CDC/NIOSH just answered the question... is LEVEL A needed for a NH3 release?
In my emergency response training around the country it is always an interesting discussion when Anhydrous Ammonia (NH3) comes up and the level of PPE necessary for a “safe response”.  I have always stuck to my 25 years of training that NH3 qualifies for LEVEL A as it meets all the LEVEL A criteria.  However, there are a lot of folks who challenge me on this level of protection...

Refrigerant HFO-1234yf is a PSM HHC with “special or unique hazards” (Part 4)
OSHA’s PSM standard requires Operating Procedures to address “special or unique hazards” 1910.119(f)(1)(iii) Safety and health considerations:…1910.119(f)(1)(iii)(E) Any special or unique hazards. This item is often not necessary with many of the PSM standard’s Highly Hazardous Chemicals; however, HFO-1234yf has a unique property that falls into this requirement. ...

Examples of catastrophic failure of NH3 refrigeration vessels caused by stress corrosion cracking (FMCSA)
Cases of Stress Corrosion Cracking (SCC) in steel vessels using NH3 have been reported by members of the ammonia refrigeration industry. When NH3 is used as a refrigerant, it is kept at -33° C (-28° F). While it was once believed that NH3 SCC)could not occur at such low temperatures, both practical experience and experimental studies have shown otherwise. The Industrial Refrigeration...

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...
