First Aid Measures
Emergency procedures for chemical exposure incidents
After inhalation: fresh air. Call in physician.
Take off immediately all contaminated clothing. Rinse skin with water/ shower. Consult a physician.
After eye contact: rinse out with plenty of water. Call in ophthalmologist. Remove contact lenses.
If swallowed: give water to drink (two glasses at most). Seek medical advice immediately. In exceptional cases only, if medical care is not available within one hour, induce vomiting (only in persons who are wide awake and fully conscious), administer activated charcoal (20 - 40 g in a 10% slurry) and consult a doctor as quickly as possible.
