a. F3 = Finely divided solids, typically less than 75 micrometers (µm) (200 mesh), that pose an elevated risk of forming an ignitable dust cloud, such as finely

divided sulfur, National Electric Code Group E dusts (for example, aluminum, zirconium and titanium) and bisphenol A. F2 = Finely divided solids less than 420 µm (40 mesh) that pose an ordinary risk of forming an ignitable dust cloud.

F—Flammable category. COR—Corrosive. R—Reactive category. UD—Unclassified detonable material. H—Health category. 4D—Class 4 detonable material. W—Special hazard: water reactive. 3D—Class 3 detonable material. OX—Special hazard: oxidizing properties. 3N—Class 3 nondetonable material.
