Which sector is used to control access to a building during emergency situations?

The sector typically used to control access to a building during emergency situations is the lobby. In emergencies, the lobby often serves as the primary entry point for emergency responders and can be a crucial area for managing access and ensuring that non-responders do not enter hazardous environments.

In many cases, the lobby allows for the coordination of activities, such as directing personnel, managing crowd control, and providing information to both emergency services and building occupants. It helps establish a controlled environment where the flow of people can be monitored effectively, especially when safety and security are paramount.

While security personnel may also play a role in controlling access, especially in terms of identifying individuals or maintaining order, the lobby acts as a physical space where these efforts can be centralized. It becomes a critical location for incident command and communication, making it essential during emergencies.
