- Corrosive storage cabinets have to be sturdy and placed very low to the floor. When it comes to material, corrosive storage cabinets need to be made out of impervious (non-reactive-with-corrosives materials). Corrosive substances are required to be stored near a proper ventilation system.
- Consider secondary spill trays, like for example, plastic bins, to use them in cases when special storage considerations are necessary. Hence, glacial acetic acids need to be stored in a special flammables cabinet, but there should be also a secondary containment in case of spill.
- Third consideration that should not be neglected is the ventilation of vapours that might escape a container. Although the caps of acids and bases are usually tightly sealed, with time, vapours can slip from the cap of the container, which commonly results in crystal-like forms on the caps of chemical bottles.
ATTENTION: Never store any type of chemical under the sink, especially if a corrosive. The vapours of these acids and bases will provoke a plumbing-fixture corrosion under the sink.
How to store corrosive materials?
You already know that bases and acids are compatible to each other and they will cause a reaction if they come in contact. This is why they need to be stored in a way that they will be separated by a sufficient distance. Strong corrosive materials have to be stored in a special corrosive chemical cabinet coated with caustic-resistant material. Easy-flammable weak bases, like most of amines, need to be kept in a special flammables cabinet and they should also be properly ventilated in order to reduce the strong odour they produce.
