電纜火災的撲救方法
電纜一旦著火，應采用(yong)下(xia)列方法撲滅：
（1）切斷起火電(dian)纜電(dian)源(yuan)。電(dian)纜著火燃(ran)燒，無論(lun)何原因引起，都應立即切斷電(dian)源(yuan)，然后(hou)，根據電(dian)纜所經過(guo)的路徑和特征，認真(zhen)檢查，找出電(dian)纜的故障(zhang)點(dian)，同時(shi)應迅速組(zu)織人員進(jin)行撲救。
（2）電(dian)(dian)(dian)纜(lan)(lan)溝內起火(huo)非故障電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的切斷。當電(dian)(dian)(dian)纜(lan)(lan)溝中的電(dian)(dian)(dian)纜(lan)(lan)起火(huo)燃燒時(shi)，如果與(yu)其同溝并排敷設的電(dian)(dian)(dian)纜(lan)(lan)有明(ming)顯的著火(huo)可能性，則應將這些電(dian)(dian)(dian)纜(lan)(lan)的電(dian)(dian)(dian)源(yuan)(yuan)(yuan)切斷。電(dian)(dian)(dian)纜(lan)(lan)若是(shi)分(fen)層排列(lie)，則首先(xian)將起火(huo)電(dian)(dian)(dian)纜(lan)(lan)上面的受(shou)熱電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)切斷，然后將與(yu)起火(huo)電(dian)(dian)(dian)纜(lan)(lan)并排的電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)切斷，將起火(huo)電(dian)(dian)(dian)纜(lan)(lan)下面的電(dian)(dian)(dian)纜(lan)(lan)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)切斷。
（3）關閉電(dian)(dian)纜(lan)(lan)(lan)溝(gou)隔火(huo)門或堵死電(dian)(dian)纜(lan)(lan)(lan)溝(gou)兩(liang)端。當電(dian)(dian)纜(lan)(lan)(lan)溝(gou)內的電(dian)(dian)纜(lan)(lan)(lan)起火(huo)時，為了避(bi)免空(kong)氣流通，以利迅速滅火(huo)，應將電(dian)(dian)纜(lan)(lan)(lan)溝(gou)的隔火(huo)門關閉或將兩(liang)端堵死，采用(yong)窒息(xi)的方(fang)法滅火(huo)。
（4）做(zuo)好撲(pu)(pu)(pu)滅電(dian)(dian)(dian)(dian)纜(lan)火災時的(de)(de)人(ren)身防(fang)護。由(you)于電(dian)(dian)(dian)(dian)纜(lan)起火燃燒會產生大(da)量的(de)(de)濃(nong)煙和毒(du)(du)氣，撲(pu)(pu)(pu)滅電(dian)(dian)(dian)(dian)纜(lan)火災時，撲(pu)(pu)(pu)救(jiu)(jiu)(jiu)人(ren)員應(ying)戴防(fang)毒(du)(du)面具。為防(fang)止撲(pu)(pu)(pu)救(jiu)(jiu)(jiu)過程中(zhong)的(de)(de)人(ren)身觸電(dian)(dian)(dian)(dian)，撲(pu)(pu)(pu)救(jiu)(jiu)(jiu)人(ren)員還應(ying)戴橡皮手(shou)套和穿上絕緣靴，若發現高壓(ya)電(dian)(dian)(dian)(dian)纜(lan)一(yi)相接地(di)，撲(pu)(pu)(pu)救(jiu)(jiu)(jiu)人(ren)員應(ying)遵(zun)守：室內不得進(jin)入距故障(zhang)點(dian)(dian)4m以內，室外不得進(jin)入距故障(zhang)點(dian)(dian)8m以內，以免跨步電(dian)(dian)(dian)(dian)壓(ya)及接觸電(dian)(dian)(dian)(dian)壓(ya)傷人(ren)。救(jiu)(jiu)(jiu)護受傷人(ren)員不在此限，但應(ying)采取防(fang)護措施。
（5）撲滅(mie)(mie)電(dian)(dian)纜火(huo)災采(cai)用(yong)(yong)(yong)的滅(mie)(mie)火(huo)器材。撲滅(mie)(mie)電(dian)(dian)纜火(huo)災應采(cai)用(yong)(yong)(yong)滅(mie)(mie)火(huo)機(ji)滅(mie)(mie)火(huo)，如(ru)干(gan)粉滅(mie)(mie)火(huo)機(ji)、“1211”滅(mie)(mie)火(huo)機(ji)、二(er)氧化碳滅(mie)(mie)火(huo)機(ji)等；也可(ke)(ke)使用(yong)(yong)(yong)干(gan)砂或黃(huang)土覆蓋；如(ru)果(guo)用(yong)(yong)(yong)水滅(mie)(mie)火(huo)，使用(yong)(yong)(yong)噴霧水槍；若火(huo)勢猛烈，又不可(ke)(ke)能采(cai)用(yong)(yong)(yong)其他方式撲救，待(dai)電(dian)(dian)源切斷后，可(ke)(ke)向電(dian)(dian)纜溝內灌水，用(yong)(yong)(yong)水將故障封住滅(mie)(mie)火(huo)。
（6）撲救電纜(lan)火災時，禁止用手直接觸摸電纜(lan)鋼鎧和(he)移動電纜(lan)。
