            硫化氫H2S氣體檢測(cè)管120SC HYDROGEN SULPHIDE 0.005-0.16%,危險(xiǎn)特性:易燃,與空氣混合能形成爆炸性混合物,遇明火、高熱能引起燃燒爆炸。與濃硝酸、發(fā)煙硫酸或其它強(qiáng)氧化劑劇烈反應(yīng),發(fā)生爆炸。氣體比空氣重,能在較低處擴(kuò)散到相當(dāng)遠(yuǎn)的地方,遇明火會(huì)引起回燃。呼吸系統(tǒng)防護(hù):空氣中濃度超標(biāo)時(shí),佩帶過(guò)渡式防毒面具(半面罩)。緊急事態(tài)搶救或撤離時(shí),建議佩帶氧氣呼吸器或空氣呼吸器。
