In response to a request from the Providence Ambulatory Health Care Foundation (SIC-8011), Providence, Rhode Island, the ventilation system at the Allen Berry Health Care Center was evaluated for suitability for preventing tuberculosis transmission. The system was operated in the automatic mode which meant that, if the temperature setpoints were met, no additional supply air entered the system to the examination rooms and the laboratory. Standing water was found in two of the units. Microbial growth was observed in the condensate pans under the air conditioning coils. Poor maintenance of the low efficiency fiberglass particulate filters was noted. One of the thermostats controlling the units was functioning improperly. Although the clinic had a tuberculin screening program for clients, there was no screening program for employees. The author concludes that there were deficiencies in the ventilation system which could potentially increase the risk of tuberculosis transmission. The author recommends that these deficiencies be corrected, and the tuberculosis control program in place at the clinic be strengthened.
