Synonym:  Potassium Permanganate, Biotech Grade Chemical Name:  Potassium Permanganate Chemical Formula:  KMnO4 Contact Information:Sciencelab.com, Inc. 14025 Smith Rd.Houston, Texas 77396US Sales: 1-800-901-7247 International Sales: 1-281-441-4400 Order Online: ScienceLab.com CHEMTREC (24HR Emergency Telephone), call: 1-800-424-9300 International CHEMTREC, call:  1-703-527-3887 For non-emergency assistance, call:  1-281-441-4400 Section 2: Composition and Information on Ingredients Composition:NameCAS #% by Weight Potassium permanganate7722-64-7100 Toxicological Data on Ingredients:  Potassium permanganate, Biotech: ORAL (LD50): Acute: 1090 mg/kg [Rat]. 2157 mg/kg[Mouse]. Section 3: Hazards Identification Potential Acute Health Effects: Hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Slightly hazardous in case ofskin contact (permeator). Possibly corrosive to eyes and skin. The amount of tissue damage depends on length of contact.Eye contact can result in corneal damage or blindness. Skin contact can produce inflammation and blistering. Inhalation ofdust will produce irritation to gastro-intestinal or respiratory tract, characterized by burning, sneezing and coughing. Severeover-exposure can produce lung damage, choking, unconsciousness or death. Prolonged exposure may result in skin burnsand ulcerations. Over-exposure by inhalation may cause respiratory irritation. Potential Chronic Health Effects: CARCINOGENIC EFFECTS: Not available. MUTAGENIC EFFECTS: Mutagenic for bacteria and/or yeast. TERATOGENICEFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available. The substance may be toxic to kidneys, liver, skin,central nervous system (CNS). Repeated or prolonged exposure to the substance can produce target organs damage.Repeated exposure of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce localskin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage.  p. 2 Section 4: First Aid Measures Eye Contact: Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15minutes. Cold water may be used. Get medical attention immediately. Skin Contact: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothingand shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash clothing before reuse. Thoroughly cleanshoes before reuse. Get medical attention immediately. Serious Skin Contact: Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medicalattention. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medicalattention. Serious Inhalation: Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. Ifbreathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. WARNING: It maybe hazardous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infectious orcorrosive. Seek immediate medical attention. Ingestion: Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconsciousperson. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar,tie, belt or waistband. Serious Ingestion:  Not available. Section 5: Fire and Explosion Data Flammability of the Product:  Non-flammable. Auto-Ignition Temperature:  Not applicable. Flash Points:  Not applicable. Flammable Limits:  Not applicable. Products of Combustion:  Not available. Fire Hazards in Presence of Various Substances:  organic materials, metals, combustible materials Explosion Hazards in Presence of Various Substances: Risks of explosion of the product in presence of mechanical impact: Not available. Risks of explosion of the product inpresence of static discharge: Not available. Explosive in presence of organic materials, of metals. Fire Fighting Media and Instructions:  Not applicable. Special Remarks on Fire Hazards: Spontaneously flammable on contact with ethylene glycol. Potassium Permanganate being conveyed through propylene tubeignited the tube. When solid hydroxylamine is brought into contact with solid potassium permanganate, there is producedimmediately a with flame. Potassium permanganate decomposes hydrogen trisulfide so rapidly that sufficient heat is liberatedto ignite the trisulfide. When Antimony or arsenic and solid potassium permanganate are ground together, the metals ignite. Special Remarks on Explosion Hazards: Take care in handling as explosions may occur if it is brought in contact with organic or other readily oxidizable substances,either in solution or in dry state. Explosive in contact with sulfuric acid or hydrogen peroxide. Potassium permanganate +acetic acid or acetic anhydride can explode if permanganate is not kept cold. Explosions can occur when permanganatescome on contact with benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, or oganic matter. Contact with glycerol  p. 3may produce explosion. Crystals of potassium permanganate explode vigorously when ground with phosphorous. A mixtureof .5% potassium permanganate + ammonium nitrate explosive caused an explosion 7 hrs. later. Addition of Potassiumpermanganate + dimethylformamide to give a 20% solution led to an explosion after 5 min. During a preparation of chlorineby addition of the concentrated acid (Hydrochloric acid) to solid potassium permanganate, a sharp explosion occurred on oneoccasion. Section 6: Accidental Release Measures Small Spill:  Use appropriate tools to put the spilled solid in a convenient waste disposal container. Large Spill: Oxidizing material. Corrosive solid. Stop leak if without risk. Do not get water inside container. Avoid contact with acombustible material (wood, paper, oil, clothing...). Keep substance damp using water spray. Do not touch spilled material.Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Call for assistanceon disposal. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and withlocal authorities. Section 7: Handling and Storage Precautions: Keep away from heat. Keep away from sources of ignition. Keep away from combustible material. Do not ingest. Do notbreathe dust. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek medical adviceimmediately and show the container or the label. Avoid contact with skin and eyes. Keep away from incompatibles such asorganic materials, metals, acids. Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area. Separate from acids, alkalies, reducing agentsand combustibles. See NFPA 43A, Code for the Storage of Liquid and Solid Oxidizers. Section 8: Exposure Controls/Personal Protection Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommendedexposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminantsbelow the exposure limit. Personal Protection: Splash goggles. Synthetic apron. Vapor and dust respirator. Be sure to use an approved/certified respirator or equivalent.Gloves. Personal Protection in Case of a Large Spill: Splash goggles. Full suit. Vapor and dust respirator. Boots. Gloves. A self contained breathing apparatus should be used toavoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handlingthis product. Exposure Limits: TWA: 5 Consult local authorities for acceptable exposure limits.
