電(dian)氣設備(bei)是(shi)(shi)起(qi)重(zhong)(zhong)機的重(zhong)(zhong)要(yao)(yao)組成部分，用(yong)電(dian)裝置是(shi)(shi)動力裝置，正確掌握用(yong)電(dian)的安全(quan)知識，防止電(dian)氣傷害事(shi)故發生是(shi)(shi)非(fei)常重(zhong)(zhong)要(yao)(yao)的。如何防止電(dian)氣設備(bei)發生意(yi)外(wai)事(shi)故？
保(bao)護(hu)(hu)接(jie)地和保(bao)護(hu)(hu)接(jie)零都是防止電(dian)(dian)(dian)子設(she)備意外帶(dai)電(dian)(dian)(dian)，造成觸電(dian)(dian)(dian)事故的(de)安(an)全技術(shu)措施。接(jie)地是人們都知道的(de)用電(dian)(dian)(dian)常識，如果電(dian)(dian)(dian)氣設(she)備的(de)絕緣損壞而使金屬外殼(ke)帶(dai)電(dian)(dian)(dian)時，人們就算碰到(dao)也不會有多(duo)大的(de)傷害，保(bao)護(hu)(hu)了人們的(de)安(an)全。用電(dian)(dian)(dian)安(an)全是非常重(zhong)要的(de)。這是基本(ben)的(de)用電(dian)(dian)(dian)安(an)全常識，除此以(yi)(yi)外，平時要注意對(dui)電(dian)(dian)(dian)氣設(she)備的(de)檢查，正確操作(zuo)，可以(yi)(yi)在碼(ma)頭起重(zhong)機上(shang)面安(an)裝防護(hu)(hu)裝置，一旦發生什么(me)問題可以(yi)(yi)立即(ji)斷電(dian)(dian)(dian)，減少危(wei)害。
