A supply of clean water, soap, and a basin is most helpful in which type of pesticide exposure?

The availability of clean water, soap, and a basin is most beneficial in the case of dermal pesticide exposure. When pesticides come into contact with the skin, it is crucial to promptly wash the affected area to reduce the risk of absorption and potential health effects. The use of soap in conjunction with water helps to effectively remove the pesticide residues from the skin.

In situations of oral pesticide exposure, the appropriate response typically involves seeking medical assistance immediately rather than simply washing the mouth with water. For inhalation exposure, quick removal from the contaminated environment is essential, and while rinsing the mouth may be helpful, it does not play a significant role in addressing the issue itself compared to the immediate steps necessary for respiratory distress or exposure.

Thus, the combination of clean water, soap, and a basin specifically addresses the need to cleanse the skin effectively following dermal contact with pesticides, making it the most suited option in this context.
