A reasonable assumption would be that any announcement you hear on the high-rise building's PA system is not being made by a person who has knowledge of the situation, but was recorded years or months earlier in a studio and is being automatically played by a control system based on sensor data. The sensor data may or may not be good, and the control system may or may not have been programmed correctly.
A second reasonable assumption would be that any employee of the building management company has, as his or her objectives, in declining order of priority:
- Don't disrupt operations
- Don't create bad PR
- Don't disturb the tenants
- Keep people safe
