Name a safety practice when handling pesticides.

Wearing personal protective equipment (PPE) is a critical safety practice when handling pesticides because it significantly reduces the risk of exposure to potentially harmful chemicals. PPE may include gloves, masks, goggles, and protective clothing, all designed to shield the skin, respiratory system, and eyes from pesticide splashes, dust, or vapors. Proper use of PPE is essential for ensuring the safety of the person applying the pesticide, as well as those nearby.

The other options, while relevant to pesticide safety, do not directly contribute to the immediate personal safety of the handler in the same way. Using only approved pesticides is crucial for efficacy and legal compliance, but it does not address the exposure risk directly. Applying pesticides in the evening might mitigate drift to non-target areas due to calmer winds, but it doesn't protect the handler from exposure. Storing pesticides in a cool place is important for maintaining the product's effectiveness and preventing degradation, but does not provide immediate safety during the handling process.
