Designing a Human Factors Investigation Tool to Improve the Quality of Safety Reporting
Engineers in the UK offshore oil industry endeavour to analyse the causes of accidents with regard to the human and organisational factors. However, their expertise tends to lie in the analysis of the technical failures. In an attempt to improve the investigation of the human factors causes of accidents, a human factors investigation system was developed for the UK Health and Safety Executive and five oil companies. The development and evaluation of two previous reporting systems provides the background to this current study, where both systems were found to increase the quantity of human factors information collected. The Human Factors Investigation Tool (HFIT) improves on these two systems, where it collects four types of human factors information including (i) the observable errors occurring immediately prior to the incident, (ii) the error recovery process, (iii) the information processing stage at which the error occurred and (iv) the underlying causes.
