After an acute, dermal exposure to a highly toxic pesticide, what is the first recommended action?

After an acute, dermal exposure to a highly toxic pesticide, the first recommended action is to remove contaminated clothing and shower. This priority action helps to minimize further exposure to the pesticide, which can continue to affect the skin and potentially enter the bloodstream if left untreated. Quickly removing contaminated clothing is crucial, as it can retain the pesticide, prolonging contact with the skin and increasing the risk of toxic effects.

Showering with soap and water will remove the pesticide from the skin, significantly reducing the chance of absorption and mitigating the health risks associated with the exposure. This action should be taken as quickly as possible after the exposure to enhance safety and limit adverse effects.

The other options listed, while related to exposure responses, do not address the immediate need to eliminate contact with the harmful substance effectively. Drinking water may be helpful in some poisoning situations, but it does not help with dermal exposure. Inducing vomiting can lead to complications and is generally discouraged without specific medical direction, particularly for substances that might cause harm upon ingestion or if the person is not fully conscious. Continuing to spray and then going home avoids addressing the immediate danger and can lead to further issues for both the applicator and others nearby.
