This is what Riskassess states. It's an ongoing problem here don't like it at all. So many alternative can be used sodium tetraborate, anhydrous(borax) Class:ncPG:noneUsers:Tch Training:1,2,5CAS: 1330-43-4 GHS data: DANGER Health hazard May damage fertility.

Westlab have some distillation kits but EUD needed. Can't seem to find anything for spare parts either.

Just found Science supply have kit and larger flasks and some parts

Hi Brains trust, I'm now job sharing, I'm looking at giving she and I a colour sticker each to put on Stock bottle, diluted and dropper bottles this is what I had in mind. New solution Date (8/24) Diluted from stock solution 8/24 D Decanted from Diluted stock solution 8/24 DD Please let me know what...

I wouldn't be using HCl kids aren't allowed to use concentrated even if they are going to dilute it. 10M they are, why can't the use 1.0M 50mls it would still work and not be as dangerous. We also have the plastic burettes so I guess that would make it easier.

For those who refuse to make up bromine water from scratch. (after a bad accident) Georgia Deretic who co-wrote Foschem Senior Chemistry gave me a substitute that works just as well and less dangerous. Bromine in Situ 100 mls 2m Sulfuric Acid 50 gms Potassium Bromide Dissolve Add drop by drop of Hyd...

Same here I've only ever done Mini SDS in Science Lab and Main Office, we are audited internally and externally to often to count since 2001 and have never had a problem. When and if we do I'll look at full SDS. Was always told if there is a fire, you get out! the place is insured. Except for the od...

Thank you, let Charlie know I just couldn't out last her lol he'll know what I mean

Hi Everyone, I'm going part time after 29 years in the same place, if anyone is interested in a country change. I'm a little nervous after working full time my entire life, part time every school holidays when I was a teenager, it's time!! \:D/ :unsure: Following the link below https://teacherson.ne...

I'm glad it's not just me the decline over the last 20 years is scarey. Even the pracs I'm asked to prepare some days, I feel like a kindergarten assisstant. There needs to be boundies some not all teachers, "the need to be friends with the kids". Build a rapport yes! kids aren't stupid gi...

They've stretched the springs, so just going to throw out and replace. Some were old metal ones and old plastic, how you can't see when the kids are doing the wrong thing, I don't know.

Morning brains trust,

I've just had a Yr 7 class using the spring balances with 250 gm masses. They have been swinging them to measure angle. Well now most are broken any idea on how I could fix them, trying to get them apart is a nightmare. Or just replace.

love ours, is a lot brighter in colour than the photo. Mounted on a black board.

I haven't heard anything about Mercury being banned from schools? The old thermometers have been for years. We still have a sample inside a small glass container sealed inside another labeled container for viewing only kids are allowed to feel the total weight of the container. RiskAssess still has ...

Maybe they just hit the ground and kept running, away... Welcome back!! that's exactly how I felt. Sadly still here. Arrived first day back and Fridge/freezer full of Dissection had gone off!! OMG this is the second time in 29years. Hopfully I never see it again. Our maintenance men removed from th...

We go by RiskAssess as well. CSIS hasn't been updated for decades, the Dept must be waiting for a legal case before they start?? It's bound to happen, one day, sadly. Had to laugh at this, but it isn't really a laughing matter! I went to a general WHS course run by AIS and, can you believe, they sa...

RiskAssess is as followings;

Nickel Sulfate Solid (Tch)
<0.006M (7-12)
0.006M - 0.065M (11-12)
0.065M - 0.16M (Tch)

I only use RiskAssess now

Hi Stuart,

Mine have just arrived and I can't thank you enough they are fantastic, I can't wait to show the chemistry teachers and kids.

Thanks you so much for all your hard work.

As Anna Z said you're a legend

Thank you Stuart, Can't wait till they arrive. Teachers are already excited, the booklet I have printed out for each of them.

Go to the ChemSupply website. You don't have to login. You can access Safety Data Sheets for most of the chemicals that you would have in stock.

I don't know if ths still applies I have used in the past.
