EXPOSURE


Inhalation
Ventilation.
Fresh air, rest.
Skin
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Rest.
