Re: labeling old chemicals in store
Mmmmm well I've been told by my principal that he wants me to do the whole school
So to clarify Labbie, it only needs a label if it goes into a classroom?

Re: labeling old chemicals in store
Do we have to put GHS labels on EVERYTHING?
For example, paraffin oil, agar, aluminium oxide, barium sulphate, etc etc etc,
when looked up in Chemwatch the label has absolutely no information on it?
