Re: mini SDS
Is it a legal requirement within NSW Dept. Schools to have/keep a chemical manifest on chemwatch? I agree it is a pain to use and would much rather create/use my own format. It is not a legal requirement for businesses with small quantities of chemicals on site to have a manifest. They are required...

Re: mini SDS
Rosalie - you're an ex-firefighter!! OMG! That is a surprise. Yep, agree, we are a school with comparatively small quantities of chemicals. Maybe if it was a fire in a chemical factory they may want to check on their way. Bigmack - don't get me on a rant about Chemwatch. So glad I am in a school sys...

Re: Is this Cornflower ?
I thought borax was tetragenic? Mutagenic or something. So it is the long lasting problems, not just the corrosiveness issue.
If I was confident the powder in the bags was only cornflour, I would still throw it out as you don't know if it has been contaminated.

Re: Is this Cornflower ?
There is a process for disposing of unknowns - label it as "unknown chemical" and put it in with your next chemical clean up. There really is no other way.

Re: mini SDS
I can give you NSW legislation, but Queensland is pretty much the same. The legislation is very clear on what needs to be in a SDS and there is also a prescribed format. Mini SDSs do not meet that requirement. The SDS must be produced by the manufacturer or supplier. Chemwatch, which puts together m...

Re: Welcome back to term 2
Yep, we left home on the 7th May last year. Now but a distant memory.
Sadly, it is also nearly a year since my dad passed away.

Re: Welcome back to term 2
Last term was one of the longest eleven weeks of my life! It seemed to drag on for ever and I was so pleased to have two weeks off. This time last year, I was in the final two weeks before heading off on 14 weeks leave, which ended up being five months but that's another story. Nothing as exciting t...

Re: Chemical Storage
For NSW Schools, look on the Safework NSW website for the Code of Practice for Hazardous Chemicals. This details information that you need on a manifest and what you need on a register. For most of us, we only need a register which requires less information. There's also some handy info on labelling...

Re: Chemical Storage
Five metres? Yeah, good luck with that in most school prep rooms/chem stores!
You're right, you work with what you have. Also good to remember, in the grand scheme of things, we are working with small quantities.

Re: Chemical Storage
Segregate according the dangerous goods code is the simplest. Although DGC now only apply to transport, there is no issue with using this system for storage as it clearly states what can and can't be stored together eg oxidisers are to be stored a long way from flammables. Happy for you to PM me and...

Re: Cleaning of Wicks Used in Alkanols prac
Yep - just label the spirit lamps and use the same ones for each chemical each time. I empty the lamps into a labelled bottle like Loopy does, but I put just leave the wicks in the lamps and store in the chem store (which is properly ventilated). Great that you have reached out for help. We are all ...

Re: frozen hearts - help!
Soak them in a bucket with nappysan overnight at least, then throw in the machine. What comes out comes out and what doesn't - depends how fussy your school is.
