Yes, there are two (2) types of BLEVEs, and much like the myth that BLEVE’s only happen to Pressure Vessels with liquified flammable gases, COLD BELVEs account for nearly 25% of all BLEVEs. So what is the difference between the two? Super GROK explains it better than I could… A BLEVE (Boiling Liquid Expanding Vapor…...

The short answer is NO, but if we do, there’s a significant catch regarding its protection rating. Under OSHA standards (29 CFR 1910.134), you are technically allowed to perform a Qualitative Fit Test (QLFT) on a full-face respirator, but doing so limits its Assigned Protection Factor (APF) to 10. Here is the breakdown of why…...

I was playing around with Google Gemini and wondered about its limitations and accuracy. One of the problems in my HAZMAT courses is showing just how small an amount of Cl2 it takes to achieve an IDLH concentration in a given space. So I asked it.. How many pounds of Chlorine Gas will it take…...
The moral of this story, as we do in Emergency Response, is NEVER to rely on a single data source for critical safety information about the chemicals we work with. In ER, we are REQUIRED to use at least three (3) recognized data sources when developing our response plan and making decisions. SDSs can have…...

Too many safety personnel are not sufficiently familiar with the critical role Vapor Pressure (VP) plays in managing hazardous materials. From our PPE Hazard Assessments, Respiratory Protection, to how we respond to these hazardous materials when there is a LOPC event involving them. But VP also plays a major role in how we DESIGN our…...
A couple of weeks ago, I had a poll in my FB Group asking: Is a personal single-gas detector necessary within our breathing zone when wearing an Air Purifying Respirator in a potential IDLH atmosphere?
