What is a restricted-entry interval (REI)?

The correct answer identifies the restricted-entry interval (REI) as the time after pesticide application when entry is restricted. This is a critical safety measure designed to protect workers, by ensuring they do not enter treated areas until it is safe to do so. The REI is established based on the toxicity of the pesticide used and the potential risks to human health. It takes into account factors such as the time it takes for pesticide residues to dissipate to a level that is considered safe for unprotected workers.

In practice, the REI can vary significantly depending on the pesticide and the application method. Following the REI helps to minimize the risk of exposure to harmful chemicals, protecting agricultural workers and ensuring compliance with regulatory standards. Understanding and adhering to REI guidelines is essential for safe pesticide use and worker safety in agricultural settings.
