Section 2: Composition and Information on Ingredients IngredientCAS NumberPercentACGIH (TWA)OSHA (PEL) Title Compound12002-99-2100%0.1mg/m3 (as Te)0.1mg/m3 (as Te) Section 3: Hazards Identification May be harmful if swallowed. Chronic exposure may lead to a skin discoloration. Inhalation of dust may cause Emergency Overview: garlic odor of breath, metallic taste, sleepiness, headache and nausea. Primary Routes of Exposure:Ingestion , inhalation, skin, and eyes. Eye Contact:May be a mild to moderate irritant to the eyes. Skin Contact:May cause slight irritation of the skin. Inhalation of dust can lead to irritation of the respiratory tract garlic odor of breath, metallic taste, sleepiness, Inhalation: headache and nausea. Ingestion of only moderate amounts of tellurium may lead to nausea, vomiting, bloody diarrhea, weakness, Ingestion: and death. Acute Health Affects:May cause garlic odor of breath, metallic taste, sleepiness, headache and nausea. Long term exposure to silver and silver salts can lead to the condition known as argyria-a general gray Chronic Health Affects:pigmentation of the skin and mucous membranes. Prolonged exposure to tellurium may cause drowsiness and loss of appetite. NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce Ingestion: vomiting only if directed by medical personnel. SECTION 5: Fire Fighting Measures Flash Point:not applicable Autoignition Temperature:none Explosion Limits:none Extinguishing Medium:none required If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure Special Fire Fighting Procedures: self- contained breathing apparatus and full protective clothing. Hazardous Combustion andIf involved in a fire this material may emit toxic fumes. Decomposion Products: Unusual Fire or Explosion Hazards: No unusual fire or explosion hazards. SECTION 6: Accidental Release Measures To avoid raising dust, small spills may be mixed with diatomaceous earth, sand, vermiculite, or other suitable Spill and Leak Procedures: inert material and swept up. SECTION 7: Handling and Storage Handling and Storage:Store in a cool, dry place in a tightly sealed container. SECTION 8: Exposure Controls and Personal Protection Eye Protection:Always wear approved safety glasses when handling a chemical substance in the laboratory. Skin Protection:Wear protective clothing and gloves. Ventilation:Material may form a fine dust. If possible, handle the material in an efficient fume hood. If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Respirator: Protection Program to be in compliance with 29 CFR 1910.134.
