So close! At the Shanghai airport jet bridge, a passenger's backpack suddenly caught fire...
10月20日下午上海虹桥机场T2航站楼一进港航班下客时廊桥内突然起火Suspected of spontaneous combustion of the charging treasure机场工作人员赶到将火扑灭疏散旅客机上人员一切正常
据华龙网报道,机上乘客徐先生告诉记者,该航班为CA2821,14:55从天津滨海机场起飞,16:28抵达上海虹桥机场,航班起降阶段一切正常,但在下机时出现了意外。
“我下飞机走到廊桥中间时,一名乘客的书包突然着了起来,**火势瞬间变大,燃起滚滚浓烟,**密闭的廊桥被浓烟灌满,后面还有人不断挤出来,前面也走不出去,工作人员还没来,有一瞬间感觉自己呼吸不过来要窒息了。”
Don't use charging treasure while flying**** **飞机客舱属于增压环境,**在飞机起降过程中,客舱压力是变化的,会从起飞前的1个大气压降到巡航时的约0.6个大气压,降落时再慢慢增加到1个大气压。
在这种环境下充电宝中的锂电池会产生变化,**此时如果使用充电宝,容易导致发热、增加自燃的概率,**危害飞行安全。
充电宝“上”飞机,有哪些规定?
**关于容量:**飞机上充电宝的容量有严格的限制。额定能量不超过100Wh(瓦时),无需航空公司批准;额定能量超过100Wh但不超过160Wh,经航空公司批准后方可携带。However, power banks larger than the specified capacity are not allowed on the plane.
**关于携带:**充电宝必须是旅客个人自用携带;充电宝只能在手提行李中携带或随身携带,严禁在托运行李中携带。同时需要注意,Each passenger is allowed to carry no more than two power banks.
Usage: During the flight, it is prohibited to use power banks to charge electronic devices. For power banks with a start-up switch, the power bank should remain turned off throughout the flight.
What situations are prone to explosion and combustion in power banks?
inferior products
充电宝主要由电芯、电路板和外壳三部分组成。其中,电芯的主要材质是锂离子电池或锂聚合物电池。不合格的电芯和电路板都有可能引发自燃甚至爆炸。根据国家规定,正规上市的充电宝必须取得3C强制认证,并且标注在产品上。
此外,如果充电宝的外壳质量不过关,一旦发生挤压、冲击、针刺或磕碰、跌落,充电宝内部电路和电芯极易出现短路、电芯漏液等问题,从而发生剧烈反应,就可能造成Smoke, fire, explosion.等严重后果。
overcharge time
Power banks usually take several hours or even longer to fully charge. If the charger is left plugged in, charging the power bank all day and night, the battery will be in a state of overcharging, which can easily lead to circuit malfunctions and subsequently cause explosions.
overheated
充电时,如果将充电宝Placed in environments such as quilts, boxes, etc., which are not conducive to heat dissipation.,或将充电宝placed in high-temperature areas below the sun,都有可能引发充电宝的自燃爆炸。
充电宝平时应存放在Moderate temperature, dry.的地方,防止暴晒,Its optimal operating temperature is ℃.
How to extinguish a power bank fire? Moisture, crushing impact, damage, high temperature都可能引起充电宝起火。如果遇到充电宝起火,该采用哪种灭火方式呢?
充电宝的电芯通常由几块锂电池拼接组成,即便一块电池的火熄灭,残余的高温也可能引燃旁边的锂电池。
干粉灭火器的渗透性和降温效果比较差,在应对充电宝着火时效果并不理想,而water能够渗透到充电宝内部,有效灭火并起到降温作用。
The charging treasure has a useful life 如何避免充电宝变“充电爆”?
Purchase regular products
正规厂商的产品包装上都会有厂家生产地址、电话、防伪码、条形码等信息,另外还要Please pay attention to the presence or absence of the "" marks.。
Daily standardized use
Do not exceed the service life
在充电宝的一侧,通常有可循环使用标识,The middle number represents the rechargeable lifespan of the battery inside the power bank.

充电宝作为消耗品,在频繁使用中超过可循环使用年限的话,其内部电池可能会出现异常。
带充电宝乘飞机请务必严守规范Disable charging treasure during flight日常使用也要注意Timely replace hidden charging treasure确保安全
