How is the location cleaned after a positive case is identified?

When a positive case is confirmed, within four to eight hours, SMU custodial workers deep clean and sanitize the area in which the person worked or lived, as well as adjacent rooms and public spaces in the building.

In addition to routine enhanced frequent high-touch cleaning protocol, a broad disinfection of the identified and unoccupied areas will take place via electrostatic spraying. All known touch points will be disinfected in the generally used public spaces such as all entrances, elevators, stairwells, door handles, restrooms, hallways, related break areas, conference rooms and common areas. The zone-disinfecting spraying will follow all paths of entry and exit points for the specific space.

The entire three-step process is outlined in this handbook.
