Worker Protection Standard for Agricultural Pesticides: Key Features

David E. Baker
Food Science and Engineering Unit

On Aug. 21, 1992, the U.S. Environmental Protection Agency (EPA) issued the final Worker Protection Standard (WPS) governing the protection of employees on farms and in forests, nurseries and greenhouses from occupational exposure to agricultural pesticides. The Standard covers workers in areas treated with pesticides and employees who handle pesticides for use in the production of agricultural plants. The new Standard took effect on Oct. 21, 1992, and is enforceable when a WPS-labeled pesticide is being used.

The new Standard expands the requirements for issuing warnings about pesticide applications, using personal protective equipment and restricting entry to treated areas. New requirements have also been added for decontamination, emergency assistance, maintaining contact with handlers of highly toxic pesticides and pesticide safety training.

The new Standard also requires that pesticide registrants add appropriate labeling statements referencing the WPS regulations and specifying application restrictions and other regulatory requirements.

Affected employers

Agricultural employers who will probably need to comply with the WPS are:

Most WPS provisions are protections that you as an employer must provide to your own employees and, in some instances, to yourself. Owners of agricultural establishments and their immediate families are exempt from many of the WPS requirements

Affected employees

The WPS requires employers to take steps to protect two types of agricultural employees: workers and pesticide handlers.

The terms "workers" and "pesticide handlers" are defined very specifically in the WPS, but in general terms they can be defined as:

Depending on the task(s) being performed, employers may need to provide the same employee with worker protection in some instances and pesticide handler protections in others.

General WPS provisions

The provisions of the new Worker Protection Standard are intended to:

Eliminate pesticide exposure
The final rule of the WPS reduces pesticide exposure through several requirements:

Mitigate pesticide exposure
Exposure to pesticides is mitigated in the final rule through the following provisions:

Inform employees about pesticide hazards
The final rule provides information about pesticide hazards through the following requirements:

Implementation schedule

Pesticide labels will soon reflect the new WPS requirements. All pesticide products affected by the WPS will carry a statement under the new Agricultural Use Directions section of the label. This statement will instruct users that they must comply with all provisions of the WPS. If you are using a pesticide product with labeling that refers to the Worker Protection Standard, you must comply with the WPS.

The Worker Protection Standard has established a compliance schedule that will implement the provisions of the WPS in two phases. When a pesticide with WPS labeling is used, this schedule is as follows:

Workers and handlers do not have to comply with the WPS until their pesticide labels are revised to include the specific provisions of the Standard. According to the Standard, pesticide labels do not have to be revised and in the channels of trade until April 21, 1994. Products that do not bear the required WPS statements may not be sold or distributed by anyone after Oct. 23, 1993.
