1.3 The Worker Protection Standard in Ohio
Key Takeaways
- Ohio has adopted the federal Agricultural Worker Protection Standard (40 CFR Part 170) as the pesticide safety standard for the state under OAC 901:5-11-19.
- WPS separates agricultural workers, who perform hand labor in treated areas, from pesticide handlers, who mix, load, apply, or maintain application equipment.
- Handlers must be at least 18 years old, and both workers and handlers must receive WPS training before entering a treated area or handling pesticides.
- Decontamination supplies require at least 1 gallon of water per worker and 3 gallons per handler, plus soap, single-use towels, and clean coveralls for handlers.
- The application exclusion zone travels with the equipment and requires the handler to suspend the application if anyone other than a trained handler enters it.
1.3 The Worker Protection Standard in Ohio
The Agricultural Worker Protection Standard (WPS), codified at 40 CFR Part 170, is the federal rule that protects people who work on farms, forests, nurseries, and greenhouses that produce agricultural plants. Ohio did not write its own version. Under OAC 901:5-11-19 the Ohio Department of Agriculture adopts 40 CFR Part 170 as the pesticide safety standard for Ohio, including all of its exemptions and exceptions. That means WPS is enforced in Ohio by ODA inspectors under state law, and the Core exam treats it as Ohio law.
Who WPS Covers - and Who It Does Not
WPS applies where agricultural plants are produced for commercial or research purposes. It does not apply to structural pest control inside a building, to turf on a golf course or lawn, to right-of-way vegetation management, to livestock treatments, or to a homeowner's garden.
Within a covered establishment, WPS divides people into two roles:
| Role | What they do | Key protections |
|---|---|---|
| Agricultural worker | Hand labor in a treated area: harvesting, weeding, pruning, thinning, transplanting, moving irrigation. | WPS training before entry, notification of treated areas, restricted-entry interval compliance, decontamination supplies. |
| Pesticide handler | Mixes, loads, applies, cleans or repairs application equipment, acts as a flagger, or handles opened containers. | Minimum age 18, WPS handler training, label PPE, respirator fit test/medical evaluation/training, handler decontamination, application-monitoring. |
The Employer's Core Duties
- Training. Workers and handlers must be trained with EPA-approved WPS materials before they work in a treated area or handle pesticides, and retrained at least every 12 months.
- Central posting. A single accessible location must display the EPA WPS safety poster, the name, address, and telephone number of the nearest emergency medical facility, and application-specific information for every pesticide applied on the establishment, posted before the application starts and kept for 30 days after the restricted-entry interval expires. The application record includes the location and description of the treated area, product name, EPA registration number, active ingredient, application date and start/end times, and the REI.
- Notification. Workers must be kept out of treated areas during the REI. Depending on what the label requires, the employer gives oral warnings, posts the treated area with the standard WPS sign, or both. The sign carries the words "DANGER / PELIGRO - PESTICIDES / PESTICIDAS - KEEP OUT / NO ENTRE" with the stop-hand symbol.
- Restricted-entry interval (REI). The REI is the label-set period after an application during which entry into the treated area is limited. Early entry is allowed only in narrow circumstances, and early-entry workers must be at least 18, trained, and wearing the early-entry PPE the label specifies.
- Decontamination supplies. Within a quarter mile of workers and handlers (or at the mixing and loading site) the employer must supply water, soap, and single-use towels.
| Supply | Agricultural worker | Pesticide handler |
|---|---|---|
| Water for routine washing and emergencies | At least 1 gallon per worker | At least 3 gallons per handler |
| Soap and single-use towels | Required | Required |
| Clean change of coveralls | Not required | Required at the handler decontamination site |
| Eyewash - immediate gentle-flow water for 15 minutes | Only if the label requires protective eyewear for early entry | Required where the label requires protective eyewear or a closed system operating under pressure |
- Emergency assistance. If a worker or handler may have been poisoned or injured by a pesticide, the employer must promptly provide transportation to an emergency medical facility and supply the product name, EPA registration number, active ingredients, the SDS, the antidote information, and a description of how the exposure happened.
The Application Exclusion Zone
The application exclusion zone (AEZ) is the area that moves with the application equipment during the application itself. Its size depends on the equipment and spray quality - up to 100 feet for aerially applied, air-blast, air-propelled, fumigant, smoke, mist, or fog applications, and 25 feet for many ground sprays released above 12 inches.
The rule for the applicator is simple and heavily tested: suspend the application if any person other than an appropriately trained and equipped handler is in the AEZ. The duty falls on the person operating the equipment, and it applies to bystanders as well as employees.
Practical Ohio Overlap
WPS obligations sit alongside, not instead of, Ohio's own rules. A commercial applicator treating a nursery in Ohio simultaneously owes WPS duties to the nursery's workers, ODA recordkeeping duties under OAC 901:5-11-10, and the direct-supervision duties in OAC 901:5-11-02 for any trained serviceperson on the crew.
