-warehousing
-construction
-boiler, furnace, or engine rooms
-occupations involving work from a ladder, scaffold, windowsill, or similar structures, or places more than five feet in height

Another Arizona Law (ARS §23-231) has more restrictions for employment of children under 18 years old.

In addition, there are limitations placed on the hours that may be worked by children under the age of 16. Minors under the age of 16 may not work more than 3 hours per day and 18 hours per week when enrolled in school. When not enrolled in school or when school is not in session, minors under the age of 16 may not work more than 8 hours per day and 40 hours per week.
