The document describes Litum's electronic badge system for conducting emergency evacuations. The system works as follows:
1) Each employee is given an electronic badge that transmits a unique signal for identification.
2) During an evacuation, safety personnel scan the badge signals from multiple assembly points using a mobile app to get an instant headcount.
3) The scanned IDs are compared to the current employee roster downloaded periodically from the time & attendance system to identify any missing persons still inside the building.
