How to Extinguish a Lithium Battery Fire Safely and Effectively
Learn how to extinguish a lithium battery fire safely using ABC extinguishers, foam, or Class D agents. Follow key steps to prevent reignition and ensure safety.
The batteries contain liquid electrolytes that provide a conductive pathway, hence the Class B classification. To extinguish a lithium-ion battery fire, use a standard ABC or dry chemical fire extinguisher. Clean agent fire suppression systems are particularly well-suited for addressing lithium-ion battery fires.
Yes. If a lithium battery fire cannot be avoided, several techniques should be used to put it out quickly and safely. The most effective way to extinguish a lithium battery fire is usually with either water or dry chemical powder-based extinguishers such as Class D extinguishers.
For lithium battery fires, a standard ABC or CO2 extinguisher is not recommended. Instead, use an extinguisher specifically designed for these fires. An encapsulator agent extinguisher like F-500 EA or a certified lithium-ion fire model is best.
Foam extinguishers can sometimes help control smaller lithium battery fires, although they are not ideal. Apply the foam at the base of the fire and move closer only if it is safe to do so. Keep in mind that foam may suppress the fire temporarily, but it might not fully cool the battery, leaving a risk of reignition.
