    Summary of Tracing Systems in Emergency Exposure Management

    A tracing system in Emergency Exposure Management allows you to identify potentially exposed employees by querying contact tracing data. By utilizing diagnostic requests, you can find individuals who may have interacted with an affected employee. Multiple tracing systems can be selected to enhance exposure coverage.

    Key Features

    • Customizable Tracing Systems: You can set up new tracing systems or customize existing ones based on available data sources.
    • Active Tracing Systems: Certain tracing systems are active by default, including:
      • Employees Co-located: Identifies employees in proximity to the affected individual.
      • Outlook Meetings: Queries meeting attendees during a specified timeframe.
    • Workplace Core Integration: Requires activation and configuration to use the workplace reservations tracing system.
    • Contact Tracing Systems: Additional tracing systems require activation to fetch data from various logs, including badge access, daily contact logs, visitor logs, and Wi-Fi access logs.

    Key Outcomes

    By implementing these tracing systems, ServiceNow customers can effectively monitor and respond to potential exposure incidents, ensuring the safety of employees. Accurate tracing data enhances situational awareness and aids in timely decision-making regarding workplace health protocols.

    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.
    Table 2. Workplace Core tracing system
    Tracing system Query
    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.
    Table 4. Field Service Management tracing system
    Tracing system Query
    Field service Customers attended by an affected field agent during the specified time period. Also queries other field agents who interacted with the affected agent or visited the same customer as the affected agent during the specified time period.
