The arrangement below is very common in processes/systems. This simple yet common arrangement causes havoc in hazard analyses. As the title states, is this arrangement managed with a Temporary SOP, a Car-Seal, or Both? The issue is that the motorized valve is tied to a Hi-Hi level alarm and interlock. When the vessel archives its Hi-Hi level, the interlock CLOSES the motorized valve to STOP flow to...

Several clients design Double Block and Bleed (DB&B) isolation into their process, especially when they know they will regularly enter certain Permit-Required Confined Spaces (PRCS). When these DB&B arrangements are part of the design, the isolation valves and the bleed valve are near one another.

We often encounter an organization that conducts LOTO training annually. They do this because they believe OSHA requires annual LOTO training. However, the standard, 1910.147, does NOT require annual training! The standard requires each authorized employee to be “inspected” annually.

Now the BSEE has shared a SAFETY ALERT regarding a Nitrogen Compressed Gas cylinder that catastrophically failed injuring three (3) workers and causing property damage. The failure...

I think most EHS professionals will agree that bulk tanks of hazardous materials need some means of “secondary containment”. This practice has been in place for my entire career and rarely gets challenged. However, in recent years I have come across several scenarios where either the facility/unit designed the process to function this way or operations have learned how they can operate...
