WARNING
Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and
lighters. Never expose a battery
to an open flame or electric
sparks. Batteries give off a gas
which is highly flammable and
explosive.For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery.Do not let battery fluid contact
eyes, skin, fabrics, or paint
because battery fluid is a corro-
sive acid. If battery fluid gets on
your skin or in your eyes, immedi-
ately flush the area with water
thoroughly. Seek medical help
immediately if acid has entered
the eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and seek medical attention
immediately.
