Bow-tie Technology Analysis of Safety Risks of Lithium-ion Battery in Air Transport

With the progress of science and technology and the vigorous development of civil aviation industry, the unsafe incidents caused by lithium batteries are gradually increasing. Lithium batteries account for a very high proportion in the statistics of the types of unsafe incidents involved in dangerous goods and in the transport volume of dangerous goods in domestic airlines. By studying the air transport routes of lithium batteries and the statistical analysis of the unsafe events occurring in each route, the risk sources of the unsafe incidents of lithium batteries were identified. Combined with the structural characteristics of Bow-tie risk technology, the Bow-tie safety risk model was constructed, which was suitable for the safety incident of lithium batteries in civil aviation transportation as the top event. The model is carried out in the transportation of lithium batteries in civil aviation according to the priority of eliminating the source of danger, preventing the risk before the accident, and preventing the deterioration of the control after the accident, respectively taking the lithium battery cargo unsafe event and the lithium battery luggage unsafe event as the top event. It has certain guiding value and practical significance for risk management, staff training, emergency treatment and accident investigation and analysis summary of civil aviation dangerous goods transport. The established model can also be improved and extended in civil aviation industry and other industries, which has great application value for effectively controlling accident probability and improving safety management level.
