When applying pesticides, which of the following is a key safety precaution?

Wearing protective gear is crucial when applying pesticides to ensure safety from chemical exposure. This gear typically includes items such as gloves, goggles, masks, and long-sleeved clothing, which serve to create a barrier between the pesticide and the skin, eyes, and respiratory system. The use of protective gear significantly minimizes the risks associated with handling potentially hazardous substances, helping to prevent skin irritation, respiratory issues, and other health problems that can result from direct contact or inhalation.

In contrast, wearing sandals provides little protection, as they do not shield the feet or skin from pesticide splashes or spills. Making sure the area is dark does not contribute to safety and could increase the likelihood of accidents or misapplication. Leaving windows open for ventilation might seem beneficial, but it can also allow drift of the pesticide to unintended areas or expose others to harmful chemicals. Thus, employing protective gear is the most effective measure to ensure personal safety during pesticide application.
