When may workers re-enter an area after pesticide application, and what conditions apply?

• A. Immediately after application, regardless of label.
• B. Only after sunset.
• C. After the REI has elapsed or as specified on the label; if required, wear specified PPE or obtain authorization per the label.
• D. Never re-enter after application.

Answer: (C)

Re-entry timing is controlled by the product’s restricted-entry interval (REI) and the label directions. After an application, workers may re-enter only after the REI has elapsed or as the label specifies. If the label requires it, you must wear the PPE listed for entry or obtain authorization per the label before entering. This protects workers from exposure to residues that may still be hazardous, and the label sets legally binding conditions you must follow. Sunset or entering immediately after application isn’t a safe or legal rule because it ignores the specific REI and PPE requirements on the label.
