Re: waste bottle labels
We have individual waste bottles, eg, silver, lead, copper etc. We don't have a nitrates waste. If we should have one please let me know!

Re: Swan neck tubes
Hi Helen,
Yes we bend our own glass tubing. When I got to our school we had lots of glass tubing already here and decided to bend ourselves, so I've never looked online for a supplier.

Re: Flame Test
Hi all,
I was looking for info on flame tests and saw my above post which I said we use strontium chloride which is incorrect. We use strontium carbonate.
But my question is does anyone use strontium chloride? We have lots and have run out of strontium carbonate. Does it show the same colour?

Re: Iron III Nitrate
I'm sure it's only Iron (II) nitrate that needs to be made fresh. We've got droppers of Iron (III) nitrate that sit and wait to be used and no issues with it

Re: Banned from 1 NOV
Yes. I was listening and we cannot use them at all but they then said we can if it isn’t for a ‘supplied’ use like catering but if it’s used for experiments and can be reused it’s ok? So I hope this doesn’t mean we will get in trouble if audited. That’s how I understand it and now I’m not sure if we...

Re: Stocktake programs
Hi All, I've started using chemwatch for our stocktake, and I've added chemicals to each class, or location etc. but can anyone tell me if the SDS's get automatically updated? Previously we have downloaded them and saved as PDF's onto our computer, and we have an excel sheet with the issue dates and...

Re: Banned from 1 NOV
Do you know if this means we can't even have in on site from nov 1st?
Or no more purchasing from nov 1st?

Re: Ferrous sulphide sticks
Wow, good find.
We have one, its the same size as our flam liq, I think 200L approx. It was here when I got here. I think it's great, stores everything and easy to find it all.

Re: storage of corrosives
I did, I asked if they can take the old one to be disposed of but they don't, and they just said if there wasn't a spill it could probably be a general waste or maybe a metal recycling place.
Just thought I'd post the question hoping someone might know

Re: storage of corrosives
Hi, has anyone ever disposed of a corrosives cabinet, is it ok to just be put with general waste (there has been no spills in it) so i assume its fine.
Thought I'd ask.
Thanks

Re: Hydrogen peroxide
Hi,
One of my teachers has asked for 27% hydrogen peroxide. Does anyone know how I dilute to make this?

Re: Sodium Hydroxide solution on Risk assess
So for example, if you were asked for 1M sodium hydroxide in dropper bottles, and your label on them were the ones from risk assess, without the haz/precautionary statements, would you print a mini SDS for the prac, so they have the safety information on hand?

That makes sense. It's a nightmare trying to fit all the statements onto a label

Re: freezing coloured water
I've just been asked for blue ice cubes for tomorrow, I've got them in the freezer now with the salt method.
Thanks so much bigmack for doing that last year. I remember reading it and had to go and find it.
