In response to a request from the Providence Ambulatory Health Care Foundation (SIC-8011), an investigation was begun into the ventilation system at the Central Health Care Center, Providence, Rhode Island, and the suitability of the system for minimizing tuberculosis transmission. The facility had 31 full time staff and up to 10 working part time as physicians, dentists and laboratory workers. The building was served by four single zone, heating ventilating, and air conditioning package units on the roof as well as an additional air conditioning unit for perimeter offices, laboratory, and conference room. The units were operated in an automatic mode which resulted in no supply air being delivered to the examination rooms and laboratory when the temperature set points on the system were reached. In some of the enclosed offices there were no supply diffusers to provide supply air. A tuberculin screening program was in place for clients but none for employees. The author concludes that the deficiencies noted in the ventilation system could increase the risk of tuberculosis transmission and cause other indoor environment problems. The author recommends specific measures to correct these deficiencies along with steps to strengthen the control program for preventing the spread of tuberculosis.
