At approximately 9:45 p.m. on November 4, 2003, a maintenance employee went to the chlorine house to turn on the chlorination system. The chlorine house measured 3 feet, 10-inches wide by 5 feet, 10-inches long and was approximately 10-feet high. The water lines ran through a hole in the block wall. The hole in the block wall lead directly from the chlorine house into the chemical room. The hole was...

I have upload my REVISED Car Seal Program and the PowerPoint that goes with it to the Document Library – Chemical Process Safety folder.

One of the things I look for in my PSSR walk downs is “short-threading”. I was raised with the old pipe-fitters rule of “three threads showing”; however, ASME now accepts “full engagement” as bolt flush with nut. Some companies will have a QA/QC requirement of 1-thread showing. So I have to accept the ASME definition of “full engagement”, but I can almost...

I just uploaded my newest version of the SAFTENG Car Seal Program that reflects the code requirements in 2025. A client has learned they need to car seal some valves that are “intervening valves” after a PRD and before a header. The OEM commissioning the process stated they had a Car Seal Program and would “handle it”. This is what we found… Do you see it? … HomeRead...

The last few weeks I have been sharing passages from Dr. Todd Conklin’s books. And I could not agree more with 99% of what he teaches. This week is one of those 1%’ers… I believe that a GREAT Safety Management System (SMS) will in fact help organizations “learn” from accidents. Starting with a well established incident management system that includes a robust causal analysis...

With the recent catastrophic and fatal pressure vessel (PV) failure in KY, I have to speak up and point out a very dangerous and unfortunately common failure we see in our work. Far too often we visit a facility under the guise of doing process safety work and we typically find the PSM covered PVs and their PRDs are in a MI program. However, in the same room we can find PVs and their PRDs that are...

Fundamentally, employers and employees must be alert to the fact that working with a “closed system” does not always ensure safety. Operations involving the opening of valves or pumps on otherwise closed systems or working on such equipment that is not isolated or locked/tagged out are particular sources of danger. When a normally closed system is opened, the potential exists for releasing...

At 8:04 a.m. on May 11, 2023, an employee, 58, working for an oil and gas support services company was found dead. On 5/10/23, the night before, the employee had instructed his coworkers from other contractors to go home, and he would finish the job up. This was the last time anyone had spoken to the employee until he was found deceased. The employee had been pressure testing a pipe with nitrogen....

At 10:20 a.m. on August 1, 2024, an employee, 53, was working inside a transformer. The employee entered a permitted confined space filled with nitrogen and asphyxiated due to overexposure to nitrogen. The employee was killed. … HomeRead More »
