Sodium Metabisulfite Handling and Storage

Sodium Metabisulfite Preservative Handling and Storage

Prior to working with Sodium Metabisulfite you should be trained on its special handling and storage. Contact with moisture or water will release sulfur dioxide gas.  The bulk materials must be stored in a cool and well-ventilated area to avoid heat, moisture or combustible materials and segregate from acids and oxidizers.
