Would I use the biohazard or toxic symbol for Copper Sulfate?

Question

I'm writing a small warning note in a lab procedure, and I was wondering if I could put the biohazard symbol next to the warning (since it is toxic if ingested, and it's a skin and eye irritant), or if I have to use the toxic symbol, which is a skull. (I would much rather use the biohazard symbol, but If I should use the toxic symbol then I will).

If I can use the biohazard symbol, should I have it be in a yellow triangle or a red box? (I know either way works, but which one is more commonly seen with chemicals like copper sulfate?)

Could I just use the warning sign (triangle with an exclamation mark in it)?
I just think the lab might look a bit...informal with a small skull next to a types up procedure.

Answer 1

Use the toxic symbol. Good ole' copper sulfate has been used for killing unliked stuff in swimming pool water in ancient times. It is toxic. Not a bio-hazard. But, it is not as poisonous as say, chlorine, or iodine. In a school chem lab, I think just a triangular warning sign would be appropriate. Keep the really scary signs for really scary stuff so people don't start to disregard them.
