HumHID is a hazard identification process that uses cognitive work analysis techniques and human factors/error taxonomy information to help identify human related hazards and the possible causes of them so designs can be modified to mitigate or tolerate such hazards. To facilitate the usability of HumHID, a software tool was constructed to guide users through the methodology and to automate otherwise tedious activities. An initial pilot study of the HumHID method and tool was conducted with industrial personnel on an industry case study to assess its usability and usefulness prior to conducting a full case study. The feasibility trial results showed that, with some further improvements, the method and software tool could help process organisations identify human factors issues.
INTRODUCTIONUnacceptable accidents still occur in the process industry. These accidents are often caused by abnormal situations arising from an interaction of people, plant and procedure factors. To address such accidents, process industries need a usable and useful method for identifying human related hazards that can be integrated with plant and procedure hazard identification processes, such as the BLHAZID method (Seligmann et al., 2009(Seligmann et al., , 2010, to reduce the occurrence of unacceptable accidents. We are developing the HumHID methodology to address this need (Hassall et al., 2010). HumHID is unique in the fact that it (1) it uses formative, cognitive work analysis (CWA) techniques and recently published human factors/errors taxonomy information to facilitate the identification and analysis of human related hazards for anticipated and unanticipated situations; (2) it is structured to be used as a standalone or integrated method; and (3) it produces output that can provide guidance on ways to mitigate or tolerate the identified hazards.To facilitate the usability of the HumHID methodology we developed a prototype software tool, using a customised Microsoft Excel workbook, to guide the user through the process and to automate tedious or repetitive activity. A series of industry testing, ranging from an initial pilot study to full case studies, are necessary to determine the usability and usefulness of HumHID for industry. This paper outlines the HumHID process, provides details of the HumHID tool and then discusses some results from an initial pilot study that was performed at BlueScope Steel's (BSL) coke making operations (Port Kembla, Australia).
