Demystify: 

I don't know if this is applicable to your situation, but=20 there are volatile nickel compounds, such as nickel dimethylglyoxime.  As I=20 recall from an analytical course I took long ago, one had to be careful drying=20 NiDMG because one risked loss to evaporation.  (Of course, were nickel=20 tetracarbonyl forming there would have probably been fatalities by=20 now.)
 
Is it possible to simply clean off the corroded nickel?

Subject: [DCHAS-L] Autoclave corroding and=20 nickel toxicity

Good afternoon,

 

I received a question this afternoon about an autoclave=20 chamber that has been deemed “decaying and hazardous.”

 

The individual was told that the nickel plating on the=20 chamber is corroding and that users are at risk of experiencing nickel=20 toxicity.  The solution = buy a new autoclave, which the service person=20 also sells.

 

I can’t find anything to back this claim up (besides=20 discussions re: teapots). 

 

I appreciate any and all comments/suggestions.

 

Thank you!

 

~Suzy Arnette
