| Abstract Safety Critical Task Analysis (SCTA) is a structured activity, used to identify and mitigate risks associated with human actions / inactions for critical tasks on Major Accident Hazards (MAH). SCTA is widely accepted as part of a project in high-hazard industries (e.g. chemical processing and oil & gas) and is most often allocated to the Human Factors Engineering (HFE) scope of work. The common methods, now widely accepted (thanks to efforts from a generation of HFE evangelists) include references to human error / failures, Performance Influencing Factors (PIFs) and a range of psychological and socio-technical influences / drivers / responses. As HFE professionals we must very strongly focus and develop these human-centred areas of risk management because the designers, technicians and engineering disciplines involved in the assessments do not have the training, skills or focus to do so. The outcome of either sidelining or promoting solutions requiring psychological consideration, is compared in 2 case studies. |
