Evaluation on Egress Safety of Nursing Hospital Considering the Smoke Exhaust System

This study aimed to evaluate the egress safety in nursing hospitals based on capacity of smoke exhaust system. To this end, available safe time was calculated by analyzing changes visibility, carbon monoxide, dioxide, oxygen contents, and temperature depending fire duration. In addition, an simulation performed using number workers (egress guides) delay as variables, required estimated. Based results, a prototype hospital evaluated. study, criteria typical were presented, which are expressed terms normalized guides, ratio system, time. The proposed can be used prepare complementary measures.
