5/1/2011 - Peer reviewed journal articlesThis paper discusses the impact of ventilation airflow on alarm times of the smoke detectors and video cameras, CO levels, smoke optical densities and smoke obscuration, total smoke mass concentrations, and fire heat release rates.
-
2/1/2009 - Conference papersThis report describes experiments and their results in determining the responses of a prototype smoke detector and a commercially available photoelectric smoke detector to smoke particles generated from various combustion sources.
-
9/1/2007 - Conference papersThis paper reviews how simultaneous application of three basic elements reduces the methane explosion hazard at coal mine working faces: (1) adequate ventilation, (2) regular monitoring of gas concentrations, and (3) elimination of ignition sources.
-
1/1/1991 - Reports of InvestigationsThis report details the results of a series of large-scale experiments where small coal fires were used to ignite the conveyor belt at specific air velocities, and showed conditions required for early detection of conveyor belt entry fires.
-
