What type of areas does the WPS apply to?

The Worker Protection Standard (WPS) is specifically designed to protect agricultural workers by reducing their risk of pesticide exposure. This standard applies to a variety of environments where pesticide use is prevalent, which includes farms, forests, and nurseries, as well as enclosed spaces such as greenhouses.

The key reasoning for this choice being correct stems from the WPS's intention to address the protection of workers in settings heavily influenced by commercial agricultural practices. The inclusion of forests and nurseries as applicable sites reflects the wide-reaching scope of pesticide use in diverse ecological and agricultural systems.

While other options may pertain to certain environments, they do not encompass the comprehensive nature of where the WPS is applicable. For instance, limiting the applicability to only agricultural fields or focusing solely on commercial garden centers would exclude critical areas such as nurseries and greenhouse operations, where worker protection is also paramount.
