Seek medical attention if irritation persists.
Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or if a large amount is swallowed.
Never give anything by mouth to an unconscious person.
Note to Physicians:
Treat symptomatically.
No specific antidote is required.

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:
Store in tightly closed containers in a cool, dry place.
Protect from moisture to prevent caking and maintain free-flowing behavior.
Keep containers properly labeled and protected from contamination.
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:
Select the correct E450 Diphosphates type because E450 Diphosphates can be acidic, neutral, or alkaline and strongly affect pH and functional performance.
Control dosing because E450 Diphosphates can change taste, mineral balance, and texture when overused.
Confirm regulatory permission and maximum use levels because phosphate limits vary by market and product category.
