This paper reviews the current state of regulations, standards, and technology pertaining to the development and implementation of a material verification program that can assist a facility in preventing and minimizing the release of hazardous chemicals. A universal component identification scheme is proposed to improve how to assess the MI of installed equipment and better understand short-term and long-term corrosion trends. PMI technology, including XRF and OES, is reviewed to help identify the appropriate technology for a given piping system. Finally, three case studies are presented, which highlight the importance of implementing a robust material identification program.
