An Introduction to the Federal
Worker Protection Standard for Agricultural Employees
On August 13, 1992, the US EPA promulgated the Worker Protection Standard (WPS). The regulation protects agricultural employees who work in or on farms, forests, nurseries and greenhouses from risk due to occupational exposure to pesticides or pesticide residue.
Purpose of the WPS
The WPS sets out required work place practices that are intended to do three things:
- Eliminate or reduce employee exposure to pesticides
- Mitigate exposures that occur
- Inform employees about the hazards of pesticides
Applicability of the WPS
The WPS applies to the working conditions of two types of employees (including student labor and work-study student employees):
- pesticide handlers - those who handle
agricultural pesticides (mix, load, apply, clean or repair equipment, act
as flaggers or crop advisors, or perform other tasks involving direct contact
- agricultural workers - those who perform tasks related to the cultivation and harvesting of plants on farms or in greenhouses, nurseries or forests.
The WPS applies to farms, forests, nurseries or greenhouses where pesticides are used in the production of agricultural plants (plants grown or maintained for commercial or research purposes including food, feed and fiber plants, trees, turf grass, flowers, shrubs, ornamentals and seedlings).
The WPS does not apply to the following uses:
government-sponsored public pest control including mosquito control
on livestock and other animals
on plants grown for other than commercial or research purposes (e.g., home gardens and greenhouses)
on ornamental plants in parks, lawns & grounds (including commercial lawn care)
uses not directly related to agricultural plant production such as structural, right-of-way, pasture and rangeland applications
control of vertebrate pests
as attractants or repellents in traps
on harvested portions of plants or timber
research uses of unregistered pesticides
To schedule Worker Protection Standard training, contact the
Department of Environmental Health & Safety
NOTE: By law, employees covered under the WPS must receive training prior to or within 5 days of employment. The training certifies an individual for five years. Certificates of training are kept at UConn's Department of Environmental Health & Safety; copies are sent to the employee's department.
