3. HAZARDS
A sealed Nickel-Cadmium 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鈥?) 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.
The toxic properties of the electrode materials are hazardous only if the materials are released by damaging
the cell or if exposed to fire.

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 m=nose with water. Medical treatment.
4.2 Skin contact
Rinse immediately with plenty of water. Medical treatment.
4.3 Eyes Contact
Rinse immediately with plenty of water during at least 15-30 min. Immediate hospital treatment.
Eye Specialist.
4.4 Ingestion
If the injured is fully conscious: plenty of drink, preferably milk. Do not induce vomiting.
Immediate Hospital treatment.
5. FIRE FIGHTING MEASURES
5.1 Extinguishing media
Suitable: Class D-Dry chemical, sand.
Not to be used: Water.
5.2 Special exposure hazards
Cells can be overheated by an external source or by internal shorting and develop potassium
hydroxide mist and / or hydrogen gas. In fire situations fumes containing. Nickel, cobalt and iron may
evolved.
5.3 Special protective equipment
Use self contained breathing apparatus and full fire-fighting protective clothing.
