Pesticide Worker Safety

Coverage and Duties under the Worker Protection Standard

On this page:

Who is protected by the worker protection standard?

The WPS protects employees on farms, forests, nurseries and greenhouses from occupational exposure to agricultural pesticides and covers two types of employees:

  • Pesticide handlers: those who:
    • mix, load or apply agricultural pesticides;
    • clean or repair pesticide application equipment; or
    • assist with the application of pesticides.
  • Agricultural workers: those who perform tasks related to growing and harvesting plants on farms or in greenhouses, nurseries or forests.
  • Workers include anyone employed for any type of compensation (including self-employed) doing tasks such as:
    • carrying nursery stock;
    • repotting plants;
    • watering; or
    • other tasks directly related to the production of agricultural plants on an agricultural establishment.
  • Workers do NOT include employees such as:
    • office employees;
    • truck drivers;
    • mechanic; and
    • any other workers not engaged in worker/handler activities.

Some requirements apply to anyone doing certain tasks, such as handling pesticide application equipment or cleaning or laundering pesticide-contaminated personal protective equipment.
