Subject: 2 RE: [DCHAS-L] Methaneseleninic acid gloves?

 >We had a question about the correct gloves to wear when working with  
Methaneseleninic acid. The Sigma/Aldrich MSDS helpfully says "Handle  
with gloves", but given the stench and high toxicity of the material,  
the researcher (and we) would like something more specific. The  
process is weighing out and dissolving the powder in water.

My suggestion is to call Sigma Aldrich and ask them what their folks  
wear when they handle this stuff.  After all, they either make it or  
repackage it (or can ask their vendor what they use).  Be pushy if you  
need to be; I have had some very inexperienced "safety specialists"  
who basically read the MSDS and some very good ones.  The other  
alternative is to call one of the glove manufacturers, who have always  
been able to help me with these questions if the original vendor  
can't.  But SA is a big company and should be providing this  
information as a matter of 'product stewardship'.  If more people  
'bothered' them for this information they would rightly start adding  
it to the MSDS, where it belongs. Good luck.

The above is my personal opinion only, not legal advice and may not  
reflect the opinion of my employer or any group to which I belong.

When I don't know what gloves to recommend (and the manufacturer is no  
help), my fall back is Silver Shield with close-fitting nitrile over  

Good luck!
