What should be done if someone inhales a harmful chemical?

If someone inhales a harmful chemical, the most appropriate action is to move them to fresh air and seek medical attention if necessary. This response is crucial because inhaling chemicals can lead to immediate and serious health effects, such as respiratory distress or chemical exposure injuries.

By moving the affected person to an area with clean air, you can help mitigate the adverse effects of the inhaled substance. Fresh air allows their lungs to receive oxygen without the harmful effects of the chemical, thus stabilizing their condition initially. If symptoms persist or worsen, seeking medical attention becomes necessary to ensure they receive appropriate care and treatment.

The other options do not address the immediate need for fresh air or appropriate medical response. Giving water to drink may not aid the situation, especially if the chemical is toxic or can react adversely with water. Administering oxygen may be an appropriate step in some circumstances, but it must be done by trained individuals, especially when considering the potential risks involved with the specific chemical. Continuing to work with the chemical poses additional risks, both to the person affected and to others nearby, as it ignores the gravity of inhaling a harmful substance.
