Section 1: Product Identification Chemical Name:Trimethylindium, elec. gr. (99.999%-In) PURATREM **S STEEL CYL EXTRA** **Can be ampouled** CAS Registry Number:3385-78-2 Formula:(CH3)3In EINECS Number:222-200-9 Chemical Family:metal alkyl Synonym:Indium, trimethyl
Section 2: Composition and Information on Ingredients IngredientCAS NumberPercentACGIH (TWA)OSHA (PEL) Title Compound3385-78-2100%0.1mg/m3 (as In)no data Section 3: Hazards Identification Pyrophoric material. Ignites spontaneously on contact with air causing thermal burns. Burning solid/liquid Emergency Overview: clings to clothing and skin. Primary Routes of Exposure:Inhalation, skin, eyes Eye Contact:Dust causes severe thermal burns to eyes. Irritating fumes. Skin Contact:Solid ignites. Hard to extinguish burning gel on the skin and clothing. White fumes from burning solid irritating to the tissues of the nose, mucous membranes, and respiratory tract. Inhalation: Ingestion:Ingestion of burning solid is unlikely. Solid is pyrophoric and bursts into flames causing severe thermal burns. Dense white smoke is irritating to Acute Health Affects: skin, eyes and respiratory tract. Chronic Health Affects:No information 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 immediately with water. Remove contaminated clothing if necessary. Seek medical Skin Exposure: assistance if 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:-1°F Autoignition Temperature:pyrophoric Explosion Limits:no data Extinguishing Medium:carbon dioxide, dry powder or foam 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 indium oxide. Decomposion Products: Unusual Fire or Explosion Hazards: Pyrophoric material. Material will ignite spontaneously in contact with air. SECTION 6: Accidental Release Measures The material will ignite spontaneously in air. Burning material may release toxic fumes. Leave the area unless Spill and Leak Procedures: fitted with a self-contained breathing apparatus. Smother fire with dry powder. Do not use water. SECTION 7: Handling and Storage Store cold. Handle and store the material under an inert atmosphere of nitrogen or argon. Prepare for the Handling and Storage: possibility of fire in transfer lines and containers after use. Keep away from heat. 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. Consult with glove manufacturer to determine the proper type of glove. Ventilation: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. Ventilation:Handle the material in an efficient fume hood. Additional Protection:Wear a full face shield, lab apron and suitable gloves. SECTION 9: Physical and Chemical Properties Color and Form:white xtl. Molecular Weight:159.92 Melting Point:88° Boiling Point:136°C Vapor Pressure:no data Specific Gravity:1.568 Odor:none Solubility in Water:reacts vigorously with water SECTION 10: Stability and Reactivity Stability:heat sensitive, moisture sensitive, pyrophoric Hazardous Polymerization:no hazardous polymerization Conditions to Avoid:contact with air Incompatibility:oxygen, halogens, oxidizing agents and water Decomposition Products:carbon dioxide, carbon monoxide, indium oxide, organic fumes.
