文章对两起氨制冷设备回气集气管端管帽脱落,导致氨气大量泄漏,造成人员伤亡事故案例进行分析,找出了两起事故同样的原因。为了防止同类事故的发生,消除管理盲区和事故隐患,从设计、制造、检验、管理等方面提出了防范措施,供制冷设备设计、制造、使用、安全监察部门参考。
The article sheds the gas cap end caps on two ammonia refrigeration equipment, resulting in the massive leakage of ammonia gas, causing the casualty accident cases to be analyzed and finding out the same reasons for the two accidents. In order to prevent the occurrence of similar accidents and to eliminate the blind spots and potential hidden dangers in management, preventive measures are put forward in the aspects of design, manufacture, inspection and management for the reference of the design, manufacture, use and safety supervision departments of refrigeration equipment.
