What should be done for ingestion of pesticides if the person is conscious and alert?

When a person has ingested pesticides and is conscious and alert, it is crucial to dilute the substance to minimize its absorption in the gastrointestinal tract. Giving large amounts of water or milk serves this purpose effectively. The dilution helps to reduce the concentration of the pesticide, which can lessen its potential toxic effects on the body.

Providing water or milk provides a safer alternative to inducing vomiting, which can be harmful and may cause additional complications, such as aspiration or further injury to the esophagus. Administering activated charcoal may be appropriate in certain circumstances, but it is typically reserved for specific situations and usually requires medical supervision. Waiting for symptoms to pass is not advisable, as this approach does not address the immediate risk posed by the poison.

Thus, diluting the pesticide with water or milk is the correct and safest initial step when dealing with conscious and alert individuals who have ingested pesticides.
