Abstract:
One of the primary risks to healthcare workers and the public is exposure to persons with unsuspected or undiagnosed infectious Tuberculosis (TB). Exposures of this type may occur in areas such as waiting rooms, corridors, or emergency
rooms in healthcare facilities (e.g., hospitals, correctional institutions, nursing homes, clinics). While mechanical ventilation systems may provide protection to workers in these situations, there are limitations such as environmental constraints, cost, and comfort considerations.
Research indicates that an appropriately designed and maintained upper-room UltraViolet Germicidal Irradiation (UVGI) system may kill or inactivate airborne TB bacteria and increase the protection afforded to healthcare workers while maintaining a safe level of UVGI in the occupied lower portion of the room. The purpose of this document is to examine the different parameters necessary for an effective upper-room UVGI system and to provide guidelines to healthcare managers, facility designers, engineers, and industrial hygienists on the parameters necessary to install and maintain an effective upper-room UVGI system. It provides an overview of the current knowledge concerning upper-room UVGI systems and research needs.
