During a building evacuation, a security guard encounters an individual who refuses to leave, claiming they are not in danger. What is the most appropriate action for the guard?

1. Ignore the individual and continue with the evacuation of others, as you cannot force them to leave.
2. Stay with the individual and try to convince them until they agree to evacuate, delaying your other duties.
3. Physically escort the individual out, as their refusal poses a risk to others.
4. Clearly explain the urgency and importance of evacuation, and if they still refuse, report their location and description to emergency responders and incident command.
