Bottle of Black Douglas would be lovely lol

I waiting for clarification at the moment. We only just bought a new set in 2021 I don't want to get rid of them and don't see a need to. Our Princple is going into back for us.

Maybe someone new that's freaked out without actually knowing.

Morning Brains trust,

Has anyone else had a directive to dispose of Radioactive Isotopes we only just purchased new ones in 2021. Any input would be greatly appreciated.

lol I heat my lunch in ours

I would get your school to invest in a pressure cooker. We put them in an oven bag then pressure cooker on high for 15 mins. They really should be destroyed under heat and pressure. Then they can safely go in the bin.

lead(II) nitrate <0.003 M (<0.1% wt/wt) 7-12 years
lead(II) nitrate 0.003-0.03 M (0.1-1% wt/wt) 11-12
lead(II) nitrate 0.03-0.18 M (1-6% wt/wt) and above including solid Teacher only
lead(II) nitrate 0.18-0.45 M (6-15% wt/wt)

that's according to Riskassess

Hi Everyone, I realise this thread is very old wondering what everyone does in the event of a spill. I dropped a jar of Meruric Iodide this morning that went everywhere. Cleaned up with safety glasses, apron, gloves but all I had was a blue covid mask. I cleaned up and put into a new storage contain...

Wanted to do in TAS rooms, but I've since spoken with 3 Chemistry teachers. Because I was made to feel like a fool, apparently there is still some fumes not as toxic but still enough that it really doesn't need to be done. This is for Polymers HSC Chem which is only touched on, the kids have already...

Afternoon everyone, any help or sugguestions for alternate practicals would be greatly appreciated. I have a teacher that wants to melt milk bottles in a saucepan over heat, apparently for year 12 chemistry. Would you be happy with this? or is there an alternative. I've been told it will not give of...

If you have a good HT I'd take it to them, I'm always sus with anything benzene or bromine. See what he is doing with it and the cost alone of the new chemicals for a once off, may be enough of a deterrent.

WOW I wish

Yep didn't take long, one email at 10.30pm last night didn't read till this morning. 3 teachers wanting pracs and saw the warning, they knew they were all pracs that were already made up so OKAY with that. Not the HT yet. They'll all realise they only have 9 days to go soon!!!! Then end of term yah!!!

Okay I've set mine too, 1 day to start, would like it to be 2 but lets see the reaction to this first. I'm away tomorrow so it will be interesting.

You could try CSA Glencore Mine in Cobar NSW 0268365100 I'm sure they wouldn't mind sending you some if you explain it's for Educational purposes.

Let me know how you go. Cheers

I just noticed it only came out yesterday on Riskassess!! lol It's in the news section at the bottom of the Home page.

I've only just found on Riskassess there is a Warning on short-notice bookings / Cut-off time if you go into the tools section. I don't know if I'm game to set ours most give me 2 days notice but HT believes 11pm friday is fine for 9.10 Monday :cheesy: :cheesy: :cheesy: Would love to know if anyone ...

In the past I've taken a photo, then put in the fridge over the weekend upside down so no condensation.

Hi, just use a wide sticky tape straight over the top. Contact and I don't get on that well! lol
