How can a person reduce the injury caused by spilling liquid pesticide on his or her arm?

Washing the exposed area with soap and water is the most effective response to minimize injury from spilled liquid pesticide on the skin. This immediate action helps to remove the pesticide before it can be absorbed by the skin, thereby reducing the potential for irritation or harmful effects. Soap aids in breaking down the chemicals, allowing for a thorough cleansing process that can significantly lessen any adverse reactions.

While other options might provide some benefits, they do not directly address the need to cleanse the skin from pesticide exposure. For instance, applying sunscreen is intended for protection against UV rays and does not neutralize or remove chemicals. Using a cold pack may alleviate any resulting irritation or pain but does not prevent injury from the pesticide itself. Similarly, applying a topical ointment might soothe the skin after irritation occurs, but it does not prevent any initial damage caused by the pesticide. Thus, washing with soap and water stands out as the critical first step in managing pesticide exposure.
