How can the amount of exposure from a spilled pesticide on the arm often be reduced?

Washing the exposed area with soap and water is the most effective method for reducing exposure from a spilled pesticide on the arm. This method not only removes the pesticide from the skin but also helps to break down its chemical components, thereby minimizing the risk of absorption into the body. Soap acts as a surfactant, which enhances the removal of contaminants by binding to the pesticide molecules and allowing them to be washed away.

This is important because pesticides can be harmful through skin contact, and thorough cleansing is critical in lessening potential health risks. While wiping the liquid off may seem helpful, it may not effectively remove all traces of the pesticide and could potentially spread it to other areas of the skin. Similarly, covering the area with a damp cloth may prevent further exposure but does not remove the pesticide itself, and using antibacterial wipes may not be designed to neutralize chemical contaminants like pesticides. Thus, washing with soap and water remains the best practice in such scenarios.
