Chemical Process Safety (PSM/RMP)

The story of the Three (3) little MI failures and the COVID Pandemic

At 12:30 am on May 30th, 2020, failure of a 6” pressure piping elbow located on top of a storage tank resulted in black liquor being sprayed onto adjacent buildings, equipment, and ground within an approximately 50m (165′) area. The line from the liquor transfer pump into the top of the tank failed and 74%…...

Under CFATS, a chemical facility is “any establishment that possesses or plans to possess…...

Is an MOC required when making repairs to an ASME pressure vessel?

This is another case where OSHA and EPA compliance may be the least of our concerns, as this is REAL LIFE process safety – NOT compliance work!  Yes, we have to comply with our repair RAGAGEP; but I was referring to whether a facility does a MOC or not.  Let’s examine this type of work…...

Are Mechanical Controls Considered Administrative Controls? (EPA RMP)

Although I agree with most of EPA’s FAQs regarding their RMP standard, this one is just sad!  The question was asked… Are Mechanical Controls Considered Administrative Controls? EPA and I could not be further apart on this topic, as EPA actually stated they would NOT accept an engineered hi-level alarm/interlock and would only accept a…...

Is a hazard review synonymous with a process hazard analysis (PHA)?

The prevention program requirements under 40 CFR Part 68, Subparts C and D, include “hazard reviews” and “process hazard analyses”. Is a “hazard review” synonymous with a “process hazard analysis” (PHA)? No, and here is the difference…… Membership Required You must be a member to access this content.View Membership LevelsAlready a member? Log in here...

Do I have to conduct PSM/RMP incident investigations of releases resulting from theft?

If an incident caused by theft or other criminal activity at a covered facility resulted in or could reasonably have resulted in a catastrophic release of a regulated substance, then the owner or operator of the covered facility must perform an incident investigation. If it would be unreasonable, based on the owner/operator’s knowledge of the…...

What if the quantity in the process fluctuates?

One of the top questions we get and it goes to HAZARDOUS MATERIALS MANAGEMENT!  We have an EHS/HHC on site and today we are under the PSM and RMP TQ’s – KEEPING in mind that the standards have different TQ’s for many of the EHS/HHC’s.  But if we do not manage these inventories AND cap…...

EPA finally makes it clear – the TQ determination is NOT based on the capacity of the vessel(s)

I have had seen dozens of facilities covering (albeit very poorly) a process that is NOT a PSM/RMP covered process because some consultant told them it was.  The consultant(s) would point to an old statement by EPA that the Threshold Quantity (TQ) determination was based on the process’s ability to hold an amount exceeding the…...

How far apart do separate vessels have to be to be considered different processes?

EPA attempts to define and quantify how far apart separate vessels have to be to be considered different processes. There is no hard-and-fast rule for how great this distance should be before you can consider the vessels as part of one process….

Your PSM written program should not be a cut and paste of the standard(s)

Yes, I’m well aware that EPA has officially stated that an Org Chart showing who is responsible for the various elements is all that is need to “comply”.  But in an actual functioning process safety management system, we will not only define who is responsible for each element but we will also explain HOW each…...
