Worker employers must keep everyone except appropriately trained and equipped handlers out of areas being treated with pesticides.

In nurseries and greenhouses, employers must also keep workers and other persons out of the area immediately around the area being treated during some applications. This is known as the entry-restricted area. The size of the entry-restricted area or "keep-out zone" depends on the pesticide used and the application method. Read more about the requirements for entry-restricted areas at nurseries and greenhouses in Unit 4 of the How to Comply Manual.
