When a person has been poisoned by gases, what is the immediate action?

In cases of poisoning by gases, the immediate action that should be taken is to quickly remove the victim into fresh air. This is crucial because exposure to toxic gases can lead to rapid deterioration of the victim’s condition, as many gases can displace oxygen in the lungs or cause immediate harm upon inhalation. Securing fresh air minimizes further exposure to the harmful substances, which is the most urgent priority.

Other options, while important in managing the overall situation, are secondary to the immediate need for fresh air. For instance, starting artificial respiration and administering oxygen can be life-saving actions, but these should only be carried out once the person is safe from further inhalation of the toxic substance. Calling for emergency services is essential for long-term care, but immediate first aid must focus on removing the victim from the hazardous environment.
