Re: Another GHS question...
I thought that the dangerous goods diamonds stayed (black outline) and the new GHS diamonds (red outline) were added.

Re: Placarding on Buildings
Our local fire brigade receive a copy of our chemical register and a map of the school with the stores marked so they know where the chemicals are stored and what is stored there.

Re: beam balances.
Ours are used every year for year 7 - Working as a Scientist and then they are used periodically throughout the year. We also use them for the year 9 practical assessment weighing tasks and have a digital balance at another station as well.

Re: Biuret Solution
In the CSIS appendix B Biuret solution is orange dot - years 11-12. Toxic if ingested. Corrosive due to the presence of the sodium hydroxide (6M); avoid skin contact.
For junior school we use 0.1M copper sulfate and 1M sodium hydroxide - green dot.

Re: Glassware in labs?
I was just listening to Alan Smith on the DEC Webinar about the new CSIS package. He stated 'If you don't have perspex glassware to replace soda glass you are running a risk'
Does anyone have perspex test tubes that they use consistently?

Re: Bromine water
Hi Labbie
Appendix B has bromine as a teacher only chemical and instructions on opening an ampoule (cool first). I still have 2 ampoules left and intended on using them up. Where does it say we are not allowed to have them any more?

Re: Is borax really a teacher only chemical?
I contacted Phillip Crisp about lead nitrate. RiskAssess has it as teacher use only for 0.1M. CSIS has it as years 7-12. He replied that CSIS is 17 years old and now out of date and RiskAssess is current knowledge. We still use RiskAssess to do our experiments but when something is different - like ...

Re: risk assess tips or tricks
I don't make changes to the teacher's risk assessment but if they have left off items - particularly minor equipment - then I add it using 'add review notes' so the next time someone wants to use the RA they can add these things in the right place.

Re: risk assess tips or tricks
Teachers have to write them because they are assessing the risk to the students in their class. This might change depending if the class is a top class or a bottom class.

Re: Neutralising Chemicals
Add universal indicator to the solution to be neutralised. See what the pH is. If the solution is an acid with a low pH (1-6) add an alkali to make the pH 7 and if it's a base (pH 8-13) add some acid to make it pH 7 For example, 0.1M HCl solution pH about 1. Add universal indicator. Add NaOH until t...

Re: labeling old chemicals in store
It seems that everything is as clear as mud. I chair our WHS Committee and I can't get answers from anyone. Our WHS consultant just passed on the information that: 'You keep doing what you have been doing until directed by the Department and the new CSIS is delivered.' I can't see how we can be held...

Re: Risk Assess and labels
RiskAssess has moved over to GHS and they look good. One of my teachers did a risk assessment for lead (II) nitrate and it has come up with the 0.03-0.18 M (1-6% wt/wt) as a teacher use only. CSIS still has it as 7-12 years. Has anyone else found anything different since the changeover?
