Abstract The first European Loss Prevention Symposium under the auspices of the European Federation of Chemical Engineering (EFCE) took place in 1974 in the then new Aula of the Delft University of Technology in the Netherlands. After the triennial symposium over a period of 45 years having been organized in several European cities, it returned in 2019 to the Delft Aula. Authors of this paper are members of EFCE Loss Prevention Working Party organizing the LP Symposia and after nearly half century, it is therefore worthwhile to look back and also to look forward, following the evolution of process safety. This paper presents an impression of the changes in process safety, risk management approaches, and methods over that 45-year period, while at the same time the last symposium contributions are briefly reviewed and a few highlights, called breakthroughs, are identified.

代尔夫特 1974 年和 2019 年欧洲损失预防研讨会：从第 1 次到第 16 次 LPS 过程安全演变变化的亮点和印象

摘要 由欧洲化学工程联合会 (EFCE) 主办的第一届欧洲防损研讨会于 1974 年在荷兰代尔夫特理工大学的新 Aula 举行。在欧洲几个城市举办了为期 45 年的三年一次的研讨会后，它于 2019 年回到代尔夫特奥拉。本文的作者是组织 LP 研讨会的 EFCE 损失预防工作组的成员，因此在近半个世纪之后，随着过程安全的发展，回顾和展望是值得的。本文介绍了 45 年间过程安全、风险管理方法和方法的变化，同时简要回顾了上次研讨会的贡献和一些重点，
