Thermo Fisher Scientific Inc., Billerica, MA, has announced the rollout of its positive material identification (PMI) seminars across North America. These free one-day seminars cover material inspection for alloy verification, process safety, and API RP 578. “Preventing accidents resulting from the installation of incorrect or out-of-specification metal alloy parts is critical to process safety management in refineries and petrochemical plants. In today’s atmosphere of public scrutiny, it’s essential that petroleum and petrochemical plant inspection personnel discover and correct these material mix-ups before an accident occurs,” said Jim Pasmore, the company’s manager of business development for its Niton analyzers.
