What should you do if a person has swallowed a fumigant?

If a person has swallowed a fumigant, the appropriate action is to give them large amounts of water if they are alert. This is crucial because it can help dilute the toxic substance in the stomach and mitigate its harmful effects. It is important, however, that the person is alert and able to swallow safely; otherwise, providing fluids could risk choking or aspiration.

Inducing vomiting is generally not recommended as it can lead to further complications, such as aspiration of the chemical back into the lungs. Offering a cookie or a hot drink does not serve any beneficial purpose in treating the ingestion of a toxic substance and could further complicate the situation. The focus should always be on minimizing harm and ensuring the person's safety first. Therefore, offering water as a dilution method is the most appropriate response, as long as specific medical advice has not been provided against that action for the particular fumigant involved.
