Risk assess is over the top, so we were told, its really for very very large amounts. Not the amounts used in schools, Again if you are DoE school its the CSIS that you have no choice but to follow. Sorry Bigmack but that is all I know.

Re: Phenolphthalein Agar

Good point Milo, we got a new one for the staff room, so I was able to take the old one just for the prep room. One of the best things we ever did.
