The Safe web application helps employees return safely to the workplace. Safe provides companies with an automated contact history for employees who self-report testing positive for COVID-19. By running a contact history, customer administrators can prevent further disease spread by requesting that exposed contacts voluntarily self-quarantine while maintaining the operations of the facilities with employees that were not at risk of coming in contact with employees that tested positive.
The solution utilizes Enlighted’s Bluetooth Low Energy employee badges in combination with the Enlighted sensor network.
The solution prioritizes privacy by eliminating the need for storing personal information. Employees are assigned alphanumeric ID badges while entering the workplace. When an employee self-reports their badge ID and a positive test result, administrators query the Safe application, identify other badges this employee came in contact with, and share the anonymous IDs. Employees carrying those badge IDs can self-identify their exposure without revealing any names.
Alternatively, employers may choose to map badge IDs to employee names on their internal systems.
Contact tracing begins when an occupant self-reports to the customer administrator that they tested positive for the virus—the customer admin logs into the Safe web application using their company’s credentials. Suppose an occupant with Badge ID-100432 tested positive for the virus; the occupant reports their Badge ID to the admin.
The admin searches for all other badges that were in contact with the Badge ID-100432,
- Type or select the Badge ID of the infected person from the dropdown list.
- Select the proximity. Proximity is identified as Close, Near, and Far. Proximity definitions can be custom-defined. See Configure Settings. By default:
- Close – A close contact is a badge that was about 2 meters or less from the badge being queried.
- Near – A near contact is a badge that was about 3 meters or less from the badge being queried.
- Far – A far contact is a badge that was about 4 meters or less from the badge being queried.
- Select the duration. Duration is the amount of time spent with the infected person at a distance less than the selected proximity. The customer may choose five duration options. The default query options are 1, 2, 5, 15, and 30 minutes.
- Select a Start and End Date from the pop-up calendar. By default, customers can query date ranges for the last 30 days.
- Click Search.
The search reports every Badge ID that the queried badge came in contact with for the specified proximity and duration along with the number of events. The events represent the number of times (i.e., contact events) that the badge came in contact with the queried badge.
For example, in the screen below, Badge ID-100432 was near two other people for greater than five minutes, one person for a total of about 11 minutes, and the other person for about five hours and 37 minutes.
By clicking the down arrow at the right end of the row for the badge with ID-672703, you can view the number of times the queried badge came in contact with Badge ID-672703 for the total duration of five hours and the number of times they came within the proximity.
The color of the icons indicates relative duration and proximity. Generally, the red color indicates longer durations and, or closer proximities. Yellow color indicates shorter durations and, or farther proximities, that still lie within the search criteria. These colors are relative.
You can also download the information into a CSV file by clicking the CSV download button on the top to either archive or integrate this information with other business processes.
