电工在检修低压电器装置时，容易发生的工伤事故有两类，即触电事故和高空摔跌事故。其中高空摔跌事故往往也是由触电所引起，并会造成重伤或死亡。
在一般情况下，电工停电进行检修操作，不准带电操作。但是，由于种种原因，在检修点往往会突然来电。如断开的电源总开关被人误合闸、没有明显断开点的断路器(如自动开关和接触器)受强烈震动而发生弹跳性误合闸等。如果在检修点出现意外带电，电工就很可能发生触电事故。因此，电工在日常检查和维修工作时，必须严格执行停电检修的安全工作规程，防止造成触电事故。
1 可能造成的触电回路
电工在检修时可能造成的触电回路，通常有以下三种：
(1) 两线间的触电回路：当检修者人体的两个不同部位同时触及两根导线的裸露部分，或两个接线端子时，人体就接通了两线间的电路，形成触电回路，如果触及的是低压线路的两根相线，则人体承受的是380V的线电压；如果人体触及的是一根相线和一根中性线，则人体承受的是220V的相电压。
