EPA and OSHA are getting serious in their RMP enforcement efforts, especially with NH3 refrigeration and refinery piping inspections!

Those that follow my PSM & RMP Citations / Analysis postings most likely have noticed a significant change in the level and depth that EPA and OSHA are conducting their RMP and PSM inspections.  They have cited many more RAGAGEP issues and now dig deep into PHA’s and SOP’s than they ever had before.  This…...

As I always say, we can not discuss MOC and PSSR as if they are separate systems… they go hand in hand 99% of the time.  That is what I want to discuss: how a PSSR requirement defines how we manage our MOC system.  We have discussed many times there are ONLY TWO (2) occasions…...
