Yes, I am still on this horse! As I discussed last month, there are a number of chemicals that specifically REQUIRE HRVs on liquid piping. Those are chemicals like NH3, Cl2, and LPG, to name the top three (3). But I have recently read a root cause analysis in which a flammable-liquid piping flange leaked,…...
I have written over a dozen posts explaining the code requirements for annual inspection/testing of our chemical hoses. But in the world of PSM/RMP, there is another hose that requires annual inspection and testing… The primary standard requiring fire hose to be service-tested annually is NFPA 1962, Standard for the Care, Use, Inspection, Service Testing,…...
I have been having fun using AI to help me create training images. I love doing LOTO training, and I am always challenged on just how little energy it takes to be “hazardous” and how even 0.1 psig can be lethal.

A couple of years ago, in a PHA, I came across a scenario where a “capture device” had quite “the pull” on several small tanks that were NOT rated for a vacuum. As usual, my inquiry was met with the old “this is the way all the other plants were built and they have not…...

I get it, it’s a 19-second video, and it will probably stir more questions than responses, but this topic is one that needs MUCH discussion. I have made this page FREE for anyone who wishes to chime in. A couple of items to consider: So what say you? We can discuss this in the comments…...
Establishing a Double Block and Bleed (DB&B) positive isolation is a critical safety protocol when preparing piping and equipment for opening, especially when dealing with Extremely Hazardous Substances (EHS). This process ensures that hazardous materials (HAZMAT) are effectively evacuated and isolated to protect workers from accidental releases. Members can download my .ppt file at bottom…...
As with my NH3 article, I wanted to verify and document the same scenario for scrubbing 1 pound of Cl2 with 50% Sodium Hydroxide (NaOH). Here is what Gemini+ had to say… When Chlorine (Cl2) gas is safely scrubbed with Sodium Hydroxide (NaOH), the reaction produces sodium hypochlorite (bleach), sodium chloride (salt), and water. Bottom…...
