Early Entry and a Sick Worker in Blueberries
On July 8 at 5:30 a.m. a licensed applicator sprays a 60-acre blueberry field near Salem with an insecticide labeled with a 96-hour restricted-entry interval, double notification, and a requirement that handlers wear chemical-resistant gloves and coveralls. The fruit is softening and a heat wave is forecast, so the grower wants his 18-person hand-harvest crew back in the field on July 10, roughly 52 hours after the application. None of the crew has had WPS training this year; the grower plans to tell them to "stay out of the sprayed rows" and to post a sign at the gate. The nearest decontamination supplies are a 20-gallon drum and a bar of soap at the shop, about 300 yards from the field. On July 10 a 24-year-old picker who entered anyway complains of headache, sweating, blurred vision, and muscle twitching; the foreman gives him water and tells him to rest in the truck until lunch.
1. May the crew hand-harvest on July 10? Justify your answer against the label and the Worker Protection Standard.
Read the worked answer
No. Three independent reasons, and the market pressure is irrelevant to all of them.
- The REI has not expired. A 96-hour REI runs from the end of the application. July 10 at 5:30 a.m. is 48 hours; even the "roughly 52 hours" is well inside 96 hours.
- Early entry does not cover hand labor. The Worker Protection Standard allows early entry during an REI only for short-term, limited-contact activities (for example, certain irrigation or scouting tasks) performed with the specific PPE listed in the WPS early-entry PPE table, by trained workers, with decontamination supplies readily available. Hand harvesting is hand labor and is not an early-entry activity at any PPE level.
- Posting is not a substitute. A sign at the gate communicates the REI; it does not shorten it, and it does not authorize entry.
The realistic options are to wait out the REI, to plan ahead and choose a product with a shorter REI for near-harvest timing, or to shift crews to untreated blocks. Promising a crew they can pick early is a management failure, not a compliance strategy - and if they entered, the field is now a potential exposure scene rather than a harvest site.
2. What should happen to the symptomatic worker, and what reporting and recordkeeping obligations follow?
Read the worked answer
Treat the symptoms as a possible pesticide poisoning emergency, not as heat exhaustion.
Clinical reasoning: headache, sweating, blurred vision, and muscle twitching after entering a just-treated field are consistent with cholinesterase-inhibiting insecticide exposure (organophosphate or carbamate). The combination of secretory symptoms and twitching raises concern for a serious cholinergic crisis, and it can worsen quickly.
Immediate actions:
- Remove him from the field, remove contaminated clothing, and wash skin with soap and water.
- Do not leave him alone; never send a symptomatic worker to drive himself.
- The employer provides transportation to emergency medical care immediately, with the product label and SDS.
- Do not induce vomiting or give anything by mouth; the label and medical staff govern treatment.
Afterwards: document the incident, times, product, and REI status; notify ODA, which operates the state's pesticide incident reporting channel (PARC), and be aware that treating physicians have reporting duties for pesticide illness; record it on the OSHA injury log if recordable. Preserve the spray record, weather data, and the crew's entry times. Do not discourage the worker from seeking care or discussing it - retaliation against a worker who reports an exposure is prohibited and converts an incident into a much larger case.
3. List the WPS deficiencies in this operation and the fixes that must be in place before the next application.

Go requirement by requirement and compare to what exists:
- Training: workers must be trained before working in an area with an REI, and retrained at least every 12 months. None have been trained this year. Fix: WPS-approved training for all 18, documented with names and dates.
- Notification: the label required double notification - both posted and oral - and the grower planned neither. Fix: post the required information at the central location and give oral notification before the application, with the REI end time.
- Decontamination supplies: must be within a quarter mile of workers, with enough water for routine washing and emergency eye flushing (at least one gallon per worker for workers, more for handlers), soap, and single-use towels. A drum and a bar of soap 300 yards away fails both the distance and the adequacy tests.
- Early-entry handling: no trained early-entry workers, no required PPE on hand, no supervision. Fix: designate and equip early-entry personnel or simply forbid entry.
- Information and records: the application information (product, EPA number, time, REI) must be available at the central posting location; training and notification records must be kept.
Practical fix: build a pre-application checklist that requires the label REI, the notification type, the training roster, and the supply cart to be confirmed before the tank is filled.
