I have Calcium carbonate powder and marble chips . Chemwatch seems to also want to lump the two as calcium carbonate . CSIS has ...

Re: asbestos mats

This is an old topic but I wonder if any new info has come to light . Last week at my other school , the HT asked me to collect all of the heat mats and dispose of them as she was convinced they were asbestos. They look exactly the same as the ones we use at this school so I bought them here . Head ...

Re: Storing Chemicals in the prep room

Thanks. You all made sense. Might have to re-evaluate a few things .

A query about Phenolthalien Droppers , as this is basically all alcohol , then should they definitely need to be stored in the Flammables cupboard .

Storing Chemicals in the prep room

Recently I watched a DVD called working in science .( circa 2008) In one segment , the labbie was showing her prep room . She said she had all her chemicals in special storage groups just like she did in her Chem store room. I've been reading back through all the forums here trying to establish if a...

Re: New safety directions with dissection gear

Only thing I can think of is to minimize the risk of infection should a kid cut or stab themselves before they are presented with a tray of gore to cut up....gosh I wonder if the Metal work and woodwork rooms will have to sterilize the saws and chisels next #-o

Re: GHS Labeling

Personally I don't think the Riskassess labels satisfy the legal requirements according to that document, for original containers anyway. They may be ok for small containers going into the classrooms but the original container must include safety and first aid. It also must have manufacture / suppl...

Re: GHS Labeling

RiskAssess GHS labelling much easier to use than Chemwatch; just enter chemical name, choose label size (choice of 4), choose solid or solution; if the latter, enter molarity then download and print. Sounds great xenon. Would love to see some samples of the new labels. Curious though about not bein...
