3. Hazards A sealed Nickel-Metal Hydride cell is not hazardous on principle. 3.1 Physical No risk if cells are used for its intended purpose and according to valid directions for use. 3.2 Chemical In normal use, no chemical risk. On some bad using conditions (high over charge, external short circuit…) and in case of a bad functioning, some electrolyte can be removed from the cell by the security vent. In these cases the risk is the caustic nature of electrolyte.

advice. S 36: Wear suitable protection clothing. S 37: Wear suitable gloves. S37/39: Wear suitable gloves and eyes/face protection. S45: In case of accident or if you feel unwell, seek medical advice immediately. 4. FIRST AID MEASURES In case of electrolyte leakage precautions must be taken to avoid personal to get in direct contact with it. If it accidentally happens following must be done: 4.1 Inhalation Fresh air. Rinse mouth and nose with water. Medical treatment. 4.
