Abstract: In order to guarantee air transport safety, the air transport hazard of self-heating bag is investigated. Taking two kinds of self-heating bags as instance, instrumental analyses, chemical experiments and dangerous property tests are conducted to analyze the components, self-heating principles and typical hazard of the self-heating bags.Results show that the regulations of DGR issued by IATA could effectively recognize the hazard of self-heating bags in air transport both as goods and carry-on luggage. The clarified safety conditions provide reference for air transport practice and standard regulation of suspected or hidden dangerous goods.

Key words: air transport safety, dangerous goods, self-heating food, self-heating bag
