摘要总结AI 辅助解读
本条款定义了美国运输部（DOT）危险品法规中的第9类杂项危险物质。其核心逻辑为“兜底定义”：凡在运输过程中呈现危险性，但不符合其他任何特定危险类别（如爆炸品、易燃液体等）定义的物质，均归入此类。具体涵盖两类情形：一是具有麻醉性、有害性或类似特性，可能导致机组人员极度不适或烦恼从而妨碍履职的材料；二是符合§171.8定义的高温材料、有害物质、危险废物或海洋污染物。该定义直接决定了货物的分类申报义务及包装要求。
For the purposes of this subchapter, miscellaneous hazardous material (Class 9) means a material which presents a hazard during transportation but which does not meet the definition of any other hazard class. This class includes:
- (a) Any material which has an anesthetic, noxious or other similar property which could cause extreme annoyance or discomfort to a flight crew member so as to prevent the correct performance of assigned duties; or
- (b) Any material that meets the definition in § 171.8 of this subchapter for an elevated temperature material, a hazardous substance, a hazardous waste, or a marine pollutant.
