Title Germicidal ultraviolet irradiation in air conditioning systems: Effect on office worker health and well-being - A pilot study
Bibliographic information June 1999, Vol.56, No.6, p.397-402. 34 ref.
Abstract The objectives of this study were to test whether installation and operation of gernimicidal ultraviolet (GUV) lights in central ventilation systems would be feasible, without adverse effects, undetected by building occupants, and effective in eliminating microbial contamination. 104 workers participated; their environmental satisfaction ratings were not different whether GUV lights were on or off. Headache, difficulty concentrating and eye irritation occurred less often with GUV lights on whereas skin rash or irritation was more common. Overall, the average number of work-related symptoms reported was 1.1 with GUV lights off compared with 0.9 with GUV lights on. Installation and operation of GUV lights in central heating, ventilation and air conditioning systems of office buildings is feasible, cannot be detected by workers, and does not seem to result in any adverse effects.
