Development Of A Medium Scale Apparatus For Testing & Teaching Dispersed Dust Flame Effects, David Petrow

Online Theses and Dissertations

Combustible dust explosions and flash fires are a leading cause of property damage, injuries, and death in industries around the world. An example of a disastrous dust explosion occurred at CTA Acoustics in Corbin, KY in 2003. This explosion cost the lives of seven workers and injured 37 more. A mobile inexpensive dust dispersion apparatus (DDA) was designed, built, and tested to reproduce medium scale dust flash fires. By using fuel amounts varying from 0.45kg to 4.54kg the DDA created dust clouds ranging from 2.5m to 7.5m in diameter. With these measurements, the characterization of dust hazards and validation of …

Air Consumption And Air Management In The Fire Service, Otis Wesley Broderick

Online Theses and Dissertations

This research was undertaken in order to determine if there was a significant difference between various factors affecting air consumption rates and air management in the fire service. The purpose was to develop a better understanding of what had the most significant effect on air consumption rates in order to develop a point of focus so that fire departments could concentrate their efforts on an area of improvement that would give them the most return for their effort. An air management obstacle course was utilized to simulate work any firefighter could be reasonable expected to perform at a structure fire. …

Analysis Of Union Safety: Determining Relationships Between Union Membership And Injury And Fatality Rates, Madelyn K. Street

Online Theses and Dissertations

In under two centuries the labor union transformed the American workplace, improving wages, benefits, employee engagement, and safety. In more recent years, the government and other organizations have caught up in focusing on safety. Countless studies have been conducted and determined that unions have a significant positive impact on safety compared to work environments absent of a union. Using Bureau of Labor Statistics data for 2006-2015, an investigation into the trends of union membership and injuries and fatalities reported in the United States was conducted. It was determined that there was not significant correlation between increased union membership and improved …
