SECTION 4. FIRST AID MEASURES

First Aid Measures
General advice Immediate medical attention is required.
Eye contact Immediately flush with plenty of water. After initial flushing, remove any contact lenses and
continue flushing for at least 15 minutes. Keep eye wide open while rinsing. Call a physician
immediately.
Skin Contact Immediate medical attention is required. Wash off immediately with soap and plenty of
water while removing all contaminated clothes and shoes.
Inhalation Immediate medical attention is required Remove to fresh air If not breathing, give artificial
respiration Avoid direct contact with skin. Use barrier to give mouth-to-mouth resuscitation
Ingestion Do NOT induce vomiting. Call a physician or poison control center immediately. Never give
anything by mouth to an unconscious person. Drink plenty of water.
