有的設計人(ren)員認為(wei)，只有可燃介(jie)質管道才需要靜(jing)電接(jie)地(di)(di)，非可燃介(jie)質（如儀表(biao)風、工廠風、氮(dan)氣等）管道不需要靜(jing)電接(jie)地(di)(di)，這是不正確的。

  起火(huo)、爆(bao)炸發生需要(yao)(yao)三(san)個條(tiao)件：存(cun)在可(ke)(ke)燃(ran)(ran)(ran)介(jie)質(zhi)，可(ke)(ke)燃(ran)(ran)(ran)介(jie)質(zhi)和(he)氧(yang)(yang)氣接(jie)觸，存(cun)在足夠(gou)引燃(ran)(ran)(ran)可(ke)(ke)燃(ran)(ran)(ran)介(jie)質(zhi)和(he)氧(yang)(yang)氣混(hun)合(he)物的(de)(de)(de)火(huo)花。由(you)靜(jing)電(dian)(dian)(dian)引發的(de)(de)(de)火(huo)災或爆(bao)炸事故，一定(ding)是(shi)由(you)于靜(jing)電(dian)(dian)(dian)放電(dian)(dian)(dian)產生電(dian)(dian)(dian)火(huo)花引燃(ran)(ran)(ran)或引爆(bao)泄漏到管道或設備(bei)外部的(de)(de)(de)可(ke)(ke)燃(ran)(ran)(ran)氣體或可(ke)(ke)燃(ran)(ran)(ran)粉(fen)塵與氧(yang)(yang)氣的(de)(de)(de)混(hun)合(he)物而(er)產生的(de)(de)(de)。只要(yao)(yao)存(cun)在可(ke)(ke)燃(ran)(ran)(ran)氣體或可(ke)(ke)燃(ran)(ran)(ran)粉(fen)塵集(ji)聚的(de)(de)(de)區(qu)域(yu)(yu)，都存(cun)在因靜(jing)電(dian)(dian)(dian)放電(dian)(dian)(dian)或引發火(huo)災或爆(bao)炸的(de)(de)(de)風險(xian)(xian)。判斷管道是(shi)否需要(yao)(yao)靜(jing)電(dian)(dian)(dian)接(jie)地的(de)(de)(de)依據(ju)，不是(shi)其內的(de)(de)(de)介(jie)質(zhi)是(shi)否可(ke)(ke)燃(ran)(ran)(ran)，而(er)是(shi)其是(shi)否位于火(huo)災和(he)爆(bao)炸危(wei)(wei)(wei)險(xian)(xian)區(qu)域(yu)(yu)內。SH 3097和(he)HG 20675中(zhong)有明確(que)的(de)(de)(de)規定(ding)，對爆(bao)炸和(he)火(huo)災危(wei)(wei)(wei)險(xian)(xian)環境內可(ke)(ke)能產坐(zuo)靜(jing)電(dian)(dian)(dian)危(wei)(wei)(wei)害(hai)的(de)(de)(de)物體，應采取工業靜(jing)電(dian)(dian)(dian)接(jie)地措(cuo)施。

  有人認為(wei)(wei)，水(shui)(shui)(shui)(shui)(shui)(shui)是導(dao)電(dian)(dian)(dian)的(de)(de)，所以水(shui)(shui)(shui)(shui)(shui)(shui)管道(dao)(dao)(dao)、蒸(zheng)汽(qi)管道(dao)(dao)(dao)不需要接地(di)。事實(shi)上(shang)，蒸(zheng)汽(qi)不是電(dian)(dian)(dian)的(de)(de)良導(dao)體(ti)，水(shui)(shui)(shui)(shui)(shui)(shui)本身也不導(dao)電(dian)(dian)(dian)，導(dao)電(dian)(dian)(dian)的(de)(de)是存(cun)在導(dao)電(dian)(dian)(dian)離(li)子(zi)的(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)。而(er)很多(duo)水(shui)(shui)(shui)(shui)(shui)(shui)，如鍋爐水(shui)(shui)(shui)(shui)(shui)(shui)、除氧水(shui)(shui)(shui)(shui)(shui)(shui)、蒸(zheng)汽(qi)冷凝(ning)液等都(dou)除去了大部分(fen)導(dao)電(dian)(dian)(dian)離(li)子(zi)，其導(dao)電(dian)(dian)(dian)性(xing)能(neng)并不好。即使是循環水(shui)(shui)(shui)(shui)(shui)(shui)，為(wei)(wei)了減少換(huan)熱設(she)備結垢，也是經過(guo)軟化處理，脫除了大部分(fen)的(de)(de)鈣(gai)鎂離(li)子(zi)。除非經過(guo)實(shi)驗證明工藝裝置所用(yong)的(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)在管道(dao)(dao)(dao)內有良好的(de)(de)導(dao)電(dian)(dian)(dian)性(xing)，不能(neng)認為(wei)(wei)水(shui)(shui)(shui)(shui)(shui)(shui)是導(dao)電(dian)(dian)(dian)的(de)(de)而(er)取消爆炸和火(huo)災危險區(qu)內蒸(zheng)汽(qi)和水(shui)(shui)(shui)(shui)(shui)(shui)管道(dao)(dao)(dao)的(de)(de)靜電(dian)(dian)(dian)接地(di)要求。
