How do you protect yourself if the lithium battery explodes?

Look at your home. Look at your office. How many electronic devices do you have? Notebooks, smartphones, tablets, chargers, chargers, and more? A lot, I bet.

Most of the time, electronic equipment works well. If something goes wrong, it can cause disaster within seconds.

Why do smartphones, laptops and other electronic devices explode? For example, Galaxy Note 7 and suspended skateboarding have exploded, so today we're going to find out why, and see what we can do to protect ourselves and our families.

According to British regulations, I conducted an electronic safety test and found that there are two major threats users need to face:

-Battery explosion.

-- Users touch high-voltage electricity(mostly through damaged equipment, wires, and sometimes because of poor design).

When it comes to smartphones, laptops, chargers, and similar devices, many of the problems come from chargers or batteries. Modern rechargeable batteries store a lot of electricity in a small space. Most of the time, the battery operates in the desired mode and slowly outputs electricity in a controlled manner. If a cause causes a rapid release of electricity, there is a risk of explosion or fire.

I 've seen the battery on fire a few times, some deliberately, some unexpectedly, and I'm impressed that we carry so much "electricity" in our pockets and backpacks.

Don't get me wrong, the defective lithium-ion battery is quite dangerous and it could explode. The so-called explosion is not a slight noise. It is like a party fireworks. It makes adults jump up and make children excited and scream. The battery explosion will make a relatively large, heavy sound, and the shell of the wrapping device will break, forming a glass shock wave.

Bang, glass splashes, we have other concerns, sometimes melted lithium metal splashes on the body, but also the release of pungent toxic gas.

If you are outdoors, well ventilated, away from combustible materials, it is unlikely that intense chemical reactions will occur. Unfortunately, explosions are often unexpected. We might put the device in our pockets or charge it in our car, drive on the highway, or put our cell phone next to our head in the middle of the night.

Thank God, explosions and fires don't happen all the time.

Why did the device explode and catch fire? The reasons can be attributed to three categories:

Manufacturing defects: A batch of poor batteries(like Note7), problems with the assembly line, damage to the components, or the use of the wrong components can lead to equipment problems. Although the media likes to blame manufacturing for the fire and recall of equipment, in fact manufacturing rarely causes such problems because well-known manufacturers have a strict safety check.

Design flaws or counterfeit products: In general, only cheap, poorly built equipment can have this problem. Some manufacturers do not have the technology to make products, and some companies are opportunistic. Look at eBay and Amazon, which products are everywhere, which work well and which are not, it's hard for ordinary people to tell, and many times the device has a fake logo, so it's hard to tell. Most cheap and counterfeit products work poorly, there is no safety technology, and well-known manufacturers have safety features.

-- Product damage when used: Why does the product become unsafe? Inappropriate use by end-users is the main cause. Toss equipment everywhere, get wet, charge with the wrong charger, and expose it to the sun should all be avoided.

Good equipment has safety features that prevent equipment from overheating, prevent overcharging, avoid excessive discharge, prevent short circuits, and can not be charged with the wrong charger. With these technologies, damaged equipment will not become dangerous equipment, but it is not 100 % safe.

What if it protects you and your family?

I don't expect you to spend thousands of dollars on testing equipment. Even so, you can still spot most of the threats. In fact, I can visually identify 90 % of unsafe devices.

There are a number of reasons that can cause the device to catch fire and explode. We can eliminate these factors. Here are some methods:

1, buy products from well-known retailers. You may spend a little more on a good charger or cable, but it's worth it because it will protect your life and make your family safer. Don't buy from eBay or Amazon. Don't use devices that are cheap and of poor quality if you doubt it.

Do not use the equipment if it is damaged or if there are any signs of overheating, expansion or deformation. This also applies to chargers and wires. Some of the equipment was unsafe and I couldn't find it, mainly because the damage was not visible. I suggest you check the equipment once a year and replace the damaged products in time.

Do not let the equipment too hot, especially when charging too hot. Don't charge your smartphone in your pocket or sports bag. Don't charge it on your dashboard while you're in the sun.

Don't charge the equipment when no one is looking. Most people don't do that, and I suggest you at least keep the charged device away from the combustible. Small lithium batteries can quickly ignite wooden tables, or bedroom furniture, leading to disaster.

If the equipment is recalled by the manufacturer, please follow the instructions of the manufacturer.

If there is any doubt, ask a professional for help.

Lithium-ion batteries can start fire quickly, and the risk factor is high. Do not underestimate it. Look at this video, you will know that lithium batteries are terrible, it is installed in a remote-controlled aircraft, the original good, a flash of fire.

If you're really unlucky and the electronics are on fire, here's what you can do:

Don't Water the Fire: Watering will only make things worse. Use a ClosD fire extinguisher or fire blanket.

Don't breathe in the smoke.

Don't be silly, don't be a hero, call the fire department in time.

Again, electronics are generally extremely safe, and if you're too worried to sleep, there's no need. Buying products from well-known brands from reliable places, do not misuse or harm equipment, generally there will be no problem.
