2.HAZARDS IDENTIFICATION
• Most important hazard and effects 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 misuse, 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 or harmful fume may be emitted. Human health effects: Inhalation: The electrolyte inhalation affects the respiratory tract membrane and the lungs. Fume may cause a cough, chest pain and dyspnea. Bronchitis and pneumonia  may occur. Possibly could be carcinogen. Skin contact: The electrolyte skin contact affects the skin seriously and may cause dermatitis. Eye contact: The electrolyte leaked from the battery cell is strong alkali. When it goes into an eye, the cornea may be affected and it may lead to blindness. Ingestion: The electrolyte ingestion irritates the mouth and the throat seriously results in vomiting, nausea, hematemesis, stomach pains and diarrhea. Environmental effects: Since a battery cell remains in the environment, do not throw out it into the environment. • Specific hazards : As previously described.

4.FIRST-AID MEASURES
Internal cell materials of an opened battery cell • Inhalation : Cover the victim in a blanket, move to the place of fresh air and keep quiet. Seek medical attention immediately. When dyspnea (breathing difficulty) or asphyxia (breath-hold), give artificial respiration immediately. • Skin contact : Remove contaminated clothes and shoes immediately. Wash the adherence or contact region with soap and plenty of water. Seek medical attention immediately. • Eye contact : Immediately flush eyes with water continuously for at least 15 minutes. Seek medical attention immediately. A battery cell and internal cell materials of an opened battery cell • Ingestion : Do not induce vomiting. Seek medical attention immediately.
5.FIRE-FIGHTING MEASURE
Although a battery cell is not flammability, in case of fire, move it to the safe place quickly. The following measures are taken when it cannot be moved. • Suitable extinguishing media: Dry sand, chemical powder fire extinguishing medium. • Specific hazards: Acrid or harmful fume is emitted during fire. • Special protective equipment for firefighters : Protective equipment written in Section 8.
6.ACCIDENTAL RELEASE MEASURES
Internal cell materials, such as electrolyte leaked from battery cell, are carefully dealt with according to the followings. • Personal precautions : Forbid unauthorized person to enter. Remove leaked materials with protective equipment written in Section 8. • Environmental precautions: Do not throw out into the environment. • Method of recovery and neutralization : Dilute the leaked electrolyte with water and neutralize with diluted sulfuric acid. The leaked solid is moved to a container. The leaked place is fully flushed with water.
7.HANDLING AND STORAGE
• Handling Technical measures Prevention of user exposure: Not necessary under normal use. Prevention of fire and explosion: Not necessary under normal use. Precaution for safe handling: Do not damage or remove the external tube. Specific safe handling advice: Never throw out cells in a fire or expose to high temperatures. Do not soak cells in water and seawater. Do not expose to strong oxidizers. Do not give a strong mechanical shock or throw down. Never disassemble, modify or deform. Do not connect the positive terminal to the negative terminal with electrically conductive material.
