   第二(er)，可(ke)(ke)燃(ran)(ran)(ran)性(xing)(xing)氣(qi)體(ti)檢測(ce)(ce)(ce)儀施(shi)工過程(cheng)不(bu)規(gui)范(fan)。施(shi)工過程(cheng)不(bu)規(gui)范(fan)會在使用(yong)過程(cheng)中使可(ke)(ke)燃(ran)(ran)(ran)性(xing)(xing)氣(qi)體(ti)檢測(ce)(ce)(ce)儀探測(ce)(ce)(ce)故障。如可(ke)(ke)燃(ran)(ran)(ran)性(xing)(xing)氣(qi)體(ti)檢測(ce)(ce)(ce)儀未設在設備易于泄漏(lou)可(ke)(ke)燃(ran)(ran)(ran)氣(qi)體(ti)附(fu)近(jin)，或安(an)裝時(shi)與排氣(qi)扇(shan)相鄰(lin)設置，泄漏(lou)的可(ke)(ke)燃(ran)(ran)(ran)氣(qi)體(ti)無法充分擴(kuo)散到(dao)可(ke)(ke)燃(ran)(ran)(ran)性(xing)(xing)氣(qi)體(ti)檢測(ce)(ce)(ce)儀附(fu)近(jin)，從而使泄漏(lou)險情(qing)無法及時(shi)被可(ke)(ke)燃(ran)(ran)(ran)性(xing)(xing)氣(qi)體(ti)檢測(ce)(ce)(ce)儀探知。對于住(zhu)宅內可(ke)(ke)燃(ran)(ran)(ran)性(xing)(xing)氣(qi)體(ti)檢測(ce)(ce)(ce)儀應安(an)裝在廚房(fang)內的燃(ran)(ran)(ran)氣(qi)管道、灶(zao)具附(fu)近(jin)，當住(zhu)戶使用(yong)的是(shi)天然(ran)氣(qi)，燃(ran)(ran)(ran)氣(qi)探測(ce)(ce)(ce)器吸頂(ding)棚安(an)裝距頂(ding)棚300mm以內的地方；當住戶使用的是液化石油氣，燃氣探測器應安裝在距地面300mm以內地方。可燃性氣體檢測儀如不可靠接地，不能消除電磁干擾，必將影響電壓，出現探測數據不準的故障。所以可燃性氣體檢測儀施工過程中應可靠接地。可燃性氣體報警器及接線端子設于易遭受碰撞或易進水處，造成電器線路斷路或短路。焊接必須用無腐蝕的助焊劑，不然接頭處腐蝕脫開或增加線路電阻，影響正常探測。探測器勿掉落或拋落于地。施工完后應進行調試，保證可燃氣體報警器處于正常工作狀態。
