimizes the chance that heat or vapors will find a fuel source and gives emergency responders room to work and control a potential fire. The smaller distances wouldn’t provide enough buffer to reduce those risks, while a much larger distance is unnecessary for most storage scenarios.
