LITHIUM ION BATTERY PACK

SECTION 2: Hazards identification

Product definition

This product is a lithium ion battery.

Health hazards

This product is considered a manufactured article and presents negligible health, or reactivity hazards under typical use conditions. If exposure to the electrolyte solution occurs from puncture, heating or other destruction of the outer case, contact with the solution may be harmful by inhalation, skin or eye contact. Inhalation of fumes from burning electrolyte solution may cause burns to respiratory system. Skin or eye contact with the electrolyte solution may also produce burns, especially if contact is prolonged. Contact with the electrodes may result in electric shock under certain circumstances of contact. Flammability Hazards: Batteries can explode during a fire. If involved in a fire, this product can burn and produce toxic gases (e.g. carbon monoxide, carbon dioxide, hydrogen fluoride, phosphine, phosphorous oxides, lithium oxides, lithium hydroxide, nickel oxides, copper oxides and other metal oxides). During a fire involving this product care should be taken to avoid inhalation of fumes. During charging of this battery, a lithium graphite intercalation phase is formed (where lithium and graphite molecules are combined), which is highly flammable and corrosive, but is not released under normal circumstances. Reactivity Hazards: The electrolyte solution can react with water to form hydrofluoric acid. Contact with the anodes can produce hydrogen gas. Environmental Hazards: This product is not expected to cause harm if released to the environment. Emergency Response Considerations: Emergency responders must wear proper personal protective equipment (and have appropriate fire protection) suitable for the situation to which they are responding.
