Corrosive storage cabinets Corrosive chemicals should be kept in cabinets specifically designed to hold them. A wooden storage cabinet or metal cabinet treated with a corrosion-resistant coating is available commercially. Store organic and inorganic acids separately, either in different storage cabinets, or separated by distance or barrier. Store nitric acid away from all other acids unless your cabinet has a separate compartment for nitric acid. Gas cylinders Storage of pressurized gas cylinders should be in accordance with Chapter 6150 Compressed Gases .
Refrigerators Use explosion-proof refrigerators for cold storage of flammable chemicals.
The various control switches and defroster heaters on household-type refrigerators can spark and ignite flammable chemicals. Food should never be stored in a refrigerator used for chemical storage. Always keep all flammable chemicals away from ignition sources. If only one acid cabinet is available, use it for the inorganic acids. Nitric acid must be stored separately.
