氣體(ti)(ti)報(bao)(bao)警(jing)器(qi)使用(yong)(yong)(yong)者使用(yong)(yong)(yong)氣體(ti)(ti)探測(ce)器(qi)過程(cheng)(cheng)中(zhong)(zhong)(zhong)，將空(kong)調和(he)(he)取暖(nuan)(nuan)設(she)(she)備靠(kao)近(jin)可(ke)(ke)燃(ran)(ran)性氣體(ti)(ti)報(bao)(bao)警(jing)器(qi)安(an)裝(zhuang)，當使用(yong)(yong)(yong)空(kong)調和(he)(he)取暖(nuan)(nuan)設(she)(she)備的(de)(de)(de)過程(cheng)(cheng)中(zhong)(zhong)(zhong)，如果冷、暖(nuan)(nuan)氣流直接(jie)吹過可(ke)(ke)燃(ran)(ran)氣體(ti)(ti)報(bao)(bao)警(jing)器(qi)，就有(you)可(ke)(ke)能造成可(ke)(ke)燃(ran)(ran)氣體(ti)(ti)報(bao)(bao)警(jing)器(qi)鉑(bo)絲(si)的(de)(de)(de)電(dian)(dian)阻率發生(sheng)變化出(chu)現誤差，因此(ci)可(ke)(ke)燃(ran)(ran)氣體(ti)(ti)報(bao)(bao)警(jing)器(qi)應(ying)(ying)遠離空(kong)調、取暖(nuan)(nuan)設(she)(she)備，避免設(she)(she)置位置不當引(yin)發故障。使用(yong)(yong)(yong)者使用(yong)(yong)(yong)可(ke)(ke)燃(ran)(ran)性氣體(ti)(ti)報(bao)(bao)警(jing)器(qi)過程(cheng)(cheng)中(zhong)(zhong)(zhong)還應(ying)(ying)注(zhu)意防(fang)電(dian)(dian)磁干擾(rao)。可(ke)(ke)燃(ran)(ran)氣體(ti)(ti)報(bao)(bao)警(jing)器(qi)安(an)裝(zhuang)位置、安(an)裝(zhuang)角(jiao)度(du)、防(fang)護措施以及系統布(bu)線(xian)等方面應(ying)(ying)防(fang)電(dian)(dian)磁干擾(rao)。電(dian)(dian)磁環(huan)境對可(ke)(ke)燃(ran)(ran)氣體(ti)(ti)報(bao)(bao)警(jing)器(qi)的(de)(de)(de)影(ying)響途徑主要有(you)三條：空(kong)中(zhong)(zhong)(zhong)電(dian)(dian)磁波干擾(rao)、電(dian)(dian)源及其他輸入輸出(chu)線(xian)上的(de)(de)(de)窄脈沖群以及人(ren)體(ti)(ti)靜(jing)電(dian)(dian)。

可(ke)(ke)燃氣(qi)體(ti)(ti)本身具有(you)一定的(de)擴散性(xing)特征，為(wei)了(le)防(fang)止發(fa)(fa)生泄(xie)漏事故(gu)，通常(chang)情況下，所(suo)采(cai)取的(de)辦法(fa)的(de)關鍵在于有(you)效的(de)控(kong)制其不(bu)斷地(di)進行擴散。往往借助外(wai)力(li)作用(yong)(yong)(yong)(yong)，擴散的(de)速(su)度很快，加(jia)之受到(dao)外(wai)力(li)的(de)推動作用(yong)(yong)(yong)(yong)，可(ke)(ke)燃性(xing)氣(qi)體(ti)(ti)就會迅(xun)速(su)的(de)蔓延，形成燃燒和爆1炸的(de)事故(gu)，這(zhe)(zhe)是一種必然(ran)的(de)現象(xiang)，如何防(fang)范(fan)這(zhe)(zhe)種危險事情的(de)發(fa)(fa)生呢？經(jing)常(chang)檢測(ce)可(ke)(ke)燃性(xing)氣(qi)體(ti)(ti)的(de)空氣(qi)含量，不(bu)能夠超(chao)(chao)標，一旦(dan)超(chao)(chao)標就迅(xun)速(su)報(bao)警，起到(dao)警示作用(yong)(yong)(yong)(yong)，這(zhe)(zhe)就要用(yong)(yong)(yong)(yong)到(dao)可(ke)(ke)燃性(xing)氣(qi)體(ti)(ti)報(bao)警器。
