Rinse mouth with water.
Seek medical attention if discomfort occurs.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.

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.
Use closed transfer or local exhaust to minimize airborne dust during dosing and mixing.

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 preserve adsorption capacity and prevent caking of the additive itself.
Keep away from strong acids and incompatible chemicals.

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:
Optimize dosage because E553a (i) Magnesium Silicate strongly affects flow and excessive levels can influence appearance or mouthfeel in some powdered foods.
Control moisture exposure because E553a (i) Magnesium Silicate works by adsorption and can lose effectiveness if it absorbs moisture before use.
Rotate stock using FIFO practices to maintain consistent quality and predictable anti-caking performance.
