Seek medical attention if irritation persists or if hot material contacted the eye.
Ingestion:
Rinse mouth with water.
Do not induce vomiting unless directed by medical personnel.
Seek medical attention if a large amount is swallowed or discomfort occurs.
Note to Physicians:
Treat symptomatically.

HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses.
Avoid dust generation during handling of flakes or pellets.

Avoid overheating and minimize vapor exposure in enclosed areas.
Storage:
Store in a cool, dry place away from direct sunlight and heat sources.
Keep containers tightly sealed and properly labeled.
Protect from contamination and moisture to maintain quality and consistency.
Spill and Leak Procedures:
For solid material, sweep up and collect without generating excessive dust.
For molten material, allow to cool and solidify before removal.
Clean residue with detergent and water while preventing slip hazards.
Handling Precautions:
Use dedicated, clean equipment for cosmetic, pharmaceutical, or food-contact supply chains when applicable.
Avoid contact with strong oxidizers and maintain good housekeeping to reduce slip and dust hazards.
Rotate stock using FIFO practices to maintain consistent quality and performance.
