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.
