cause battery gas to explode. People
have been hurt doing this, and
some have been blinded. Use a
flashlight if you need more light.

burn you. Do not 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
