Re: Chem Store Usage

You could go to your OHS Committee. Or phone Dr Pam Veivers at PSA (if you are a member) But I feel sure they will help you any way. On 02 9290 1555. Pam will know what the legal bits are.

Do hope this helps

Re: 2007 Chemical Safety in Schools Update Course

From what I believe, CSIS training is done as a whole school project, once you have been signed off. That is it, until a main change happens. Each school should done a CSIS training first day back for new staff (New to the school). Mostly it is the head of Science that does the training, which of co...

Re: risk assessment

"Getting it to work" It came out in 1995. "Further copies are available through Erudition at a cost of $30 each, please remember that was 1995. It a small book only 57 pages. It was developed by NSW, but I am sure other states would have one just like it.

Hope this helps

Re: risk assessment

To get started on your SOP's, you could use "Getting it to work" Physics equipment for High Schools, put out by the DET. We copied these to put them with the equipment, so any teacher will know how to use that piece of equipment.

It is very expensive to make up 1M of copper sulfat...
