I am trapped...

One one hand, I can get many types of chemistry, as I work at a school..

On the other hand, I am not allowed to use it if I havn't gor a safety sheet, written in Danish, put in a map! No matter what chemistry!

So in fact I am not allowed to teach developing in Caffenol, as I can't get a safety sheet on coffee!!! or C vitamine...
Crazy world!

Solution: I do it anyway...
