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

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.

I had one stuck tight too. I heated the ring then put an ice cube on the ball. Released by the second cube.

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.

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.

SDS (was MSDS) have to be updated every 5 years.

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?

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?

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 He replied that CSIS is 17 years old and now out of date and RiskAssess is current knowledge.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 ...

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.

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.

We only use calcium and sodium. Have never had lithium and potassium is banned in DEC schools.

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...

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...

Ours were collected with the chemical pick-up.

I have two of them. I took one to Newcastle TAFE but no-one had any ideas there either.

Has anyone tried acrylic burettes?

Does Phillip Crisp write CSIS? I thought it was a department group that was responsible for this.

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?

I've got 2x3ft tanks - one with water plants for the fish and yabbie, and the other for a succulent garden.
