- Sweep the extinguisher from side to side, covering the entire fire area until the flames are completely smothered.
- Continue monitoring the area for any re-ignition and repeat the process if necessary.
2. Class D Fire Extinguisher
Class D fire extinguishers are specifically designed to combat fires involving reactive metals such as lithium. These extinguishers contain dry powder materials that can rapidly cool down and suffocate the fire. It is important to note that not all fire extinguishers are suitable for lithium battery fires. Therefore, it is crucial to ensure you have a Class D fire extinguisher available. Follow these steps when using a Class D fire extinguisher:
- Locate the Class D fire extinguisher and carefully read the instructions on its proper usage.
- Aim the nozzle at the base of the fire, maintaining a safe distance of approximately 8 to 10 feet.
- Depress the handle or lever to discharge the extinguishing agent.
- Sweep the extinguisher from side to side, covering the entire fire area until sufficient cooling and suffocation have been achieved.
3. Sand or Dry Soil
Using sand or dry soil is an effective method to smother a small lithium battery fire. These materials act as heat insulators and prevent the fire from spreading or reigniting. Follow these steps when using sand or dry soil:
- Ensure you have access to a sufficient quantity of sand or dry soil.
- Use a shovel or any suitable tool to cover the entire fire area with sand or dry soil.
- Allow the sand or dry soil to completely cover the flames and smother the fire.
- Ensure the fire is fully extinguished by monitoring the area for any signs of re-ignition.
4. Covering with a Fire Blanket
If the lithium battery fire is small and contained, using a fire blanket can be an effective method to suppress the flames and restrict the fire’s oxygen supply. Follow these steps when using a fire blanket:
- Locate a fire blanket and ensure it is large enough to cover the entire fire area.
- Approach the fire cautiously and position yourself upwind to avoid inhaling toxic gases.
- Using protective gloves, carefully unfold the fire blanket.
