Which of the following is not an employer responsibility before allowing employees into a treated field after pesticide application?

The reason why the first option is the correct answer lies in the specific regulatory requirements and responsibilities placed on employers concerning agricultural workers and pesticide applications. Before allowing employees into a treated field, employers must focus on immediate safety and hazard communication related to the pesticide exposure, rather than personal protective equipment (PPE) storage at home.

Informing workers about the pesticides used, their associated hazards, and conducting safety briefings directly addresses immediate safety concerns that are crucial for workers' protection upon entering treated areas. Ensuring that workers wear the required protective gear is a direct responsibility that safeguards their health from potential pesticide exposure, aligning with workplace safety standards.

The requirement to provide instructions about home storage of PPE is not a pertinent aspect of ensuring worker safety in the immediate context of entering treated fields. It is more relevant to general maintenance of equipment rather than the critical pre-entry safety protocols required upon returning to a treated environment.
