DEVELOPMENT OF THIS GUIDE WAS SUPPORTED IN PART BY THE STATE OF HAWAII DEPARTMENT OF AGRICULTURE.
The Worker Protection Standard or WPS is a federal regulation that requires agricultural employers to protect their agricultural employees from pesticides (including herbicides) used to produce agricultural plants in the U.S. The WPS is mainly about protecting employees who will handle the pesticides or who will work in or near areas treated with the pesticides. The employees need protection from the pesticides in diluted mixtures, fumes, dust, spray drift, or residue in soil, in water, or on the treated plants and from the pesticide products themselves.
A handler is an employee who does any of the following tasks:
- Mix, load, transfer, or apply pesticides.
- Handle opened containers of pesticides.
- Act as a “flagger.”
- Clean, handle, adjust, or repair the parts of mixing, loading, or application equipment that may contain pesticide residues.
- Assist with the application of pesticides, including incorporating the pesticide into the soil after the application has occurred.
- Enter a greenhouse or other enclosed area after application and before the inhalation exposure level listed on the product labeling has been reached or one of the worker protection standard (WPS) ventilation criteria has been met to operate ventilation equipment; adjust or remove coverings, such as tarps, used in fumigation; or check air concentration levels, entering a treated area outdoors after application of any soil fumigant to adjust or remove soil coverings, such as tarpaulins.
- Perform tasks as a crop advisor during any pesticide application, and before any inhalation exposure level or ventilation criteria listed in the labeling has been reached or one of the WPS ventilation criteria has been met during any restricted-entry interval.
- Dispose of pesticides or pesticide containers.
A farm mechanic could be a handler if he or she works on pesticide application equipment but does not apply a pesticide.
A worker is an employee who performs activities directly relating to the production of agricultural plants, such as repotting plants, weeding, pruning, irrigating, and harvesting.
An employee may act as a handler and later act as a worker.
An agricultural employer could be any of these three: an owner of an operation producing the agricultural plants, a person responsible for the management or condition of such an operation, or a labor contractor who places a laborer at such an operation.
A small-farm owner may act as the employer, the handler, or the worker in different situations.
The Worker Protection Standard applies to you, as an agricultural employer, if all three of the following are true:
- Someone uses a pesticide in the production of agricultural plants at your farm, commercial forest, nursery, greenhouse, or other enclosed space or outdoor production area; and,
- The plants being produced are agricultural plants, which are plants grown or maintained for commercial or research purposes, for example, plants grown for their fruits, nuts, vegetables, melons, taro, corn or any other grain; mushrooms, edible sprouts, herbs, tobacco, beverages, spices, lumber, pulp, fiber, fuel, foliage, or flowers; and ornamental trees, shrubs, turfgrasses or other groundcovers to be transplanted; and,
- The pesticide is an agricultural pesticide. This type of pesticide has a label with a box of statements titled “AGRICULTURAL USE REQUIREMENTS” like this:
An employee of a government agency, educational institution, or a nonprofit organization may be covered by the WPS rules if he or she is involved in producing “agricultural plants” even if the operation is not commonly thought of as “agricultural.”
A custom applicator or for-hire pesticide applicator must comply with the WPS rules when he or she provides service as a handler at an operation where the WPS applies.
A pest management advisor and family members who help on a family farm must comply with some of the WPS requirements.
But the WPS does not apply to the following pesticide uses even if they occur on agricultural sites:
- Government-sponsored public pest control programs over which the owner, agricultural employer and handler employer have no control (e.g., mosquito abatement and Mediterranean fruit fly eradication programs),
- Use on plants other than agricultural plants, including plants in home fruit and vegetable gardens and home greenhouses, and permanent plantings for ornamental purposes, such as plants that are in ornamental gardens, parks, public or private landscaping, lawns or other grounds that are intended only for aesthetic purposes or climatic modification,
- Use for control of vertebrate pests, unless directly related to the production of an agricultural plant,
- Use as attractants or repellents in traps,
- Use on the harvested portions of agricultural plants or on harvested timber (e.g., wood preservation and post-harvest or stored commodity applications),
- Research uses of unregistered pesticides,
- Use on pasture and rangeland where the forage will not be harvested for hay, and
- Use in a manner not directly related to the production of agricultural plants, including, but not limited to livestock pest control (e.g., pesticide applications on livestock or other animals or in or about animal premises), structural pest control and control of vegetation in non-crop areas.
If the WPS applies at your enclosed space or outdoor production area, you should read the “How to Comply Manual.” It explains what agricultural employers must do to comply with the WPS rules. You should study the manual if you are planning to take one of the Hawaii Department of Agriculture’s restricted use pesticide certification exams for any of these categories of pesticide applicators: Private 1, Commercial 1a, Commercial 2, Commercial 3, Commercial 4, or Commercial 10. The manual is available as a free, downloadable electronic file for computers and as a paper booklet. For more information about getting the manual, telephone 808-956-6007 or use a computer to follow the links for one of those categories starting at:
