ASME B31.9 covers “utility piping.” The Code DEFINES and QUANTIFIES the phrase “utility piping.” We use this code for utilities associated with our PSM/RMP-covered processes WHEN the utility either PREVENTS, PROTECTS, or MITIGATES an event. Specifically, the code applies to the following services, except as excluded in para. 900.1.3:… Membership Required You must be a...
We have discussed all the requirements for transferring flammable liquids and gases (i.e., NFPA Flammable “4”); however, I have not mentioned the requirements for transferring TOXIC and HIGHLY TOXIC LIQUIDS that have an NFPA 704 Health Rating of 3 or 4. We see these issues in our Chlorine work where Cl2 is a “utility” to…...

During my PHAs and Audits, I typically find businesses that are not focused on the UNLOADING risks associated with their hazardous materials. I tend to get a lot of pushback about how Unloading is a DOT function and somehow not related to process safety. The risks associated with unloading 7,000 gallons of an HHC/EHS through…...
In 2021, I wrote an article regarding OSHA’s Permit-Required Confined Space standard and reclassifying PRCSs to a Non-PRCS status. This article centered on the keyword “potential” when discussing a hazardous atmosphere. The intent of that article (Defining and Quantifying “potential hazardous atmosphere”) was to clarify when/how a POTENTIAL was present to create a Hazardous Atmosphere…....
The question was asked… If the underground piping is protected by a cathodic protection system, does this system need to be turned OFF and Locked Out before workers begin working on the pipe?… Membership Required You must be a member to access this content.View Membership LevelsAlready a member?

One of the more common issues we come across in regards to Hot Work is the encroachment of combustible/flammable hazards within the REQUIRED 35′ Fire Safety Zone. 1910.252(a)(2)(vii) Relocation of combustibles. Where practicable, all combustibles shall be relocated at least 35 feet (10.7 m) from the work site. Where relocation is impracticable, combustibles shall be…...
I normally do not share construction accidents, as I am not a construction safety professional. I would not even attempt to play one on TV! However, this case is an excellent example for the general industry and those who work with hazardous chemicals. One of the reasons why my HAZCOM training is 2+ hours is…...
There are some things I do so that you don’t have to! One of those is scrubbing OSHA citations that are relevant to our workplaces. It is where I get much of my information for my “Line Break Gone Bad” posts, PRCS cases, LOTO, and PSM cases. 99% of the time, I can understand the…...
This video is a great example of two failures: 1) Hazardous Communications and 2) Emergency Response recognition. There is no way he should have walked into the spill, much less into the spray to stop the leak. That was gasoline—NOT diesel; even if it had been diesel, his actions were still out of line. We…...
