In this chapter:
(1) “Agricultural laborer” means a person who plants, cultivates, harvests, or handles an agricultural or horticultural commodity in its unmanufactured state as determined by rule of the department, and includes an agricultural laborer who handles a chemical covered by this chapter. Office workers, cooks, maintenance workers, security personnel, and nonresident management are not agricultural laborers, except for purposes of a gross annual payroll determination, unless their job performance routinely involves potential exposure to chemicals covered under this chapter.
