Ultraviolet germicidal irradiation of office ventilation systems reduces work-related mucosal and respiratory symptoms
Question
What is the effect of ultraviolet germicidal irradiation (UVGI) in office ventilation systems on worker's health and wellbeing?
Study design
Double blind multiple crossover trial.
Main results
Ultraviolet germicidal irradiation (UVGI) lights significantly reduced the incidence of overall work-related symptoms (14% of symptoms only reported when UVGI on vs. 18% symptoms only reported only when UVGI off; OR 0.8, 95% CI 0.7 to 0.99). UVGI significantly reduced work-related mucosal and respiratory symptoms but not systemic or musculoskeletal symptoms (OR for mucosal symptoms 0.7, 95% CI 0.6 to 0.9; OR for respiratory symptoms 0.6, 95% CI 0.4 to 0.9; OR for systemic symptoms 1.1, 95% CI 0.9 to 1.3; OR for musculoskeletal symptoms 0.8, 95% CI 0.6 to 1.1). UVGI reduced microbial and endotoxin concentrations on irradiated surfaces within ventilation systems by 99% (95% CI 67% to 100%).
Authors’ conclusions
UVGI may be a cost-effective method of alleviating work-related symptoms caused by microbial contamination of office ventilation systems.
