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.

Is your life-safety equipment ‘fit for purpose’?

Life-safety, firefighting and critical emergency systems depend on the unfailing reliability of electric cables during a fire. Should these essential cable systems fail, the critical equipment they supply also fails, putting occupants, emergency responders and property at risk.  A fragmented…

British standards for fire testing of electric cables are falling behind

Almost all Life Safety & Fire Fighting systems depend on the reliable function of electric cables during emergency. If these essential cables fail during a fire event, the critical equipment they enable also fails. This could mean that firemen’s lifts,…
