How to deal with lithium ion battery fire

When a fire occurs in a lithium-ion battery, use a water fire extinguishing bottle or other non-flammable liquid to cool the battery core and the device to cool the battery core in the fired battery and prevent the heat from continuing to spread to the adjacent battery core. If there is no water fire extinguisher, other non-flammable liquids can be used to cool the battery cells and devices. If there is an open flame, use the Helen fire extinguishing bottle to control the fire spreading to the surrounding due to the fire of the lithium ion battery. After using Helen or water fire extinguisher to extinguish the fire, immediately use water or water-containing non-flammable liquid to fully cover and soak the lithium-ion battery, because only water or water-containing non-flammable liquid can sufficiently cool the lithium-ion battery or lithium-ion battery pack The battery cell and prevent re-ignition. 2. Lithium ion battery fire disposal procedures ① Disconnect or remove the external power supply on the fire equipment (if applicable); ② Use Hailun fire extinguisher or water fire extinguisher to extinguish the fire; ③ Immediately and continuously soak the electronic equipment in the fire with water or other non-flammable liquids, reduce The temperature of the battery cell of the lithium-ion battery unit blocks heat dissipation and prevents adjacent battery cells from catching fire; ④If the device was previously connected to the power socket, unplug the power from all other power sockets until the system is confirmed to be faultless; ⑤Extinguish the fire; During this period, keep in touch with the control room without interruption. 3. Precautions for fire disposal of lithium-ion batteries ①When using water or non-flammable liquids to soak electronic equipment containing lithium-ion batteries, prevent the water from splashing on other electronic equipment in the aircraft system; ②Do not attempt to move, burn or emit smoke To prevent serious personal injury; ③Do not use objects to cover the electronic equipment or try to use ice cubes to reduce the temperature. This method of isolating the equipment will cause the equipment to overheat faster. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
