1. Cov kua nitrogen yuav tsum tau muab khaws cia rau hauv lub thawv ntim kua nitrogen uas tsim nyog (kua nitrogen tank) uas tsim los ntawm cov chaw tsim khoom hauv lub tebchaws, thiab muab tso rau hauv qhov cua zoo, tsaus, thiab txias.
2. Lub thawv ntim kua nitrogen tuaj yeem muab ntim nrog lub tank qub, thiab lub qhov ncauj lub tank yuav tsum muaj qhov sib txawv.Nws yog nruj me ntsis txwv tsis pub kaw lub tank lub qhov ncauj.Txwv tsis pub, vim muaj kev kub ntxhov ntau dhau, kev tawg tuaj yeem tshwm sim.
3. Siv kev tiv thaiv tus kheej thaum tshem cov phev khov ntawm lub tank.Cov kua nitrogen yog cov khoom kub-kub (kub -196 °).Tiv thaiv frostbite thaum siv.
4. Txhawm rau kom cov phev txav mus, cov kua nitrogen yuav tsum tau ntxiv rau cov kua nitrogen hauv lub sijhawm kom ntseeg tau tias cov phev khov hauv lub tank tsis tuaj yeem raug rau sab nraud ntawm cov kua nitrogen.
5. Ua tib zoo saib xyuas cov kua nitrogen txau thiab ua rau neeg mob.Lub boiling point ntawm kua nitrogen yog tsawg.Thaum ntsib cov khoom siab dua li qhov kub thiab txias (qhov kub ib txwm), nws yuav boil, vaporize, los yog txaws.
6. Txheeb xyuas cov thermal rwb thaiv tsev kev ua tau zoo ntawm cov kua nitrogen tank ntau zaus.Yog tias pom tias cov kua nitrogen tank tau frosted rau saum npoo ntawm lub tank plhaub los yog cov kua nitrogen tank nrog cov thermal rwb thaiv tsev tsis zoo thaum siv, nws yuav tsum tau nres thiab hloov tam sim ntawd.
7. Vim nws cov khoom raug thiab cov yam ntxwv ntawm tus kheej, cov kua nitrogen tso tsheb hlau luam tsis raug tso cai rau tilted, muab tso rau hauv kab rov tav, thim rov qab, stacked, sib tsoo los yog sib tsoo nrog lwm yam khoom thaum thauj thiab khaws cia.Thov ua tib zoo saib xyuas thiab nyob twj ywm ncaj.Tshwj xeeb, nws yuav tsum muaj kev ruaj ntseg thaum lub sij hawm thauj mus los los tiv thaiv cov neeg frostbite los yog cov tais diav tom qab pov tseg cov kua nitrogen overturned.
8. Txij li cov kua nitrogen tsis yog cov kab mob bactericidal, tshuaj tua kab mob ntawm cov khoom siv los rau hauv kev sib cuag nrog kua nitrogen yuav tsum tau them sai sai rau.
