"The Agricultural Worker Protection Standard (WPS) is a regulation issued by the U.S. Environmental Protection Agency in 1992 and amended in 1995. It covers pesticides that are used in the production of agricultural plants on farms, forests, nurseries, and greenhouses. The WPS requires you to take steps to reduce the risk of pesticide related illness and injury if you (I) use such pesticides, or (2) employ workers or pesticide handlers who are exposed to such pesticides. This fact sheet will help you understand how to comply with WPS requirements for displaying information about pesticide applications. These questions were submitted to the Agency by people seeking clarification on this part of the regulation, and have been answered by EPA's Office of Compliance."
