5. FIRE FIGHTING MEASURES 5.1 Extinguishing media Suitable: Class D-Dry chemical, sand, CO2. Not to be used : Water. 5.2 Special exposure hazards Cells can be overheated by an external source or by internal shorting and release alcaline electrolyte mist or liquid. In fire situations fumes containing Cadmium may evolve. Electrolyte reacts with zinc, aluminum, tin and other active materials releasing flammable hydrogen gas. In case of PVC sleeved products, the combustion releases chloride gas. 5.
