液氮罐的放置(zhi)要點(dian)：液氮罐要存放在(zai)(zai)通風良好的陰涼處，不要在(zai)(zai)太陽光下直(zhi)曬。由于其(qi)(qi)制造精密及其(qi)(qi)固有特性，無論在(zai)(zai)使用或存放時，液氮罐均不準傾(qing)斜、橫放、倒(dao)置(zhi)、堆壓、相互撞擊或與(yu)其(qi)(qi)他物件碰撞，要做到輕拿(na)輕放并始終保(bao)持直(zhi)立。

　　液(ye)氮(dan)罐(guan)(guan)(guan)(guan)運輸的要(yao)點：液(ye)氮(dan)罐(guan)(guan)(guan)(guan)在(zai)運輸過程中必(bi)須(xu)裝在(zai)木架(jia)內墊好(hao)軟(ruan)墊，并固定(ding)好(hao)。罐(guan)(guan)(guan)(guan)與罐(guan)(guan)(guan)(guan)之間要(yao)用填充物隔開(kai)，防(fang)(fang)止顛(dian)簸撞(zhuang)擊，嚴防(fang)(fang)傾(qing)倒。裝卸車時要(yao)嚴防(fang)(fang)液(ye)氮(dan)罐(guan)(guan)(guan)(guan)碰擊，更不能在(zai)地上隨意拖拉(la)，以(yi)免減少液(ye)氮(dan)罐(guan)(guan)(guan)(guan)的使用壽命

　　液氮罐的(de)清洗方法：

　　液氮(dan)罐(guan)(guan)(guan)閑置不用(yong)(yong)(yong)時，要用(yong)(yong)(yong)清(qing)水(shui)沖(chong)洗(xi)干凈，將水(shui)排凈，用(yong)(yong)(yong)鼓(gu)風(feng)機吹干，常溫下放置待用(yong)(yong)(yong)。首先把液氮(dan)罐(guan)(guan)(guan)內(nei)提筒取(qu)出，液氮(dan)移出，放置2到(dao)3天，待罐(guan)(guan)(guan)內(nei)溫度上升到(dao)0℃左右，再(zai)(zai)倒(dao)人30℃左右的溫水(shui)，用(yong)(yong)(yong)布擦洗(xi)。若發現個別(bie)融化物質(zhi)粘在內(nei)膽底上，一(yi)定(ding)要細心洗(xi)刷干凈。然后(hou)再(zai)(zai)用(yong)(yong)(yong)清(qing)水(shui)沖(chong)洗(xi)數次，之(zhi)后(hou)倒(dao)置液氮(dan)罐(guan)(guan)(guan)，自(zi)然風(feng)干。
