1. Introduction
Fire safety is an integral part of fire precautions. Fire precautions have the objective to minimize the number of and damage from fires by measures hindering their initiation, limiting their propagation and if possible excluding flashover. Preventing fires or delaying them makes escape possible over a longer period of time. As a result, life, health and property are efficiently protected.
Basically, the course of a fire is always the same: it consists of the phases initiating, fully developed and decreasing fire. Fire precautions for combustible materials only apply to the early stage of a fire, i.e. the initiating fire phase by preventing ignition and by influencing the parameters fire propagation and heat release.
2. Fire statistics
Modern ®re precautions guarantee a high level of fire safety and virtually exclude catastrophic fires which, only one century ago, razed entire towns. However, even today, fire statistics show a high death toll

1. 介绍 防火安全是火灾防备措施的整体部分。火灾防备措施有宗旨使数字和损伤减到最小从火由措施妨害他们的启蒙, 限制他们的传播和如果可能除了飞弧。预防火灾或延迟他们牌子逃脱可能在一个更长的时期。结果, 生活、健康和物产高效率地被保护。 基本上, 火的路线总是相同: 它包括阶段创始的,充分地被开发的和越来越少的火。火灾防备措施为可燃烧的材料只适用于火, 即创始的火阶段的早期由防止燃烧和由影响参量火传播和热发行。
2. 火统计 现代.re 防备措施保证一个高水平防火安全和实际上排除灾难火哪些, 只有一个世纪前, 被忘却的整个镇。但是, 甚而今天, 火统计显示高的死亡人数和巨大的损失为经济。根据Wilmot [ 1 ], 在美国, 1991 年有4860 火死亡(1989 年: 5880 死亡) 。损失由火造成超出亿万(直接损失美国1989 年: 9.2 亿万; 1991 年: 10 亿万USD) 。 新立法的影响是根本的为增加防火安全水平在许多领域。1988 年一个醒目的例子是英国章程的介绍为火焰被减速的被布置的家具: 它显示火和死亡剧烈的下落从被布置的家具(比较1988 年-- 1993 年: 4818 -- 3746 火; 247 -- 146 火死亡)
