FIRST AID

Inhalation:
Move to fresh air if dust is inhaled.
Seek medical attention if respiratory irritation persists.
Avoid breathing dust during powder handling.

Skin Contact:
Wash with soap and water after contact.
Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or if a large amount is swallowed.
Zinc ingestion can cause gastrointestinal upset at high doses, so keep out of reach and follow dosage guidance.

Note to Physicians:
Treat symptomatically.
Consider zinc salt exposure and gastrointestinal irritation based on amount ingested.
Provide supportive care as needed.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
Prevent contamination and use clean, food-grade equipment for weighing and blending.

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:
Store in tightly closed containers in a cool, dry place.
Protect from moisture to prevent caking and maintain free-flowing behavior.
Keep away from strong bases, strong oxidizers, and incompatible materials.

Spill and Leak Procedures:
Sweep up spilled powder and avoid dust generation.
Collect into suitable containers for reuse or disposal according to local regulations.
Clean residues with water if needed and dry the area to prevent slip hazards.

Handling Precautions:
Calculate zinc contribution correctly because hydrate form affects dosing and label claims for zinc content.
Evaluate formulation interactions because zinc can precipitate with phosphates and interact with proteins and polyphenols, affecting clarity and taste.
Rotate stock using FIFO practices to maintain consistent quality and predictable fortification performance.
