IV FIRE AND EXPLOSION HAZARDS DATA
Flash Point (Method used): N/A Autoignition Temperature: N/A
Flammable Limits: Upper: N/A Lower: N/A Flammability: Non-flammable
Extinguishing Media: Use dry chemical, CO2.
Special Fire Fighting Procedures: Wear a self-contained breathing apparatus and full protective clothing to prevent clothing to prevent contact with skin and eyes.
Unusual Fire & Explosion Hazard: When heated to decomposition, copper oxide may emit toxic fumes.
V HEALTH HAZARD INFORMATION
Route(s) of Entry: Inhalation, skin, ingestion
Effects of Over Exposure:
Inhalation: May cause coughing, sneezing, difficulty breathing and irritation of the mucous membrane of the respiratory tract.
Dermal: May cause irritation, itching, inflammation and dermitits.
Eye: May cause burning sensation, irritation, redness and watering of the eyes if comes in contact.
Medical Conditions Generally Aggravated by Exposure: Respiratory disorders.
Carcinogencity: None NTP? No IARC Monographs? No OSHA Regulated? No
Other: Copper Compounds: 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 the lung cells; injection of the dust has caused cirrhosis in the liver & pancreas, a condition resembling hemochromatosis, or brionzed diabetes. However, considerable trial exposure to copper compounds has not resulted in such disease.
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove to fresh air, give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 cups of milk or water and induce vomiting. Seek medical attention.
SKIN: Brush off skin, wash area with soap and water and seek medical attention.
EYE: Flush eyes with lukewarm water for 15 minutes and seek medical attention.
VI REACTIVITY DATA
Stability: Stable
Conditions to Avoid: Heat, flame and incompatible materials.
Incompatibility (Materials to Avoid): Peroxyformic acid.
Hazardous Decomposition Products: Cu, CuOx fumes.
Hazardous Polymerization: Will not occur.
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear a self-contained breathing apparatus and full protective clothing. Isolate the area where the spill occurred and insure proper ventilation is available. 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: In accordance with Local, State and Federal Waste Disposal Regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): Wear NIOSH-approved dust-mist-fume cartridge respirator.
