Hazard Risk Assessment

Add to reading list

Technica was a new company of consulting scientists and engineers, specialised in safety analysis and the technical risk assessment of major hazards in the oil and chemical industries. It was set up by four colleagues and myself in 1981 to advance the new science of technical risk assessment of hazards.  

See Technica brochures from 1981 and 1983 here & here

Our team at Technica was innovative and successful, growing fast and becoming the European market leader in this subject area within three years. I left Technica in 1985 (to join Shell International). Technica was later bought by the Norwegian company Det Norske Veritas.
