While preparing 10 600 L of a 25% aqueous solution of sodium chlorite (NaClO₂), the solid salt was spilled and not cleaned up promptly. Combustible materials, including cardboard sheets and polypropylene fabric, became contaminated with solid sodium chlorite. Subsequently, a spark, initiated by inadvertently striking metal drum sealing rings together, ignited the oxidizer-contaminated combustible materials. The fire spread to a polypropylene bag containing 800 kg of sodium chlorite. The contents of the bag detonated causing one fatality, two serious injuries, and extensive property damage. The incident was thoroughly investigated, leading to the conclusion that a series of process safety management failures occurred which created the conditions driving the incident. The investigation is summarized and discussed, with an emphasis on the investigation procedures used to support the root cause analysis and conclusions. Recommendations are provided to help prevent similar incidents.

亚氯酸钠处理不当导致死亡

同时制备 10 600 L 25% 的亚氯酸钠水溶液 (NaClO ₂)，固体盐洒落而没有及时清理干净。可燃材料，包括纸板和聚丙烯织物，被固体亚氯酸钠污染。随后，由于不经意间将金属鼓密封环撞击在一起而引发的火花点燃了被氧化剂污染的可燃材料。火势蔓延到一个装有 800 公斤亚氯酸钠的聚丙烯袋子上。袋子里的东西爆炸了，造成 1 人死亡、2 人重伤和大量财产损失。对事件进行了彻底调查，得出的结论是，发生了一系列过程安全管理失误，为事件的发生创造了条件。对调查进行了总结和讨论，重点是用于支持根本原因分析和结论的调查程序。
