As most of you know, PRCS Entry is one of the specific SWPs called out in the PSM and RMP standards. But many programs fail to meet 1910.146(f)(4), and a recent CSB accident report tied the requirement for canceling a permit to a catastrophic explosion event. 1910.119(f)(4) The employer shall develop and implement safe work […]
NTSB’s historical investigations into major gas and hazardous liquid pipeline ruptures continue to shape current rulemaking tracking. PHMSA has been actively reviewing the established Potential Impact Radius (PIR) calculation methodologies used in integrity management programs. The review aims to determine whether current mathematical models accurately account for human response data, rapid-ignition variables, and modern accident
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.

We have another tragic example of how dangerous hot work is on used (even new) containers when proper precautions are not taken. This event seriously injured the three (3) workers in Ankara, Turkey, in February 2024. Members can download the video from the video library.
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 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,
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
What is a management system (40 CFR §68.15(a))? How comprehensive must it be? Is there a standard format?
