Exposure effects
The details of the toxicity of nitrides as a group are unknown. However, many nitrides react with moisture to evolve ammonia. This gas is an irritant to mucous membranes. As the sublimed oxide, copper may be responsible for one form of metal fume fever. Inhalation of copper dust has caused, in animals, hemolysis of the red blood cells, deposition of hemofuscin in the liver and pancreas, and injury to thee lung cells. Injection of the dust has caused cirrhosis of the liver and pancreas, and a condition closely resembling hemochromatosis, or bronzed diabetes. However, considerable trial exposure to copper compounds has not resulted in such disease.
   Inhalation
A respiratory irritant. Coughing, sneezing, difficulty breathing and pulmonary edema possible. May cause irritation of the mucous membranes of the nose and throat.
   Skin
Irritation, inflammation, redness possible. May cause dermatitis.
   Eyes
Irritation, watering, redness possible. Risk of serious injury.

First aid
 
   Ingestion
SEEK MEDICAL ATTENTION IMMEDIATELY. Give 1-2 cups of milk or water and induce vomiting.
   Inhalation
Remove to fresh air. Seek medical attention immediately. Give oxygen if breathing is difficult.
   Skin
Wash skin with mild soap and water. Seek medical assistance as necessary, especially if irritation develops or persists.
   Eyes
Flush with copious amounts of water for at least 15 minutes and seek medical attention.
