Using
a match
near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use
a flashlight if
you need more light.
~ Be sure the battery has enough water. You don’t
need to add water
to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take care
of that first. If you don’t, explosive gas could be
present.
Battery fluid contains acid that can burn
you.
Don’t get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately. Fans
or other moving engine
parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.
