充电宝冒烟致航班返航 确保安全务必注意这几点→

Core Viewpoint - The incident involving a passenger's camera battery and power bank smoking on a China Southern Airlines flight highlights the safety risks associated with carrying lithium batteries on airplanes, emphasizing the need for strict adherence to regulations and proper usage guidelines [1][3]. Group 1: Incident Overview - A passenger on flight CZ6850 from Hangzhou to Shenzhen experienced smoke from a camera battery and power bank, prompting the crew to return safely after 15 minutes of flight [1][3]. - The cabin environment changes pressure during takeoff and landing, which can affect lithium batteries, increasing the risk of overheating and self-ignition [4]. Group 2: Regulations for Carrying Power Banks - Power banks must have a rated energy not exceeding 100Wh to be carried without airline approval; those between 100Wh and 160Wh require approval, while those over 160Wh are prohibited [5]. - Power banks must be carried in hand luggage, and each passenger is limited to two power banks [5]. Group 3: Risks Associated with Power Banks - Poor-quality power banks can lead to self-ignition or explosions due to defective components, emphasizing the importance of purchasing certified products [6]. - Overcharging and overheating are significant risks; leaving a power bank plugged in for extended periods can cause circuit failures and fires [9][10]. Group 4: Fire Safety and Prevention - In case of a fire, water is more effective than dry powder extinguishers for extinguishing power bank fires due to its ability to penetrate and cool the device [12]. - Regularly check the usage duration of power banks, as exceeding their lifespan can lead to malfunctions and safety hazards [19].
