Re: riskassess

I've heard really good things about this program. However, our HT is reluctant to use it as he is worried that teachers will just "tick the box" for the prac they are doing and not give any thought to the risks involved, whereas if they have to write something out they will give more thoug...

Re: Lab Tech Needed for 11 days

If I didn't try and laugh about it, I'd get really angry!
(Maybe I should start new post elsewhere so I can continue to laugh about it!)

Re: Potassium Bisulfate

I'm with Labbie. If you don't need it, get rid of it, especially given what has happened to the bottles. And, it's a bonus it can be disposed of in the rubbish because, no one needs to know and no one will notice it missing!

Re: chem gold 3 program

I'm at a loss as to what they are getting at with the average volume/weight. Instead I put in the maximum quantity we are likely to have. This is usually what Workcover requires, the thinking is that it is no point putting in what you have today, then tomorrow you go and buy more, so you're essentia...

Re: microscopes

Redbank are in Picton on Henry Street. We use Broken Bay Communications which is run by a retired science teacher. He will service microscopes, as well as repair any equipment. He charged us $465 last time, but was here for a day - cleaned and serviced about 36 microscopes and repaired two skeletons...

Re: Safety training for teachers

Kathryn I'd look at proper storage of chemicals/hazardous substances. Encourage them to consider what they have in their class rooms and do they need these things. For example, one staff room had Zero weedspray, I don't know why, but they have now given it to the property department. Go through the ...

Re: Chemwatch for Independent schools

Why do they have to be so pedantic?? I think this comes from there being so many products available (not just chemicals for labs), each having it's own formulation that to deal with the majority, Workcover require a specific MSDS for each product. In their Code of Practice for Control of Workplace ...

Re: Chemwatch for Independent schools

We use ChemFFX too. Just when I started to work out the old one, they changed it! I'm concerned about the safety data sheets they supply, are they from the correct people? For the current legislation, Workcover clearly state that safety data sheets from a third party are not acceptable. I can't imag...

Re: DISHWASHER

We just got an LG dishwasher. I'm still getting used to it, I don't think it fits as much in as the old Dishlex, but the new one doesn't leak everytime I use it, and the glassware actually looks sparkly clean - it really was "time to go". We bought a new fridge and microwave at the same ti...

Re: GHS

Jazz
Thanks for sharing this momentous experience with us all!
How did you merge the green dot into these labels? When you print them, do you just print them onto normal paper? Or do you have some other amazing skills???

Thanks for your help

Re: Calcium Oxide Classification

Linotas - good to know I'm not alone in this. When you look at a full MSDS that is 10 pages which Workcover want us to have, and then look at the mini MSDS that is only one page you can easily see why Workcover doesn't accept them - they are not in the standard form. The one advantage chemwatch has ...

Re: Calcium Oxide Classification

Hi Rae (and everyone else!) I feel like I'm opening a can of worms when I start looking in the chemical store. Going through the list yesterday, I found 5 chemicals incorrectly stored in the stable chemicals section that should have been elsewhere, some were wrong according to the MSDS that was prin...

Calcium Oxide Classification

Our Calcium Oxide is stored with the other corrosives (non-acids), it has a DG 8 label on it. I was just looking on Chemwatch and it has no dangerous goods code on the mini msds at all. When I looked at the supplier's website it is classed as a DG8. Thought it was something for you all to be aware o...

Re: Sulfamic Acid

Thanks, couldn't find it on Serrata's website, probably mispelt it. Seems that sometimes it is spelt with an "f" and sometimes "ph". I can give you the "recipe", but I've found some of the chemicals are expensive eg malonic acid is $98 for 100g. The kit cost $19 from Pr...

Sulfamic Acid

We bought a kit for Briggs-Rauscher Oscillating Reaction. It is made up of sulfamic acid, potassium iodate, malonic acid and manganese sulfate. It is quite fun to do - cycles from pale orange to dark purple and back again. We want to buy the individual chemicals but I cannot find any supplier of sul...
