here is an example... SELLEYS POLYGLAZE WASH AND WAX Supplier's MSDS says "not classified as hazardous according to criteria of Safe Work Australia; NONHAZARDOUS SUBSTANCE." Chemwatch says "HAZARDOUS SUBSTANCE. NON-DANGEROUS GOODS. According to NOHSC Criteria, and ADG Code." I ha...

My advice... don't go for the cheapest brand..... see my earlier post where I had carefully worked out how many of each size we should get only to have then all come back basically the same size with only a small difference in length (the medium was bigger than the large!). We sent them back and bou...

Hi Everyone When doing your hazardous materials register, do you go by the manufacturer's MSDS or by Chemwatch? I find that many substances are listed as non-hazardous on the manufacturer's MSDS but are classified hazardous (but with no diamonds) by Chemwatch. In fact chemwatch seems to classify jus...

What do you mean you've used Golden Syrup?? To remove the eggshell? We had 2 eggs in 1M HCL but it didn't work very well, which is why I put the question up. I've now got some in vinegar - hope that works better. Yes they are for the osmosis experiment.

I have the manufacturer's MSDS but it is not very helpful in determining the user group.

The manifest should just transfer ok, it just seems incredibly difficult to actually do anything with it. My user name and password also changed even though they tried to tell me it was the same - (changed from capital to lower case letters)

I have been pulling my hair out over ChemFX. It is exceedingly slow. I can add stuff to my manifest but trying to delete materials is painful. I have been sucessful in getting Vendors MSDS but have no idea of the point of the "short" and "long" gold. Yeah I feel like this as well...

Can anyone tell me the procedure to dissolve an egg shell leaving the membrane intact? I think you use 1M HCl??
Thanks
Kathryn

Its not in CSIS that's why I asked if anyone knew. I don't use it but i have to do the chemical registra and labelling for the whole school - its used by the art dept.

Can anyone tell me the years who are allowed to use liquid latex rubber stuff which is used in the art faculty??

Aldi has anatomy models for sale this week - $6 each. They are small but are made of good quality plastic. One of the teachers asked me to get a few to use as prizes but when he saw them he decided we should keep them. They all come apart eg: the skull is made up of 39 pieces. As well as the skull t...

We have just started using the Risk Assess site so are still getting used to it. It is certainly an easy way to RA's but still have to get the teachers to actually look and sign them. It will be very useful when they get into the habit of doing it before the lesson so i can look up what is required ...

Thanks... so we should be ok to go ahead with the toilet/fingernail expts.
The only problem I have with the CSIS manual is that I am never sure if the info is out-of-date and that the protocols have been superceded - which is why i wanted to check on what others were doing.

Hi I am writing a SWP for Microbiology and have used "Microbiology Safety Considerations" by Hoffman as a reference. However I have a couple of questions...... ...are the protocols she writes officially required in schools? ..specifically she says not to take samples from environments like...

So I finally convinced the powers that be that we need to have at least one full set of lab coats. Spent some time last week looking through catalogues, finding the cheapest and deciding how many we needed of each size - then sent the order away for 30 coats. Was pleasantly surprised when the packag...

so do I need to put my infusion in the incubator rather than just on the bench?
Kathryn

Hi How long can you keep the infusion going? Do you have to add more of anything after the initial set-up, to keep it going for a long time? I'm just starting my first ever hay infusion today.... quite excited ... hope I get lots of critters \:D/ . We have a small creek running through the school so...

Hi Ellice,
Do you work full-time at TIGS? I'm part-time here at Cedars - would like more hours but couldn't manage to do full time somewhere else for only one term.
Kathryn

Thanks Lisa - I discovered that after I had written this question (i"d been trying under chemicals). Still I am surprised that the RA for radioactive sources is surprisingly lacking in specifics in handling, so will be doing a SWP. The risk assess site is an on-line site which does the RA's for...

Hi. Has anyone out their done a RA or SWP for their radioactive sources? We have just subscribed to RiskAssess but they don't seem to have the radioactive sources in their data base.
