OCI Nitrogen aims to build up knowledge of (leading, proactive) indicators that provide insight into the process safety performance of the ammonia production process. Three sub-studies have already been published in TtA. The main question of this sub-study is whether major accidents in the ammonia production process can be predicted from organizational factors, also called management delivery systems. A detailed example in retrospect shows that this is possible. Qualitative information can be generated from audits or peer reviews conducted by internal and/ or external experts once every three to four years. In case of no major shortcomings or findings, it makes sense to measure quantitatively. Based on established threshold values, (management) indicators can then be determined. However, determining threshold values is not easy because the influence of organizational factors on the accident processes is difficult to determine. Much (retrospective) investigation into incidents is still needed to be able to standardize this.
