Who is responsible for posting warning signs regarding the REI around treated fields?

The operator of the property is responsible for posting warning signs regarding the Restricted Entry Interval (REI) around treated fields. This responsibility falls on the operator because they are in direct control of the site where the pesticide application takes place and are responsible for ensuring compliance with safety regulations related to pesticide use.

Posting warning signs is crucial for keeping workers informed about the safe re-entry times after pesticides have been applied, which helps prevent exposure to potentially harmful chemicals. The operator must follow the specific requirements outlined in the law and label directions regarding the timing and placement of these signs.

The other entities mentioned, such as the property owner or the pesticide applicators, may play important roles in the overall pesticide application and safety process, but the legal responsibility for warning sign placement specifically lies with the operator who manages the day-to-day operations on the property. Local regulatory agencies focus on enforcement and compliance monitoring rather than the direct responsibilities of posting signs on specific properties.
