V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of copper silicide have not been thoroughly investigated and recorded.
Copper compounds: In animals, inhalation of copper dust has caused 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 of the liver and pancreas, and a condition closely resembling hemochromatosis or bronzed diabetes.
Routes of Entry: Inhalation, ingestion, skin, eyes.
Acute Effects:
Inhalation: May cause a metallic taste in the mouth, congestion of the nasal mucous membranes, irritation to the respiratory tract.
Ingestion: Poison by intraperitoneal route. May cause acute copper toxicity.
Skin: May cause irritation.
Eye: May cause irritation to the conjunctivae.
Chronic Effects:
Inhalation: May cause ulceration and perforation of the nasal septum and pharyngeal congestion.
Ingestion: May cause irritation to the gastrointestinal tract and chronic copper toxicity. May cause damage to the nervous system, kidneys and enlarge the liver.
Skin: May cause dermatitis.
Eye: No chronic health effects recorded.
Target Organs: May affect the respiratory system, skin , liver, central nervous system, an kidneys.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory, gastric disorders and an increased risk for individuals with Wilson’s disease.
Carcinogenicity: NTP: No IARC: No OSHA: No
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek medical attention immediately. Never induce vomiting or give anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water, seek medical attention if symptoms persist.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.
VI REACTIVITY DATA
Stability: Stable
Conditions to Avoid: None
Incompatibility (Materials to Avoid): None recorded
Hazardous Decomposition Products: None recorded
Hazardous Polymerization: Will not occur
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material is Released or Spilled: Wear appropriate respiratory and protective equipment specified in Section VIII. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.
Waste Disposal Method: Dispose of in accordance with Federal, State and Local regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH approved respirator
Ventilation: Use local exhaust to maintain concentration at or below the PEL, TLV. General exhaust is recommended.
Protective Gloves: Rubber gloves
Eye Protection: Safety glasses
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a tightly sealed container. Store in a cool, dry area. Wash thoroughly after handling.
Work/Hygienic/Maintenance Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and smoking. Do not blow dust off clothing or skin with compressed air.
