PRODUCT SAFETY DATA SHEET
(1) Use powder-type ABC extinguisher.
(2) When corrosive gas could be generated in the event of fire fighting,
use appropriate breathing apparatus.
(3) Extinguishing a fire with a large amount of water may be an
effective method.
However, this should be considered as a supplementary means.
If there are no readily available large amounts of water, use dry sand
instead; as the application of only a small amount of water may
temporarily act as an accelerant and affect the fire adversely while the
hydrogen storage alloy is burning.
(4) Remove the flammable materials from the fire.
(5) If fire occurs nearby to batteries, move them to a safe place.
(1) Fire may occur when:
Short circuit-induced arcing occurs.
A large current is applied to a module or a cell.
(2) Explosion may occur when:
The battery is contained in a hermetic container, since oxygen and/or
hydrogen may be generated by the battery. The battery itself will not
explode in normal conditions.
(3) Fire and explosion may occur when:
The battery is over-charged or over-discharged. The battery is over
100 deg C.
The battery is in a hermetic container with an ignition source nearby
and overcharge or overdischarge occurs.
When the alkaline electrolyte leaks from battery.
(1) Wipe off with a towel.
(2) Keep away from flames.
(3) Protective glasses and rubber gloves should be worn.
Short circuit should be prevented since heat generation and/or fire
may result.
The battery should not be disassembled and/or reconstructed for the
following reasons:
• If a cell is disassembled, alkaline electrolyte may leak.
• If a module is disassembled, short circuiting may occur.
• If a module is disassembled, cells will be damaged and alkaline
electrolyte may leak.
Battery should not be over-charged or over-discharged to prevent possible
oxygen and/or hydrogen generation.
Battery should not be used in a hermetic container since the container may
explode due to gas generated from the battery.
When alkaline electrolyte leakage from the battery occurs, necessary
action should be taken as follows:
Not specified in Japanese Industrial Hygienic association and ACGIH.
(1) Ventilation should be considered. Limited exhaust device or other
ventilation device should be used.
(2) Exhaust system or exhaust hole is required when the battery is used
in a container.
Safety glasses, mask, and gloves should be worn.
