Abstract
A study was made to document and evaluate effective technologies for the control of potential health hazards at Methodist Hospital (SIC- 8062) located in Indianapolis, Indiana. Ways were studied to maintain negative pressure in acid fast bacilli (AFB) isolation rooms, to quantify the parameters associated with negative pressure rooms, and to evaluate the effectiveness of those parameters. Four isolation areas were surveyed. Each was supplied conditioned air from a diffuser located above the door to the anteroom. Exhaust was provided at floor level near the bed through a grill. Electropneumatic switches sensed temperature and airflow direction into or out of the isolation room. The investigator noted three items of interest in this survey. Floor sweeps were used on the isolation to anteroom doors and anteroom to corridor doors. Two isolation rooms examined in the maternity unit were carpeted. Television sets in the rooms were located in wall recesses sealed from the room area behind plexiglass and equipped with dedicated exhaust for heat removal. All of the rooms had a minimum negative pressure of 0.001 inch of water, and the exhaust went directly to the outdoors.
