火灾中的自我保护方法
1、正确使用“119”电话:报警时,首先要沉着冷静，不要心慌，一要讲清楚起火单位、地址、燃烧对象、火势情况,并将报警人的姓名、所在的电话号码告诉消防队,以便联系。报警后，本人或派人到通往火场的交通路口接应消防车;二要早报警,为消防灭火争取时间,减少损失。
2、灭火的基本原理是：根据燃烧的基本条件，一切灭火措施，都是为了破坏已经形成的燃烧条件，或终止燃烧的连锁反应而使火熄灭以及把火势控制在一定范围内，最大限度地减少火灾损失。
3、灭火的基本方法有：
冷却灭火法，就是将灭火剂直接喷洒在燃烧着的物体上，将可燃物质的温度降低到燃点以下，终止燃烧。如用水灭火。
隔离灭火法，就是将燃烧物体与附近的可燃物质隔离或疏散开，使燃烧停止。
窒息灭火法，就是阻止空气流入燃烧区，或用不燃物质冲淡空气，使燃烧物质断绝氧气的助燃而熄灭。如用泡沫灭油类火灾。
抑制灭火法，也称化学中断法，就是使灭火剂参与到燃烧反应历程中，使燃烧过程中产生的游离基消失，而形成稳定分子或低活性游离基，使燃烧反应停止。如干粉灭火剂灭气体火灾。

5、以下火灾不能用水扑救：
电器发生火灾时,首先要切断电源。在无法断电的情况下千万不能用水和泡沫扑救,因为水和泡沫都能导电。应选用二氧化碳、1211、干粉灭火器或者干沙土进行扑救，而且要与电器设备和电线保持2米以上的距离。
油锅起火时,千万不能用水浇。因为水遇到热油会形成“炸锅”,使油火到处飞溅。扑救方法是,迅速将切好的冷菜沿边倒入锅内，火就自动熄灭了。另一种方法是用锅盖或能遮住油锅的大块湿布遮盖到起火的油锅上,使燃烧的油火接触不到空气缺氧窒息。
燃料油、油漆家中贮存的燃料油或油漆起火千万不能用水浇,应用泡沫、干粉或1211灭火器具或沙土进行扑救。
计算机电脑着火应马上拔下电源，使用干粉或二氧化碳灭火器扑救。如果发现及时,也可以拔下电源后迅速用湿地毯或棉被等覆盖电脑,切勿向失火电脑泼水。因为温度突然下降，也会使电脑发生爆炸。
化学危险物品在学校实验室常存有一定量的硫酸、硝酸、盐酸、碱金属钾、钠、锂,易燃金属铝粉、镁粉等。这些物品遇水后极易发生反应或燃烧,是绝不能用水扑救的。

6、发生火灾时不能乘一般电梯疏散：火场上不能轻易乘坐普通电梯疏散的原因：一是发生火灾后，往往容易断电而造成电梯“卡壳”,给救援工作带来难度,影响及时疏2023.10.2419:39To:4,commonlyusedfireextinguishersare:drypowderfireextinguisher,carbondioxidefireextinguisher,foamfireextinguisher.

7、火场逃生的自救方法：
a、发生火灾后,应尽快从安全通道、安全出口和消防楼梯撤离，切勿盲目乱窜或使用电梯逃生;
b、逃离火场时,遇到浓烟不要直立行走,应尽量采用低姿势行走或匍匐前行,用湿毛巾捂住口鼻,以免被浓烟窒息；
c、楼梯已起火，但尚未烧断且火势不很猛烈时，可披上用水浸湿的衣裤或被单由楼上迅速冲下。楼梯已经烧断且火势相当猛烈时，可利用绳子或把床单撕成条状连接起来，一端拴在牢固的门窗或其它重物上,然后顺绳子或布条滑下（三楼以上住户慎用）；
d、各种逃生之路均被切断时,应退回居室内,采取防烟堵火措施,关闭门窗,并向门窗上浇水,还要用湿毛巾捂住口鼻，做好个人防护，同时，向室外挥动鲜艳的东西(在夜晚则可向外打手电),发出求救信号；
e、一旦身上着了火,首先应当将衣服脱下,将火扑灭；或就地翻滚，窒息火苗。但不要滚动过快，更不要跑动。如果附近有水池、河塘等水源,可迅速跳入水中,或及时就近取水将身上火浇熄。但身体被烧伤时，应注意不要跳入污水中，以防感染。
