In response to a request from the Senior Industrial Hygienist, Department of Community Health and Medical Care, St. Louis County, an investigation was made of occupational exposure to ultraviolet radiation emitted by germicidal lamps at the Tuberculosis Clinic of the John C. Murphy Family Health Center (SIC-8099), Berkeley, Missouri. Measurements were taken on all lamps at the tuberculosis (TB) clinic. There were approximately 140 staff at the site and they provided care to about 200 to 400 patients per day, 5 days/week. The results of the evaluation indicated that levels of occupational exposure to radiation from germicidal lamps in most of the work areas were below the NIOSH Recommended Exposure Limit of were in the levels at very close distances to the lamps. Other findings noted were the presence of older lamps, inappropriate labeling and posting of signs, and ventilation deficiencies in the TB clinic area. The authors conclude that a health hazard could exist from exposure to the lamps at a distance of 10.2 centimeters, if the staff were not wearing protective eyewear. The authors recommend minimizing the ultraviolet exposures as well as improving certain ventilation parameters.
