Might be a stupid question, but is wearing shorts allowed in chemistry practicals? (Doing chem2 over summer)
I mean in Semester 1 last year I wore shorts in the pracs, and one prac I spilled a few drops of 2M HCl on my bare skin. I went to the people in charge of the entire first year lab (it was stinging and painful) and they got wet paper towels to wipe it off until it was no longer stinging (only a few drops so). While there they were debating with themselves whether long pants or shorts would have been better. Long pants means a layer of protection before the skin, but if it gets wet with chemicals it's much harder to get out, so the bad chemicals stay against your skin for longer, but shorts mean it's easier to clean up, but easier to get spilt on in the first place? They hadn't reached a consensus, though, but it's been food for thought for me all year since.
So yeah, TLDR, wearing shorts in chem pracs is allowed. Good luck!
