2.HAZARDS IDENTIFICATION
・Most important hazard and effects
For the battery cell, chemical materials are stored in a hermetically sealed metal case, designed to withstandtemperatures 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, thegas 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, thecornea 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.

4.FIRST-AID MEASURESInternal 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 MEASURESInternal cell materials, such as electrolyte leaked from battery cell, are carefully dealt with according to thefollowings.
・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 ismoved 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 notsoak cells in water and seawater. Do not expose to strong oxidizers. Do not give a strong mechanicalshock or throw down. Never disassemble, modify or deform. Do not connect the positive terminal to
the negative terminal with electrically conductive material. In the case of charging, use only dedicatedcharger or charge according to the conditions specified by FDK.
