Which of the following actions is NOT a recommended first aid step for pesticide on the skin?

Applying lotion immediately to skin contaminated with pesticides is not a recommended first aid step. The rationale behind this is that lotions and creams can potentially trap the pesticide against the skin, limiting the effectiveness of cleansing the affected area. Immediately applying lotion could hinder the process of removing the pesticide and may worsen the situation by preventing the skin from being adequately rinsed and cleaned.

In contrast, removing contaminated clothing is important to prevent further exposure, drenching the skin with cold water helps to dilute and wash away any chemicals, and seeking professional medical attention ensures that any necessary medical intervention is provided, especially if the exposure could lead to serious health issues. Proper first aid focuses on minimizing harm and ensuring thorough decontamination, which is why the immediate application of lotion is not a suitable choice in this scenario.
