Worker Protection Standard

Worker Protection Standards

The Worker Protection Standard (WPS) is a federal regulation issued by U.S. EPA. The WPS applies to growers who own or manage a farm, forest, nursery, or greenhouse where pesticides are used in production of agriculture plants and have one or more of these situations:

  1. Hire or contract for services of agricultural workers who receive compensation and do tasks such as harvesting, weeding or watering.
  2. Operate a business or farm where pesticides are applied by handlers who receive compensation and do tasks related to mixing, loading, transferring or applying pesticides. Click HERE for complete list of handlers tasks.
  3. Operate a business where crop advisor tasks are performed. Click HERE for a complete list of crop advisor tasks.
