Goggles for the eyes, gloves for the hands, and an apron/lab coat. I prefer the lab coat. long sleeves if you are prone to splashing, but fitted clothes. not loose ones that can catch fire. same with long hair: tie it back.
Bunsen burners. Fire. long flammable hair. Bad idea. Harsh chemicals. delicate hair.Bad idea. You may not look amazing with your hair tied back but its potentially dangerous. The teachers may seem strict but if your hair goes on fire and they haven't told you to tie it back then they could get in trouble.
goggles and cover your hair. also closed toed shoes are a good one.
