V HEALTH HAZARD INFORMATION
Effects of Exposure:
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.
As regards local effects, copper chloride and sulfate have been reported as causing irritation of the skin and conjunctiva which may be on an allergic basis. Cuprous oxide causes irritation to the eyes and upper respiratory tract. Discoloration of the skin is often soon in persons handling copper, but this does not indicate any actual injury from copper. There is an excess of cancer cases in the Cu smelting industry.
In man the investigation of a large quantity of copper sulfate has caused vomiting, gastric pain, dizziness, exhaustion, anemia, cramps, convulsions, shock, coma and death. Symptoms attributing to damage in the nervous system and kidneys have been reported, jaundice has been observed and, in come cases, the liver has been enlarged. Deaths have been reported to have occurred following the ingestion of as little as 27 g of salt, while other victims have recovered after having much larger amounts, up to 120 g.
Health Hazards (Acute and Chronic):
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.
Eye: Irritation, watering, redness possible. Risk of serious injury.

SKIN: Wash skin with mild soap and water. Seek medical assistance as necessary, especially if irritation develops or persists.
INHALATION: Remove to fresh air. Seek medical attention immediately. Give oxygen if breathing is difficult.
INGESTION: SEEK MEDICAL ATTENTION IMMEDIATELY. Give 1-2 cups of milk or water and induce vomiting.

VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wearing a self-contained breathing apparatus and full protective clothing, isolate the area where the spill occurred. Insure proper ventilation is available and that water/moisture are kept out of out of the area. Vacuum up the spill using a high efficiency unit and place in a container for proper disposal. Take care not to raise dust.
Waste Disposal Method: Disposal must be made in accordance with Federal, State and Local regulations.
