Corrosive material graphic dropping liquid on hand CDL practice app check download check…
That graphic, liquid dripping from a test tube onto a hand and a metal surface, is the corrosive symbol, Class 8. The placard is white on the top half (with that symbol), solid black on the bottom half, and shows an 8. It warns the material can eat through skin and metal.
The corrosion symbol
The Class 8 symbol shows liquid dripping onto a hand and onto a metal bar or surface, with both being eaten away. It is a literal picture of what corrosives do: damage skin and materials on contact.
The placard layout
Class 8 corrosives use a white top half carrying that symbol, a solid black bottom half, and an 8 at the bottom point. The white-over-black split with the corrosion image is the reliable way to spot it.
Do not confuse it with Class 9
Class 9 is also black and white, but it uses black vertical stripes and no symbol. Class 8 has the corrosion symbol and a solid black lower half. Verify details in your official manual.
