全氟己酮滅火后如何確保環(huán)境安全?標(biāo)準(zhǔn)解讀與監(jiān)測(cè)對(duì)策

點(diǎn)擊次數(shù):129  更新時(shí)間:2025-09-04

全氟己酮是什么?為何被稱為“綠色滅火劑"?

全氟己酮,化學(xué)名稱為 全氟-2-甲基-3-戊酮(C6F12O),是一種新型潔凈氣體滅火劑,常溫下呈液態(tài),但因其 蒸發(fā)熱僅為水的1/25,蒸汽壓是水的25倍,極易揮發(fā)成氣體,從而迅速吸收熱量,中斷燃燒鏈?zhǔn)椒磻?yīng),達(dá)到滅火目的。

相比傳統(tǒng)的哈龍、七氟丙烷等滅火劑,全氟己酮具備以下環(huán)保優(yōu)勢(shì):

•臭氧消耗潛能值(ODP)為0

•全球變暖潛能值(GWP)僅為1(遠(yuǎn)低于七氟丙烷的3220)

•不導(dǎo)電、無殘留、不腐蝕設(shè)備

•對(duì)人體相對(duì)友好,但仍不可忽視高濃度下的吸入風(fēng)險(xiǎn)

正因如此,全氟己酮廣泛應(yīng)用于 數(shù)據(jù)中心、電力設(shè)施、精密儀器場(chǎng)所、儲(chǔ)能電站 等對(duì)滅火后環(huán)境要求很高的區(qū)域。


全氟己酮滅火后為何仍存在安全隱患?

雖然全氟己酮本身毒性較低,但其滅火設(shè)計(jì)濃度為 4%~6%(體積比),實(shí)際滅火后,局部濃度可能高達(dá) 10%~20%,遠(yuǎn)超安全范圍。人員若在未充分通風(fēng)的情況下進(jìn)入,可能面臨以下風(fēng)險(xiǎn):

•呼吸困難、頭暈等輕度中毒癥狀

•麻醉效應(yīng),影響神經(jīng)反應(yīng)與判斷力

•在密閉空間內(nèi),存在窒息或氧氣稀釋風(fēng)險(xiǎn)

因此,滅火后 不能立即進(jìn)入現(xiàn)場(chǎng),必須經(jīng)過科學(xué)評(píng)估與監(jiān)測(cè),確保環(huán)境安全后方可恢復(fù)作業(yè)。


如何確保全氟己酮滅火后環(huán)境安全?

一、實(shí)時(shí)監(jiān)測(cè)氣體濃度

安裝專業(yè)的全氟己酮?dú)怏w檢測(cè)報(bào)警儀,是確保環(huán)境安全的核心措施之一。以贏潤(rùn)集團(tuán)研發(fā)生產(chǎn)的ERUN-PG51PFC固定在線式全氟己酮?dú)怏w檢測(cè)報(bào)警儀為例,可以連續(xù)實(shí)時(shí)在線監(jiān)測(cè)環(huán)境空氣中的全氟己酮?dú)怏w的濃度值及泄漏狀況,在檢測(cè)到全氟(2-甲基-3-戊酮)蒸汽濃度達(dá)到或超過正常濃度值,就會(huì)在現(xiàn)場(chǎng)發(fā)出聲光報(bào)警,自動(dòng)聯(lián)鎖控制電磁閥排氣風(fēng)機(jī)進(jìn)行工作,并可同步在值班室監(jiān)控主機(jī)上實(shí)時(shí)顯示全氟己酮?dú)怏w濃度值和報(bào)警狀態(tài),廣泛適用于發(fā)電廠變電所/站(干式變壓器、濕式變壓器、高低壓開關(guān)柜)、配電室(配電柜/箱、電氣柜/電容柜、電纜)、數(shù)據(jù)基站、儲(chǔ)能電站、計(jì)算機(jī)房、充電樁等電力行業(yè)滅火系統(tǒng)中十二氟-2-甲基-3-戊酮 C6F12O氣體濃度值的檢測(cè)。

二、加強(qiáng)通風(fēng)換氣

滅火后的首要任務(wù)是 強(qiáng)制通風(fēng),以降低全氟己酮在空氣中的殘留濃度??刹捎靡韵路绞剑?/span>

•開啟 防爆軸流風(fēng)機(jī)、換氣扇

•使用 移動(dòng)式工業(yè)排風(fēng)設(shè)備

•自然通風(fēng)條件不足時(shí),應(yīng)延長(zhǎng)通風(fēng)時(shí)間至 2小時(shí)以上

通風(fēng)后,應(yīng)再次通過檢測(cè)儀器確認(rèn)濃度已降至安全水平。


三、人員進(jìn)入前安全評(píng)估

在進(jìn)入滅火區(qū)域前,必須滿足以下條件:

•全氟己酮?dú)怏w濃度 低于 0.5% VOL 或更低

•氧氣濃度保持在 19.5%~23.5% 之間

•無明顯異味、刺激性感覺

•有專人監(jiān)護(hù),佩戴必要的防護(hù)裝備(如防毒面具)


國(guó)家與行業(yè)標(biāo)準(zhǔn)如何規(guī)定?

目前,雖然我國(guó)尚未專門針對(duì)全氟己酮制定詳細(xì)濃度限值標(biāo)準(zhǔn),但可參考以下規(guī)范:

•《GB 50016-2014 建筑設(shè)計(jì)防火規(guī)范》:強(qiáng)調(diào)滅火后應(yīng)進(jìn)行環(huán)境檢測(cè)與通風(fēng)

•《GB/T 50493-2019 石油化工可燃?xì)怏w和有毒氣體檢測(cè)報(bào)警設(shè)計(jì)標(biāo)準(zhǔn)》:要求在可能產(chǎn)生有毒氣體區(qū)域安裝固定式氣體檢測(cè)報(bào)警裝置

•《GBZ 2.1-2019 工作場(chǎng)所有害因素職業(yè)接觸限值》:雖未明確全氟己酮限值,但建議參考類似惰性氣體或麻醉性氣體控制原則


全氟己酮作為高效環(huán)保的滅火介質(zhì),其滅火后環(huán)境安全管理不可忽視。通過 安裝固定式氣體檢測(cè)報(bào)警儀、實(shí)施強(qiáng)制通風(fēng)、設(shè)定合理的人員進(jìn)入標(biāo)準(zhǔn),并嚴(yán)格遵循國(guó)家與行業(yè)技術(shù)規(guī)范,可最大限度降低殘留氣體帶來的安全風(fēng)險(xiǎn),確保人員健康與設(shè)備完好。

只有在科學(xué)防控的基礎(chǔ)上,才能讓這一“綠色滅火技術(shù)"真正做到安全無害,為現(xiàn)代高要求場(chǎng)所提供可靠保障。
