Is the Refrigerant HFO-1234yf a BLEVE risk? (Part 3)
As I have written earlier, the new refrigerant HFO-1234yf is a Category 1 Flammable Gas.  This flammable gas is stored under pressure as a liquid, which by definition makes this material a candidate for a BLEVE risk assessment.  For those that are not familiar with the acronym BLEVE, it stands for Boiling Liquid Expanding Vapor Explosion and this week’s “Video of the Week”...

Refrigerant HFO-1234yf and Flame Retardant Clothing (Part 5)
HFO-1234yf is a Category 1 Flammable Gas.  The manufacturers SDS(s) all say it, as well as 1910.1200 Appendix B. PLEASE see my article Refrigerant HFO-1234yf is a Flammable “4” in the NFPA 704 Diamond (Part 2) for the breakdown of these facts.  With this Cat 1 Flammable Gas comes the hazard of flash fire(s)/explosions.  Now there are some who like to say that this material...

BLEVE - Cause and Effect
Crescent City, Illinois propane explosion occurred in June of 1972 when a freight train with numerous propane cars derailed in the town. The resulting explosion leveled approximately half the town.  The water tower in the foreground was over 100 feet tall.  In the past, there have been many deaths and injuries to firefighting personnel as a result of transportation accidents that led to BLEVES...

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 it down and challenges each failure mode (hot vs. cold BLEVE).  During a BLEVE there is...

Cal-OSHA PSM citations @ refinery (Flammables & $566K)
Cal/OSHA today issued 19 citations to a refinery for workplace safety and health violations following an investigation into the February explosion at the company’s Torrance refinery that injured four workers. The proposed penalties total $566,600.  Eighteen of the citations were classified as serious due to a realistic possibility of worker death or serious injury. Six of these serious violations...

EPA RMP citations for "failure to update RMP every five years and §68.15 Management
I have been seeing a lot of RMP citations for failure to UPDATE the facility’s RMP every five (5) years.  By far the number one issue this year based on the ESAs I have been trending.  But one question comes to mind… RMP differs in PSM in a couple of ways, one way being that RMP requires the facility to have a documented “management system to oversee the implementation of...

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 statute, standards and regulations. Our interpretation letters explain these requirements and...

Refrigerant HFO-1234yf is a Flammable "4" in the NFPA 704 Diamond (Part 2)
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 been found labeled.  This article will apply to BOTH NFPA...
