SECTION 4. FIRST AID MEASURES

General Advice Show this safety data sheet to the doctor in attendance. Immediate medical attention isrequired.
Eye Contact Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Immediate medical attention is required. Keep eye wide open while rinsing.
Skin Contact Wash off immediately with soap and plenty of water while removing all contaminated
clothes and shoes. Call a physician immediately.
Inhalation Move to fresh air. If not breathing, give artificial respiration. Call a physician or Poison
Control Center immediately. Do not use mouth-to-mouth method if victim ingested or
inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with
a one-way valve or other proper respiratory medical device.
Ingestion Immediate medical attention is required. Do not induce vomiting. Drink plenty of water.
Never give anything by mouth to an unconscious person.
