Safety measures

The purpose of this study was to explore and describe the pre-disaster planning processes and practices used by Florida's community college administrators as of December 2008. FEMA's Building a Disaster Resistant University (DRU) model was the conceptual lens for this study. A mixed methods research design included 15 surveys completed by Florida community college business officers and six semi-structured interviews with staff most involved in pre-disaster planning. Data were compared to DRU guidelines to establish whether processes and practices were congruent with the DRU. Six quantitative findings were reported in this study. First, 5 of 14 (35.7%) survey respondents appointed a project manager ; second, 14 of 15 respondents (93.3%) conducted a risk assessment ; third, 13 of 15 (87%) respondents reported contacting 2 to14 stakeholders; fourth, 14 of 15 (93.3%) survey respondents conducted an inventory of buildings and infrastructure assets; fifth, majority of survey respondents ( 87.7%) reported they identified mitigation goals and objectives; sixth, 8 of 14 (57.1%) respondents' president formally adopted the pre-disaster mitigation plan.

The combination of highly turbulent airflow, flammable fluids, and numerous ignition sources makes aircraft engine nacelles a difficult fire zone to protect. Better understanding of nacelle air flow and how it influences the spread of fires and fire extinguishing agents is needed to improve the efficiency of fire suppression. The first objective was to establish a CFD model for a flow field test section to analyze the transport and dispersion of fire extinguishing agents in the presence of various clutter elements. To validate the use of the CFD model, the simulation results of the CFD model were compared to the experimental data and they show an agreement with the experimental data. The second objective was to present parametric studies to show the effects of the coflow speed, turbulence intensity and agent droplet size on the transport and dispersion of the agent particles downstream from the clutter elements.
