First-aid measures

General advice
Take off contaminated clothing and shoes immediately.

Remove to fresh air. Give oxygen. If symptoms persist, call a physician.

Skin contact
Wash off immediately with plenty of water for at least 15 minutes. Call a physician immediately.

Eye contact
Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

In the case of spontaneous vomiting, hold person's head low to prevent inhalation into the wind-pipe. Rinse mouth with water. If conscious, drink plenty of water. Call a physician immediately.

Most important symptoms and effects, both acute and delayed
Lungs: Depending on the concentration coughing, asthmatic reaction, glottis edema, pulmonary edema.
Eyes: Depending on the concentration conjunctivitis to severe chemical burn of the cor-nea/necrosis, iritis.
Skin: Irritation up to severe chemical burn
Ingestion: Depending on the concentration irritation to severe chemical burn of the affected esophageal, gastric and intestinal mucosa (risk of perforation!), cardiac reaction, respiratory distress, acid-base balance disorders, cramps.

Notes to physician / Possible hazards
Deep skin or corneal necrosis, pneumonia, esophageal/gastric perforation, pulmonary edema (up to 2 days latency time).

Indication of any immediate medical attention and special treatment needed
Irritation of the skin and mucus membranes can be treated with corticosteroids.
Provided there are no signs of esophageal and gastric perforation, an immediate gastric lavage using a large-bore gastric probe is useful (leave probe until at the hospital). Subsequent admin-istration of charcoal powder useful.
Anti-aspiration prophylaxis possible through early intubation.
With respiratory and pulmonary damages as well as large-area chemical skin burns antibiotic prophylaxis useful.
Treatment of severe chemical burns is the same as with thermal burns.
Treat symptomatically.
