Flammable Liquids

29 CFR 1910.106(d)(2)(iii) specifies the maximum container size depending upon the category of flammable liquid and the type of material from which the container is made.

Lots of folks find it hard to believe when I discuss Minimum Ignition Energy for flammable vapors/gases and Combustible dust. When we get “shocked” by a door handle in the wintertime, and we can feel it, that is around 10-15 mJ. Most common flammable gases and vapors now have MIE’s less than 1.0 mJ. Watch…...

The investigation found that they were processing hand sanitizer bottles by shredding them and separating the plastic from the hand sanitizer. During this process, a spark was created from the machine, which initiated a minor explosion and fire. The business has refuted the fire chief’s official account, saying, “There was no explosion at the site.“…...

Without question, the #1 question we receive regarding Hazardous Locations is… When do I need one?  With flammable liquids (e.g., FP<100F) it is easy to perform the evaluation.  But what if my flammable solution is a CAT 3 or 4 (i.e., Class IIIA or IIIB)?  As the title says, not all flammable solutions require us…...
