Ikhabhinethi ye-BSC Class II Type A2 Biological Safety

IKhabhinethi Yokuphepha Kwebhayoloji Yesigaba II Uhlobo A2/B2

Ikhabhinethi yokuphepha yaselabhorethri/iklasi iikhabethe lokuphepha kwezinto eziphilayo liyadingeka elebhu yezilwane, ikakhulukazi esimweni

Uma ungena elabhorethri yocwaningo, kukhona ucezu lwemishini evame ukubizwa ngamagama amaningi ahlukene: i-cell culture hood, i-tissue culture hood, i-laminar flow hood, i-PCR hood, ibhentshi elihlanzekile, noma ikhabethe le-biosafety.Into ebalulekile okumele uyiqaphele, noma kunjalo, ukuthi akuwona wonke lawa "ama-hood" adalwe ngokulinganayo;empeleni, banamakhono okuvikela ahluke kakhulu.Intambo evamile ukuthi imishini inikeza ukugeleza komoya kwe-laminar endaweni yokusebenza "ehlanzekile", kodwa kubalulekile ukwazi ukuthi akuzona zonke izinto ezihlinzeka ngabasebenzi abengeziwe noma ukuvikelwa kwemvelo. amalabhorethri ukuze ahlinzeke ngabasebenzi, imvelo, nokuvikelwa komkhiqizo.Ama-BSC amaningi (isb., Ikilasi II kanye Nekilasi III) asebenzisa izihlungi ze-particulate air (HEPA) ezisebenza kahle kakhulu kukho kokubili i-exhaust kanye nesistimu yokunikezela ukuvimbela ukuchayeka ezingozini eziphilayo.

IKhabhinethi Yezokuphepha Eziphilayo (i-BSC), eyaziwa nangokuthi yiKhabhinethi ye-Biosafety isetshenziswa kakhulu ukuphatha amasampula ebhayoloji ye-pathogenic noma izinhlelo zokusebenza ezidinga indawo yokusebenza eyinyumba.Ikhabhinethi yokuphepha yebhayoloji idala ukungena nokugeleza komoya okwehlayo okunikeza ukuvikelwa komqhubi.

Ikhabhinethi yokuphepha kwebhayoloji (BSC) iwukulawula kobunjiniyela okuyinhloko okusetshenziselwa ukuvikela abasebenzi kuma-biohazardous noma ama-ejenti athathelwanayo kanye nokusiza ukugcina ukulawulwa kwekhwalithi yezinto ezisetshenziswayo njengoba ihlunga kokubili ukungena nokukhipha umoya.Ngezinye izikhathi ibizwa ngokuthi ukugeleza kwe-laminar noma i-tissue culture hood.edinga isilinganiso sokuvikela, njengemithi, ikhemisi, ucwaningo lwesayensi nokunye.

Ikhabhinethi yokuphepha kwebhayoloji (BSC), ebizwa nangokuthi ikhabethe le-biosafety, iyihood noma ibhokisi lamagilavu ​​elifanele ukuphathwa ngokuphephile kanye nokusetshenziswa kwamasampula ebhayoloji, amagciwane, izinto ezithathelwanayo, njenge-COVID-19, nezinye izinto ezaziwa ukuthi zibanga umdlavuza ( carcinogens) noma ukukhubazeka kokuzalwa (teratogens).Izidingo zekhabhinethi yokuphepha kwebhayoloji zichazwa Amazinga Okuphepha Ebhayoloji (BSL), ahlukanisa ubungozi bezempilo nokuphepha phakathi kwendawo Yekilasi 1, Ikilasi 2, Nekilasi 3, kanye Nekilasi lesi-4.

I-Class II Biological Safety Cabinet systems ihlinzeka ngomoya wokuphakelwa ohlungiwe we-HEPA kanye nomoya wokukhipha umoya ohlungiwe we-HEPA.Amakhabethe e-biosafety e-Class-2 ayadingeka lapho kukhona amagciwane ayingozi ngokusesilinganisweni, njenge-Staphylococcus aureus.Izinhlobo ezingaphansi ze-Biosafety ze-Class-2 zifaka phakathi u-A1, A2, B1, B2, kanye nokulungiselelwa kwe-C1.Amakhabethe e-Biosafety Ekilasi II A2 azungeza kabusha u-70% womoya ubuyele endaweni yokusebenza kuyilapho eqeda u-30% osele.Amakhabethe e-Biosafety e-Class II B2 akhipha ngokushesha umoya ongu-100% ushiya indawo yokusebenza.Amakhabethe e-biosafety Ekilasi II C1 avunyelwe yi-NSF/ANSI 49 futhi ayakwazi ukushintsha phakathi kokucushwa kwe-A2 ne-B2.

AmaKhabhinethi e-Biosafety (BSC), abuye aziwe ngokuthi amaKhabhinethi Okuphepha Kwezinto Eziphilayo, ahlinzeka ngabasebenzi, umkhiqizo, nokuvikelwa kwemvelo ngokusebenzisa ukugeleza komoya kwe-laminar kanye nokuhlunga kwe-HEPA ngelebhu ye-biomedical/microbiological.

Ikhabethe lezokuphepha lebhayoloji yekilasi II A2/abalingiswa abakhulu bekhabethe lokuphepha kwebhayoloji:

1. Idizayini yokuhlukanisa ikhethini lomoya ivimbela ukungcoliswa kwangaphakathi nangaphandle, u-30% wokugeleza komoya ukhishwa ngaphandle kanye no-70% wokujikeleza kwangaphakathi, ukugeleza kwe-laminar okunengcindezi eqondile, asikho isidingo sokufaka amapayipi.

2. Umnyango wengilazi ungahanjiswa phansi naphezulu, ungabekwa ngokuzenzakalelayo, kulula ukusebenza, futhi ungavalwa ngokuphelele ukuze uvale inzalo, kanye ne-alamu yomkhawulo wokuphakama kwendawo.

3. Isokhethi yokukhipha amandla endaweni yokusebenza ifakwe isokhethi elingangeni manzi kanye nesixhumi esibonakalayo sokukhuculula indle ukuze kuhlinzekwe lula kakhulu ku-opharetha.

4. Isihlungi esikhethekile sifakwe emoyeni wokukhipha ukuze kulawuleke ukungcola.

5. Indawo yokusebenza yenziwe ngensimbi engagqwali engu-304 yekhwalithi ephezulu, ebushelelezi, engenamthungo, futhi engenazo iziphetho ezifile.Ingahlanzwa kalula futhi ngokuphelele futhi ingavimbela ukuguguleka kwama-ejenti agqwalisayo kanye nezibulala-magciwane.

6. Yamukela isilawuli sephaneli ye-LCD ye-LED kanye nedivayisi yokuvikela isibani se-UV eyakhelwe ngaphakathi, engavulwa kuphela lapho umnyango wokuphepha uvaliwe.

7. Ngembobo yokutholwa ye-DOP, igeji yokucindezela ehlukile eyakhelwe ngaphakathi.

8, 10° i-engeli yokutsheka, ngokuhambisana nomqondo wokuklama umzimba womuntu
