Rechargeable Lithium-Ion battery pack

SECTION 2: Hazards identification

The cells inside the battery pack store the chemical materials 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 and the product is safe. However, mishandling or exposure to a fire, abnormal mechanical shock, decomposition or added electric stress by misuse can result in gas release, flaming, acrid gas emission or electrolyte leakage as the vents operate.

2.1 Classification of the substance or mixture

No applicable labelling Most important hazard and effects

Potential health effects

Inhalation: the vapour of the electrolyte has an anaesthetic effect and stimulates the respiratory tract. Skin contact: the vapour of the electrolyte stimulates the skin. An electrolyte/skin contact can cause sores and stimulation of the skin. Eye contact: the vapour of the electrolyte irritates eyes. An electrolyte-eye contact can cause sores and irritation of the eye. In particular, substances that cause a strong inflammation of the eyes are contained within.

Environmental effects

A battery pack is to be disposed of according to regulatory procedures Specific hazards: If the electrolyte comes into contact with water, it can generate detrimental hydrogen fluoride. Since the leaked electrolyte is an inflammable liquid it should not be brought close to fire.
