Can workers enter a treated area during the REI?

The correct answer is that workers can enter a treated area during the Restricted Entry Interval (REI) only with proper early-entry personal protective equipment (PPE), if allowed. This requirement is crucial because the REI is the period following the application of a pesticide during which entry into the treated area is restricted to protect workers from potential exposure to harmful residues.

In certain situations, regulations may permit entry into a treated area if specific wearables and equipment are used to minimize exposure risks. This is typically applicable in scenarios where there are agricultural practices that necessitate immediate attention, and where safe entry protocols have been established. Therefore, having proper PPE is essential for safeguarding the health of those who may need to enter the area.

The other choices do not align with safety regulations governing pesticide applications. Allowing entry at any time without restrictions compromises worker safety, while absolute prohibition ignores potential necessary interventions that could require safe access with proper precautions. Ventilation does not address the need for protective equipment, which is central to ensuring health and safety standards are met.
