Dr. M. Sam Mannan is one of the true pioneers in the process safety area, spending almost his entire lifetime in process safety and risk research. He was dedicated to ‘make safety second nature’ and published an impressive body of work. An overview of his research helps understanding the process safety area and provides insight in the legacy of this process safety pioneer. In this paper, 327 publications authored by Dr. Mannan from 1999 to 2019 in Web of Science core collection were downloaded and visually analyzed from four perspectives: his publication outputs, collaboration networks, topic areas, and highly cited papers and cited references. The results show a rapidly increasing trend in his research activity, mostly through journal publications. He published in 53 different outlets, with Journal of Loss Prevention in the Process Industries being most frequently selected. Dr. Mannan had a very active and diverse worldwide network, and collaborated with 18 different countries/regions, nearly 90 different institutions and 387 authors. His publications addressed process safety-related topics widely, including safety related to liquefied natural gas, explosions, runaway reactions, inherent safety, flammability and aerosol, and more recently resilience. Dr. Mannan's most cited paper focused on ‘fuzzy risk matrix’, whereas the most frequently cited reference in his work is ‘thermal hazard evaluation by an accelerating rate calorimeter’ by Townsend DI in 1980. Based on his most recent research activity, promising future directions for process safety research include resilience linked to risk assessment and management, for instance through the ‘safety triad’ concept he promoted shortly before passing away.

M. Sam Mannan博士是过程安全领域的真正开拓者之一，几乎一生都致力于过程安全和风险研究。他致力于“使安全成为第二性”，并发表了令人印象深刻的作品。他的研究概述有助于了解过程安全领域，并提供有关该过程安全先驱遗留下来的见识。在本文中，Mannan博士从1999年至2019年在Web of Science核心收藏中撰写了327种出版物，并从四个角度对其进行了可视化分析：他的出版物输出，协作网络，主题领域以及被高引用的论文和引用的参考文献。结果显示出他的研究活动迅速增长的趋势，主要是通过期刊出版物。他在53个不同的刊物上发表了论文， 流程工业被最频繁地选择。曼南博士拥有非常活跃且多元化的全球网络，并与18个不同的国家/地区，近90个不同的机构和387位作者合作。他的出版物广泛涉及与过程安全相关的主题，包括与液化天然气，爆炸，失控反应，固有安全性，易燃性和气雾剂有关的安全性，以及最近的韧性。Mannan博士被引用最多的论文集中在“模糊风险矩阵”上，而他的工作中被引用最多的参考文献是Townsend DI在1980年进行的“通过加速量热仪进行热危害评估”。根据他的最新研究活动，有希望的未来过程安全研究的方向包括与风险评估和管理相关的弹性，
