Section 4 - First Aid Measures
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper
and lower lids until chemical is gone. Get medical aid at once.
Skin:
Get medical aid at once. Immediately flush skin with plenty of soap and water for at least 15
minutes while removing contaminated clothing and shoes. Remove contaminated clothing to reduce
further exposure.
Ingestion:
Do NOT induce vomiting. Give conscious victim 2-4 cupfuls of milk or water. Never give anything
by mouth to an unconscious person. Get medical aid at once.
Inhalation:
Move victim to fresh air immediately. Give artificial respiration if necessary. If breathing is
difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
General Information:
