近年来,许多国家已经开始对人在火灾中的行为进行研究。这些研究包括人们在火灾情况下对火灾警报的反应,灭火器的使用,烟雾中的运动,以及疏散路线的使用等的假设。由于火的本性这几年有了某些程度的变化,特别是从高分子材料中所放出的毒烟给火灾时建筑物中居住者如何快速而安全地撤离增加了新的难题。因此,为了人们的生命安仝,进行科学调查,制订更合适的措施,已迫在眉睫。 我们知道,按照建筑规范、标准和规定进行建筑设 In recent years, many countries have begun to study people’s behavior in the fire. These studies include the assumption that people respond to fire alarms in case of fire, the use of fire extinguishers, the movement in smoke, and the use of evacuation routes. Due to some changes in the nature of the fire over the years, particularly the toxic smoke emitted from polymer materials has added new challenges to the occupants of buildings in the event of a fire evacuating quickly and safely. Therefore, in order to ensure people’s lives in peace, conduct scientific investigations and formulate more suitable measures, it is imminent. We know that building is in accordance with building codes, standards and regulations
