There are a number of safety cautions in this book. A box with the word CAUTION is used to tell about things that could hurt you or others if you were to ignore the warning.

Caution: These mean there is something that could hurt you or other people.

Cautions tell what the hazard is and what to do to avoid or reduce the hazard. Read these cautions.

A circle with a slash through it is a safety symbol which means "Do Not," "Do Not do this" or "Do Not let this happen."
