Lithium Ion Rechargeable Battery Pack

SECTION 2: Hazards identification

Do not short circuit, puncture, incinerate, crush, immerse, force discharge or expose to temperatures above the declared operating temperature range of the product. Risk of fire or explosion. The batteries described in this Product Safety Data Sheet are sealed units, which are not hazardous when used according to the recommendations of the manufacture. Under normal conditions of use, the electrode materials and electrolyte they contain are not exposed to the outside, provided the battery integrity is maintained and seals remain intact. Risk of exposure only in case of abuse (mechanical, thermal, electrical) which leads to the activation of safety valves or the rupture of the battery containers. Electrolyte leakage or battery vent explosion/fire may follow, depending upon the circumstances. SECTION 4- FIRST-AID MEASURES Under normal conditions of use, the battery is hermetically sealed. Ingestion: Swallowing a battery can be harmful. Contents of an open battery can cause serious chemical burns of mouth, esophagus, and gastrointestinal tract. If battery or open battery is ingested, do not induce vomiting or give food or drink. Seek medical attention immediately. Inhalation: Contents of an open battery can cause respiratory irritation. Inhalation of vapors may cause irritation of the upper respiratory tract and lungs. Provide fresh air and seek medical attention. Skin Absorption: Ethylene carbonate, diethyl carbonate and dimethyl carbonate may be absorbed through the skin causing localized inflammation. Skin Contact: Contents of an open battery can cause skin irritation and/or chemical burns. Remove contaminated clothing and wash skin with soap and water. If a chemical burn occurs or if irritation persists, seek medical attention. Eye Contact: Contents of an open battery can cause severe irritation and chemical burns. Immediately flush eyes thoroughly with water for at least 15 minutes, lifting upper and lower lids, until no evidence of the chemical remains. Seek medical attention. Note: Acetylene black and cobalt compounds are listed as possible carcinogens by the International Agency for Research on Cancer (IARC). 1 SECTION 5- FIRE-FIGHTING MEASURES If fire or explosion occurs when battery are on charge, shut off power to charger. In case of fire where lithium ion battery is present, flood the area with water. If any battery is burning, water may not extinguish them, but will cool the adjacent battery and control the spread of fire. CO2, dry chemical, and foam extinguishers are preferred for small fires, but also may not extinguish burning lithium ion battery. Burning battery will burn out. Virtually all fires involving lithium ion battery can be controlled with water. When water is used, however, hydrogen gas may be evolved which can form an explosive mixture with air. LITHX (powdered graphite) or copper powder fire extinguishers, sand, dry ground dolomite or soda ash may also be used. These materials act as smothering agents. Fire fighters should wear self-contained breathing apparatus. Burning lithium ion battery can produce toxic fumes including HF, oxides of carbon, aluminum, lithium, copper, and cobalt. Volatile phosphorus pentafluoride may form at a temperature above 230º Fahrenheit. SECTION 6- SPECIAL PROTECTION INFORMATION: Ventilation Requirements: Not necessary under normal conditions. Respiratory Protection: Not necessary under normal conditions. Eye Protection: Not necessary under normal conditions. Wear safety glasses with side shields if handling an open or leaking battery. Gloves: Not necessary under normal conditions. Use neoprene or natural rubber gloves if handling an open or leaking battery. Open Battery Storage: Battery should not be opened. Should a cell become disassembled, the electrode should be stored in a fireproof cabinet, away from combustibles. SECTION 7- HANDLING & STORAGE Handling: Do not expose the battery to excessive physical shock or vibration. Short-circuiting should be avoided; however, accidental short-circuiting for a few seconds will not seriously affect the battery cells. Prolonged short circuits will cause the battery cells to rapidly lose energy, could generate enough heat to burn skin. Sources of short circuits include jumbled battery in bulk containers, coins, metal jewelry, metal covered tables, or metal belts used for assembly of battery in devices. To minimize risk of short-circuiting, the battery case should be not be broken. Do not disassemble or deform the battery.Should an individual cell within a battery become ruptured, do not allow contact with water. Storage: Store the battery at ambient temperature in clean environment without chemical vapor nor excessive humidity and temperature above 80℃ degree can result in loss of battery performance, leakage, or rust. Do not expose the battery to open flames. SECTION 8- EXPOSURE CONTROL/PERSONAL PROTECTION
