If breathing is difficult, trained personnel should provide oxygen and seek urgent medical care.

Skin Contact:
Remove contaminated clothing and rinse skin with plenty of water.
Wash thoroughly with soap and water after rinsing.
Seek medical attention if irritation persists, and seek urgent care for significant exposure because skin absorption is possible.

Eye Contact:
Rinse cautiously with water for at least 15 minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek immediate medical attention because eye exposure can be serious.

Ingestion:
Rinse mouth with water and do not induce vomiting.
Seek immediate medical attention or contact a poison center.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.
Monitor for central nervous system effects and respiratory irritation.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including chemical-resistant gloves, goggles or face shield, and protective clothing.
