In 2012, the European Process Safety Centre (EPSC) published Making the case for leading indicators in process safety which is a pamphlet on the selection, development, and implementation of leading indicators for process safety. The document contains details on the type and spread of indicators which EPSC members have established within their own companies. In addition, EPSC provided several practical tips for the do's and don'ts of successful implementation including presentation of data and engagement of staff. This article is to develop these aspects further while exploring the relationship between leading indicators on a plant, business unit, and corporate level. Additionally, the interaction between leading and lagging indicators is to be highlighted alongside the management space which process safety indicators now inhabit with respect to monitoring and audit/review activities.
