SECTION 4. FIRST AID MEASURES

General Advice Show this safety data sheet to the doctor in attendance. Immediate medical attention is
required.
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 Remove 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.
Most important symptoms and effects
Causes burns by all exposure routes. Product is a corrosive material. Use of gastric
lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should
be investigated: Ingestion causes severe swelling, severe damage to the delicate tissue
and danger of perforation
Notes to Physician Treat symptomatically
