With all the recent changes in the Process Safety community within the USA, I have been getting a lot of questions regarding pressure vessels and what to expect when it comes to how they play a role in PSM/RMP programs. These vessels pose our greatest risk within our process as they contain the majority of our HHCs/EHSs. Now I am not saying that these vessel’s failing is a “high risk” because Risk is both probability and severity; however, if these vessels are not operated properly nor cared for properly, the risk of their failure is increased. In this article, I hope to break the ice for many who have never been through a pressure vessel inspection.
