NFPA 499, Recommended Practice for the Classification of Combustible Dusts and of Hazardous (Classified) Locations for Electrical Installations in Chemical Process Areas was updated for 2021 and this update involves a very peculiar reference that has me scratching my head.

It’s never a good sign when the EPA inspector is in the process and the operator’s personnel detector goes into alarm and the worried inspector is told… it was typical for the alarm to sound during sampling. This led the inspector to inquire about this level of exposure for a repeated task such as sampling…...
We have discussed this numerous times over the years, but we rarely have a first-hand account of a “bleed” within a DB&B causing an LOPC event.

You walk by a power transmission shaft and notice that it is protruding out and seems to be missing its guard/cap. You look all around for it, as we usually can find them sitting on the floor nearby!!!, but no luck. So you report the “hazard” and issue a work-order to install a guard/cap over…...
I have to first point out that OR-OSHA is a “state plan” ( and my personal favorite!) and is specific to employers in the state of Oregon (OR), but their 2020 LOI on maintaining SDSs electronically points out something that many (including me) have not considered. I have been telling all my clients for decades…...
You may have seen this latest and greatest “detection method” in your junk mail, pop-up ads, or in a search of the internet.

But the organization has another ammonia standard, G-2, Ammonia that is an EXCELLENT compliment to CGA 2.1. The G-2 standard…...
We have discussed the Maximum Allowable Quantity (MAQ) extensively over the years, but a lot of facilities just can’t stay within the confines of a MAQ so what are they to do? Well, it an easy answer but it is not so easy to meet! In this article, I will explain the four (4) H…...
