3. HAZARDS
A- Human hazards
A sealed Nickel-Cadmium cell is not hazardous in normal use.
3.1 Physical
Nickel plated steel can do not present any risk if cells are used for its intended purpose
and according to valid directions for use.
3.2 Chemical
Nickel plated steel can do not present chemical risk in normal use.
In case of misuse (abusive over charge, reverse charge, external short circuit…) and in
case of default, some electrolyte can leak from the cell through the safety vent.
In these cases refer to the risk of the Alcaline hydroxides.
The toxic properties of the electrode materials are hazardous only if the materials are
released by mechanical damaging the cell or if exposed to fire.
