Brian Tyler

Brian Tyler established his consulting company with his colleague Bob Simmons in 1990. At that time he was also on the staff of the chemistry department at the University of Manchester Institute of Science and Technology (UMIST). His research work at that time focused on the areas of fire, explosion, self-heating and kinetics, including work on industrially related problems. By 1990 he had over 20 years’ experience of organising meetings and courses under the general heading ‘Safety in the Chemical Industry’. These included HAZOP and HAZAN, Fire and Explosion, Accident Investigation, Gas Dispersion and many others. His course “HAZOP study for team leaders and team members" is still run by the IChemE under the leadership of Phil Aspinall. Another major activity has been the authorship to two IChemE monographs. The first, written with Frank Crawley and Malcolm Preston, is ‘HAZOP, Guide to Best Practice’; the second with Frank Crawley is ‘Hazard Identification Methods’. In 2011 he was one of the first group elected to the newly established class of Associate Fellow of the Institution of Chemical Engineers.Physical chemist. Cambridge University and UMIST. Research into gas phase processes and explosions including self-heating of solids and gases. Organiser of the Safety in the Chemical Industry postgraduate courses held at UMIST from 1969 to 1990, especially covering HAZOP and HAZAN. With S&T Consultants from 1990-2015 delivering training courses on HAZOP and other safety methods within the UK and overseas. Co-author of the IChemE books: HAZOP: Guide to best practice and Hazard Identification Methods.
