Given the nature of chemical substances used in batteries and the processes that occur on charge, discharge and an open circuit various hazards may be created. These hazards are of a chemical or mechanical nature. Electrical hazards are of little importance. An exception is the generation of sparks from batteries which may ignite nearby flammable gases or liquids. The mechanical hazards are generally caused by chemical or electromechanical reaction that triggers ruptures or explosions.
