Also under the corrosive you have oxidizing acids and organic acids as incompatible.

I forgot to change the Subject line. I just thought I would pass this along to my safety colleagues around the country. A former student and his mother came by campus today. He is on a long road to recovery from severe injuries in an industrial accident. He wanted me to know that the safety training he received here saved his life. Never doubt that what we do is important!! Shelly Bradley ------------------------------ Date: Tue, 23 Jul 2013 19:27:09 -0400 Ralph, I have not had the chance to really review the issue yet. I would like to request list members to provide any and all examples of incompatible storage issues that they are aware of under GHS. I would like to add these bullets to the training to be provided shortly BruceV From: DCHAS-L Discussion List [mailto:dchas-l**At_Symbol_Here**MED.CORNELL.EDU] On Behalf Of Kevin Creed Hi Ralph, Also . under 'acutely toxic (Severe)' you could get incompatibles, e.g., cyanide salts and concentrated nitric acid.

So you can not rely completely on GHS for storage, as these products are not compatible.

that is due before December. Since I have not seen anything equivalent or
similar on the "official" pages, the list may be a great place to start the discussion.
