ferric nitrate?

Post by Kathryn »

Hi all
Just started the annual chemical inventory and SDS update and have noticed a discrepancy in ferric nitrate classification. The original container (which is old) and Riskassess class it as DG 5.1 whereas the SDS has it as DG8. It has always been stored with the other oxidisers but now I am not sure what I should do with it???
Any suggestions?

I have mine with the corrosive bases. The SDS from the specific manufacturer is what you should rely on. It wouldn't hurt to send Riskassess an email and point out the conflicting information.

True Labbie , but Kathryn's not DOE .

Chemsupply ,Merck, sigma aldrich latest SDS's have it as Corrosive .
Older MSDS's have it as Oxidant .

Must have been reassessed at some stage recently .

I think this highlights the problem of CSIS and the sad state of affairs when DoE staff are told to follow it. It is very, very, out of date.

Absolutely. What will it take for this to be taken seriously? Who will take responsibility?

I just checked in with Risk Assess, and it is also classed as a 5.1 there.

Yes Riskassess has it as 5.1 and so does the original container which is why I am reluctant to move it out of Oxidisers.

The safety data sheet has the most up to date information. That's why they get updated every five years.

Well this is where , I'm confused .

Kathryn , what brand is the Ferric nitrate and can you still find an up to date SDS for it or is really old and you are using a Generic SDS ?

I was under the impression that Risk assess got their info from Work Safe who rely on the latest European standards .
So how can the latest SDS's from three big Chem suppliers say one thing when the latest European standards are saying something else ?

It's possible that they are wrong. Safework says we should rely on the information on the safety data sheet provided by the manufacturer or supplier. So, although Riskassess may be right (but they could be wrong), our legal obligation is to follow the advice from the manufacturer, not from a third party.

If you have a chemical that was produced by a company that no longer exists, Safework would say to dispose of it and buy new chemical. I'm not sure if they would prosecute a school because you were relying on a SDS for a different brand of what is essentially, the same thing. That something for you to decide upon. Of course, if you have a product that is made up of a combination of things, eg a cleaning product, it must be the right manufacturer as each product will be slightly different. A substitute SDS would not be anywhere near acceptable in this situation.

If in doubt, I would contact Riskassess and the supplier to ask for clarification. At the end of the day, we are in a school with relatively small quantities, I wouldn't panic over it until you get a response from these two organisations.

Does this help at all Bigmack?
