What is the first step to take after an acute, dermal exposure to a moderately or highly toxic pesticide?

After an acute, dermal exposure to a moderately or highly toxic pesticide, the first step is to remove contaminated clothing and shower. This action is crucial because it minimizes further absorption of the pesticide into the skin and reduces the risk of additional exposure. Contaminated clothing can continue to release toxins onto the skin, exacerbating the situation.

Taking a thorough shower with soap and water helps to wash away any pesticide residues that may still be on the skin, thereby preventing potential poisoning and further irritation. Quick and decisive action in this regard is an essential part of first aid for pesticide exposure, as it significantly mitigates health risks.

Calling poison control or waiting for symptoms may be necessary later, but immediate physical decontamination is vital. Applying ointment is generally inappropriate after pesticide exposure, as it might trap chemicals against the skin rather than help in their removal. Therefore, prioritizing the removal of contaminated clothing and cleansing the area is the most effective first response in these situations.
