Worker Protection Standard (WPS)

The Worker Protection Standard (WPS) is an EPA regulation that is administered by Oregon OSHA and aims to reduce the risk of pesticide poisoning to agricultural workers and pesticide handlers. The College of Agricultural Sciences and the Oregon Agricultural Experiment Station continuously strives to maintain the health and safety of our employees and therefore we adhere to WPS rules for all subject employees. Subject employees are those who are:

  • 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.

  The WPS requires that owners and employers on agricultural establishments:

  • Provide protections to workers and handlers from potential pesticide exposure.
  • Train them about pesticide safety.
  • Provide mitigation when exposures occur.

Recent revisions by the EPA have brought changes to the existing requirements. These changes will be implemented, starting in January of 2017. As new information and resources are developed, they will be provided below.
