Section 1: Product Identification Chemical Name:Germanium (II) iodide (99.99+%-Ge) PURATREM CAS Registry Number:13573-08-5 Formula:GeI2 EINECS Number:236-998-1 Chemical Family:metal halide Synonym:Germanium diiodide
Section 2: Composition and Information on Ingredients IngredientCAS NumberPercentACGIH (TWA)OSHA (PEL) Title Compound13573-08-5100%no datano data Section 3: Hazards Identification Severe irritant to skin, eyes and respiratory tract. Material hydrolyzes in contact with moisture releasing Emergency Overview: hydroiodic acid and under some conditions corrosive hydrogen iodide vapors. Primary Routes of Exposure:Ingestion, inhalation, skin, eyes Eye Contact:Causes severe irritation to the eyes. Skin Contact:Causes severe irritation of the skin with redness, pain, itching, pimples, boils, hives and blisters. Forms hydroiodic acid in the presence of moisture. Inhalation of vapors leads to irritation of the respiratory Inhalation: tract. Ingestion:Severe irritation of the Gastrointestinal system may occur. Acute Health Affects:Irritating to skin, eyes and respiratory tract. May cause dyspnea (breathing difficulty), and pulmonary edema. Chronic ingestion of iodides may produce iodism. Symptoms include skin rash, running nose, headache and Chronic Health Affects: irritation of mucous membranes. 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 involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained Special Fire Fighting Procedures: breathing apparatus and full protective clothing. Hazardous Combustion andIf involved in a fire this material may emit corrosive hydrogen fluoride 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 can be mixed with powdered sodium bicarbonate, lime, or calcium carbonate Spill and Leak Procedures: and swept up. SECTION 7: Handling and Storage Store material in a tightly sealed bottle away from moisture. If possible, handle material in an efficient fume Handling and Storage: hood. Prolonged exposure to the atmosphere may lead to degradation of the product. 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.
