Type of Extinguisher Effectiveness on Lithium-ion Fires

• Water ⚠️ Not effective
• Foam ⚠️ Risky; can spread fire
• DCP (Dry Chemical Powder) ✅ Better, but not always reliable
• Specialized Lithium Iron Extinguishers ✅ Most effective!

Class D extinguishers are designed specifically for flammable metals, making them effective against lithium battery fires. Other types, like CO2 and foam extinguishers, can be used in some cases but may not always be effective. Always check labels for proper use.

• Class D extinguishers: Best for lithium fires.
• CO2 extinguishers: Good for electrical fires, but not always effective on lithium.
• Foam extinguishers: Work for some flammable materials, but avoid lithium.
