What should be done immediately when two occupants report headache and dizziness?

When two occupants report symptoms such as headache and dizziness, the immediate priority is to assist them in leaving the affected area. These symptoms can be indicative of potential exposure to carbon monoxide or other hazardous substances, which in high concentrations can cause serious health risks. Ensuring the safety of the individuals is crucial; getting them to a location with fresh air is a vital first step.

Assisting the occupants to exit the area helps to mitigate their exposure to whatever is causing these symptoms, thereby preventing further harm. While other options like shutting off gas appliances or evacuating the building might also be necessary depending on the situation, the immediate action should focus on the well-being of the individuals experiencing distress. Once they are safely out of the area, further steps can be taken to assess and address the source of the issue.
