The risk based approach to inspection of industrial plant is now an accepted practice. It is possible to determine and monitor consistently the mechanical integrity of industrial plant, or other such engineering assets, by using risk based methodologies. This guide has been written by industry to enable use of risk-based inspection (RBI) to its best effect. EEMUA 206 has been developed with assistance from the GB Health & Safety Executive and will help businesses to interpret and use the HSE Report 'Best Practice for Risk Based Inspection as a Part of Plant Integrity Management'.
