Worker Protection Standard, 40 CFR Parts 156 and 170
The Environmental Protection Agency’s (EPA) Worker Protection Standard (WPS) is a federal regulation intended to prevent unreasonable adverse health effects from occupational exposures to pesticides among agricultural workers, pesticide handlers and bystanders who may be on or near agricultural establishments. The WPS was originally issued in 1992. In November 2015, the EPA published a revision to the WPS. The revision became effective on January 1, 2016, with a January 2, 2017, compliance date for most of the new requirements.
There are certain provisions within the 2015 revision that employers will not need to comply with until January 1, 2018. This later date applies new requirements for pesticide safety training for workers and handlers, pesticide safety information and for handlers to suspend applications when workers or other persons are in the application exclusion zone.
The WPS covers farm, forestry, greenhouse and nursery workers from occupational exposure to agricultural pesticides, including anyone involved in picking, cutting, weeding and inspecting.
- Agricultural workers - those who perform tasks related to the cultivation and harvesting of 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 or watering, related to the production of agricultural plants on an agricultural establishment. Workers do not include office employees, truck drivers, mechanics and any other workers not engaged in worker or handler activities.
- Pesticide handlers - those who mix, load or apply agricultural pesticides; clean or repair pesticide application equipment; or assist with the application of pesticides in any way.
The WPS establishes responsibilities for the employers of both agricultural and pesticide handling workers to prevent exposure to hazardous chemicals contained within pesticides. The standard also places a responsibility on the employers of pesticide handlers to take precautions to ensure the unsuspecting public is not exposed to the potentially hazardous chemicals as well.
The requirements for the employers of agricultural workers cover the following areas:
- Establishment specific information
- Entry restrictions during pesticide applications
- Entry restrictions after pesticide applications
- Oral and posted notifications or entry restrictions
- Decontamination supplies
For the employers of pesticide handlers the requirements cover the following areas:
- Knowledge of labeling, application-specific and establishment-specific information for handlers
- Requirements during applications to protect handlers, workers and other persons
- Personal protective equipment (PPE)
- Decontamination and eye flushing supplies for handlers
The 2015 revision to the WPS enhances the protections already afforded to agricultural workers and pesticide handlers under the original standard. The areas of the standard that were strengthened pertain to training, notification, pesticide safety and hazard communication information, use of personal protective equipment (PPE) and the providing of supplies for routine washing and emergency decontamination.
Among the specifics, the revision establishes a minimum age limit of 18-years old for employees working as pesticide handlers and early entry agricultural workers. Early entry workers perform tasks involving anything that has been treated with a pesticide including soil, air, water and the surface of plants where pesticide residues may be found before any restricted-entry interval (REI) for the pesticide has expired. The original WPS had no age minimum.
The other major changes to the standard that the EPA highlights include:
- Annual mandatory training to inform farmworkers on the required protections afforded to them. Currently, training is only required once every 5 years.
- Expanded training includes instructions to reduce take-home exposure from pesticides on work clothing and other safety topics.
- Expanded mandatory posting of no-entry signs for the most hazardous pesticides. The signs prohibit entry into pesticide-treated fields until residues decline to a safe level.
- New no-entry application-exclusion zones up to 100 feet surrounding pesticide application equipment to protect workers and others from exposure to pesticide overspray.
- Requirement to provide more than one way for farmworkers and their representatives to gain access to pesticide application information and safety data sheets (SDS) – centrally posted or by requesting records.
- Mandatory record keeping to improve states’ ability to follow up on pesticide violations and enforce compliance. Records of application-specific pesticide information, as well as farmworker training, must be kept for two years.
- Anti-retaliation provisions comparable to that of the Department of Labor (DOL).
- Changes in personal protective equipment (PPE) consistent with DOL’s standards for ensuring respirators are effective, including fit test, medical evaluation and training.
- Specific amounts of water to be used for routine washing, emergency eye flushing and other decontamination, including eye wash systems for handlers at pesticide mixing/loading sites.
- Continued the exemption for farm owners and their immediate families with an expanded definition of immediate family.
