2. Hazards Identification

For the battery cell, chemical materials are stored in a hermetically sealed metal or metal

laminated plastic case, designed to withstand temperature and pressure 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, acid gas may be emitted.

GHS Classification : Not available

(This product is outside the scope of GHS system since it’s considered as an “article”.)

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.

Precautions for human body :Remove spilled materials with protective equipment (protective glasses and protective gloves). Do not inhale the gas as much as possible. Moreover, avoid touching with as much as possible. Environmental precautions :Do not throw out into the environment. Method of cleaning up :The spilled solids are put into a container. The leaked place is wiped off with dry cloth. Prevention of secondary hazards :Avoid re-scattering. Do not bring the collected materials close to fire. 7.

10. Stability and Reactivity Stability :Stable under normal use Hazardous reactions occurring under specific conditions: Conditions 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. Materials to avoid :Conductive materials, water, seawater, strong oxidizers and strong acids.
