What is the maximum distance that posting signs must be placed apart when notifying about a pesticide REI?

The maximum distance that posting signs must be placed apart when notifying about a pesticide Restricted Entry Interval (REI) is 600 feet. This requirement is established to ensure that individuals entering or working near treated areas are adequately informed of the potential hazards associated with pesticide applications.

By placing signs at this distance, it helps to maximize visibility and awareness, ensuring that workers and the public can easily see the signage, regardless of how far they may be from the pesticide application site. The REI is a critical safety measure designed to minimize exposure to chemicals after application, and proper signage ensures compliance with regulations aimed at protecting both human health and the environment.

In contrast, the other distances mentioned could lead to insufficient notification, potentially putting individuals at risk by failing to adequately inform them of the REI, which could increase the likelihood of pesticide exposure. Hence, having the signs set at a maximum of 600 feet reflects best practices in pest control safety regulations.
