• Assessing the design of equipment layout and controls

    2009 - Gas onshore processing

    Andy was required to visit newly constructed buildings housing electrical and control equipment.  His brief was to ensure the arrangements were appropriate to minimise risk of human error.  Andy identified that a number of cabinets were not positioned in a logical order, and that some labelling was confusing and ambiguous.  He was able to make practical and cost effective recommendations that were accepted by the engineering team as worthwhile and achievable.

  • Assessment of the human errors in accidents


    2004 - Chemical manufacture

    The client was concerned that they were experiencing frequent incidents where human error was a cause. However, they did not understand why those errors were occurring and so did not know what to do to prevent them. Andy led a small team in assisting the client in analysing past incidents and suggesting preventative strategies. This required him to train his colleagues in the techniques to be used. The project started by assessing a selection of past incidents in order to identify if there were any recurrent themes. As well as his in depth knowledge of human factors, Andy able to provide a systematic approach to this assessment. From this, a number of error prone tasks were selected for further analysis. The error prone tasks were assessed using the 'Human Factors Assessment of safety critical tasks' methodology described in HSE report OTO 99:092. During workshops attended by site personnel, error prone tasks were assessed using Hierarchical Task Analysis (HTA) and Predictive Human Error Analysis (PHEA). From this, error reduction strategies were proposed.
