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.
žMost 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.
žSpecific 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.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION
žEngineering measures:
No engineering measure is necessary during normal use. In case of internal cell materials' leakage,
operate the local exhaust or improve ventilation.

10. STABILITY AND REACTIVITY
žStability: Stable under normal use
žHazardous reactions occurring under specific conditions
žConditions to avoid: When a battery cell is exposed to an external short-circuit, crushes, deformation,
high temperature above 100 degree C, it will be the cause of heat generation and ignition. Direct
sunlight and high humidity.
žMaterials to avoid: Conductive materials, water, seawater, strong oxidizers and strong acids.
žHazardous decomposition products: Acrid or harmful gas is emitted during fire.

11. TOXICOLOGICAL INFORMATION
There is no available data on the product itself. The information of the internal cell materials is as follows.
Lithium metal oxidate –Li(Mn-Co-Ni)O2
žAcute toxicity: No applicable data.
Reference cobalt: LDLo, oral - Guinea pig 20mg/kg
manganese: LD50, oral - Guinea pig 9000mg/kg
nickel: LDLo, oral - Guinea pig 5mg/kg
žLocal effects: Unknown.
žSensitization:
The nervous system of respiratory organs may be stimulated sensitively.
žChronic toxicity/Long term toxicity:
By the long-term inhalation of coarse particulate or vapor of cobalt, it is possible to cause the serious
respiratory-organs disease. Skin reaction or a lung disease for allergic or hypersensitive person may be
caused.
By the long-term or repetitive inhalation of coarse particulate of Manganese Oxide (MnO2), lungs and
nervous system may be affected; bronchitis, pneumonia, nerve disease or nerve mental disorder
(manganese poisoning) may be caused.
Nickel Compounds belong to the 1st group of the carcinogen in the IARC category (substance which
has carcinogenic to man).
žSkin causticity: Although it is very rare, the rash of the skin and allergic erythema may result.
Aluminum
žLocal effects: Aluminum itself has no toxicity. When it goes into a wound, dermatitis may be caused.
žChronic toxicity/Long term toxicity: By the long-term inhalation of coarse particulate or fume, it is possible
to cause a lung damage (aluminum lungs).
Graphite
žAcute toxicity: Unknown.
žLocal effects: When it goes into one’s eyes, it stimulates one’s eyes; conjunctivitis, thickening of corneal
epithelium or edematous inflammation palpebra may be caused.
žChronic toxicity/Long term toxicity:
Since the long-term inhalation of high levels of graphite coarse particulate may become a cause of a
lung disease or a tracheal disease.
žCarcinogenicity:
Graphite is not recognized as a cause of cancer by research organizations and natural toxic substance
research organizations of cancer.
Copper
žAcute toxicity:
60-100mg sized coarse particulate causes a gastrointestinal disturbance with nausea and inflammation.
TDLo, hypodermic - Rabbit 375mg/kg
žLocal effects:
Coarse particulate stimulates a nose and a tracheal.
When it goes into one’s eyes, the symptom of the reddening and the pain is caused.
