FIRE FIGHTING MEASURES GENERAL HAZARD Cell is not flammable but internal organic material will burn if the cell is incinerated. Combustion products include, but are not limited to hydrogen fluoride, carbon monoxide and carbon dioxide. EXTINGUiSHING MEDIA Use extinguishing media suitable for the materials that are burning. SPECIAL FIREFIGHTING INSTRUCTIONS If possible, remove cell(s) from fire fighting area. If heated above 130°C, cell(s) may Swell/explode/vent. FIREFIGHTING EQUIPMENT Use NIOSH/MSHA approved full-face self-contained breathing apparatus (SCBA) with full protective gear. 5. ACCIDENTAL RELEASE MEASURES ON LAND Place material into suitable containers and call local fire/police department. IN WATER If possible, remove from water and call local fire/police department.
