The correct choice emphasizes that any symptoms appearing while or shortly after working should raise concerns about potential pesticide exposure. This is crucial because the timing of symptoms in relation to pesticide application is a key indicator of exposure. Many pesticide-related health effects can manifest rapidly, and early recognition of symptoms allows for swift action to mitigate further exposure and seek medical attention if necessary.

Symptoms might include respiratory issues, skin irritation, or gastrointestinal complaints, which can arise as a direct response to handling or being in proximity to pesticides. Recognizing these symptoms promptly can help in taking appropriate safety measures, such as decontamination and reporting, and can play a vital role in preventing more severe health effects.

The other options do not adequately address the immediate safety concerns associated with pesticide exposure. A symptom-free period after working does not confirm that no exposure occurred, while mild headaches alone do not necessarily warrant concern without accompanying symptoms or context. Lastly, symptoms persisting for more than a day indicates a potential issue but may not lead to immediate action required upon first noticing symptoms. Thus, it's essential to remain vigilant at the onset of any symptoms during or shortly after pesticide application.
