IV. FIRE AND EXPLOSION HAZARDS DATA

Flash Point: N/A

Autoignition Temperature: N/A

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

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

Special Firefighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. If without risk remove material from fire area.

Unusual Fire & Explosion Hazard: In case of fire calcium boride may emit toxic calcium oxide and boron oxide fumes. On contact with moisture, acid or acid fumes, calcium boride may evolve boron hydrides which may be toxic and flammable.

V. HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of calcium boride have not been thoroughly investigated and recorded.

Calcium compounds should be considered toxic only when they contain toxic components or as calcium oxide or hydroxide.

Boron compounds are very toxic and therefore considered an industrial poison. Boron affects the central nervous system. Boron poisoning causes depression of the circulation, persistent vomiting and diarrhea, followed by profound shock and coma. The temperature becomes subnormal and a scarlatina from rash may cover the entire body.

Acute Effects:

Inhalation: May cause irritation to the respiratory system.

Ingestion: No acute health effects recorded.

Skin: May cause mild irritation.

Eye: May cause mild irritation.

Chronic Effects:

Inhalation: No chronic health effects recorded.

Ingestion: May cause gastrointestinal disorders.

Skin: May cause dermatitis.

Eye: No chronic health effects recorded.

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

Carcinogenicity: NTP: No           IARC: No          OSHA: No         EPA: 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.

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 with mild soap and water, seek medical attention.

EYES: Immediately flush eyes, including under eyelids, with large amounts of water for at least 15 minutes. Seek medical attention immediately.

VI. REACTIVITY DATA

Stability: Stable

Conditions to Avoid: Exposure to moisture.

Incompatibility (Material to Avoid): Water, acids, acid fumes.

Hazardous Decomposition Products: Metal and metal oxide fumes, boron hydrides.

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. Sweep or 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 dust respirator

Ventilation: Handle in a dry, controlled atmosphere. Use local exhaust to maintain concentration of exposure at low levels. General exhaust is recommended.

Protective Gloves: Rubber gloves

Eye Protection: Safety goggles

Other Protective Clothing or Equipment: Lab coat and apron, flame and chemical resistant coveralls, as needed to prevent contact.

IX. SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage: Handle in glove bag or box with dry inert atmosphere. Keep container tightly closed. Store in a cool, dry well-ventilated area. Wash thoroughly after use.

Other Precautions: Avoid breathing dusts, vapors or mist. Avoid contact with eyes. Store in a dry place away from excessive heat. Avoid contact with water or moisture. Reseal containers immediately after use.

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 the work area. Wash thoroughly before eating and smoking. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and hygienic facilities for washing.
