How can the amount of exposure and injury from a pesticide spill on the arm often be reduced?

Washing the exposed area with soap and water is the most effective method for reducing exposure and injury from a pesticide spill on the skin. This method works by physically removing the pesticide from the skin's surface, thus decreasing the likelihood of absorption into the body, which can lead to potential health risks such as irritation, allergic reactions, or more severe toxic effects.

Promptly washing the area also helps to dilute any remaining pesticide and can significantly minimize skin irritation or burns that might develop from prolonged contact with the chemical. Infrastructure such as emergency showers and eye wash stations are often recommended in agricultural and industrial settings precisely for this purpose, emphasizing the importance of immediate decontamination.

While applying ice to the area might reduce pain or swelling, it does not eliminate the pesticide from the skin. Covering the area with a bandage can trap the chemical against the skin, potentially worsening the exposure rather than mitigating it. Additionally, waiting for the pesticide to dry is not advisable, as this could result in increased absorption and greater risk of injury.
