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.
