I agree with Russ. Plastic trays or other compatible containers are the best. Make sure that the trays are large enough to hold the contents of the materials you are storing. Good Luck Andrew.

Use SECONDARY CONTAINMENT on those bottles! Put them in plastic trays or some other form of containment that will hold liquid before you put them on shelves. Also - the shelves should ideally be made of a composite material or treated wood - not metal. Metal shelves will rust rapidly in the presence of corrosive materials. You should also check out your ventilation.

Subject: [DCHAS-L] Safe Storage of Chemicals
If you remember I recently got a job and all is going great. I'm
trying to reorganize the lab being many of us are new. So far I have
isolated bulk/strong acids and bases in their own cabinets. We also
have many acids and bases that we use day to day and keep them out in
the open. Most of them are relatively weak, but some are very strong.
In the past, the company kept things at workstations. I (and my boss)
didn't think that was a very good idea. To much clutter, to many
expired/unstandardized chemicals going un noticed and to many
duplicates. We decided on one bottle of everything, no more, but
perhaps less (zero) if it isn't used often and easy to make.
To my question, these small (less then 1L) caustics need to be left
out, eventually I'll push for a proper storage cabinet for non-bulk
items, but until then they are on a shelf. I decided to store the
acids on the bottom shelf of the left bay, and the bases on the bottom
shelf of the right bay with neutral solutions on the top shelves and
in the middle bay. My philosophy being that if the bottle falls, it
doesn't fall far. If it leaks, it leaks on empty bench space, and if
it does spread to surrounding chemicals, it is either a like chemical
or a neutral chemical. All acids and bases are at least 4ft apart
separated by 2 shelf walls.
I don't have much to work with, I know it could be a lot safer, but if
anyone can think of any ideas with what I described I would like to

As a trained chemist who has worked extensively with pyrophoric materials, I am angry over your attitude that lab workers should not be allowed to extinguish small lab fires. As an educator, I would not let students use flammable liquids in a lab unless an extinguisher was available for me to use in any incidents.

Whomever first discovers the small hood fire should put it out if they can do so safely, and yes, those of us who have handled dangerous materials, know a thing or two about working safely. And, no, I would try to fight a large fire. Yes, someone has to use their judgment when assessing the situation.
