Flammable Limits: Lower: N/A  Upper: N/A


Extinguishing Media: Use suitable extinguishing media for surrounding materials and type of fire.

Special Fire Fighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.

Unusual Fire & Explosion Hazard: Silicon monoxide may emit toxic fumes if involved in a fire. May be flammable and possibly pyrophoric on contact with air at extremely elevated temperatures.



V. HEALTH HAZARD INFORMATION


Effects of Exposure:


To the best of our knowledge the chemical, physical and toxicological properties of silicon monoxide have not been thoroughly investigated and reported.


Inorganic silicon compounds may be acute inhalation irritants. Prolonged inhalation may cause pulmonary fibrosis known as silicosis.


Acute Effects:


Inhalation: May cause irritation to the respiratory system.

Ingestion: No acute health effects recorded.

Skin: May cause abrasive irritation.

Eye: May cause abrasive irritation.


Chronic Effects: Inhalation: May cause pneumoconiosis, pulmonary fibrosis and silicosis. No other chronic health effects recorded.


Target Organs: May affect the respiratory system.


Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders.

 

Carcinogenicity: NTP: No           IARC: No          OSHA: Yes


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 if symptoms persist.

INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek medical attention if symptoms persist. 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 plenty of 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 (Material to Avoid): Strong acids and bases, oxidizing agents.

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.

Waste Disposal Method: Dispose of in accordance with local, state and federal regulations.



VIII. SPECIAL PROTECTION INFORMATION


Respiratory Protection: NIOSH approved dust respirator.

Ventilation: Use local exhaust to maintain concentration at low exposure levels. General exhaust is recommended.

Other Protective Equipment: Protective gear suitable to prevent contamination.



IX. SPECIAL PRECAUTIONS


Precautions to Be Taken in Handling and Storing: Store in tightly sealed container. Store in cool, dry area. Wash thoroughly after handling.

Other Precautions: Avoid contact with eyes and inhalation of dust.

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. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
