In 2007, UL partnered with the Chicago Fire Department and the University of Cincinnati College of Medicine to further investigate the causal relationship between sub-micron smoke particles and the risk of cardiovascular problems. During the study, data was collected on the smoke and gas effluents to which firefighters are exposed during routine firefighting operations, as well as contact exposure from contaminated personal protective equipment. This research was funded by a grant from the U.S. Department of Homeland Security (DHS). The project included investigations on three fire scales: (1) fires in the Chicago metropolitan area, (2) residential room content and automobile fires, and (3) material-level fire tests. Detected effluent gases, airborne chemicals and smoke particulates were assessed by the University of Cincinnati College of Medicine for their potential adverse health effects on fire service personnel.
In the material-level fire test portion of the study, the combustibility, smoke and gas characteristics of 42 different residential construction and furnishing materials were characterized using the methodology developed in the UL-FPRF Smoke Characterization Project. This increased the number of measured smoke signatures from the 18 materials (originally completed in the UL-FPRF Smoke Characterization Project) to the 60 smoke signatures now currently identified. The Firefighter Exposure to Smoke Project study produced the following key findings:
