Assessment of Emergency Room Designs for Protection against an Internal Chemical Threat

摘要: Emergency rooms are critical infrastructures that provide acute care and rapid treatment of sudden illnesses trauma. These life saving services must remain in continuous operation. An internal chemical attack on an emergency room would interrupt these essential severely impact the capabilities health professionals staff. In this paper, a combination multizone simulation statistical modeling used as tools to assess designs for protection against threat. Design options include: use dilution ventilation, additional air handling equipment, gas phase filtration, building segmentation, sensor system improve response time. Protection levels placed into discrete categories ordered probability model (with random effects) is estimated. This identifies factors, such design option, type, elapsed time after release, unit's operational maintenance costs significantly influence levels. Marginal effects also computed measure factors protection-category probabilities. The results study can assist owners, designers, decision makers by providing quantitative methodology threats.
