A team-based approach to mechanical integrity implementation



The U.S. Occupational Safety and Health Administration (OSHA) promulgated the Process Safety Management of Highly Hazardous Chemicals standard (29CFR 1910.119) in 1992. One key provision of the regulation calls for a Mechanical Integrity (MI) program to ensure that process equipment containing and controlling highly hazardous chemicals is maintained to high standards, standards which minimize the chances of accidental release and subsequent injuries or incidents. This article addresses the approach taken by Tennessee Eastman Division in the implementation of the OSHA MI requirements.
