EVERGREEN POINT BRIDGE TOLL BOOTH VENTILATION STUDY

A COMPREHENSIVE STUDY WAS CONDUCTED OF THE EXPOSURES OF TOLL COLLECTORS TO CARBON MONOXIDE AT THE EVERGREEN POINT BRIDGE SPANNING LAKE WASHINGTON BETWEEN SEATTLE AND BELLEVUE. AN AUTOMATIC, CONTINUOUS CARBON MONOXIDE MONITORING SYSTEM WAS DESIGNED AND USED TO ESTABLISH TYPICAL AIR QUALITY PATTERNS IN AND AROUND THE TOLL BOOTHS. A PROTOTYPE TOLL BOOTH POSITIVE VENTILATION SYSTEM WAS DEVELOPED. AIR, WHICH IS INTRODUCED THROUGH A VERTICAL DIFFUSER SITUATED AT ONE WALL OF THE BOOTH, TRAVELS HORIZONTALLY ACROSS THE BOOTH AND OUT THE DOOR. CONCENTRATIONS OF CARBON MONOXIDE IN THE COLLECTORS BREATHING ZONE WAS REDUCED TO ACCEPTABLE LEVELS. METHODOLOGIES AND RESULTS OF THE STUDIES ARE DESCRIBED, AND DESIGN RECOMMENDATIONS FOR THE CONTROL SYSTEM ARE OFFERED. /AUTHOR/
