    Summary of Tracing systems in Emergency Exposure Management

    Tracing systems in Emergency Exposure Management enable ServiceNow customers to identify potentially exposed employees by analyzing various contact tracing data sources. By running diagnostic requests on affected employees, these systems help find individuals who may have interacted with them, thereby supporting effective exposure management. Multiple tracing systems can be selected simultaneously to broaden data coverage and enhance detection accuracy.

    Tracing systems can be organized hierarchically, grouping similar data sources under a parent tracing system for streamlined management and analysis. Customers can customize existing tracing systems or set up new ones based on available data sources. Some tracing systems require installation of additional Safe Workplace suite or Emergency Response Operations applications to be active.

    Key Features

    • Default Tracing Systems with Emergency Exposure Management: Active by default and include:
      • Location: Identifies employees co-located with the affected employee (e.g., same floor or building).
      • Outlook meetings: Identifies employees attending the same meetings as the affected employee via Microsoft Office 365.
    • Workplace Core Tracing System (requires activation and configuration):
      • Workplace reservations: Identifies employees with overlapping workplace shift reservations.
    • Contact Tracing Systems (require activation and data source setup): Include multiple data-driven tracing systems querying specific tables:
      • Badge reader: Employees who swiped the same badge readers as the affected employee.
      • Employee daily log: Employees recorded as having interacted with the affected employee.
      • Visitor log: Visitors invited by and interacting with the affected employee (requires Employee Health Screening installation).
      • Wi-Fi access log: Employees sharing Wi-Fi access points; includes child systems for Mist Systems and Cisco DNA Spaces integrations.
      • Handheld/Wearables: Employees with wearable devices in close proximity, including Zebra MotionWorks Proximity as a child system.
      • Kinexon SafeZone: Integration-based tracing for employees wearing KINEXON devices.
    • Field Service Management Tracing System (requires activation and configuration):
      • Field service: Identifies customers and field agents who interacted with or were visited by the affected field agent.

    Practical Considerations

    • Activation and configuration of certain tracing systems depend on the installation of related applications such as Workplace Core, Contact Tracing, Employee Health Screening, or Field Service Management.
    • Data retention policies of external providers, such as Wi-Fi service providers, affect the availability of real-time data through APIs.
    • Parent-child tracing system structures allow grouping of similar data sources, facilitating comprehensive exposure analysis.

    Key Outcomes

    ServiceNow customers leveraging these tracing systems can:

    • Accurately identify potentially exposed employees using diverse and integrated data sources.
    • Broaden exposure detection by combining multiple tracing systems in diagnostic requests.
    • Customize or extend contact tracing capabilities tailored to their workplace environments and data availability.
    • Support timely and informed exposure response efforts to enhance workplace safety and compliance.

    A tracing system configured for a contact tracing data source enables you to identify potentially exposed employees by running a diagnostic request.

    The diagnostic request for an affected employee queries the contact tracing data to identify people who might have interacted with the affected employee. You can select multiple tracing systems in a diagnostic request to use multiple data sources to broaden the coverage used to find potential exposure.

    A tracing system can be a group of other tracing systems with a similar type of input data source. For example, say you have Wi-Fi access data integration with multiple systems such as Cisco DNA Spaces and Mist Systems. You could have a tracing system called Wi-Fi access log and make it the parent tracing system of other tracing systems using the Wi-Fi input data sources.

    You can customize the tracing systems for data sources available in Emergency Exposure Management or set up a new tracing system. For more information, see Set up a tracing system for an exposure data source.

    For some tracing systems to be available in Emergency Exposure Management, you must install other Safe Workplace suite and Emergency Response Operations applications.

    Tracing systems installed with Emergency Exposure Management

    These tracing systems are active by default.
    Table 1. Emergency Exposure Management tracing systems
    Tracing system Query
    Location Employees co-located with the affected employee, for example, on the same floor or building.
    Outlook meetings

    Microsoft Office 365

    		 Employees who accepted the same meetings as the affected employee during the specified time period.

    Tracing system installed with Workplace Core

    This tracing system is not active by default. To use this tracing system for identifying potentially exposed employees, activate it and also configure the corresponding data source in Workplace Core.

    For more information, see Install Workplace Safety Management.

    Workplace reservations Employees who had reservations for the same shifts as the affected employee during the specified time period.

    Tracing systems installed with Contact Tracing

    These tracing systems are not active by default. To use these tracing systems for identifying potentially exposed employees, activate them and also configure the corresponding data sources in Contact Tracing.

    For more information, see Setting up Contact Tracing.
    Table 3. Contact Tracing tracing systems
    Tracing system Query
    Badge reader Queries the Badge Access Register [sn_imt_tracing_badge_access_register] table to fetch employees who swiped their badge on the same badge reader devices as the affected employee during the specified time period.
    Employee daily log Queries the Daily Contact Logs [sn_imt_tracing_daily_contact_log] table to fetch employees with whom the affected employee interacted during the specified time period.
    Visitor log Queries the Visitor Request For Entry [sn_imt_monitoring_visitor_request_for_entry] table to fetch visitors who interacted with the affected employee during the specified time period. Visitors who visited the workplace on invitation from the affected employee and have been screened through and let in are queried.

    Ensure that you have installed Employee Health Screening to use this tracing system.
    Wi-Fi access log Queries the Wi-Fi Access Register [sn_imt_tracing_wifi_access_register] table to fetch employees who used the same Wi-Fi access points as the affected employee during the specified dates.
    Wi-Fi access log data used to identify potentially impacted employees depends on Wi-Fi location preferences and available integrations. The tracing system has the following child tracing systems based on the data source:
    • Mist Systems
    • Cisco DNA Spaces

    For more information, see Retrieving Wi-Fi access log data.

    Note:
    The period for which you can get the data via a real-time API depends on the data retention policy of your Wi-Fi service provider.
    Handheld/Wearables Queries the Wearable Access Register [sn_imt_tracing_wearable_access_register] table to fetch employees equipped with handheld or wearable devices who were in the close proximity with the affected employee during the specified time period.

    The Handheld/Wearables tracing system has the Zebra MotionWorks Proximity tracing system added as a child tracing system.
    Kinexon SafeZone Uses an integration with the KINEXON SafeZone API to identify potentially exposed users with KINEXON wearable devices who were in close proximity with the affected KINEXON user during the specified dates.

    For more information, see Configure KINEXON integration.

    Tracing system installed with Field Service Management

    This tracing system is not active by default. To use this tracing system for identifying potentially exposed employees, activate it and also configure the corresponding data source in Field Service Management.

    For more information, see Emergency Exposure Management for field service agents.
