Just to add to this one:
Do I need to put some/all of them in a yellow steel cabinet?
I believe the yellow steel cabinet you are referencing is a flammable cabinet? That wouldn't really be an SQF/food safety thing, although they COULD give you a finding if they are familiar with the regulatory requirement and you are in violation. It would be an OSHA/NFPA compliance requirement. I'd suggest doing some searches on the requirements with NFPA (OSHA typically defers to them) to find out if you have flammable liquids in the quantities (Cat 1-3 have different gallon requirements/restrictions and you might need several compliant cabinets) they require to be maintained in complaint flammable storage containers.
