Agricultural Worker Protection Standard (WPS)
EPA's Agricultural Worker Protection Standard (WPS) aims to reduce pesticide poisonings and injuries among agricultural workers and pesticide handlers. The WPS offers occupational protections to over 2 million agricultural workers and pesticide handlers who work at over 600,000 agricultural establishments. In 2015, EPA revised the WPS to decrease pesticide exposure incidents among farmworkers and their family members. Fewer incidents means a healthier workforce and fewer lost wages, medical bills and absences from work and school.
Pesticide safety training materials with the expanded content required by the 2015 WPS must be used to train workers and handlers. EPA-approved training materials for national use are available on the WPS Materials webpage.

WPS and the COVID-19 Public Health Emergency
On June 1, 2020, EPA issued guidance for agricultural employers and pesticide handlers seeking respiratory protection when using pesticides in agricultural production. The guidance addresses respirator shortages and reduced availability of respirator fit testing related to pesticide uses covered by the WPS during the COVID-19 public health emergency. An amendment issued May 7, 2021, revises the expiration date of the “annual fit test delay” option, which is applicable to all NIOSH-approved respirators that require fit testing. The “annual fit test delay” option is now valid until Sept 30, 2021. The remainder of the June 2020 memorandum remains valid and unrevised.
It is important to note that neither the options in the June 2020 memorandum nor the amendment provide a waiver of regulations or label requirements. Handlers and their employers are expected to make every effort to comply with all applicable pesticide product label and WPS requirements, and to exhaust all available compliance options before considering the options presented in June 2020 memorandum.
Also in June 2020, EPA released guidance regarding the annual pesticide safety training requirements outlined in the Agricultural Worker Protection Standard (WPS) that offers flexibility during the COVID-19 public health emergency. Read it here.
Application Exclusion Zone
In 2015, EPA finalized various significant revisions to the 1992 WPS. Among the 2015 revisions was a new provision requiring agricultural employers to keep workers and all other individuals out of an area called the “application exclusion zone” (AEZ) during outdoor pesticide applications. The AEZ is the area surrounding pesticide application equipment that exists only during outdoor production pesticide applications.
On October 30, 2020, EPA finalized updates to the Application Exclusion Zone (AEZ) provisions under the WPS regulation. At this time, there is no implementation of the 2020 AEZ rule (a preliminary injunction has stayed the effective date of the 2020 AEZ rule and enjoined EPA from implementing the 2020 revisions). To view the final rule, please visit docket EPA-HQ-OPP-2017-0543.

Groups Covered by the WPS
The WPS protects two types of employees on farms, forests, nurseries and greenhouses from occupational exposure to agricultural pesticides:
- 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 include anyone employed for any type of compensation (including self-employed) doing tasks such as:
*Some requirements apply to anyone doing certain tasks, such as handling pesticide application equipment or cleaning or laundering pesticide-contaminated personal protective equipment.
Complying with the WPS
This section provides an overview of who is required to comply with the WPS and a list of compliance requirements.
In general, employers are responsible for WPS compliance. These include:
- Owners/employers on agricultural establishments that grow and harvest for commercial production:
- Fruits and vegetables on farms.
- Timber and trees in forests and nurseries.
- Plants in greenhouses and nurseries.
- Employers of researchers who help grow and harvest plants.
- Employers at commercial pesticide handling establishments
Under the WPS, all employers are required to do the following:
- Do not retaliate against a worker or handler.
- Provide annual pesticide safety training.
- Provide access to specific information for workers and handlers at a central location during normal work hours, including (agricultural employers only):
- Pesticide applications on the establishment;
- Safety Data Sheets for pesticides applied on the establishment; and
- Pesticide safety information that includes emergency information.
- Provide WPS-required safety, pesticide application, and hazard information to workers and handlers or their designated representative, or to treating medical personnel, if requested. For additional details, see the Designated Representative section of this webpage or Chapter 2 of the WPS How to Comply Manual. See full requirements at 40 CFR 170.311(b).
- Provide decontamination supplies.
- Exchange information (between a commercial handler employer and an operator of an agricultural establishment).
- Provide emergency assistance by making transportation available to a medical care facility in case of a pesticide injury or poisoning and providing information about the pesticide(s) to which the person may have been exposed.
In addition to the duties listed above for all employers, employers of workers are required to do the following:
- Implement restrictions during applications by keeping workers and other people out of the treated field and application exclusion zones.
- Implement restricted-entry intervals (REIs).
- Implement protections for early entry by workers, including:
- Providing access to labeling information;
- Specific information on early entry tasks; and
- Required early entry Personal Protective Equipment.
- Notify workers about applications and pesticide-treated areas and not to enter during the REI by:
- providing oral warnings; or
- posting warning signs.
In addition to the duties listed above for all employers, employers of pesticide handlers are required to do the following:
- Implement restrictions during applications by ensuring that pesticides applied do not contact workers or other people. Also, handlers must suspend an application if workers or other people are in the application exclusion zone.
- Monitor handlers working with toxic pesticides.
- Provide specific instructions for handlers.
- Provide access to labeling information for handlers.
- Take steps to ensure equipment safety.
- Personal Protective Equipment (PPE):
- Provide required PPE in clean and good operating condition.
- Ensure PPE is worn correctly.
- Provide a clean place for storing personal clothing and removing PPE.
- Care for, maintain and replace damaged or worn PPE.
- Replace respirator purifying elements.
- Dispose of contaminated PPE.
- Provide instructions for people who clean PPE.
- Provide a medical evaluation, fit test and respirator training to handlers required to wear a respirator by the pesticide label.
Exceptions to the WPS
The following situations are exceptions from the requirements in the WPS
- Owners and immediate family members on family-owned farms are exempt from many of the WPS requirements.
- Certified or licensed crop advisors who perform crop advisor tasks are exempt from certain WPS provisions including pesticide safety training.
- Limited and narrow circumstances: The WPS does not apply when pesticides are applied on an agricultural establishment in certain limited circumstances.
The designated representative provision was added to the 2015 revision of the WPS. The following information provides additional explanation of this provision and examples to help groups covered by the WPS understand how to use of the designated representative provision correctly.
Per 40 CFR § 170.305 of the 2015 WPS regulation revision, a “designated representative” is any person(s) designated in writing by a worker or handler to exercise a right of access on his or her behalf to request and obtain a copy of the pesticide application and hazard information from a worker’s employer. The employer is required to make this information available to the employee or his/her designated representative under §170.311(b)(1) of this part.
Examples of why a worker or handler may choose to utilize a designated representative include:
- If there is a language barrier;
- If the worker or handler has moved and cannot access the information themselves;
- If a case worker needs information for workers compensation review.
Under the regulations, a designated representative may request WPS-required pesticide application and hazard information for applications made while the worker or handler was employed on the establishment (going as far back as two years). This request, made to the worker’s employer, must be in writing.
Under the regulations, the written request must contain the following:
- The name of the worker or handler being represented;
- A description of the specific information being requested, including:
- Dates of employment of the worker or handler,
- The date(s) for which the records are requested,
- Type of work conducted by the worker or handler during the period for which the records are requested, and
- The specific application and hazard information requested;
- A written statement clearly designating the representative to obtain this information on the worker’s or handler’s behalf, with the worker’s or handler’s printed name and signature, the date of the designation, and the printed name and contact information for the designated representative; and
- Where the worker’s employer should send the information, if the information is to be sent.
As specified in 40 CFR 170.311(b)(1), designated representatives may access:
- A copy of the safety data sheet.
- The name, EPA registration number, and active ingredient(s) of the pesticide product.
- The crop or site treated and the location and description of the treated area.
- The date(s) and times the application started and ended.
- The duration of the applicable labeling-specified restricted-entry interval for that application.
Under the regulations, the employer must provide a copy or access to the requested information within 15 days of receiving the request. If the worker’s employer has previously provided the record without cost to the same worker or handler or their designated representative, a reasonable fee may be charged for duplicate records, but the fee may not include any discriminatory costs or overhead charges.
All states enforce the federal WPS. Additionally, some states have implemented their own worker protection laws. Examples of designated representative requirements from states include:
- Florida Agricultural Worker Safety Act (FAWSA) includes a “designated representative” definition; summarized by University of Florida Institute of Food and Agricultural Sciences Extension Exit
- California Department of Pesticide Regulation 3 CCR 6761. Hazard Communication for FieldworkersExit; summarized at Right to Obtain Information Exit
- Texas Agricultural Hazard Communication Law contains a provision for a “designated representative;” summarized at Texas Worker Protection Law Exit
