Summary:碩士 === 中華科技大學 === 土木防災與管理碩士班 === 103 === Nowadays, the aggravated slowdown of birth rate, caused by the pressure of economy competition and the change of value among new generations, has provoked another kind of national security. The aging phenomenon can threaten our society, and the reliable and safe Long-Term Health-Care Institutions should be crucial issue to our government. Taking the fatal fire alarm with 13 dead and 70 injured in Tainan nursing home Sin-Ying Hospital Bai-Men branch on 2012/10/23 as an example, we can find out that most patients were unable to escape away from the fire caused by impaired physical conditions as well as insufficient nurses to implement evacuation. Nowadays, although there’re overflowed caring centers and institutions, they are existed in metropolitan apartments without sufficient space and walking aisles, which can cause serious injury and/or death. This research is to focus on helping impaired elders escape away from the fire by adding more equipment for life security and extended rescue under present conditions. The research uses the Fire Dynamics Simulator by NIST/BFEL (National Institute of Standards and Technology Association Fire Laboratory) to simulate the fire alarm with the time that the smoke can be down to the ground to jeopardize refuge; then, specific steps to limit the smog within some area and/or space for fleeing or rescuing lives from fire should be adopted. The research indicates that additional smoke ventilation equipment can decelerate the speed of smoke down to the ground and improve visibility efficiently, which favors rescue and heat emission for restraining the acceleration of temperature and density of CO2 for safer environments before the arrival of fire fighters for patients. Furthermore, this research also strongly suggests to have the exhaust equipment at the main exit once if only with one-row exhaust equipment.
