A- Human hazards
A rechargeable Nickel-IRON 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 with electrolyte through the safety vent.
In these cases refer to the risk of the 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.
Please note that the rechargeable Ni-FE batteries have no electrolyte inside, so there is no electrochemistry reaction.
