电器火灾 家用电器导致火灾主要有4种情况:①使用电热器具不慎易发生火灾。像电炉、电熨斗等电力加热器具,由于长时间使用,使高温烤着可燃物而失火。其预防措施是,在使用时,把它放置在耐火而绝热的基座上,附近隔离易燃物品,使用完毕或人离开时要关掉电源。②线路老化、接触不良易发生火灾。灯座、开关、插座长时间使用后触点表面氧化发黑积炭,接触不良产生火花引燃周围的易燃、可燃物。为避免此类事件发生,要经常检查电器线路及开关插座,发现问题及时更换。③安装使用不当易引起火灾。在安装使用功率
Electrical fire appliances lead to fire there are four main situations: ① use of electric appliances accidentally prone to fire. Such as electric stove, iron and other electric heating appliances, due to prolonged use, so that high temperature roasted combustible and fire. The precautionary measure is that, in use, place it on a fire-resistant and heat-proof base with flammable objects nearby, and turn off the power when use is finished or when people leave. ② aging lines, poor contact prone to fire. Lampholders, switches, sockets after prolonged use of the contact surface oxidation black coke, sparks ignited poor contact around the combustible, combustible material. To avoid such incidents, we must always check the electrical wiring and switch socket, find the problem promptly replaced. ③ improper installation and easy to cause a fire. Used in the installation of power
