SECTION 2: Hazards identification

A Li-ion battery cell is a sealed article, with a typical voltage of 3.6V DC per cell. A Li-ion battery is an article with no intended release of its substances. Under normal conditions of use, the battery does not release its content as it is sealed. In case of accidental release of the battery content, the operator may be exposed to one or more of the battery constituents. Please refer to the paragraph No. 6 “Accidental Release Measures”. EXPOSURE TO HIGH VOLTAGE In case of large electrical serial assembly, modules and full battery may offer high Voltage hazard (> 36 Volts). The presence of the High Voltage warning sign requires dedicated intervention equipment. Lithium-ion batteries used in Hybrid and full Electric Vehicles (also in other applications) may have Voltage larger than 60V. Therefore the approach of a battery used in an EV should consider the hazard of Electrical Shock which characterize these batteries. The following prevention measures should be taken when approaching a high voltage battery or rescue a victim. Use insulating gloves or protections. Turn off the source of electricity, if possible. If not, move the source away from you and the person (victim), using a dry, no conducting object made of cardboard, plastic or wood. Check for signs of life (breathing, coughing or movement). If absent, begin cardiopulmonary recovery (CPR) immediately. Prevent shock. Lay the person down and, if possible, position the head slightly lower than the body with the legs elevated. After coming into contact with electricity, the person should see a doctor to check for internal injuries, even if he or she has no obvious signs or symptoms. SPECIAL HAZARDS FOR HUMAN HEALTH AND ENVIRONMENT There is no hazard when the measures for handling and storage are followed. In case of cell damage, possible release of dangerous substances and a flammable gas mixture.
