The earliest fire of the earphones is the lithium battery. According to media reports, a female passenger recently took a flight from Beijing to Melbourne on a flight from Australia. Two hours after taking off, the headphones she wore exploded. The reporter saw in the pictures disclosed by the media that the female passenger had burns on the neck and back of the hand, some of the hair was burnt, and the cheeks near the ears were blackened. According to reports, she was asleep at the time and was awakened by the explosion. She took off her headphones and threw it on the floor. The headphones were on Mars and the plastic began to melt. The crew immediately poured a bucket of water on the burning earphones, and the molten battery and plastic casing were glued to the ground. The cabin was filled with plastic melting and electrical and hair burning smell. The announcement issued on the website of the Australian Transportation Security Agency did not specify the brand of the fire headset, but believed that the culprit was the lithium-ion battery used by the headset. It seems that the female passenger is better off not using a Bluetooth headset to use the wired headset directly. In recent years, batteries in smart phones and accessories have been overheated, spontaneously burned, and exploded. South Korea’s Samsung’s Note7 mobile phone battery was overheated and fires frequently, which led to the civil aviation administration’s order prohibiting the use of this mobile phone. Samsung finally announced the recall and discontinued Note 7. In 2016, a Sydney Qatar Airways airport was preparing to take off. The company’s flight cabin found a piece of hand luggage smoking, and later found out that the lithium battery in the bag caught fire. In the United States, there has also been an accident in which electronic devices that fell on the ground were squeezed and smoked. At present, the regulations generally adopted by the international civil aviation industry are battery-powered mobile electronic devices such as mobile phones, laptop computers, tablet computers, watches, cameras, and the like, and the mobile charging devices that have arisen in recent years must be carried in portable luggage. In addition, the batteries must be individually packaged separately to avoid short-circuit fires. Lithium-ion batteries are small in size and light in weight, but have a large capacity. They have gradually replaced batteries made of nickel-cadmium and other materials since the early 1990s. However, lithium batteries are prone to "thermal runaway" because they contain all the components that can cause a fire in a small volume of the battery: carbon, oxygen, and a flammable liquid, a lithium salt electrolyte. As early as 2004, the safety hazard of lithium batteries prompted the US Federal Aviation Administration to prohibit the loading of lithium-ion batteries in the cargo compartment of passenger aircraft, but passengers can still carry laptops or mobile phones with them when they board the aircraft. There is no less security in the security check. Mobile power, that is, "charging treasure", generally uses lithium batteries as a storage unit, which is convenient to use, and is also a must-have item for many "flying trapeze". However, just because of its "belly" lithium battery, it also brings safety risks to the flight of domestic airlines, bringing a lot of trouble to the airport security inspection work. On February 18, 2017, on a flight from Harbin to Nagoya in Spring Airlines, a passenger’s charging treasure suddenly caught fire, forcing the flight to drop to Shenyang Airport. Fortunately, after the incident, the crew used fire extinguishers to extinguish the fire. On March 5, 2017, on the China Southern Airlines flight from Nanning to Bangkok, a smoke incident occurred on a charging treasure aircraft. Due to the proper disposal of the crew, the flight was safely closed and a serious safety incident was avoided. On the morning of November 12, 2014, a male passenger was prohibited from carrying a non-marking charging treasure at the domestic security checkpoint of Terminal 3 of the Capital Airport. After the security inspector explained the relevant regulations and the security risks of the item, the passenger did not listen to dissuade and disassemble the charging treasure, causing the charging treasure to smoke. The on-site squad leader immediately extinguished using the fire extinguisher configured on site, and the security inspector quickly took out the fire blanket to cover the charging treasure, and evacuated the passengers in the passage to other channels for inspection. At 9:57 on August 5, 2014, a male passenger was inspected on the No. 10 channel of T3C. At this time, the image of the X-ray machine showed that there was a charging treasure in the clothing basket. The opener Meng Yanhong checked the charging treasure. For the unmarked charging treasure, after explaining the relevant regulations and the safety risks of the item to the passenger, at 10:01, the passenger does not listen to dissuade and disassemble and throw the separated charging treasure onto the metal guiding belt at the rear end of the X-ray machine, leaving the scene. . At 10:01:50, the charging treasure smoked. Meng Yanhong immediately placed the nearby baggage in a safe area and reported it to the squad leader Li Yan. Then Li Yan took out the fire extinguisher and handed it to the support squad leader Zhang Aimin to extinguish the fire. On August 14, 2015, the Civil Aviation Administration issued a notice on reaffirming the passengers carrying the charging treasure and the fire in the civil aviation. Please check the carry-on and checked baggage before the trip, and strictly observe the relevant regulations for safe flight. The Civil Aviation Administration reaffirmed that the passengers carry the "Charging Po" flight regulations and the Civil Aviation Administration reiterated that the prohibition of passengers carrying lighters and matches is as follows: 1. It is strictly forbidden to carry charging treasures in checked baggage. 2. It is strictly forbidden to carry a charging treasure with a rated energy exceeding 160Wh; a charging treasure with a rated energy exceeding 100Wh but not exceeding 160Wh must be approved by the airline and must not exceed two. 3. It is strictly forbidden to carry a charging treasure with unclear identification. 4. It is strictly forbidden to use the charging treasure during the flight. 5. It is strictly forbidden to carry the charging treasure for non-personal purposes. For those who violate the above provisions, the public security organs will seriously deal with them according to the relevant laws and regulations of the state according to the circumstances. The above provisions apply to the crew at the same time. It is worth noting that when the portable charging and lithium battery with the rated energy is greater than 100Wh and less than or equal to 160Wh, it must be approved by the airline before being carried, and each person is limited to two. Nominal energy than 160Wh, nominal energy or not marked, but also other parameters can not be marked calculated target energy charging Po, is not capable of carrying lithium battery check. Conversion formula: rated energy (Wh) = nominal voltage (V) * nominal capacity (Ah) (Note: Ah = mAh / 1000). Small battery involves big safety Liu Xiaoqiang, manager of the West District Security Department of Beijing Capital Airport Aviation Security Co., Ltd. told reporters that aviation flight safety is the first, and it is necessary to completely eliminate dangerous goods "boarding" that do not meet the requirements of civil aviation. First of all, lighters and matches are self-evident for the threat of air transport safety. For a long time, the Civil Aviation Authority has forbidden passengers to carry and carry lighters and matches. Secondly, in recent years, with the popularization of electronic products such as smart phones and tablet computers, lithium batteries and charging treasures have appeared more and more in the "bags" of the people. However, many passengers do not understand that lithium is a kind of active metal, and it may spontaneously ignite when exposed to heat at high altitude. In addition, the quality of lithium batteries and charging treasures are uneven, and their own safety protection measures are not perfect. If dangerous goods such as lithium batteries and charging treasures are checked in baggage, the baggage will be squeezed and collided in a small cargo space, which may easily cause spontaneous combustion or explosion, which is a major safety hazard that threatens the flight safety. "From August 16, 2015, the Capital Airport will place detailed Chinese and English "Notice of Passengers" on the check-in counter to remind passengers to set up billboards in the conspicuous position in the terminal building to publicize dangerous air transport knowledge. ." For air transportation of light goods such as lighters, lithium batteries and charging treasures, ICAO has formulated the Technical Rules for Safe Air Transportation of Dangerous Goods. The Civil Aviation Administration has issued the Regulations on the Administration of Transportation of Dangerous Goods in China Civil Aviation. Inspection rules, etc., are clearly defined and restricted. Civil aviation industry experts said that according to relevant regulations, airlines, as carriers, have a clear obligation to provide passengers with information on the prohibition of air transport of dangerous goods when passengers purchase tickets. The check-in procedure can only be completed after the passenger has indicated that he has understood the dangerous goods restrictions in the baggage. Only airlines, airport companies, and ground service agents can work together to increase the intensity and check for vacancies to ensure the safety of air transportation. Battery explosions are caused by overheating caused by various reasons. To remind passengers to stop using and turn off the power immediately if they find that the temperature of the mobile phone or Bluetooth headset is too high. Pay attention to ventilation and use the electronic products in a confined space. 360 mobile phone security expert Fan suggested: "In addition, please note that the use of mobile phones when flying on the aircraft will cause signal interference to the aircraft, strictly obey the instructions of flight attendants, do not use any electronic equipment."
