Fixed Fire Fighting and Emergency Ventilation Systems for Highway Tunnels – Workshop Report

There is a lot of global experience with fixed fire fighting systems in road tunnels, particularly in Australia and Japan, but also in several recently constructed tunnels in the United States and Europe. The U.S. first implemented FFFS in their tunnels in the 1950s, however, this approach did not become routine, partly due to unsuccessful tests of FFFS in the Offneg Tunnel in Europe. Because FFFS were not routinely applied in all tunnels, the present-day approach can vary between planned facilities and regions, especially in critical design areas such as operational integration with the emergency ventilation system (EVS). Further research and a design-focused approach to computational modeling and testing is needed to develop a set of suggested practices for the operational integration of FFFS and the EVS. This document describes the industry workshop, held in Washington, DC on January 15 and January 16, 2020. Workplans for computer modeling and testing (laboratory and full-scale) are also described.
