When must warning signs for the REI be posted before an application?

Warning signs for the Restricted Entry Interval (REI) must be posted 24 hours before an application of pesticides. This requirement is established to ensure that individuals entering the treated area are adequately informed of the potential hazards associated with the pesticide application. By posting the signs in advance, there is an opportunity for the area to be visually marked, helping to prevent inadvertent exposure to chemicals that may pose health risks.

Posting the signs 24 hours in advance allows for proper visibility and gives workers a reasonable timeframe to understand the precautions necessary before they potentially enter the area. This practice not only supports compliance with regulations but also enhances safety awareness among workers and the surrounding community.
