有的(de)設計(ji)人員認為(wei)，只有可(ke)燃(ran)介質管(guan)道(dao)才需要靜(jing)電接地，非可(ke)燃(ran)介質（如儀表風、工廠(chang)風、氮氣等）管(guan)道(dao)不(bu)需要靜(jing)電接地，這是(shi)不(bu)正確的(de)。

  起火(huo)(huo)(huo)、爆(bao)炸發(fa)生(sheng)(sheng)需(xu)要(yao)三個條件：存在(zai)可燃(ran)(ran)(ran)(ran)介質(zhi)(zhi)，可燃(ran)(ran)(ran)(ran)介質(zhi)(zhi)和(he)(he)氧(yang)氣(qi)接(jie)觸，存在(zai)足夠(gou)引燃(ran)(ran)(ran)(ran)可燃(ran)(ran)(ran)(ran)介質(zhi)(zhi)和(he)(he)氧(yang)氣(qi)混合(he)物的(de)(de)火(huo)(huo)(huo)花(hua)。由靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)引發(fa)的(de)(de)火(huo)(huo)(huo)災(zai)或(huo)爆(bao)炸事故，一定(ding)是(shi)(shi)(shi)由于靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)產(chan)(chan)生(sheng)(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)火(huo)(huo)(huo)花(hua)引燃(ran)(ran)(ran)(ran)或(huo)引爆(bao)泄(xie)漏到(dao)管道(dao)或(huo)設備外部(bu)的(de)(de)可燃(ran)(ran)(ran)(ran)氣(qi)體(ti)或(huo)可燃(ran)(ran)(ran)(ran)粉塵(chen)與氧(yang)氣(qi)的(de)(de)混合(he)物而(er)產(chan)(chan)生(sheng)(sheng)的(de)(de)。只(zhi)要(yao)存在(zai)可燃(ran)(ran)(ran)(ran)氣(qi)體(ti)或(huo)可燃(ran)(ran)(ran)(ran)粉塵(chen)集聚的(de)(de)區(qu)域(yu)，都存在(zai)因(yin)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)或(huo)引發(fa)火(huo)(huo)(huo)災(zai)或(huo)爆(bao)炸的(de)(de)風險。判斷(duan)管道(dao)是(shi)(shi)(shi)否需(xu)要(yao)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)接(jie)地(di)的(de)(de)依據，不是(shi)(shi)(shi)其(qi)內(nei)的(de)(de)介質(zhi)(zhi)是(shi)(shi)(shi)否可燃(ran)(ran)(ran)(ran)，而(er)是(shi)(shi)(shi)其(qi)是(shi)(shi)(shi)否位于火(huo)(huo)(huo)災(zai)和(he)(he)爆(bao)炸危險區(qu)域(yu)內(nei)。SH 3097和(he)(he)HG 20675中(zhong)有明確(que)的(de)(de)規定(ding)，對(dui)爆(bao)炸和(he)(he)火(huo)(huo)(huo)災(zai)危險環(huan)境內(nei)可能產(chan)(chan)坐靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)危害的(de)(de)物體(ti)，應采取工業靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)接(jie)地(di)措(cuo)施。

  有(you)人(ren)認(ren)為(wei)，水是導(dao)(dao)電(dian)(dian)(dian)(dian)的，所以水管(guan)(guan)道、蒸(zheng)汽管(guan)(guan)道不(bu)需要(yao)接地(di)。事(shi)實(shi)上(shang)，蒸(zheng)汽不(bu)是電(dian)(dian)(dian)(dian)的良(liang)導(dao)(dao)體，水本身也(ye)不(bu)導(dao)(dao)電(dian)(dian)(dian)(dian)，導(dao)(dao)電(dian)(dian)(dian)(dian)的是存在(zai)導(dao)(dao)電(dian)(dian)(dian)(dian)離子的水。而很多水，如鍋爐水、除(chu)(chu)氧水、蒸(zheng)汽冷凝液(ye)等都除(chu)(chu)去了大部分(fen)導(dao)(dao)電(dian)(dian)(dian)(dian)離子，其導(dao)(dao)電(dian)(dian)(dian)(dian)性(xing)(xing)能并不(bu)好(hao)。即(ji)使是循(xun)環水，為(wei)了減少換熱設備(bei)結(jie)垢(gou)，也(ye)是經過軟(ruan)化處理，脫除(chu)(chu)了大部分(fen)的鈣鎂(mei)離子。除(chu)(chu)非經過實(shi)驗證(zheng)明工藝裝置所用的水在(zai)管(guan)(guan)道內有(you)良(liang)好(hao)的導(dao)(dao)電(dian)(dian)(dian)(dian)性(xing)(xing)，不(bu)能認(ren)為(wei)水是導(dao)(dao)電(dian)(dian)(dian)(dian)的而取消(xiao)爆炸和火(huo)災(zai)危險區內蒸(zheng)汽和水管(guan)(guan)道的靜(jing)電(dian)(dian)(dian)(dian)接地(di)要(yao)求。
