- Generally, UVGI is used to disinfect the air in the upper part of the room. Shielding devices are used to direct the light upwards away from eyes and skin.
- The use of these protection devices to deflect UVGI enables health personnel, patients and their visitors to remain in these areas for extended periods as the major concerns about UVGI have been adverse reactions, such as acute and chronic skin and eye changes from overexposure if the UVGI is not installed and maintained properly.
- Note that alone, UVGI does not provide outside air or circulate interior air, both of which are essential in achieving acceptable air quality in occupied spaces.
- When needed, UV lamps should always be cleaned with alcohol, not water. Protocols for maintenance should be followed.
