Human Factors Engineering in system design: a roadmap for improvement

This paper summarises current industrial practices and standards promoting Human Factors Engineering (HFE) at design stage and revise them with an action research approached based on the concrete case studies performed during a European project called TOSCA. The paper highlights how HFE can significantly impact the costs and risk associated with a plant lifecycle and the current gaps and issues encountered. The gaps identified are used to guide industrial practices and standards towards a more valuable inclusion of Human Factors knowledge in structured system design processes to support human performance and reduce the potential for human errors in operations and maintenance

Remote risk assessment: A case study using SCOPE software

A thorough risk assessment requires input from experts in both safety analyses and the system under analysis. The cost of collecting together the required expertise for a short risk assessment may mean that for some small and medium enterprises (SME), the risk assessment is not deemed worthwhile or is completed using a generic form. This is despite the possible safety and performance benefits that can be identified via a thorough risk assessment. This paper presents a case study of a risk assessment on a rare periodic inspection & maintenance procedure planned by a LPG storage and distribution company in Slovenia. The company identified the need to risk assess this procedure and determine possible safety and performance improvements, including analysis of planned human activities. The expertise for this task was available through contacts spread across Ireland, Italy and Slovenia, but the costs of all the experts gathering together at the site were prohibitive. The solution was the use of SCOPE risk assessment software over internet video conferencing. All participants could share their expertise to identify the hazards and control the risks. This paper presents the method used and explores the requirements and benefits of this approach
