w8Electrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.
9EXTERNAL: Flush with
plenty of water.9INTERNAL: Drink large
quantities of water or milk
and immediately call a
physician.
9EYES: Flush with water for
15 minutes and seek prompt
medical attention.
8Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes,
etc., away from the battery and
provide sufficient ventilation
when charging it in an
enclosed space.
8KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OF
CHILDREN.
