4/5
Exposure control (in case of electrolyte leakage from the battery)
Acceptable concentration : Not specified in Japanese industrial hygienic association
and ACGIH
Facilities :Ventilation should be noted such as equipped with the
limited spot area exhaust device used for the battery storage
place.
Protective clothing : The protection glasses, the mask for disaster prevention,
and the protection gloves are used.
Physical and Chemical Properties
Externals : The nickel hydrogen storage battery is stored in the plastic resin case or
tube. The voltage value depends on the number of built-in batteries used in
battery pack.
Stability and Reactivity
The external short, the crushing transformation, and the high temperature exposure of
100℃ or more cause abnormal heat generation and the fire.
Toxicological information
When the electrolyte leaks from the product
Acute toxicity : LD50 2g/Kg oral rat
(Based on material safety data sheet of liquid potassium hydro oxide)
Stimulation : The cornea inflammation is caused when the electrolyte gets in eye.
The long time exposure to the electrolyte stimulates mucous membranes
of the bronchial tube and eye.
