Before fieldworker employees are allowed to enter pesticide-treated fields, what information must the operator of the property inform them about?

The operator of the property is required to inform fieldworker employees about the availability and location of pesticide use records and Safety Data Sheets (SDS) before they enter pesticide-treated fields. This information is crucial because it enables fieldworkers to understand the specific pesticides that have been applied, including their potential hazards and safe handling practices. Access to pesticide use records ensures that fieldworkers are informed about what products were used, their application rates, and any relevant safety information, including personal protective equipment (PPE) requirements.

Safety Data Sheets provide essential information on the chemical properties of the pesticides, health effects, and emergency measures in case of exposure, thus equipping workers with the knowledge necessary to protect their health while working in potentially hazardous environments. This requirement to inform ensures that fieldworkers are adequately prepared and can take appropriate precautions to avoid exposure, emphasizing worker safety as a priority in pesticide use enforcement.

The other options, while they may contain relevant information related to pesticides, do not cover the comprehensive requirement of informing workers about the availability of records and safety data sheets specifically.
