Andy Brazier has a Chemical Engineering degree from Loughborough University (1986-1990). He obtained a PhD in 1996 on the subject of Human Factors in the Process Industry, and was lucky enough to have Trevor Kletz act as his external for this. Andy has over 20 years of consultancy experience in the process industries with particular expertise in human factors and process safety. He has written research reports for the UK Health and Safety Executive, presented at multiple conference including IChemE Hazards and had a number of articles published in the Loss Prevention Bulletin. Andy is a Chartered Member of the Institute of Ergonomics and Human Factors and Associate member of the Institute of Chemical Engineers. David Edwards is a chartered chemical engineer with 30 years of experience in Safety, Health and Environmental (SHE) matters. He worked on Inherently Safer Design (ISrD) with Trevor Kletz and others at Loughborough University, where he wrote one of the seminal papers in the field, ‘Assessing the inherent safety of chemical process routes: is there a relation between plant costs and inherent safety?’, D.W. Edwards and D. Lawrence, Process Safety and Environmental Protection (PSEP), 71, 252-258 (November, 1993), which has been cited more than 150 times. He won the IChemE Hutchison medal for ‘Inherently Safer Design – Present and Future’, J.P. Gupta, D.W. Edwards, PSEP, 80, B, 115-125, (2002). He is an authority on Inherently Safer Design, which he has championed during his oil and gas facility design work with Granherne / KBR Fiona Macleod studied Chemical Engineering at Cambridge University (Selwyn College 1979-1983) before joining ICI as a graduate trainee. She has worked in the International Chemical industry for over 35 years in manufacturing, design and construction, engineering and maintenance, demolition, technology transfer, sales and senior management. Her experience with process safety was gained at the sharp end, practical experience of managing high hazard chemical sites. Craig Skinner studied Chemical Engineering at Loughborough University and has nearly 30 years of international experience at BP working in refining, petrochemicals, upstream and low carbon energy. His roles have included process safety technical authority, operational safety leadership, technical and engineering management and human performance on projects and operating plants in the UK, Asia and the US, including corporate safety leadership. Ivan Vince is a Chartered Chemist and Chartered Chemical Engineer with 40 years' experience in fields related to process safety, beginning with postdoctoral research at Imperial College involving flammability limits. He has taught postgraduate modules on risk assessment at several universities in the UK and abroad, given expert evidence at nine Public Inquiries and participated in the investigation of several major accidents, including Buncefield. Publications include Vince I (ed) (2008) Major accidents to the environment – a practical guide to the Seveso II Directive and the COMAH regulations (Oxford: Elsevier) ISBN: 978-0-7506-8389-0.; Vince I (2013) Explosion at a hazardous waste site caused by contaminated nitric acid, Chemical Engineering Transactions 31, 535.; Vince I (2011) Societal risk in land use planning – the scale of ‘scale aversion’, Hazards XXII, Symposium Series No.156, 408-410 (Rugby: IChemE).
