Electric Vehicle Fire Erupts at Colorado Charging Station, Firefighters Let it Burn

EV Fire Incident in Littleton, Colorado

• ⚡ A Nissan Leaf electric vehicle caught fire while charging at a King Soopers in Littleton, Colorado.
• ⚠️ The vehicle was unplugged by its owner after smoke was noticed, but the smoke continued to progress.
• 🚒 Firefighters responded and found the vehicle in thermal runaway, a state where the battery cells burn sequentially.

Firefighting Response and Protocols

• 🚫 Firefighters' current response guideline for EV fires is to let the lithium battery blaze burn itself out.
• 💧 Water is not used initially to avoid mixing with combustion products, which creates a greater environmental impact than letting the smoke rise.
• 💨 The strategy aims to minimize environmental hazards by allowing smoke to dissipate into the atmosphere, following EPA recommendations.
• 🛡️ Fire crews focused on protecting exposures, such as nearby trees and charging stations, and isolating the area from the public.

Thermal Runaway Explained

• 💥 Thermal runaway occurs when damaged or heated lithium-ion batteries in an EV create a chain reaction, with one battery heating up the next.
• 📈 The fire progressed from smoking to a pressurized flame from the bottom, indicating batteries were actively burning.
• 🧊 After the battery compartment burning phase, crews attempted extinguishment with water and foam, which suppresses vapors and minimizes water runoff.

Post-Fire Procedures and Safety Advice

• 🧽 Firefighter gear exposed to EV fire toxins undergoes specialty cleaning using carbon dioxide and testing for hazardous substances like HF.
• ⚠️ EV owners are advised to follow manufacturer recall information, use reputable charging stations, and get any vehicle damage checked immediately.
• 🚨 If smoke is noticed during charging, owners should unplug the vehicle, back away, and call 911.
• 🚚 EVs involved in fires are transported to specially designated tow yards to prevent further thermal runaway incidents.
