What I do for labs like this is have them store the acetic acid in one secondary container and the hydrochloric acid in a different one, but they can both stay in the same corrosives/acid cabinet. That way, if there is a spill or a bottle breaks, they are separated to minimize contact and are also in compatible storage containers.
I'm interested to hear what others think and if I'm doing it wrong, I definitely want to fix it! I'm still relatively new to my position and I'm always looking for ways to improve.

Good evening--
The chemical compatibility charts I've reviewed indicate inorganic acids should be stored separately from organic acids. This makes sense if a lab is storing a variety of both types. We all know what happens with nitric acid and organic acids..
However, we're renovating a geology lab that uses mostly hydrochloric acid and occasionally uses acetic acid, both ACS grade (which are further diluted before using to digest rock or soil samples). I have reviewed both Sigma and Fisher SDS's for these two materials, and it does not seem to me that storing several 500mL-1 Liter bottles of each together in a corrosives cabinet would be incompatible storage or create a safety risk. Storing them with caustics, permanganates, oxidizing acids, metals--that would be a concern, but this lab doesn't use any of these incompatible reagents.
Thoughts? Am I missing something?
Many thanks as always-
Margaret
