This month marks the 20th anniversary of OSHA’s Process Safety Management standard, which is built upon Recognized and Generally Accepted Engineering Practices (RAGAGEP). There was no way OSHA could write a “specific” standard to cover all the types of processes handling the list of Highly Hazardous Chemicals (HHC) so they instead wrote what is called a “performance oriented standard” that is VERY OPEN and flexible so that an employer can best decided how to run their process safely. The intention was that the employer would adopt published RAGAGEPs to design, build, operate and maintain their highly hazardous process.
