They probably get a cleaner in on minimum wage.

I've just found out that we do indeed have starter pistols and caps in the school, and they have never been included on the chemical register. My head hurts.

We sure don't

you also need the full sheet on file and available to all staff that use the chemicals. Who would not even know where they were or care for that matter!! I sometimes wonder why I bother. No one EVER looks at them except me. Our head teacher wouldn't even know if they were up to date. One of those t...

Hi all, atecher just bailed me up and asked if I had a starter pistol. 8-[ I said no, but PD might . he wants to do some prac timing the puff of smoke till they hear the crack or some such thing. Does anyone know if you need a special license to use them? I can't find any mention on riskassess. Than...

That's interesting, as they have some pretty dangerous chemicals

0.1% = 0.1 grams per 100mL (Mass/volume) so for citric and ascorbic acid, weigh out 0.5 grams, dissolve in 500mL. For acetic acid you will need to work out what % acetic acid you have in your stock solution. Glacial , according to the laboratory is18M at 99 -100%, so my calcs, 2M should be 11%, so 4...

I wouldn't think so Sunray. If the place stayed clean for more than 24 hours I might have some more motivation and job satisfaction. At this point it's not top of my list of priorities. I'm not as young and flexible as I used to be.

How much cleaning up of glassware & benches do you do? I know it says in CSIS that students should be cleaning their own glassware and bench areas, but some teachers are better at it than others (and some apparently still take their laundry home to mum!) As I've said before, I've spent the whole...

I have even been told that it is not my job to do the whole school, but when the info came in - guess whose desk it was passed to? When I queried that, I was told that "no one" else had the time, 'someone' had to do it, 'no one ' knew how, and 'everyone' knew I had the skills, then it all...

Is any one else have teachers starting to do pracs from the new textbooks and finding that they don't actually have 40kg of flour sitting around their prep room, and hydrogen peroxide doesn't come in 10L drums?!?!?

We had Yabbies, stick insects, fish tanks.. but because the HOD had to sign as Animal Welfare Officer and there are strict rules - we now have NONE. I am not sure whether I am sad or happy. At least I don't have to come in on holidays to feed fish or take 3 huge cages of stick insects home to take ...

Hi all, Does anyone have animals in their schools? At one stage we had a semi functioning fish tank, but the fish died off as the tank was at the back of a lab and would collect everything from chemicals, glassware, pens, paper and lunches. I think the last one went when some darling emptied a bottl...

Hire a chopper!

Could anyone tell me how they treat/deal with/dispose of waste potassium nitrate solution?
It is an oxidiser so really shouldn't be heated to recrystallise, and shouldn't be ground in case it sparks ?

Thanks

I spent 45 minutes with them yesterday trying to work out how to get the label to print the entire chemical name and not half of it . As other people have said, you used to be able to to manipulate the areas, but not any more. At the end of it I was no closer to a solution. How hard can it be.

Why do pms take so long to go through?

Smiley, I've sent you a PM. I f you have any advice or know someone who does I'd be grateful

Thanks.
