リチウム電池の火災の消火方法

If you ever find yourself with a lithium battery fire, don’t panic! There are several ways to put out the fire and prevent it from spreading.

While most batteries can be safely extinguished with water, lithium-metal batteries must be cautiously treated. Since water can make them spread, these fires are infamously challenging to put out. The most effective way to put out a lithium-metal fire is with a Class D fire extinguisher. These extinguishers function by smothering the fire with a fine powder and were created especially for use on combustible metals. If you don’t have a Class D extinguisher on hand, you can also use dry sand or dirt. Cover the burning battery with a thick layer of sand or mud and wait for the fire to go out. Never try to put out a リチウム-metal fire with water; doing so could result in serious injury.

Can You Put Out a Lithium Battery Fire With Sand?

Lithium batteries are powering an ever-growing number of devices, from cell phones to electric cars. While lithium batteries are very safe, they can catch fire if they are damaged or defective. If a lithium battery fire does occur, it is essential to know how to extinguish it. Dry sand or table salt can be used to smother the fire and prevent it from spreading. However, water should not be used, as it can cause the battery to explode. Once the fire has been extinguished, the battery should be removed from the device and disposed of properly. 

What Can I Do With a Hot Lithium Battery?

When lithium batteries overheat, it can be a hazardous situation. The battery should be taken out of the device it is in as soon as possible. If the battery is in a sealed container, such as a 電話 or laptop, then carefully remove the battery and put it in a fireproof container. If the battery is not in a sealed container, then put it outside, away from flammable materials. Once the battery is removed from the device or placed in a fireproof container, wait for the symptoms to dissipate. Symptoms of a lithium battery overheating include: swelling, leaking, emitting smoke or fumes, and catching fire. If any of these symptoms persist, then contact a professional for help.

How Common Are Lithium Battery Fires?

Despite their widespread use, fires caused by lithium batteries are quite rare. Only 1 in 10 million lithium battery fires occur each year, according to the National Fire Protection Association. Lithium batteries are made with safety in mind contributes to this low rate. For example, most lithium batteries are equipped with thermal fuses that cut off power if the battery overheats. In addition, many devices that use lithium batteries, such as laptops and cell phones, are designed with fire-resistant materials. As a result, while lithium battery fires occasionally happen, they are far less common than other types.

Are Lithium Battery Fires Toxic?

Li-ion batteries can release several toxic substances when they heat up or catch fire. These substances include carbon monoxide (CO), carbon dioxide (CO2), and other toxins. While the exact effects of these substances will depend on the individual, they can potentially cause various health problems, including asphyxiation, anoxia, and poisonings. In some cases, these fires can also release large amounts of smoke, which can be difficult to breathe and cause respiratory problems. Because of this, it’s critical to be informed of the potential risks associated with lithium battery fires and to take steps to avoid them.

What Causes a Lithium Battery to Catch Fire?

Lithium batteries are incredibly powerful, and as a result, they are often used in electronic devices like phones and laptops. However, lithium batteries can also be dangerous, as they are prone to catching fire. It typically happens when the battery experiences what is known as thermal runaway. Thermal runaway occurs when the battery’s temperature gets too high, causing a chain reaction that generates more heat. It can cause the battery to burst into flames, which can be difficult to extinguish. The fire can sometimes spread to other parts of the device or nearby objects. As a result, it is important to be aware of the risks associated with lithium batteries and to take steps to prevent them from overheating.

What Happens When You Mix Lithium With Water?

Lithium is a highly reactive element. It releases hydrogen gas and lithium hydroxide when it interacts with water. The reaction is extremely exothermic, releasing a large amount of heat. Because of the intense heat released, hydrogen gas can easily catch fire, making this a dangerous reaction. In addition to the fire risk, the lithium hydroxide produced by the reaction is also highly corrosive. The skin and eyes may suffer severe harm as a result of it, so it is essential to be very careful when handling lithium.

What Happens When Lithium Batteries Burn?

A lithium battery will become unbearably hot or swell up when it starts to overheat (the device may look like it has a lump or bulge). Then it could start to deteriorate, blister, and smoke while also causing damage. In severe cases, the battery can catch fire and cause extensive damage. Following the manufacturer’s instructions for charging and using lithium-ion batteries is essential. If you suspect a battery is starting to fail, it is ベスト to take the device to a professional for an inspection.

Does Lithium Explode in the Air?

Lithium is an element that is highly reactive and flammable. When lithium is exposed to the oxygen in the air, it can ignite or even explode. It is because oxygen causes a chemical reaction with lithium, which produces heat and energy. The heat and energy can cause the lithium to catch fire or explode. This is why it is important to handle lithium carefully and keep it away from open flames. There have been cases where people have been injured or killed by lithium explosions, so it is not something to take lightly.

Lithium battery fires are a serious concern, but they can be put out with the right knowledge. Knowing how to deal with a lithium battery fire properly can help keep you and your loved ones safe. If you ever encounter a lithium battery fire, remember these key points and stay calm. You can handle it!
