Who is permitted to enter a site during a restricted entry interval (REI)?

During a restricted entry interval (REI), it is critical to protect individuals from potential exposure to toxic levels of pesticides that may linger in the environment following application. The answer highlighting that only personnel wearing the required personal protective equipment (PPE) are permitted to enter reflects an important safety measure.

Those allowed entry under these circumstances are typically trained and equipped to mitigate any potential risks associated with pesticide exposure. Wearing appropriate PPE—such as gloves, masks, respirators, and protective clothing—reduces the likelihood of harmful absorption through the skin or inhalation of pesticide residues.

In contrast, anyone who wants to inspect the application would not have adequate training or protection, which could endanger their health. Neighbors might be interested in what is happening on the property but have no protective measures in place, putting them at risk if they enter the area. Similarly, while certified pesticide applicators have training, they are still subject to REI restrictions and must also be equipped with the required PPE if they enter during this period, thus further confirming that the answer prioritizes safety and compliance with pesticide application guidelines.
