Occupational Safety and Health (OSH) and process safety are traditionally separated by a fuzzy perimeter, and the need to adopt different management approaches is emphasised in the literature. However, OSH and process safety complement rather than replace each other, and their integration may achieve total safety excellence of organisations. The existing studies about this integration focus on various aspects of the risk management process and provide different types of outputs. In such a context, this paper has the objective to propose IMPROSafety (Integrated risk Management for PRocess and Occupational Safety), a risk-based framework to integrate OSH and process safety. We expand the traditional risk definition considering scenario identification, its occurrence probability, and its consequence severity, to also include other dimensions, i.e. the temporal evolution and spatial extension of the scenario, and the number of workers involved. The framework covers all the steps of the risk management process: hazard identification is performed thanks to the bow-tie chaining structure and the application of the energy theory perspective, risk estimation via quantitative analyses of the considered dimensions, risk evaluation by means of the ranking of each dimension and an overall risk level, and risk treatment through a proper safety measure identification. A case study about three real events occurred in the steel and iron industry in the last decades is used to test the IMPROSafety framework. The investigation of six scenarios highlights the most dominant event sequences and risk dimensions that should receive prioritised attention for developing effective risk reduction controls.

IMPROSafety:基于风险的整合职业和过程安全的框架

职业安全与健康 (OSH) 和过程安全传统上由模糊边界分隔,文献中强调需要采用不同的管理方法。然而,职业安全与卫生和过程安全是相互补充而不是相互替代的,它们的整合可以实现组织的整体安全卓越。关于这种整合的现有研究侧重于风险管理过程的各个方面,并提供不同类型的输出。在这样的背景下,本文的目标是提出 IMPROSafety(过程和职业安全的综合风险管理),这是一个基于风险的框架,用于整合职业安全与健康和过程安全。我们将考虑情景识别、发生概率和后果严重性的传统风险定义扩展到其他维度,即 场景的时间演变和空间扩展,以及涉及的工人数量。该框架涵盖了风险管理过程的所有步骤:通过蝴蝶结链结构和能量理论视角的应用进行危险识别,通过对所考虑维度的定量分析进行风险评估,通过排名进行风险评估每个维度和整体风险级别,并通过适当的安全措施识别进行风险处理。过去几十年钢铁行业发生的三个真实事件的案例研究用于测试 IMPROSafety 框架。六种情景的调查突出了最主要的事件序列和风险维度,在制定有效的风险降低控制时应优先关注这些事件序列和风险维度。
