2、不要把安全帽歪戴，也不要把帽沿戴在腦后方。否則，會(huì)下降安全帽關(guān)于沖擊的防護(hù)作用。 3、安全帽的下領(lǐng)帶有必要扣在頜下，并系牢，松緊要適度。這樣不致于被勁風(fēng)吹掉，或許是被其他障礙物碰掉，或許由于頭的前后擺動(dòng)，使安全帽墜落。 4、安全帽體頂部除了在帽體內(nèi)部安裝了帽襯外，有的還開(kāi)了小孔通風(fēng)。在使用時(shí)不要為了透氣而隨意再行開(kāi)孔。由于這樣作將會(huì)便帽體的強(qiáng)度下降。安全工器具可分為絕緣安全用具，和一般防護(hù)安全用具兩大類。江西高壓設(shè)備檢測(cè)多少錢</p><p
