This FAQ addresses the WPS requirements for agricultural employers when they hire a commercial pesticide handler employer (CPHE) (e.g., custom applicators) to make pesticide applications on their agricultural establishment. There are additional responsibilities for WPS compliance for agricultural employers who employ their own workers and handlers.
Whenever a commercial pesticide handler will apply a pesticide on your agricultural establishment, the CPHE must provide you with certain information. The purpose of this exchange is to give you the information you need to comply with WPS. After all, you need to inform workers about treated areas with restricted entry, and you need to display the appropriate pesticide application information (record) and accompanying Safety Data Sheets (SDSs).
In addition, you must provide certain information to the CPHE about treated areas on the agricultural establishment. The purpose of this exchange of information (and the requirement for the CHPE to pass it along to the handler) is to ensure that the commercial pesticide handler doing the work on the agricultural establishment is aware of treated areas with restricted entry within ¼ mile of where he or she will be working.
Before a commercial pesticide handler (the employee of the CPHE) enters an agricultural establishment, you must inform the CPHE about treated areas and any restricted-entry intervals on the establishment, and the CPHE must provide that information to the commercial pesticide handler. The CPHE must obtain this information so it can be communicated to their handler employees.
You must provide to the CPHE:
To allow you to inform workers on the establishment about a pesticide application that is, or will be performed, the CPHE (for-hire/custom applicator) must inform you of the following:
The CPHE must provide you with updated information PRIOR to the application when there are any changes to:
Changes to the estimated application end time of less than one hour do not need to be reported to you.
If the product information changes or there are other changes to the date, start time, or end time, the CPHE must provide the updated information to you within 2 hours after completing the application.
Based on the information provided by the CPHE, you must post the treated area with designated WPS warning signs and/or provide oral warnings to your workers. The purpose of this notification is to inform workers of treated areas under an REI, so they know to keep out of those treated areas.
Additionally, you must display the pesticide application information (record) and SDS(s) for the pesticide application conducted by the CPHE.
It is your responsibility to keep workers and others out of the treated area and the application exclusion zone (AEZ) during pesticide applications.
You may not allow a pesticide to be applied, or a suspended application to be resumed, while anyone on the establishment is in the treated area or within the AEZ.
Effective January 2, 2018, there is a separate AEZ requirement that applies to the pesticide handler making a pesticide application (the commercial handler in this situation) that requires the handler to temporarily suspend the application if any worker or other person (other than an appropriately trained and equipped handler involved with the application) is in the:
The AEZ may extend beyond the boundaries of your establishment.
It is the CPHE and the commercial handler's responsibility to ensure that no pesticide is applied in a manner that contacts, directly or through drift, any worker or other person, other than an appropriately trained and equipped handler(s) involved in the application. This responsibility is a label requirement, shared by everyone involved in the application.
