Safely Managing Lithium-Ion Battery Fires: A Step-by-Step Guide

Lithium-ion (Li-ion) batteries are a common source of power for many of our devices due to their high energy density. However, they can pose significant fire risks if not handled properly. Li-ion fires are classified as Class B fire hazards, and they can escalate rapidly, releasing toxic gases that endanger human health. This article provides a comprehensive guide to safely extinguishing Li-ion battery fires.

Safely Managing Lithium-Ion Battery Fires: A Step-by-Step Guide

Recognizing the Severity of Li-Ion Battery Fires

Li-ion batteries belong to Class B fire hazards, indicating that they involve flammable liquids or gases. When a Li-ion battery ignites, it can swiftly transform into a ferocious blaze, posing a grave threat to individuals in the vicinity. The gases emitted during such fires are toxic and can be harmful when inhaled.

Essential Steps to Take During a Battery Fire

  1. Unplug the Device: Your immediate action should be to unplug the device from its power source. This step is crucial for disconnecting the flow of electrical current to the battery.
  2. Contact the Fire Department: Dial your local fire department’s emergency number without delay to report the Li-ion battery fire. Firefighters are specially trained to tackle these situations and can provide the necessary assistance.
  3. Using a Fire Extinguisher: If available, retrieve an ABC- or BC-rated fire extinguisher and aim it at the base of the fire. These types of fire extinguishers are specifically designed to suppress flammable liquid and gas fires.
  4. Alternative Extinguishing Materials: In the absence of a fire extinguisher, you can use alternative materials such as sand, clay cat litter, baking soda, or, as a last resort, water to try to suppress the fire. However, it’s important to exercise caution with water, as it can exacerbate the situation or create electrical hazards if it comes into contact with live electricity.

Prioritizing Safety During Li-Ion Battery Fires

  • Protect Yourself: Prioritize your safety by wearing protective clothing, gloves, and goggles to shield yourself from the fire and potential hazards.
  • Evacuation When Necessary: If the fire becomes uncontrollable, air quality deteriorates due to toxic gases, or the fire rapidly spreads, your first priority should be to evacuate the area. Material possessions can be replaced, but human lives are irreplaceable.


Effectively managing a lithium-ion battery fire requires quick and cautious action. By adhering to the steps outlined in this guide and making safety a priority, you can minimize the potential risks associated with Li-ion fires. It is crucial to handle and store Li-ion batteries properly to prevent accidents and ensure the safety of yourself and those around you.
