A類火災(zāi)：指固體物質(zhì)火災(zāi)。一般在燃燒時(shí)能產(chǎn)生灼熱的余燼。如木材、棉、毛、麻、紙張火災(zāi)等。<br/> B類火災(zāi)：指液體火災(zāi)和可熔化的固體火災(zāi)。如汽油、煤油、原油、甲醇、乙醇、瀝青、石蠟火災(zāi)等。<br/> C類火災(zāi)：指氣體火災(zāi)。如煤氣、天然氣、甲烷、乙烷、丙烷、氫氣火災(zāi)等。<br/> D類火災(zāi)：指金屬火災(zāi)。指鉀、鈉、鎂、鋁鎂合金火災(zāi)等。<br/> E類火災(zāi)（帶電火災(zāi)）：物體帶電燃燒的火災(zāi)。<br/> F類火災(zāi)：烹飪器具內(nèi)的烹飪物（如動(dòng)植物油脂）火災(zāi)。<br/> 2.滅火器的使用范圍<br/> 1)干粉滅火器適用于A、B、C類易燃、可燃固體、液體、氣體及E類帶電設(shè)備的初期火災(zāi)。<br/> 2)二氧化碳滅火器適用于B類可燃液體火災(zāi)及E類帶電設(shè)備火災(zāi)。<br/> 3)泡沫滅火器適用于A類可燃固體火災(zāi)及B類可燃液體火災(zāi)。<br/> 3.滅火器的操作方式<br/> 手提式干粉滅火器的操作方法：<br/> 1)滅火時(shí)將手提式干粉滅火器倒轉(zhuǎn)并搖晃幾次；<br/> 蚌山區(qū)普通閥門多少錢有助生飲 ??由于閥體內(nèi)部以性環(huán)氧樹脂涂裝，閥板的內(nèi)外表面均以橡膠披覆而不至于出現(xiàn)鐵水或腐蝕現(xiàn)象可供生飲。</p><div style="width:100%;text-align:
