How to put out a lithium battery fire
Lithium-ion batteries can catch fire if they are damaged, short-circuited, or overcharged. If you find yourself in a situation where a lithium-ion battery is on fire, it is important to take quick and appropriate action to put out the fire and prevent injury or damage. Here is a step-by-step guide on how to put out a lithium-ion battery fire:
Stay safe: If the battery is on fire, it is important to prioritize your own safety. Stay away from the fire and make sure that you are not at risk of being burned. If you are unable to safely reach the battery, evacuate the area and call 911 or your local emergency services for help.
Cut off the power supply: If the battery is still connected to a charger or device, disconnect it immediately. Unplug the charger or turn off the device to cut off the power supply to the battery.
Use a fire extinguisher: If you have a fire extinguisher readily available, use it to put out the fire. Aim the nozzle of the extinguisher at the base of the fire, and use a sweeping motion to cover the entire area. Be sure to use the correct type of fire extinguisher for the materials involved in the fire. For a lithium-ion battery fire, use a Class D fire extinguisher, which is specifically designed for fires involving combustible metals.
Use baking soda: If you do not have a fire extinguisher, you can use baking soda to put out the fire. Baking soda is a good choice because it is a mild alkali that can neutralize the acid in the battery, which can help to extinguish the fire. Simply sprinkle a generous amount of baking soda over the battery to extinguish the fire.
Use a fire blanket: If the battery is small and portable, you can use a fire blanket to smother the fire. A fire blanket is a large piece of fire-resistant material that can be used to cover the battery and cut off the oxygen supply to the fire. This can help to extinguish the fire.
Do not use water: Do not try to put out a lithium-ion battery fire with water. Water can actually make the fire worse, as it can cause the battery to short-circuit and create even more heat and flames. Water should only be used as a last resort if you do not have access to any other means of extinguishing the fire.
Dispose of the battery safely: Once the fire has been extinguished, it is important to dispose of the battery safely. Do not touch the battery with your bare hands, as it may still be hot and could cause burns. Instead, use tongs or gloves to carefully place the battery in a metal container, such as a coffee can, and cover it with a lid. If the battery is still hot, allow it to cool down before sealing the container. Dispose of the container in a designated hazardous waste facility.
By following these steps, you can effectively put out a lithium-ion battery fire and prevent further injury or damage. It is always a good idea to have a fire extinguisher on hand in case of emergencies, and to be familiar with how to use it.
