DESIGN ERROR IN THE CHEMICAL INDUSTRY. RESULTS AND RECOMMENDATIONS FROM A PHD STUDY
Design errors in the chemical industry are found to be an important cause of accident, as already reported in Harrogate in 1983. However it seems possible to discover the majority of design errors by integrating already known risk analysis methods in the design process. These methods are not currently applied to all design projects. This is one of the results arising from direct observation and interviews in design and safety offices of around 20 major companies (both contractors and operating companies) and institutions. These interviews provided information about details in the design process, differences in the design organisation and about which risk and safety analysis procedures the company utilised. Some design errors call for new checklists or methods aimed for instance at covering the three-dimensional piping arrangements, maintenance and repair, and situations where chemicals and operators come into contact. The emphasis on safety analysis methods shows a surprising variation between different companies, and about half of the companies have integrated a hazard and operability study in the design process. Variation was also found in relation to safety policies, and not all the companies had one. The recommendations made are to integrate hazard and operability study and action error analysis (safety analysis procedure aimed at the procedures) into the design process. Further research is needed to develop and test a proposed piping safety analysis (PISA), which is to be applied when the piping arrangements have been made.
