HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
Maintain good hygiene and clean-up practices in handling areas.
Ventilation:
Use general ventilation for normal handling.
Use local exhaust where dust may be generated during powder transfer.
Minimize airborne particulate accumulation in enclosed areas.
Storage:

Clean residues with water if needed and dry the area to prevent slip hazards.
Handling Precautions:
Balance E332 Potassium Citrates with E330 Citric Acid to achieve target pH, buffering behavior, and desired flavor profile because citrate salts can reduce perceived sourness.
Evaluate potassium taste impact because potassium salts can introduce bitter or metallic notes at higher levels in reduced-sodium designs.
Rotate stock using FIFO practices to maintain consistent quality and predictable buffering and chelation performance.
