How to extinguish lithium-ion battery fire?

Extinguishing a lithium-ion battery fire requires caution, as these types of fires can be extremely dangerous and require specific handling. Here’s how to manage and extinguish a lithium-ion battery fire safely:

1. Use the Right Fire Extinguisher

• Class D Fire Extinguisher: If available, use a Class D fire extinguisher designed for metal fires, as lithium-ion batteries are often composed of metals like lithium.

• ABC or CO2 Fire Extinguisher: If a Class D extinguisher is unavailable, a Class ABC or CO2 fire extinguisher can also work, but these might not be as effective for fully containing a lithium-ion battery fire.

• DO NOT use water: Never use water to put out a lithium-ion battery fire. Water can react with lithium and cause an explosion or further intensify the fire.

2. Isolate the Battery (If Safe to Do So)

• Disconnect the battery (if possible): If the fire is small and you can do so safely, cut the power supply to the device, or isolate the battery to prevent the fire from spreading.

3. Wait for Professional Help

• Call emergency services immediately if the fire is beyond your control. Even after the fire seems to be out, lithium-ion batteries can reignite due to thermal runaway.

4. Avoid Breathing Smoke or Fumes

• Stay clear of smoke as lithium-ion battery fires can release toxic gases such as hydrogen fluoride, which can be harmful to health.

Important Reminders:

• Battery containment: If the battery is already venting smoke or flames, the fire can spread rapidly, so prompt action is critical.

• Do not touch the battery: Avoid direct contact with a burning lithium-ion battery, as it can cause burns or release hazardous chemicals.

It’s crucial to prioritize safety and call the fire department if you're unsure about how to manage the situation.
