造成触电事故的因素是:电流流过人体。

发生触电事故的主要原因有以下几种:

1、缺乏电气安全知识,在高压线附近放风筝,爬上高压线杆画个窝;低压架空线路断后,用手捡起火线;夜间带电布线手触带电体;用手触摸损坏的橡胶盖。

2、违反操作规程,未采取必要的安全措施,擅自用电的;触摸损坏的设备或电线;Mis-mounted现场设备;电气照明器材;电动工具的现场维修;带电移动电气设备;用湿手拧电灯泡等。

3、设备不合格,安全距离不够;二线接地系统接地电阻过大;地线不合格或断开;绝缘损坏、电线外露等。

预防触电事故

1、非电工不得拆卸或修理电气设备。如发现有损坏的电线、开关、灯头、插座,请及时联系电工维修。

2、不得使用维修中的电气设备。不得使用绝缘损坏的电气设备。

保险丝烧断,容量不允许更换保险丝。

4、电气设备的外壳应接地或接地保护。应经常检查对地或对零设备,确保连接牢固;应该没有接地或空线的断开。

5、如果发生电气火灾,应立即切断电源,用干粉灭火器、二氧化碳灭火器灭火。不要使用水或泡沫灭火器,因为它们具有危险的导电性。

如何预防触电事故

1、损害的开关、插座、电线等应赶快修理或更换,不能将就使用。        

2、不懂电气技术和一知半解的人,对电气设备不要乱拆、乱装,更不要乱接电线。        

3、灯头用的软线不要东拉西扯,灯头距地不要太低,扯灯照明时,不要往铁线上搭。     

4、电灯开关最好用拉线开关,尤其是土地潮湿的房间里,不要用床头开关和灯头开关。 

5、屋内电线太乱或发生问题时,不能私自摆弄,一定要找电工来改修。       

6、拉铁丝搭东西时,千万不要碰附近的电线。        

7、屋外电线和进户线要架设牢固,以免被风吹断,发生危险。       

8、外线拆断时,不要靠近或用手去拿,应找人看守,赶快通知电工来改修。        

9、不要用湿手、湿脚动用电气设备,也不要碰开关插销,以免触电。        

10、大清扫时,不要用湿抹布擦电线、开关和插座,也不要用水冲洗电线及各种用电器具、电灯和收音机等。        

11、架设收音机、电视机和矿石收音机的天线,不要靠近电力线,以免线被风吹断,掉在电力线上面而发生危险。        

12、当灯头的螺丝口露在灯口外面时,应安装灯伞成保护圈,或换用能把螺丝口包上的长灯头,以免开闭灯时触电。        

13、应该经常教育子女,不要玩弄开关、插座、收音机和其它各种电器等,以免发生危险。       

14、晒衣服或搭手巾时不要搭在电线上。
