V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of silicon carbide have not been thoroughly investigated and reported. Silicon carbide is a nuisance dust capable of producing nonprogressive pulmonary fibrosis. Silicon carbide implants have caused tumors in laboratory animals.
Inhalation: May cause irritation.
Ingestion: No acute health effects recorded.
Skin: May cause abrasive irritation.
Eye: May cause abrasive irritation.
Inhalation: May cause pneumoconiosis.
Other: No other chronic health effects recorded.
Target Organs: No target organs recorded.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders.
Carcinogenicity: NTP? No IARC Monographs? No OSHA Regulated? No
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention if symptoms persist.
INGESTION: Seek immediate medical advice.
SKIN: Wash thoroughly with mild soap and water. Seek medical attention if symptoms persist.
EYE: Flush with lukewarm water, lifting upper and lower eyelids for at least 15 minutes. Seek medical attention if irritation persists.
VI REACTIVITY DATA
Conditions to Avoid: None
Incompatibility (Material to Avoid): Oxidizing agents.
Hazardous Decomposition or Byproducts: Carbon monoxide and carbon dioxide, silicon oxide.
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 local, state, and federal regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: Dust respirator, NIOSH approved.
Ventilation: Use local exhaust to keep levels below TLV. General ventilation is recommended.
Protective Gloves: Rubber gloves
Eye Protection: Safety Glasses
Other Protective Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Other Handling and Storage Conditions: Store in airtight containers in a cool dry place. Keep container closed when not in use. Wash thoroughly after handling. Store away from oxidizing agents. Ensure good ventilation in the workplace.
Work 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 or smoking. Do not blow dust off clothing or skin with compressed air.
The above information is believed to be correct, but does not purport to be all inclusive and shall be used only as a guide. ESPI shall not be held liable for any damage resulting from contact or from handling the above product.
