Why is it important to wear protective clothing while spraying pesticides?

Wearing protective clothing while spraying pesticides is essential because pesticides can be absorbed into the skin upon contact. Many pesticides contain toxic chemicals that can lead to serious health issues if they penetrate the skin. Proper protective gear, such as gloves, long sleeves, masks, and goggles, acts as a barrier to prevent this absorption and minimizes the risk of exposure to harmful substances. This protective measure is fundamental to ensuring not only the safety of the individual applying the pesticide but also the overall health of the environment and surrounding areas where the pesticides are used.

The other options, while they may seem relevant, do not directly address the primary concern of preventing chemical exposure. For instance, while avoiding heat exhaustion is important in general outdoor work, it is not the primary reason for wearing protective clothing in this context. The focus should be on the chemical safety and preventing absorption through the skin.
