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
