Section 1: Product Identification Chemical Name:Strontium hydride (99.5%-Sr) CAS Registry Number:13598-33-9 Formula:SrH2 EINECS Number:237-065-1 Chemical Family:metal hydride Synonym:Strontium dihydride
Section 2: Composition and Information on Ingredients IngredientCAS NumberPercentACGIH (TWA)OSHA (PEL) Title compound13598-33-9100%no datano data Section 3: Hazards Identification Irritating to skin, eyes and respiratory tract. Inhalation of fine dust will cause severe irritation or caustic burns to Emergency Overview: respiratory system, skin and eyes. Primary Routes of Exposure:Contact with skin and eyes. Inhalation of dust Eye Contact:Corrosive to eyes. May cause severe eye damage. Skin Contact:Causes severe irritation and chemical burns to the skin. Inhalation:Harmful by inhalation. Dust causes severe irritation to the nose, mucous membranes and respiratory tract. Ingestion:Harmful if swallowed. Material reacts with moisture causing chemical burns to the mouth and throat. With moisture or human contact, hydride rapidly forms caustic alkali hydroxide with evolution of heat. Severe Acute Health Affects: irritation or chemical burns will result. 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 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:no data Autoignition Temperature:no data Explosion Limits:no data Extinguishing Medium:Class D metal fire agent, dry salt, limestone or sand. 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, burning hydride may produce alkaline fumes. Decomposion Products: Unusual Fire or Explosion Hazards: Flammable solid. Dust may form explosive mixtures with air. Evolves flammable hydrogen with water. SECTION 6: Accidental Release Measures Remove sources of ignition. Do not raise dust. Mix with vermiculite or other suitable dry adsorbent and sweep Spill and Leak Procedures: up. SECTION 7: Handling and Storage Store material in a tightly sealed container under an inert atmosphere of nitrogen or argon. Keep away from Handling and Storage: heat and moisture. 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. Ventilation:Material may form a fine dust. 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:-60mesh gray pwdr. Molecular Weight:89.64 Melting Point:no data Boiling Point:no data Vapor Pressure:no data Specific Gravity:no data Odor:none Solubility in Water:reacts with water SECTION 10: Stability and Reactivity Stability:moisture sensitive Hazardous Polymerization:no hazardous polymerization Conditions to Avoid:contact with moisture and mineral acids. Reaction with mineral acids can release flammable hydrogen gas. Incompatibility:mineral acids, water, oxidizing agents, alcohols, carbonyl compounds and halogens Decomposition Products:hydrogen (in presence of moisture) and strontium oxide. 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. SECTION 14: Transportation Shipping Name (CFR):Metal hydrides, Water-reactive, N.O.S. Hazard Class (CFR):4.3 Additional Hazard Class (CFR):NA Packaging Group (CFR):I UN ID Number (CFR):UN# 1409 Shipping Name (IATA):Metal hydrides, Water-reactive, N.O.S.
