SECTION 4: First Aid Measures
Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need
Eye Exposure:
assistance in keeping their eye lids open. Get immediate medical attention.
Wash the affected area with soap and water. Remove contaminated clothes if necessary. Seek medical
Skin Exposure:
assistance if irritation persists.
Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty
