Chemical Process Safety (PSM/RMP)

Dutch BLEVE Study (Department of Multi-Scale Physics, Faculty of Applied Sciences Delft University of Technology

While doing some a BLEVE risk assessment I came across this 2007 research paper that I thought was an incredible read.  If you are one who works with BLEVE risk this is a MUST READ; if you’re someone who finds BLEVEs interesting and wants to learn the inner workings of a BLEVE, this paper breaks…...

Process Safety irony of the week

In the past couple of months OSHA has been rescinding LOIs and issuing new LOIs on PSM Retail Exemption and the 1% rule and at the top of these LOIs (posted online) is a “blanket statement” from OSHA that I find sort of humorous and sad at the same time… “OSHA requirements are set by…...

In Part 1 of this series I established how this material is a Category 1 Flammable Gas based on both the manufacturer’s SDS and OSHA’s Hazardous Communications Standard Appendix B.  In this article I wish to address how an HFO-1234yf storage tank, which is an ASME pressure vessel, should be labeled, versus how some have…...
