What action must be taken when there is an inconsistency between the regulation-specified REI and the label-specified REI?

When there is an inconsistency between the regulation-specified Restricted Entry Interval (REI) and the label-specified REI, the correct course of action is to adhere to the longer interval. The REI indicates the minimum amount of time that must pass after a pesticide application before workers can re-enter the treated area without protective gear. This is critically important for ensuring worker safety.

By using the longer REI, you are taking into account the possibility that the longer interval is necessary to reduce exposure risk and ensure that any residues have sufficiently degraded. Regulatory bodies establish these REIs based on factors such as toxicity data and environmental conditions. Therefore, when faced with conflicting information, prioritizing the longer is in line with best practices for safety, adhering to both regulatory standards and precautionary principles.

This approach is not only in compliance with safety regulations but also reflects a commitment to protecting human health and the environment by minimizing exposure to potentially harmful substances.
