We have discussed the critical role of “torque” in constructing our chemical processes. I catch a lot of flack for my insistence on this critical function, for which I am genuinely surprised. But our piping design and construction RAGAGEP (ASME B31.3) is pretty clear on the matter, and now OSHA and EPA have “caught on”…...
The refrigerant in this accident is R-32 (Difluoromethane), described as ” a colorless, odorless, mildly flammable gas. “Its ASHRAE rating is A2L, making it a CAT1B flammable gas if OSHA adopts Rev. 7 of the GHS this year. These A2L “mildly flammable gases” are exempt from many of the requirements other flammable gases must meet…...
Another pressuring test “gone bad”. I want to remind anyone who wonders how to DEFINE and QUANTIFY a “safe distance” when piping is being pressure tested, especially when that test is a “pneumatic” test. ASME PCC-2–2022, Repair of Pressure Equipment and Piping, Mandatory Appendix, 501-III, Safe Distance Calculations for Pneumatic Pressure Test is an EXCELLENT resource to…...
One of the most critical fundamentals of Occupational Safety and Health and Process Safety, yet it is wildly unknown and rarely used in most workplaces we visit. Still, in the 21st century, we find employers handing out PPE like candy on Halloween without understanding the limitations of that PPE and even if the PPE protection…...
I may be biased, but you would be hard-pressed to find a bigger fan and believer in TapRoot®. I love TapRoot®, but I reserve it for significant incidents. 5-Why’s is an excellent tool for less mature safety management systems (SMS). As I like to say, don’t blame the tool – look to the user for…...
On August 27, 2016, at about 8:26 a.m., a railroad tank car sustained a 42-inch long crack in its tank shell shortly after being loaded with 178,400 pounds of liquefied compressed chlorine at the Axiall Corporation Natrium plant in New Martinsville, West Virginia. Over the next 2.5 hours, the entire 178,400-pound chlorine load was released,…...
As I prepare to implement a Behavior-Based Observation Process (BBOP) for a client, I am dusting off some of my old training content and postings. I had used this material since 1994 when I implemented Actively Caring as my first BBOP, and it is still my favorite model today. Although we have blended some other…...
Some years ago, a colleague asked me to help coach a management team at one of her locations that was trying hard in safety, but she feared they were going down a path that we had experienced decades earlier when we worked together; her as a Chem Ops unit manager and me as the site…...
I think most businesses are familiar with “backup power” sources, from battery packs on exit signs and egress lighting to UPSs on servers for their IT needs. But for facilities that store, handle, and process hazardous materials AND with safety systems associated with the storage, handling, and processing of those HAZMATs, there are some additional…...
Information regarding OSHA Minor Servicing while working in General Industry. The OSHA standard states: 1910.147(a)(2)(ii)(B)An employee is required to place any part of their body into an area on a machine or piece of equipment where work is performed upon the material being processed (point of operation) or where an associated danger zone exists during…...
NFPA 497 has added TWO (2) NEW figures to establish classification areas around Pressure Relief Valve (PRV) vents. The classification areas of the sources in several figures in Section 5.11 have been removed to eliminate confusion. This change is significant in two (2) ways:… Membership Required You must be a member to access this content.View...
