氬氣對人的危害和處理方法

氬氣對人的危害和處理方法,

氬本身無毒,但在高濃度時有窒息作用。當空氣中氬氣濃度高于33%時就有窒息的危險。當氬氣濃度超過50%時,出現嚴重癥狀,濃度達到75%以上時,能在數分鐘內死亡。液氬可以傷皮膚,眼部接觸可引起炎癥。所以生產場所要通風,并且,從事與氬氣有關的技術人員,每年定期進行職業病體檢,確保身體健康。氬氣為惰性氣體對人體無直接危害。但是,如果工業使用后,產生的廢氣則對人體危害很大,會造成矽肺、眼部損壞等情況。急救措施皮膚接觸:接觸液氬,可形成凍傷。用水沖洗患處,就醫。眼睛接觸:液氬濺入眼內,可引起炎癥,翻開眼瞼用水沖洗,就醫。吸入:將患者移至空氣新鮮處。呼吸停止,施行呼吸復蘇術,心跳停止,施行心肺復蘇術,就醫。

消防措施危險特性:氬本身不燃燒,但盛裝氬氣容器與設備遇明火高溫可使器內壓力急劇升高至爆炸,應用水冷卻火中容器。

滅火方法及滅火劑:用水冷卻火中容器,用著火環境相適應的滅火劑。常氣壓下無毒。高濃度時,使氧分壓降低而發生窒息。氬濃度達50%以上,引起嚴重癥狀;75%以上時,可在數分鐘內死亡。當空氣中氬濃度增高時,先出現呼吸加速,注意力不集中,共濟失調。繼之,疲倦乏力、煩躁不安、惡心、嘔吐、昏迷、抽搐,以至死亡。液態氬可致皮膚凍傷;眼部接觸可引起炎癥儲存于陰涼、通風的庫房。遠離火種、熱源。庫溫不宜超過30℃。應與易(可)燃物分開存放,切忌混儲。儲區應備有泄漏應急處理設備。
