4 FIRST AID MEASURES
General Measures: No special requirements.
INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek medical attention.
INGESTION: Rinse mouth with water. Do not induce vomiting. Seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing, brush material off skin, wash affected area with soap and water. Seek medical attention.
EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention.
Most Important Symptoms/Effects, Acute and Delayed: May cause irritation. See section 11 for more information.
Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.
5 FIREFIGHTING MEASURES
Extinguishing Media: Use Class D dry powder extinguishing agent.
Unsuitable Extinguishing Media: Do not use water.
Specific Hazards Arising from the Material: Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source, is a weak dust explosion hazard. May emit toxic tellurium oxide fumes under fire conditions.
Special Protective Equipment and Precautions for Firefighters: Full face, self-contained breathing apparatus and full protective clothing when necessary.
6 ACCIDENTAL RELEASE MEASURES
Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes. Eliminate all sources of ignition.
Methods and Materials for Containment and Cleaning Up: Avoid raising dust. Scoop up or vacuum using a vacuum system equipped with a HEPA filter. Place in properly labeled closed containers.
Environmental Precautions: Do not allow to enter drains or to be released to the environment.
7 HANDLING AND STORAGE
Precautions for Safe Handling: Avoid high temperatures. If your process involves heating or melting tellurium use all precautions to avoid breathing fumes. Provide adequate ventilation if dusts or fumes are created. Avoid breathing dusts. Avoid contact with skin and eyes. See section 8 for information on personal protection equipment.
Conditions for Safe Storage: Store in a cool, dry, well-ventilated area. Store in a tightly-closed container away from sources of heat. Protect from acids. See section 10 for more information on incompatible materials.
8 EXPOSURE CONTROLS AND PERSONAL PROTECTION
Exposure Limits: Tellurium (Tellurium compounds, as Te)
OSHA/PEL: 0.1 mg/m3
ACGIH/TLV: 0.1 mg/m3
Engineering Controls: Ensure adequate ventilation to maintain exposures below occupational limits. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. 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.
Respiratory Protection: When potential exposures are above the occupational limits, approved respirators must be used.
Eye Protection: Safety glasses
Skin Protection: Wear impermeable gloves, protective work clothing as necessary.

11 TOXICOLOGICAL INFORMATION
Likely Routes of Exposure: Inhalation, skin, eyes.
Symptoms of Exposure: Inhalation of elemental tellurium dusts may cause irritation and congestion.
Acute and Chronic Effects: Elemental tellurium dusts may cause irritation of the respiratory tract. Other symptoms include metallic taste, loss of appetite, dryness of the mouth, suppression of sweating and garlic odor of breath, sweat and urine. Tellurium compounds are more toxic than metallic tellurium.
Acute Toxicity: LD50 oral - rat - >5000 mg/kg
