When using posting as a method of notification about a pesticide REI, how far apart must posting signs be placed at a minimum?

When notifying about a pesticide's Restricted Entry Interval (REI) through posting, the requirement is that posting signs must be placed a minimum of 600 feet apart. This distance ensures adequate visibility and communication to those who may be entering or working in the treated area. The purpose of such regulations is to protect workers and the public from exposure to potentially hazardous chemicals by clearly marking boundaries and informing individuals of the necessary precautions.

A distance of 600 feet helps guarantee that even if one sign goes unnoticed, another will be within a reasonable range, thereby enhancing safety and compliance with the regulations. The specifics of these distances are established to provide a consistent standard across different agricultural locations, ensuring that all areas treated with pesticides are adequately marked and that the REIs are respected by anyone who may be in the vicinity.
