- Ibisobanuro ku bicuruzwa
Icyiciro cya II Ubwoko A2 / B2 Inama yumutekano wibinyabuzima
Inama ishinzwe umutekano w’ibinyabuzima (BSC) ni agasanduku kameze nk'agasanduku, ibikoresho bibi byo guhumanya ikirere bishobora guhagarika umwuka w’ibinyabuzima bishobora kwangirika mu gihe cyo gukora ubushakashatsi.Mu rwego rwa microbiologiya, biomedicine, injeniyeri ya geneti, no gukora ibikomoka ku binyabuzima, ikoreshwa cyane mubushakashatsi bwa siyansi, amabwiriza, ubugenzuzi bw’amavuriro, n’umusaruro.Nibikoresho byingenzi byokwirinda umutekano muri laboratoire biosafety urwego rwambere rwo kurinda.
Imikorere y’inama y’abaminisitiri ishinzwe umutekano:
Akayunguruzo keza cyane (HEPA) mu kirere cyo hanze cyungurura umwuka wo hanze, nuburyo abaminisitiri bashinzwe umutekano w’ibinyabuzima bakora.Ikomeza umuvuduko mubi muri guverinoma kandi ikoresha umwuka uhagaze kugirango urinde abakozi.Byongeye kandi, umwuka w’abaminisitiri ugomba gushungura na filteri ya HEPA hanyuma ukajugunywa mu kirere kugira ngo urusheho kubungabunga ibidukikije.
Amahame yo guhitamo akabati yumutekano wibinyabuzima muri laboratoire yibinyabuzima:
Ntabwo ari ngombwa cyane gukoresha akanama gashinzwe umutekano w’ibinyabuzima cyangwa icyiciro cya mbere cy’umutekano w’ibinyabuzima igihe urwego rwa laboratoire ari 1. Iyo ukorana n’ibikoresho byanduza, inama y’umutekano y’ibinyabuzima yo mu cyiciro cya II ifite umuyaga cyangwa igice cyuzuye igomba gukoreshwa;iyo urwego rwa laboratoire ari urwego rwa 2, inama yumutekano w’ibinyabuzima yo mu cyiciro cya I irashobora gukoreshwa mugihe mikorobe ya mikorobe cyangwa ibikorwa byo kumeneka bishobora kubaho;Gusa ibyiciro bya II-B byuzuye byuzuye (Ubwoko B2) akabati yumutekano wibinyabuzima bigomba gukoreshwa mugihe ukorana na kanseri yica imiti, ibikoresho bya radiyoyoka, hamwe n’umuti uhindagurika.Icyiciro cya II-B cyuzuye (Ubwoko B2) cyangwa icyiciro cya gatatu cy’umutekano w’ibinyabuzima bigomba gukoreshwa muburyo ubwo aribwo bwose bujyanye nibikoresho byanduye mugihe urwego rwa laboratoire ari urwego rwa 3. Urwego rwa III rwuzuye rwuzuye rw’umutekano w’ibinyabuzima rugomba gukoreshwa mugihe urwego rwa laboratoire ruri urwego 4. Iyo abakozi bambaye ibikoresho byiza byo gukingira igitutu, akabati yo mu rwego rwa II-B irashobora gukoreshwa.
Akabati k'umutekano wibinyabuzima muri rusange kagizwe nibice bibiri: agasanduku k'umubiri hamwe na brake.Agasanduku k'umubiri karimo ahanini ibi bikurikira:
1. Sisitemu yo Kwungurura ikirere
Uburyo bwingenzi cyane bwo kwemeza imikorere yibi bikoresho ni sisitemu yo kuyungurura ikirere.Igizwe nu mwuka wo hanze usohora umuyaga, umuyaga utwara ibinyabiziga, umuyoboro wo mu kirere, hamwe na bine muyunguruzi.Intego nyamukuru yaryo ni ugukomeza kuzana umwuka mwiza, kureba niba umuvuduko w’umurimo w’umurimo (vertical airflow) umuvuduko uri munsi ya 0.3 m / s kandi ko urwego rw’isuku rwemejwe ko ruzaba amanota 100.Kugirango wirinde kwanduza ibidukikije, imyuka yo hanze nayo isukurwa icyarimwe.
Akayunguruzo ka HEPA nigice cyingenzi cyakazi cya sisitemu.Ikadiri yacyo ikozwe mubintu bidasanzwe bidafite umuriro, kandi amabati ya aluminiyumu yacitsemo kabiri.Iyi gride yuzuyemo ibirahuri bya fibre fibre sub-uduce, kandi imikorere ya filter irashobora kugera kuri 99,99% kugeza 100%.Mbere yo kuyungurura no kweza ikirere mbere yuko yinjira muyungurura HEPA ishoboka mbere yo kuyungurura cyangwa kubanza kuyungurura ibyinjira mu kirere, bishobora kongera ubuzima bwa filteri ya HEPA.
2. Sisitemu yo mu kirere isohoka hanze
Sisitemu yo hanze yisanduku ya sisitemu igizwe numuyoboro usohoka, umufana, hamwe nagasanduku gasohoka hanze.Kugirango urinde ibyitegererezo nibintu byubushakashatsi muri guverenema, umuyaga usohoka hanze ukuramo umwuka wanduye kumurimo wifashishije akayunguruzo ko hanze.Kurinda uwayikoresheje, umwuka mukarere wemerewe kugenda.
3. Kunyerera imbere ya sisitemu yo gutwara imbere
Sisitemu yo kunyerera imbere yidirishya rya sisitemu igizwe numuryango wimbere wikirahure, moteri yumuryango, uburyo bwo gukurura, shaft yohereza no guhinduranya imipaka.
4. Inkomoko yumucyo nisoko ya UV yumucyo biherereye imbere yumuryango wikirahure kugirango habeho umucyo runaka mubyumba byakazi no guhagarika ameza numwuka mubyumba byakazi.
5. Ikibaho kigenzura gifite ibikoresho nko gutanga amashanyarazi, itara rya ultraviolet, itara ryaka, guhinduranya umuyaga, no kugenzura urujya n'uruza rw'umuryango w'ikirahure.Igikorwa nyamukuru nugushiraho no kwerekana sisitemu imiterere.
Icyiciro cya II A2 umutekano wibinyabuzima kabine / umutekano wibinyabuzima uruganda rwibanze:1. Igishushanyo cyo gutandukanya ikirere kirinda imbere no hanze kwanduzanya, 30% byumwuka uhumeka hanze na 70% byimbere yimbere, umuvuduko mubi wa vertical laminar itemba, nta mpamvu yo gushiraho imiyoboro.
2. Urugi rw'ikirahure rushobora gukingurwa no gufungwa burundu kugirango uhindurwe, hamwe nibimenyetso byerekana uburebure bwo gushyira hejuru.Irashobora kandi guhindurwa hejuru no hasi igashyirwa ahantu hose.3.Kugirango umukoresha yorohereze, amashanyarazi asohoka mumashanyarazi aho akorera hashyizwemo sock idafite amazi hamwe nu mwanda.4.Kugabanya umwanda uhumanya ikirere, akayunguruzo kihariye gashyirwa mu mwuka mwinshi.5.Umwanya wakazi wubatswe na premium 304 ibyuma bidafite ingese bidafite ikizinga, cyiza, kandi kitagira impera zapfuye.Irashobora guhagarika ibibyimba byangiza hamwe nudukoko twangiza kandi biroroshye kwanduza burundu.6.Ifata LED LCD igenzura kandi yubatswe mubikoresho byo kurinda itara rya UV, bishobora gukingurwa gusa umuryango wumutekano ufunze.7.Hamwe nicyambu cya DOP, cyubatswe muburyo butandukanye bwo gupima umuvuduko wa 8, 10 ° inguni ihengamye, bijyanye nigitekerezo cyo gushushanya umubiri wumuntu
