I totally get that its wrong and out of date but, my question was how have DET schools been labelling their Lead nitrate in the last 21 years ?

How have DET Labbies interpreted the CSIS info on it and used it to label their Lead Nitrate solutions ?

Sorry Richard - seems like we all went off on a rant. If, according to CSIS, the solid is 7-12 and the solution of <1% is also 7-12, wouldn't everything in between be 7-12? That was the path I took many, many moons ago when I had to use CSIS.
I'm no good with the maths, but Riskassess has 0.003 to 0.03M as equivalent to 0.1-1%.
Although, given the discussion, for the safety of students, I would be labelling 0.003 to 0.03M as 11-12 and <0.003M as 7-12, in accordance with Riskassess guidelines. I'd be telling management to jam CSIS in their chem store!

Cobalt Chloride and Nickel Chloride are another two that concentrations have been drastically reduced. I think if I was in a DET school I would be pushing for HT to get Risk Assess, I know a lot in our area are using it. Not just our safety but everybody concerned it's kept up to date, any questions they are only a email away and reply the same day. Couldn't get better service for the little amount $250.

Teachers get used to it.

Read the SDS. It's what I always do, just to double check, it's up to us to protect our own health and that of the students.. I have Risk Assess too. It has saved me sooo much time labelling.
