A covered employer shall provide for use and at no cost to each agricultural laborer employed by the covered employer any protective clothing, equipment, or device that is specified on the label for the activities in which the agricultural laborer is engaged as part of the agricultural laborer's duties. If the label does not specify protective clothing, then the covered employer shall provide the protective clothing, equipment, or device specified in the most current appropriate material safety data sheet (generally referred to as the safety data sheet), crop sheet, or as provided in Chapter 7, Subchapter D of this title (relating to Use and Application), whichever is more protective. This section does not require that the covered employer provide the long sleeve shirts, pants, shoes, and socks customarily provided by the agricultural laborers.
