On February 25, when China Southern Airlines flew from Guangzhou to Shanghai, the luggage rack caught fire. After investigation, a passenger with a charging treasure smoked and caught fire. The passengers involved were taken away by the police and the flight was replaced by aircraft and crew.
 
After the spontaneous combustion incident, the question of flight safety is naturally the first to bear the brunt. Previously, the Samsung Note7 mobile phone explosion problem once allowed the civil aviation administration to make a ban on carrying the Samsung Note7 mobile phone. Then, is it possible to give a similar ban to the indifferent and uneven charging treasure? This is probably not realistic. From a safety point of view, since lithium batteries have a risk of use, it is undoubtedly the best way to carry them. However, because appliances such as charging treasures are widely used, it is forbidden to bring them to the aircraft, which may cause great inconvenience to passengers. If the charging treasure is to be banned, should the mobile phone be banned? Lithium batteries are used for charging treasures, and lithium batteries are also used for mobile phones. The security risks they face are not much different.
 
Not allowing inferior goods to be on the machine may be a workaround. The problem is that airlines and airports are not professionals. It is also difficult for them to judge what kind of charging treasure is inferior. What kind of charging treasure is safe. Look at the brand? The brand is not a safe ticket, the brand is as big as Samsung, and its battery is also exploding. Therefore, the best prevention method is to strengthen the safety of the lithium battery itself, which requires the safety of the production company to the supervision department. These basic work cannot be expected to be resolved at the gate.
 
In the dangerous situation of China Southern Airlines, because of the timely and professional disposal, the danger did not lead to a bigger disaster. But the impact of this incident far exceeded the plane. With the wide application of lithium batteries and the closeness of the people's lives, it has reached the point of ubiquity. On the plane it is related to flight safety, and in another scene, it may also be related to personal safety at home. Someone needs to be reminded of the public, and more professional knowledge is needed. For example, the fire-fighting problem, some netizens spit the stewardess to use the mineral water to extinguish the fire. "It is very unprofessional." Some people question whether there is no fire extinguisher on the plane. After the expert explained it, the public understood the truth. Regarding the issue of how to extinguish the lithium battery on the aircraft, the standard operation recommended by the CAAC is to use water fire extinguishing as the first choice for emergency disposal, because it can eliminate the open flame and have a certain cooling effect. In other words, the flight attendant is not only right, but also the best solution. The flight attendant is always providing catering services, so using mineral water can be said to be the quickest and most effective disposal method. The netizen said that “using a foam fire extinguisher” is an extremely dangerous operation because the sprayed foam adheres to the periphery of the battery to form a thermal insulator, which increases the chemical reaction and generates more heat.
 
Through such a questioning and dispelling process, the knowledge of fire extinguishing of lithium batteries has gained more popularity, which is also an unexpected harvest beyond accidents. Don't underestimate the science process like this, it may play a role at a critical moment.
 
This dangerous situation has also exposed the problems that are easily overlooked by everyone. Charging treasures are now basically standard for the family. Prices are high and low, the quality is uneven, but there is a lot of randomness in use, there is a charge in the bed, there are random littering. How to use it is safe, how to carry it is not easy to cause problems? The self-ignition of the charging treasure on the luggage rack was promptly found to be disposed of in time to avoid a bigger disaster. However, the charging treasure in the home is often stored without attention. Is the placement environment safe? Whether the public has the ability to handle such a flight attendant is really a problem.
