What document must be displayed at the work site or central location when fieldworkers are working in a pesticide-treated field?

The correct choice is the completed Pesticide Safety Information Series leaflet A-9, which must be displayed at the worksite or a central location when fieldworkers are in a pesticide-treated area. This document serves a vital purpose in communicating important safety information regarding the pesticides used at the site. The leaflet contains essential details on what to do in case of exposure, signs and symptoms of pesticide poisoning, proper handling techniques, and emergency response actions.

Having this leaflet prominently displayed ensures that all fieldworkers have immediate access to crucial safety information, helping to promote a safe working environment and minimizing the risk of pesticide-related incidents. Displaying this information is a regulatory requirement, emphasizing its importance in protecting worker health and safety in agricultural settings.

The other options, while related to safety and training, do not fulfill the specific obligation to display a document in a pesticide-treated field context. They serve different purposes, such as providing training outlines or listing workers, but they do not directly convey immediate safety information necessary for the workers in that particular environment.
