In 1992, Factory Mutual Research Corporation (FMRC) and the National Research Council Canada (NRCC) initiated a joint research project on upward flame spread in which NRCC set-up and conducted upward flame spread tests using a large-scale radiant panel facility. The test procedure, developed as part of the joint research project, is described and the results obtained using plywood specimens are discussed. The University of Kentucky team was invited to join this project and to provide their expertise on automated infrared temperature measurements. The identical materials were also tested using a bench-scale fire test apparatus to provide input for the FMRC upward Flame Spread and Growth (FSG) model. An overview of the FSG model and the small-scale tests is provided in this paper. Simulations for both the small-scale and full-scale tests with plywood specimens are provided and comparisons made with the experimental results.

Fire detection systems play a crucial role in ensuring safe evacuation and firefighting operations in road tunnels, but information on the performance of these systems in tunnels has been limited and guidelines for their application in tunnel environments are not fully developed. Recently, the National Research Council of Canada (NRC) and the Fire Protection Research Foundation completed a 2-year international research project, with the support of private-and public-sector organizations, to determine some of the strengths and weaknesses of the various types of fire detection systems and the factors that can affect their performance in tunnel environments. The project included both laboratory and field fire tests combined with computer modeling studies. Although this research was conducted on road tunnels, the findings should apply to other tunnels, such as those used in subway systems. As part of the project, the NRC conducted two series of tests in the Carleton University-NRC tunnel facility to investigate the performance of detection systems under minimal and longitudinal airflow conditions. In addition, NRC conducted tests in the Carre´-Viger Tunnel in Montre´al, as well as a computer modeling study. The project studied nine fire detection systems that covered five types of currently available technologies. The performance of the detection systems, including response times and ability to locate and monitor a fire in the tunnel and the effect of the tunnel environment, were evaluated under the same conditions. This article provides an overview of the findings of the project. Fire detectors, fire scenarios and test protocols used in the test program are described. A summary of the research results of the full-scale fire tests conducted in a laboratory tunnel facility and in an operating road tunnel as well as of the computer modeling activities is reported.

Properly engineered CAF systems produce superior quality foam with high momentum. However, until now, there has not been a study to systematically evaluate the fire suppression effectiveness of mobile CAF systems.NRC has carried out a project to evaluate the effectiveness of a mobile CAF system in suppressing fully developed compartment fires. Several full-scale compartment fire tests were conducted to compare the fire suppression performance of a manually-applied CAF system with that of hose stream application using water alone and using water-foam solution, under similar conditions.The study showed that a CAF system is much more effective in suppressing the compartment fire compared to hose stream application with water only or with foamwater solution. A CAF system with a 95 L/min (25 GPM) water flow rate suppressed the test fire bett...
