Ukusetyenziswa ngokuchanekileyo kweflask yeDewar

Ngophuhliso oluqhubekayo lweshishini legesi ekhethekileyo, kukho imfuno ekhulayo yeenqanawa zoxinzelelo ezifanaDewaresetyenziselwa ukuthwala iigesi ezikhethekileyo kushishino, kunye nesiphumo salo kwakhona ngokwandayo evelele, nangona iimveliso isitya ucinezelo ezahlukeneyo ezifana Dewar Iphumelele uphuhliso oluhle kushishino, kodwa ulwazi oluqhelekileyo malunga dewar kuqikelelwa ukuba bambalwa kakhulu abantu baqonde. Nangona isetyenziswa kakhulu, ayiqhelekanga kubomi bethu bemihla ngemihla. Kule nto kufuneka sazi iinkqubo zokusebenza zeesilinda zegesi. Yiba nokuqonda okuthile.
　　
1. Qinisekisa ukuba indawo yokusebenza kwenqanawa yoxinzelelo ineemeko ezintle zomoya, kwaye umxholo we-oksijini emoyeni kufuneka ube ngaphezu kwe-18% (i-volume concentration).
　　
2. Zonke izixhobo (kubandakanywa iziqhagamshelo, imibhobho kunye neevalvu) kwitanki yeDewar kufuneka zingangcoliswa ngezinto ezinokutsha ezifana neoyile negrisi.
　　
3. Ivalve yesilinda segesi kufuneka ivulwe ngokucothayo ngesandla. Ukuba ivalve yonakele, usenokungakwazi ukuyivula ngesandla. Musa ukusebenzisa isitshixo okanye ezinye izinto ukuyinyanzela ukuba ivuleke. Kufuneka uqhagamshelane neisitya soxinzeleloumenzi ngoko nangoko.4. Ukuba ivalve kunye nezinye izixhobo zinomkhenkce, iindlela ezifanelekileyo ezifana namanzi ashushu kufuneka zisetyenziswe ukukhenkceza. Musa ukusebenzisa idangatye elivulekileyo ukunyibilika, kwaye musa ukusebenzisa izando okanye ezinye izinto ukubetha iDewar. Thintela nayiphi na indawo yetanki\/dewar ekubeni ingalungiswa okanye iqiniswe phantsi koxinzelelo.

5. Musa ukusebenzisa ulwelo lwenitrogen Dewar kwiindawo ezinemeko yokungena komoya engekho mgangathweni njengamagumbi angaphantsi, amagumbi angaphantsi komhlaba okanye iindawo zokuhlala.
