Chemical Storage - Not Segregated by Compatibility

Chemical Storage - Flammable Liquids in Refrigerators or FreezersAudit finding: Not segregated by compatibility

Adverse consequence(s): Fire, explosion, violent reactions, and/or release of toxic gases.

Corrective action: Chemicals must be classified by hazard class, and stored with regard to reactivity. Alphabetic order alone is insufficient, and chemicals must be stored in a single-layer. Use the printed hazard icons on chemical labels to determine hazard class, or the MSDS if the icons are not present. Information and examples may be found via on this link, and this link.

Example: Potassium Permanganate, a strong oxidizer reacting with Potassium Hydroxide, a corrosive solid.  Potassium Hydroxide is coated with the white crystals.
