Amazi ya azote (LN2) agira uruhare runini kwisi yubuhanga bwimyororokere ifashwa, nkumuntu ujya muri cryogenic yo kubika ibikoresho by’ibinyabuzima nk’amagi, intanga, na insoro.Gutanga ubushyuhe buke cyane hamwe nubushobozi bwo kugumana ubunyangamugayo, LN2 itanga uburyo bwo kubika igihe kirekire ibyo bigereranyo.Nyamara, guhangana na LN2 bitera ibibazo bidasanzwe, kubera ubushyuhe bwayo bukabije, umuvuduko wo kwaguka byihuse hamwe ningaruka zishobora guterwa no kwimura ogisijeni.Twiyunge natwe mugihe dushakisha ingamba zingenzi zumutekano nuburyo bwiza bukenewe kugirango ibidukikije bibungabungwe neza kandi neza, kurinda abakozi, ndetse nigihe kizaza cyo kuvura uburumbuke.
Haier Biomedical Liquid Amazi ya Azote Igisubizo
Kugabanya ingaruka mu mikorere yicyumba cya Cryogenic
Hariho ingaruka zitandukanye zijyanye no gutunganya LN2, harimo guturika, guhumeka, no gutwika cryogenic.Kubera ko igipimo cyo kwagura ingano ya LN2 kingana na 1: 700 - bivuze ko litiro 1 ya LN2 izava mu kirere kugira ngo itange litiro 700 za gaze ya azote - hagomba kwitabwaho cyane mugihe ukoresha ibirahuri by'ibirahure;igituba cya azote gishobora kumenagura ikirahure, kigakora ibice bishobora gutera imvune.Byongeye kandi, LN2 ifite ubucucike bwumwuka bugera kuri 0,97, bivuze ko butaba buke ugereranije numwuka kandi bizahurira kurwego rwubutaka mugihe ubushyuhe buri hasi cyane.Uku kwirundanya gutera ikibazo cyo guhumeka ahantu hafunzwe, bikagabanya urugero rwa ogisijeni mu kirere.Ibyago bya Asphyxiation byiyongereyeho kurekura byihuse LN2 kugirango habeho ibicu byumwuka.Guhura niyi myuka ikonje cyane, cyane cyane kuruhu cyangwa mumaso - nubwo muri make - bishobora gutera ubukonje bukabije, ubukonje, kwangirika kwinyama cyangwa kwangirika kwamaso.
Imyitozo myiza
Buri vuriro ry’uburumbuke rigomba gukora isuzuma ry’imbere ryerekeye imikorere yicyumba cyayo.Impanuro zuburyo bwo gukora iri suzuma urashobora kuzisanga mubitabo bya Code of Pratique (CP) bivuye mu ishyirahamwe ry’imyuka ya gaze yo mu Bwongereza.1 By'umwihariko, CP36 ni ingirakamaro mu gutanga inama ku bubiko bwa gaze ya kirogenike ku rubuga, kandi CP45 itanga ubuyobozi kuri igishushanyo mbonera cyo kubika cryogenic. [2,3]
OYA.1
Icyumba cya kirogenike cyiza ni kimwe gitanga uburyo bwiza bwo kugerwaho.Harasuzumwa neza gushyira ahabitswe ububiko bwa LN2, kuko bizakenera kuzuzwa binyuze mu bwato bwotswa igitutu.Byiza cyane, icyombo gitanga amazi ya azote kigomba kuba hanze yicyumba cyo kubikamo icyitegererezo, ahantu hafite umwuka mwiza kandi ufite umutekano.Kubisubizo binini byo kubika, ubwato butanga akenshi buhuzwa nubwato bubikwa hakoreshejwe korojene yoherejwe.Niba imiterere yinyubako itemerera ubwato bwogutanga kuba hanze, hagomba kwitabwaho cyane mugihe cyo gukoresha azote yuzuye, kandi hagomba gukorwa isuzuma rirambuye ryibyago, bikubiyemo uburyo bwo gukurikirana no kuvoma.
OYA.2 Guhumeka
Ibyumba byose bya kirogenike bigomba guhumeka neza, hamwe na sisitemu yo kubikuramo kugirango birinde gaze ya azote kwiyongera no kurinda igabanuka rya ogisijeni, bikagabanya ibyago byo guhumeka.Sisitemu nkiyi igomba kuba ikwiranye na gaze ikonje ikonje, kandi igahuzwa na sisitemu yo kugenzura ogisijeni igabanuka kugirango hamenyekane igihe urugero rwa ogisijeni yagabanutse munsi ya 19.5%, muribwo bizatangiza izamuka ry’ivunjisha ry’ikirere.Imiyoboro ikuramo igomba kuba iri kurwego rwubutaka mugihe ibyuma bya depletion bigomba gushyirwa hafi metero 1 hejuru yurwego.Ariko, imyanya nyayo igomba guhitamo nyuma yubushakashatsi burambuye bwurubuga, nkibintu nkubunini bwicyumba nimiterere bizagira ingaruka kumyanya myiza.Impuruza yo hanze nayo igomba gushyirwaho hanze yicyumba, igatanga umuburo wamajwi n'amashusho kugirango bisobanure mugihe ari bibi kwinjira.
OYA.3 Umutekano bwite
Amavuriro amwe arashobora kandi guhitamo guha ibikoresho abakozi ba monitor ya ogisijeni kugiti cyabo no gukoresha sisitemu yinshuti aho abantu bazajya binjira mucyumba cya kirogenike ari babiri, bikagabanya igihe umuntu umwe aba ari mucyumba icyarimwe.Ninshingano yikigo guhugura abakozi kuri sisitemu yo kubika imbeho nibikoresho byayo kandi benshi bahitamo ko abakozi bakora amasomo yumutekano wa azote kumurongo.Abakozi bagomba kwambara ibikoresho byabigenewe byo kurinda (PPE) kugirango birinde gutwikwa kwa kirogenike, harimo kurinda amaso, gants / gauntlet, inkweto zibereye, hamwe n'ikote rya laboratoire.Ni ngombwa ko abakozi bose bahugurwa mbere yuburyo bwo guhangana n’umuriro wa kirogenike, kandi ni byiza ko habaho amazi y’akazuyazi hafi yo koza uruhu niba habaye gutwikwa.
OYA.4 Kubungabunga
Icyombo gikanda hamwe na LN2 kontineri idafite ibice byimuka, bivuze ko gahunda yibanze yo kubungabunga buri mwaka aribyo byose bisabwa.Muri ibi, imiterere ya kirogenike ya hose igomba kugenzurwa, kimwe nibisabwa byose byasimbuwe numutekano wo kurekura umutekano.Abakozi bagomba guhora bagenzura ko nta gace k'ubukonje - haba kuri kontineri cyangwa ku cyombo kigaburira - gishobora kwerekana ikibazo kiri mu cyuho.Hamwe no gusuzuma witonze ibyo bintu byose, hamwe na gahunda yo kubungabunga buri gihe, igitutu gishobora kumara imyaka 20.
Umwanzuro
Guharanira umutekano w’ivuriro ry’uburumbuke icyumba cyo kubungabunga cryo kibika aho LN2 ikoreshwa ni ngombwa cyane.Mugihe iyi blog yagaragaje ibitekerezo bitandukanye byumutekano, ni ngombwa ko buri mavuriro akora isuzuma ryimbere ryimbere kugirango akemure ibisabwa byihariye nibishobora guteza ingaruka.Gufatanya nabashinzwe gutanga inzobere mububiko bukonje, nka Haier Biomedical, ni ngombwa kugirango uhuze ibikenewe neza kandi neza.Mugushira imbere umutekano, gukurikiza imikorere myiza, no gufatanya ninzobere zizewe, amavuriro yuburumbuke arashobora kubungabunga ibidukikije byo kubungabunga cryo umutekano, kurinda abakozi ndetse nubuzima bwibikoresho byimyororokere.
