Yes, incompatible materials is a key phrase! You also can't just store all acids together. They can have some very bad reactions when mixed.

Try your State Fire Code, most if not all will be based on the IFC. In North Carolina, I could cite at least one code where this is addressed: Chapter 27, General Provisions -2703.9.8 Separation of incompatible materials.

I always wince when I hear your question. It usually means some employer has said "show me an OSHA regulation that says I have to do that and I'll do it." OSHA is the "minimum" in safety and a weak fish when it comes to standing on it's hind legs that you follow OSHA at your peril.

I suggest you go to OSHA's web site and search for "storage of reactive chemicals" About 4th or 5th down will be a letter of interpretation from 2001 in which OSHA says that that flammables and corrosives can be stored in the same cabinet if the manufacture's rules for storage on the MSDS for the chemicals says it is OK and the containers are of the right type, etc. Well, not good practice. And it would mean checking each corrosive's data to see if there are any solvents in the cabinet with which it can react.

And will following this corrosive by corrosive policy protect your liability should there be a problem? Not likely. The lawyers will probably bring NFPA and other storage standards to court and ask why you didn't follow accepted practice.

It is such a little thing to just purchase corrosive and flammable cabinets and teach people to use them properly -- problem solved. That is the only option my reports recommend, ever.

Can anyone give me a regulatory citation or safety association/ research institute code for storing acids and bases separately? I know it is a good practice, but want a reference from a recognized entity.

Thanks!
