*2 The letter M means transition metal and candidates of M are Co, Mn and Ni. One compound includes one ore more of these metals and one product includes one or more of the compounds. The letter m and n means the number of atoms. 3. HAZARDS IDENTIFICATION For the battery cell, chemical materials are stored in a hermetically sealed metal case, designed to withstand temperatures and pressures encountered during normal use. As a result, during normal use, there is no physical danger of ignition or explosion and chemical danger of hazardous materials' leakage. However, if exposed to a fire, added mechanical shocks, decomposed, added electric stress by miss-use, the gas release vent will be operated. The battery cell case will be breached at the extreme, hazardous materials may be released. Moreover, if heated strongly by the surrounding fire, acrid gas may be emitted. .Most important hazard and effects Human health effects: Inhalation: The steam of the electrolyte has an anesthesia action and stimulates a respiratory tract. Skin contact: The steam of the electrolyte stimulates a skin. The electrolyte skin contact causes a sore and stimulation on the skin. Eye contact: The steam of the electrolyte stimulates eyes. The electrolyte eye contact causes a sore and stimulation on the eye. Especially, substance that causes a strong inflammation of the eyes is contained. Environmental effects: Since a battery cell remains in the environment, do not throw out it into the environment. .Specific hazards: If the electrolyte contacts with water, it will generate detrimental hydrogen fluoride. Since the leaked electrolyte is inflammable liquid, do not bring close to fire. Product name: Lithium ion battery cell Reference number: SDS-IBT-00026 Establishment / Revision: Dec. 3, 2010 2/6 4. FIRST-AID MEASURES Spilled internal cell materials .Inhalation: Make the victim blow his/her nose, gargle. Seek medical attention if necessary. .Skin contact: Remove contaminated clothes and shoes immediately. Wash extraneous matter or contact region with soap and plenty of water immediately. .Eye contact: Do not rub one’s eyes. Immediately flush eyes with water continuously for at least 15 minutes. Seek medical attention immediately. A battery cell and spilled internal cell materials .Ingestion: Make the victim vomit. When it is impossible or the feeling is not well after vomiting, seek medical attention. 5. FIRE-FIGHTING MEASURE .Suitable extinguishing media: Plenty of water, carbon dioxide gas, nitrogen gas, chemical powder fire extinguishing medium and fire foam. .Specific hazards: Corrosive gas may be emitted during fire. .Specific methods of fire-fighting: When the battery burns with other combustibles simultaneously, take fireextinguishing method which correspond to the combustibles. Extinguish a fire from the windward as much as possible. .Special protective equipment for firefighters: Respiratory protection: Respiratory equipment of a gas cylinder style or protection-agains...
