In today’s workplaces, it’s hard to find a large business that does not require Hi-Vis Vest/Workwear. What is not hard to find is a business with HAZLOCs where workers are required to wear FRC but are wearing nylon Hi-Vis vests OVER their FRC. I am all for making workers more visible to powered industrial trucks…...
I took these pics for those who may have never seen a FAILED leak test using a “bubble solution”. We have discussed the “sensitivity testing” using the bubble test method many times, as it’s the most common method. I have been using the brand SNOOP my entire career and highly recommend it.

Many may be familiar with “flange jumpers,” or some may call them “bonding jumpers,” that are used to ensure a continuity to ground across a flange with gaskets that act as “insulators”, such as PTFE gaskets. During a recent walkdown of a flammable liquids process, I came across this “jumper”. Design called for “jumpers” on…...
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 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…...
