FIRST AID

Inhalation:
Move to fresh air if fumes or aerosols are inhaled during heated processing.
Seek medical attention if respiratory irritation persists.
Avoid breathing aerosols during high-shear or hot operations.

Skin Contact:
Wash with soap and water after contact.
For molten product contact, cool the 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.

Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or if a significant amount is swallowed.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care as needed.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses, especially when handling molten material.
Avoid splashing into eyes and avoid prolonged skin contact with hot product.
Wash hands after handling and before eating, drinking, or smoking.

Ventilation:
Use general ventilation for normal handling.
Use local exhaust if heated processing generates fumes or aerosols.
Avoid aerosol formation in enclosed spaces without adequate airflow.

Storage:
Store in tightly closed containers in a cool, dry place away from heat sources.
Protect from moisture contamination and strong odors because fats can absorb odors.
Keep containers properly labeled and protected from contamination.

Spill and Leak Procedures:
For solids, collect spilled material and clean residues to prevent slip hazards.
For molten spills, allow to cool and solidify, then remove mechanically.
Dispose of waste according to local regulations and food industry procedures.

Handling Precautions:
Select the correct grade based on emulsion type, whipping performance goals, and melting behavior to ensure consistent functionality.
Control processing temperature and shear to achieve proper dispersion and stable emulsion formation.
Rotate stock using FIFO practices to maintain consistent quality and predictable functional performance.
