EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Cough. Burning sensation. Sore throat. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes).
Breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. No mouth-to-mouth artificial respiration. Administer oxygen by trained personnel. Refer for medical attention.
 •SKIN MAY BE ABSORBED! Pain. Redness. Blisters. Serious skin burns.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Wear protective gloves when administering first aid. Refer for medical attention.
 •EYES Causes watering of the eyes. Redness. Pain. Severe deep burns. Permanent loss of vision.
Safety goggles and face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Abdominal pain. Nausea. Vomiting. Burning sensation. Shock or collapse. (See Inhalation).
Wash hands before eating. Do not eat, drink, or smoke during work.
Do NOT induce vomiting. No mouth-to-mouth artificial respiration. Administer oxygen by trained personnel. Refer for medical attention.
