NIOSH 1994 Feb:16 pages
In response to a request from the Providence Ambulatory Health Care Foundation, an investigation was begun into possible hazardous working conditions at the Capital Hill Health Care Center (SIC- 8011), Providence, Rhode Island. Specific concern was expressed about the suitability of current ventilation systems for preventing tuberculosis (TB) transmission at the facility and four other health care centers. This clinic was served by four single zone, heating, ventilating, and air conditioning (HVAC) package units located on the roof, as well as an additional air conditioning unit for the perimeter offices, laboratory and conference room. The heating, ventilating and air conditioning units were operated in an automatic mode. This resulted in no supply air being delivered to the examination rooms or the laboratory when temperature setpoints were satisfied. The author concludes that deficiencies in the ventilation system potentially increased the risk of TB transmission and contributed to other indoor air quality problems. The author recommends that changes be made to the HVAC system to provide airflow at all times. An isolation room for the TB clinic, a formal employee tuberculin skin test, and a policy for health care workers regarding the use of respiratory protection should be established.
