What occurs during a partial evacuation?

During a partial evacuation, some occupants are evacuated while others remain in the building. This type of evacuation is typically implemented when there is a specific area of concern, such as a fire or hazardous incident, but it does not necessitate evacuating the entire building. The goal is to ensure the safety of those in immediate danger while maintaining normal operations for those in unaffected areas. This approach helps to manage any potential confusion that may arise during a full evacuation and can be more efficient in situations where the threat is localized.

In contrast, a complete evacuation would involve all occupants leaving the premises, which is not the case here. Similarly, limiting the evacuation to only staff members does not align with the definition of a partial evacuation, as that would exclude certain occupants unnecessarily. Finally, preventing all occupants from exiting contradicts the nature of a partial evacuation, which involves the movement of some individuals to safety while others are instructed to stay put.
