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

HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
