Process safety incidents can result in injuries, fatalities, environmental impacts, facility damage, downtime & lost production, as well as impacts on a company's and industry's reputation. This study is focused on an analysis of the most commonly reported contributing factors to process safety incidents in the US chemical manufacturing industry. The database for the study contained 79 incidents from 2010 to 2019, partly investigated by the Chemical Safety Board (CSB). To be included in the study, the CSB archive of incident investigations were parsed to include only incidents which occurred at a company classified as 325 in the North American Industry Classification System (NAICS), assigned to businesses that participate in chemical manufacturing. For each incident, all of the identified contributing factors were catalogued in the database. From this list of identified contributing factors, it was possible to name the ‘top three’ contributing factors. The top three contributing factors cited for the chemical manufacturing industry were found to be: design; preventive maintenance; and safeguards, controls & layers of protection. The relationship between these top contributing factors and the most common OSHA citations was investigated as well. The investigation and citation history for NAICS 325 companies in the Occupational Safety & Health Administration (OSHA) citations database was then analysed to assess whether there was any overlap between the top reported contributing factors to process safety events and the top OSHA citations recorded for the industry. A database consisting of the inspection and citation history for the chemical manufacturing industry identified by NAICS code 325 was assembled for inspections occurring between 2010 and 2020 (August). The analysis of the citation history for the chemical manufacturing industry specifically, identified that the list of the top contributing factors to process safety incidents overlapped with the most common OSHA violations. This finding is relevant to industry stakeholders who are considering how to strategically invest resources for achieving maximum benefit – reducing process safety risk and simultaneously improving OSHA citation history.

过程安全事件可能会导致人员受伤，死亡，环境影响，设施损坏，停机时间和生产损失，以及对公司和行业声誉的影响。这项研究的重点是分析美国化学制造行业中最常报告的过程安全事件的影响因素。该研究的数据库包含2010年至2019年的79起事件，由化学安全委员会（CSB）进行了部分调查。为了包括在研究中，CSB事件调查档案被解析为仅包括在北美工业分类系统（NAICS）中被分类为325的公司中发生的事件，这些事件被分配给参与化学制造的企业。对于每个事件，所有确定的影响因素均已在数据库中分类。从已识别的影响因素列表中，可以将“前三名”影响因素命名。研究发现，对化工制造业而言，最重要的三个贡献因素是：设计；化学；化学；化学；化学；化学；化学；化学；化学；化学；化学。预防性的维护; 以及保障，控制和保护层。还研究了这些最重要的因素与最常见的OSHA引用之间的关系。然后，分析了美国职业安全与健康管理局（OSHA）引用数据库中NAICS 325公司的调查和引用历史，以评估报告的过程安全事件的主要贡献因素与该行业记录的OSHA顶级引用之间是否存在重叠。 。组装了由NAICS代码325标识的化学制造行业检查和引用历史记录的数据库，以进行2010年至2020年（8月）之间的检查。通过对化工制造业的引证历史进行专门分析，可以确定对过程安全事件影响最大的因素清单与最常见的OSHA违法行为重叠。该发现与正在考虑如何战略性地投资资源以实现最大利益的行业利益相关者有关，即减少过程安全风险并同时改善OSHA引用历史。通过对化工制造业的引证历史进行分析，可以确定对过程安全事件影响最大的因素清单与最常见的OSHA违法行为重叠。该发现与行业利益相关者有关，他们正在考虑如何战略性地投资资源以获得最大的利益-降低过程安全风险并同时改善OSHA引用历史。通过对化工制造业的引证历史进行分析，可以确定对过程安全事件影响最大的因素清单与最常见的OSHA违法行为重叠。该发现与行业利益相关者有关，他们正在考虑如何战略性地投资资源以获得最大的利益-降低过程安全风险并同时改善OSHA引用历史。
