November 12, 2014, 6:30pm, another incident of spontaneous combustion caused by a power bank occurred in domestic security check channel at Terminal 3. This is the 3rd similar event in Capital Airport this year.
That morning, when a passenger was passing the domestic security check channel in Terminal 3, a power bank without clear identification was found in his baggage. Security staff explained relevant rules to the passenger and told him that power banks with unclear identification were not allowed to be carried onto the flight due to possible safety risk. However, without following the instruction of security staff, the passenger insisted on opening his power bank, leading to autoignition. Security staff took immediate measures to put out fire and evacuated other passengers. The passenger was detained and taken away by the police. Fortunately, the operation of the security check channel was back to normal immediately after clearing up and other security check channels were not affected.
In order to ensure air transport safety, in accordance with existing “Technical Instructions for the Safe Transport of Dangerous Goods by Air” issued by ICAO, and “Provisions of the Civil Aviation Administration of China on the Administration of Transport of Dangerous Goods By Air”, Civil Aviation Administration of China, on August 7, has issued relevant regulations to regulate air passengers and crew members carrying power banks on to flights. The rated energy of power banks which can be carried on board is restricted and identification method for rated power has also been specified. For details, see the “Announcement of Rules for Air Passengers Carrying Power Bank onto Flights”.
Capital Airport reminds all passengers to pay attention to potential safety hazard of the power banks without clear identification in flights. To ensure safety, please check the rated power of your lithium battery (include power bank) before travel. The specific calculation method for rated power is as follows: Rated Power (Wh)= Nominal Voltage（V）× Nominal Capacity(Ah). The lithium battery (include power bank) with rated power ranging between 100WH and 160WH should be approved by air carrier. The power banks with rated power exceeding 160WH or power banks without clear identification are not allowed to be carried on board or consigned. The power banks without clear identification or with rated power unable to be worked out with the marked parameters are not allowed to be carried to the airport. At the same time, passengers shall follow the instructions of security staff during the security check, so as to avoid the occurrence of the similar incidence.
“Announcement of Rules for Air Passengers Carrying Power Bank onto Flights”
1. Power bank must be carried for personal use.
2. Power bank must only be carried in hand luggage or carried around. It is not allowed to carry power banks in checked luggage.
3. If the rated power is less than 100WH, power banks can be carried without approval; power banks with the power between 100WH and 160WH can be carried after approval of air carrier. However, each passenger is only allowed to carry no more than two power banks.
4. It is not allowed to carry the power banks with power higher than 160WH or the power banks without identified rated power and with rated power unable to be worked out with the marked parameters.
5. Passengers are not allowed to use power banks to charge electronic devices during the course of the flight. Power banks must be switched “Off” during the course of the flight.
Above mentioned regulations are also applicable for crew members.
This announcement shall take effect from the date of its promulgation.

Calculation methods for the rated power of power banks
If the rated power is not directly marked, the calculation methods are as follows:
1. If Nominal Voltage (V) and Nominal Capacity (Ah) are given, the rated power can be calculated as follows:
Nominal Voltage and Nominal Capacity are usually marked on power banks.
2. If only milliampere (mAh) is given, please divide the number by 1,000, and you get ampere-hour (Ah).
For example: Nominal Voltage is 3.7 and Nominal Capacity is 760mAh, and then you get the rated power:
760 mAh÷ 1000 = 0.76Ah
