ASME PCC-1 TIGHTENING PROCEDURE – Pressure Boundary Bolted Flange Joint Assembly

Sweating the “small stuff” matters in process safety management.  Meeting the details of our chosen RAGAGEPs matters!  Although I am often told, “That is a picky audit finding,” it is what it is.  Far too many facilities believe that designing their process piping to be bolted flange assembly vs. welded joints is somehow easier; in…...

Flanged piping… Torque matters (at least it does to OSHA)

We have discussed the critical role of “torque” in constructing our chemical processes.  I catch a lot of flack for my insistence on this critical function, for which I am genuinely surprised.  But our piping design and construction RAGAGEP (ASME B31.3) is pretty clear on the matter, and now OSHA and EPA have “caught on”…...

Catastrophic and FATAL failure of 12″ (25′ long) pipe during pressure test

Another pressuring test “gone bad”.  I want to remind anyone who wonders how to DEFINE and QUANTIFY a “safe distance” when piping is being pressure tested, especially when that test is a “pneumatic” test.  ASME PCC-2–2022, Repair of Pressure Equipment and Piping, Mandatory Appendix, 501-III, Safe Distance Calculations for Pneumatic Pressure Test is an EXCELLENT resource to…...

A look at the real costs behind a catastrophic chemical release (Chlorine)

On August 27, 2016, at about 8:26 a.m., a railroad tank car sustained a 42-inch long crack in its tank shell shortly after being loaded with 178,400 pounds of liquefied compressed chlorine at the Axiall Corporation Natrium plant in New Martinsville, West Virginia. Over the next 2.5 hours, the entire 178,400-pound chlorine load was released,…...

What do you have connected to your emergency back-up power source(s)?

I think most businesses are familiar with “backup power” sources, from battery packs on exit signs and egress lighting to UPSs on servers for their IT needs. But for facilities that store, handle, and process hazardous materials AND with safety systems associated with the storage, handling, and processing of those HAZMATs, there are some additional…...

NFPA 497 updates the electrical classification (HAZLOC) around PRVs

NFPA 497 has added TWO (2) NEW figures to establish classification areas around Pressure Relief Valve (PRV) vents.  The classification areas of the sources in several figures in Section 5.11 have been removed to eliminate confusion.  This change is significant in two (2) ways:… Membership Required You must be a member to access this content.View...

Difference between the “Work Permit” content and “Training” content

The Hot Work Permit element of both OSHA’s PSM standard and EPA’s Risk Management Plan is one of the shortest elements’ of the 14 elements.  Its presence is to require a written permit to be issued when performing Hot Work in/on/adjacent to a covered process.  Some may not fully understand the need for this element,…...
