Richard Hosier has over 35 years in the electro-technology industry, working for a variety of tier 1 international electrical cable companies. He consults to EDF on fire performance of cabling systems on the Hinkley Point 2 Nuclear Power Station. In these roles he has extensively researched our changing built environment, particularly in relation to the increasing fire risks arising from higher fire loads in large modern buildings, longer egress times and higher population densities. He currently works as the Director, Buildings and Infrastructure with Marmon IEI, operating in Asia Pacific and Middle East.
