Section 1: Product Identification Chemical Name:Lanthanum (III) sulfide (99.9%-La) (REO) CAS Registry Number:12031-49-1 Formula:La2S3 EINECS Number:234-752-8 Chemical Family:metal chalcogenides Synonym:none
Section 2: Composition and Information on Ingredients IngredientCAS NumberPercentACGIH (TWA)OSHA (PEL) Title Compound12031-49-1100%no datano data Section 3: Hazards Identification Emergency Overview:Forms highly toxic gas on exposure to acids or stomach fluids. Irritating to skin, eyes, and respiratory tract. Primary Routes of Exposure:Ingestion, inhalation, skin and eyes Eye Contact:Causes moderate irritation of the eyes. Skin Contact:Causes slight irritation of the skin. Inhalation:Inhalation of dust will lead to irritation of the respiratory tract. Hydrogen sulfide gas, if formed, is poisonous. Ingestion:Gastric juices may cause release of toxic hydrogen sulfide. Irritating to skin, eyes and respiratory tract. Hydrogen sulfide gas may cause painful conjunctivitis, headache, Acute Health Affects: nausea, dizziness, pulmonary edema and possible death. Chronic Health Affects:No information available on long-term chronic effects. 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:no data Explosion Limits:no data Extinguishing Medium:carbon dioxide or dry powder 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 irritating fumes of hydrogen sulfide and sulfur dioxide. Decomposion Products: Dust may form explosive mixtures with air. Contact with acids gives off hydrogen sulfide, a toxic and Unusual Fire or Explosion Hazards: flammable gas. SECTION 6: Accidental Release Measures In the case of a spill, the fine powder should be covered with dry sodium carbonate or dolomite in order to Spill and Leak Procedures: reduce the formation of dust. Sweep up the mixture. SECTION 7: Handling and Storage Store in a tightly sealed container. Exposure to the atmosphere may lead to release of toxic hydrogen sulfide Handling and Storage: gas. Empty containers may retain product residues that evolve toxic gases. 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 appropriate chemical resistant gloves and protective clothing. Ventilation:If possible, handle the material in an efficient fume hood. If ventilation is not available a respirator should be worn. The use of a respirators requires a Respirator Respirator: Protection Program to be in compliance with 29 CFR 1910.134. Ventilation:If possible, handle the material in an efficient fume hood. Additional Protection:No additional protection required. SECTION 9: Physical and Chemical Properties Color and Form:yellow powder Molecular Weight:374.01 Melting Point:2100-2150° Boiling Point:no data Vapor Pressure:no data Specific Gravity:4.911 Odor:odor of sulfur Solubility in Water:insoluble SECTION 10: Stability and Reactivity Stability:air and moisture stable Hazardous Polymerization:no hazardous polymerization Conditions to Avoid:Contact of dust cloud with an ignition source. Incompatibility:oxidizing agents and mineral acids Decomposition Products:hydrogen sulfide, sulfur dioxide, and metal oxides. SECTION 11: Toxicological Information RTECS Data:No information available in the RTECS files. Carcinogenic Effects:no data Mutagenic Effects:no data Tetratogenic Effects:no data SECTION 12: Ecological Information Ecological Information:No information available SECTION 13: Disposal Considerations Disposal:Dispose of according to local, state and federal regulations.
