FIRST AID

Inhalation:
Move to fresh air if dust, fumes, or mists from heated material are inhaled.
Seek medical attention if respiratory irritation persists.
Avoid breathing fumes when heating or melting the material.

Skin Contact:
Wash with soap and water after contact.
If molten material contacts skin, cool the affected area with water and seek medical attention for burns.
Remove contaminated clothing and wash before reuse.

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 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.
Manage burns as needed if exposure involved molten material.
Provide supportive care based on exposure route and symptoms.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses.
Avoid dust generation during handling of flakes or pellets.
Use caution when heating or melting to prevent burns.

Ventilation:
Use local exhaust or general ventilation where dust may be generated.
Provide adequate ventilation during heating to avoid inhalation of fumes.
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.
