⚠️ The Hidden Risk in EV Fires: Hydrogen Build-Up
Most people focus on the flames.
But during an EV battery fire, thermal runaway can generate a range of flammable gases, including hydrogen.
A fire blanket may help contain flames, smoke and radiant heat, but responders must also consider what is happening underneath the blanket.
As damaged battery cells continue to decompose, gases can continue to be released. In confined or poorly ventilated conditions, these gases may accumulate beneath the blanket.
This creates an important challenge:
🔥 The visible flames may be suppressed
⚠️ Flammable gases may still be present
⚠️ Thermal runaway may still be occurring inside the battery pack
⚠️ Re-ignition can occur when oxygen is reintroduced
The objective should not only be to hide or contain the fire.
The objective is to:
✅ Stop thermal runaway
✅ Cool the battery cells
✅ Reduce gas generation
✅ Prevent re-ignition
As EV adoption accelerates worldwide, understanding the chemistry behind lithium battery fires is becoming just as important as controlling the flames themselves.
An EV fire is not simply a fire problem. It is a thermal and chemical event. The only Solution is FIRE TERMINATOR.
