What is the first step to take for someone with inhalation exposure to pesticides?

The most appropriate first step for someone who has inhaled pesticides is to get the victim into fresh air. This action is crucial because it helps to immediately reduce or eliminate further exposure to the harmful chemicals. Fresh air can dilute the concentration of pesticides in the victim's breathing zone, facilitating easier breathing and decreasing the chances of further respiratory distress.

Other interventions, such as starting CPR or giving water, may be necessary under certain circumstances, but they are not the immediate priority in the case of inhalation exposure. Also, moving the victim into a cold environment could lead to additional stress on the body and is not beneficial in this context. The primary focus must be on removing the individual from the contaminated air to mitigate the effects of the pesticide exposure as quickly as possible.
