A study was made to document and evaluate effective technologies for the control of potential health hazards at Community North Hospital (SIC-8062), Indianapolis, Indiana. The study evaluated effective ways of maintaining negative pressure in isolation rooms used for infectious tuberculosis patients. Six isolation rooms were examined. Two rooms each had a two position switch which controlled the exhaust flow rate by positioning dampers in the exhaust duct. The switch cover plate labels for one room were incorrect, indicating a positive pressure condition when there was actually a negative pressure condition. All rooms exhausted directly to the outdoors. Each room provided at least 6 air changes per hour, and five of the six rooms had a minimum negative pressure of 0.001 inch of water.
