Lithium ion battery, as a kind of battery with high energy density, is widely used in electronic equipment, electric vehicles and other fields. However, due to its special chemical properties, once a fire accident occurs, it may cause serious consequences. This article will focus on discussing the the harm of fire lithium ion batteries and the initial disposal countermeasures, so as to improve people's understanding and coping ability to fire risks.

1. Lithium ion battery the harm of fire

lithium ion battery fire may cause the following hazards:

• high-temperature combustion: after the lithium ion battery is on fire, a high-temperature flame will be generated, and the combustion temperature is high, which is easy to cause the combustion of surrounding objects;
• toxic gas release: the smoke released by the lithium ion battery fire contains toxic gas, causing harm to human health;
• explosion risk: in the process of fire, lithium ion batteries may have short circuit, overheating, etc., and there is an explosion risk.

2. Initial disposal countermeasures of lithium ion battery fire

for lithium ion battery fire, the following initial disposal measures should be taken:

• evacuation personnel: when a fire is found, inform the surrounding personnel to evacuate to a safe place immediately to ensure the safety of personnel;
• use Fire Extinguisher: if conditions permit, you can use dry powder fire extinguisher and other applicable fire suppression for fire extinguishing;
• avoid direct contact: try to avoid direct contact with the fire site to avoid being hurt by high temperature and toxic gases;
• keep away from fire Source: keep other combustible goods away from fire source to reduce the possibility of fire spread;
• contact fire protection: call the fire alarm number in time to inform the fire brigade to put out the fire.

3. Subsequent treatment of lithium ion battery fire

in case of lithium ion battery fire, follow-up treatment is required:

• isolation fire area: isolate the fire site to prevent others from approaching and ensure safety;
• eliminate risks: check the surrounding environment to eliminate the risk of fire spread and recurrence;
• disposal residues: professional disposal of lithium ion batteries and other items left in the fire to avoid secondary safety accidents.

4. Preventive measures

• strictly abide by the instructions: when using electronic equipment, strictly abide by the requirements of use and charging in the instructions;
• avoid excessive charge and discharge: avoid excessive charge and discharge of lithium ion batteries and prevent battery damage;
• regularly check the battery status: regularly check the appearance and performance of the battery, find problems in time and deal with them;
• avoid high temperature environment: avoid exposing electronic equipment to high temperature environment for a long time, and prevent the battery from overheating and causing fire.

Lithium ion battery fire has serious harm, which needs people's attention. By strengthening the understanding of lithium ion battery fire, mastering the initial disposal countermeasures and improving the ability of self-rescue and escape, the loss of fire accidents can be effectively reduced.
