Description

A significant portion of the Memorial Tunnel Fire Ventilation Test Program was devoted to determining the effectiveness of various extraction tests in limiting the spread of smoke and hot gases, with varying system configurations and air flow rates. The controlled fire, located at the approximate quarter point of the 2,800 ft (853 m) long tunnel, was varied at two levels of intensity: 20 and 50MW. A total of 17 single-point extraction and 5 oversized exhaust port tests were conducted, all in a single-zone partial transverse configuration. The single-point extraction tests utilised 100-, 200- and 300-ft2 (9.3-, 18.6-, and 27.9-m2) point openings both north and south of the fire. The oversized exhaust port tests applied fusible panels and fusible link dampers. Addresses results and conclusions drawn from these tests on the basis of acquired data.
