摘　　要：简述大型液氧、液氮贮槽的常规安全措施,结合大型低温液体贮槽的爆炸事故,阐述在排液口设置重锤式快速切断阀和顶盖设计为薄弱结构的必要性及其作用,分析在大型液氧、液氮贮槽槽区不设安全围堰的可行性。The routine safety measures for large-sized liquefied oxygen and liquefied nitrogen tank are briefed. In combination with explosion accident of large-sized low-temperature liquid tank, the necessity to set a harmer type quick cut off valve at drain port and design the top cover as a weak structure and their reached effects are described, and the feasibility not to set a safe weir in the large-sized liquefied oxygen and liquefied nitrogen tank is analyzed.
