Again, remember to assess your needs and your available space.  Having said this:

 

If you plan to use nitric acid, you=92ll either need a cabinet just for nitric acid or an acid cabinet with a compartment for nitric acid (usually a polypropylene cabinet).  Under no circumstances store nitric acid (at any concentration) with organic compounds or with acetic acid (yes, I know acetic acid is an organic compound!)  These are mistakes many high school chemistry storeroom caretakers make, and they can be dangerous ones.

 

One final thought=97it=92s generally an unwise practice to store chemicals in a classroom, even if they are in a locked cabinet.  The chemical storeroom should be a dedicated room OFF LIMITS TO STUDENTS and with limited access to chemistry teachers and administrators.

>"For "corrosives" you want one cabinet for acids and one for bases." is not completely correct.  Storing incompatible acids with each other is not a good idea.

Obviously.  But up until I said something, everyone was just talking about one kind of cabinet.  This issue had to be opened.   Monona

I recently found gently used flammable cabinets on craigslist for about 1/3 the cost of new ones.  It's worth investigating...

Yes, you're correct - I should have said "at least one" instead of just "one" to avoid having that sentence taken out of context or in case a casual reader didn't notice that the paragraph that followed discussed the incompatibility issue in detail.

Thanks,

Rob
