Evaluative comparison of two methods for SADT determination (UN H.1 and H.4)

We present our results on the comparison of two methods for the SADT determination. Both methods, UN test H.1 and UN test H.4 are recommended by the international transport regulations from the UN. But during the last years the applicability of the UN test H.4 has been questioned for solid substances. Therefore, three organic peroxides and one self-reactive substance have been investigated in 5 kg and 20 kg packages as well as in the UN test H.4 in a 500 mL Dewar vessel. The SADT values determined with the different methods match. The UN test H.4 seems to be well suited for solid organic peroxides and self-reactive substances of at least 20 kg or 60 L.     

参加两个国际安全卫生会议的观感

本文介绍了1989年9月中下旬在瑞典召开的“世界第一届事故和伤害预防会议”和“职业事故预防对策国际会议”的概况和主要内容。重点介绍了第一个会议的概况和会议通过的《斯德哥尔摩宣言》,该宣言向全球提出了“安全——人人关心、人人有责”的口号,提出了创建“全球安全共同体”的设想及其四项实施建议。文章还阐述了作者的感想,并对加强我国安全卫生界与国际上同行专家的交流与合作提了建设性意见。
