Re: Was there an official memo about GHS ?
We have been upgrading since we heard about GHS at the ASET conference quite a few years ago - it takes time to do it, while still keeping up with prac work. All our chemicals drop bottles etc are GHS now, and I have just completed the Hazard register for the whole school - GHS compliant

Re: Ball and Ring Set

Re: storage of H2O2
I have heard it is not safe to store in fridge - but we do. I think the lower concentrations that we use -6% - is quite safe in there.
No fridge is sealed completely perfectly so any gas release would not build up in the fridge.

Re: What are you doing this Holidays
Moree is about 1 hr 20 minutes drive from Mungindi - if you are not a local.. I wont tell you the time it takes for locals to do the trip! The railway used to go all the way into Mungindi but the station was washed away in a flood and never replaced which is a shame..

I was planning on retiring there because I can rent a house at low rental and afford to live on the pension, but a house is on sale at a little above the value of all my superannuation - so hoping ...

Re: cleaning pipette,burette and filler bulb
It depends on what they have been used for. Mostly you can rinse well in clean water then final rinse with distilled water. If I need to, I soak in detergent and water then rinse. The bulbs are tricky. You can fill them up with water and push the water out a few times to rinse all the valves, then s...

Re: Dry Ice SDS
Cargo van - NO GO, station wagon - NO GO the reason is for the drivers safety - Dry ice is made of CO2 and when it "melts", it becomes CO2 gas straight away without leaving any wet mark (that is why it is called dry ice). CO2 is easier to be tied up in our blood and thus, when the dry ice ...

Re: RECALL PORTABLE GAS COOKERS
I was using them in rooms that did not have gas connected.. I have now had to buy the portable bunsen burners as you have agregory - and they work well, then I had to buy the taller tripods to go over them!
