Skin contact: Take off immediately all contaminated clothing. Rinse skin with
water/shower. Call a physician or poison control center immediately. For
minor skin contact, avoid spreading material on unaffected skin.
Eye contact: Rinse cautiously with water for several minutes. Remove contact lenses,
if present and easy to do. Continue rinsing. Call a physician or poison
control center immediately. Irritation of eyes and mucous membranes.
May cause temporary blindness and severe eye damage. Symptoms
may include stinging, tearing, redness, swelling, and blurred vision.
Ingestion: Call a physician or poison control center immediately. Rinse mouth. Do
not induce vomiting without advice from poison control center. Do not
induce vomiting. If vomiting occurs, keep head low so that stomach
content doesn't get into the lungs. Aspiration may cause pulmonary
edema and pneumonitis. Do not use mouth-to-mouth method if victim
ingested the substance. Induce artificial respiration with the aid of a
pocket mask equipped with a one-way valve or other proper respiratory
medical device.
