Agricultural Worker Protection Standard (WPS) for Pesticides

The WPS applies to all pesticides whether restricted or general use. You will know the pesticide product is covered by the WPS if you see the following statement in the “Directions for Use” section of the pesticide labeling:

Agricultural Use Requirements

Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR Part 170. This standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about personal protective equipment, notification of workers, and restricted-entry intervals.

The primary WPS resource is the How to Comply manual, developed by EPA. The manual is available from your State Lead Agency (SLA) for pesticide regulation, pesticide education office of the Cooperative Extension Service, the EPA Region 1 office and EPA’s National Agricultural Compliance Assistance Center. Every agricultural producer should have a copy of the EPA How to Comply manual.

The WPS is a US EPA regulation, 40 CFR Part 170. It covers pesticides that are used in the production of agricultural plants on farms, forests, nurseries, and greenhouses. The WPS requires the owner or employer to take steps to reduce the risk of pesticide-related illness and injury: 1) if pesticides are used on the farm or 2) workers or pesticide handlers are employed who may be exposed to such pesticides.

Here’s a brief summary of the major elements of the WPS. Each one of these categories is described in greater detail in the EPA How to Comply manual. Producers should refer to the How to Comply manual for complete explanations of the requirements of the Worker Protection Standard.


To ensure employees will be informed about exposure to pesticides, the WPS requires:

  • Annual Pesticide Safety Training — for workers and handlers, (new)
  • Pesticide safety poster — to be displayed for workers and handlers,
  • Access to labeling information — for pesticide handlers and early-entry workers, and
  • Access to specific information — a centrally located Application List of pesticide treatments on the establishment and safety data sheets for each of the pesticides used. (new)


To ensure employees will be protected from exposures to pesticides, the WPS requires employers to:

  • Prohibit handlers from applying a pesticide in a way that will expose workers or other persons,
  • Exclude workers and others from areas being treated with pesticides and areas that are Application Exclusion Zones, (new)
  • Exclude workers from areas that remain under a restricted entry interval (REI) with narrow exceptions,
  • Protect early-entry workers who are doing permitted tasks in treated areas during an REI — requirements include special instructions and duties related to correct use of Personal Protective Equipment (PPE),
  • Notify workers about treated areas so they can avoid inadvertent exposures,
  • Protect handlers during handling tasks — requirements include monitoring while handling highly toxic pesticides and duties related to correct use of PPE, and
  • Provide medical evaluations, respirator fit test and training for all pesticide applicators, pesticide handlers and early entry workers who are required to wear respirators per the pesticide label instructions. (new)


To mitigate exposures that employees receive, the WPS requires:

  • Decontamination sites — providing handlers and workers an ample supply of water, soap and towels for routine washing and emergency decontamination, and
  • Emergency assistance — making transportation available to a medical care facility if an agricultural worker or handler may have been poisoned or injured by a pesticide and providing information about the pesticide(s) to which the person may have been exposed.

Agricultural Owner Exemptions

Even if you are the owner of the farm, forest, nursery, or greenhouse and you or members of your family do all the work there, you are a “WPS employer.” You must comply with SOME of the WPS requirements, such as adhering to restricted entry intervals, personal protective equipment (PPE) and ALL the specific requirements listed in the pesticide labeling.
If you hire commercial handlers, certain information must be given from you (the operator) to the commercial handler employer.

  • Specific location and description of any areas that may be treated with a pesticide or be under an REI while handler is there, or that the commercial handlers may be in (or walk within 1/4 mile of), and
  • Restrictions on entering those areas.

Crop Advisors

The WPS requires employers to provide certain protections to their employees who are working as crop advisors. Examples of crop advisors are crop consultants, scouts, and integrated pest management monitors. An independent or commercial crop advisor is any person working as a crop advisor who is employed (including self employed) by anyone other than the agricultural establishment on which the work is being done. Certain provisions of the WPS apply to crop advisors depending on when the advisor is on the farm and when the pesticide has been applied.

Commercial Handlers

Employers of commercial handlers must make sure that their customer — the operator of the farm, forest, nursery or greenhouse, knows certain information such as: specific location and description of the area treated with the pesticide, time and date pesticide is to be applied, product name, EPA registration number, active ingredient(s), REI for the pesticide, whether the labeling requires treated area posting and oral notification and any other specific requirements on the pesticide labeling concerning protection of workers and other persons during or after application.
