发生火灾时,如果发现火势并不大,尚未对人造成很大威胁,而周围有足够的消防器材,如灭火器、消火栓等,应奋力将小火控制、扑灭,千万不要惊慌失措地乱叫乱窜,置小火于不顾而酿成大灾。灭火的基本方法有三种:冷却灭火法、隔离灭火法和抑制灭火法。冷却灭火法能使可燃物质的温度降低到燃点以下而终止燃烧;隔离灭火法可将燃烧物体与附近的可燃物质隔离或疏散开,使燃烧停止;抑制灭火法可使灭火剂参与到燃烧反应过程中,使燃烧中产生的游离基消失,使燃烧
In the event of a fire, if it is found that the fire is not significant, it has not yet posed a great threat to the people, and there are enough fire-fighting equipment such as fire extinguishers and fire hydrants in the surrounding areas. Try to control small fires and put them out of control. Scurrying, home to ignore the fire caused by catastrophe. There are three basic ways to extinguish a fire: cooling fire extinguishing method, isolation fire extinguishing method and suppression fire extinguishing method. Cooling fire extinguishing method can make the temperature of combustible material below the ignition point to terminate the combustion; isolation fire extinguishing method can be separated from the nearby combustible materials or objects, to stop the combustion; suppression fire extinguishing method can make the fire extinguishing agent involved in the combustion reaction process In the combustion of free radicals disappeared, so that combustion
