I-Laboratory Biosaftety Cabinet Class II Uhlobo A2 Kanye Nekilasi II Uhlobo lwe-B2

IKhabhinethi Yokuphepha Kwezinto Eziphilayo Yesigaba II Uhlobo A2/B2

Ikhabhinethi yokuphepha kwebhayoloji (i-BSC) iyithuluzi lokuphepha elimise okwebhokisi, elinengcindezi engafanele yokuhlanza umoya elingamisa izinhlayiya ezithile zebhayoloji ezingaba yingozi ukuthi zihwamuke phakathi nomsebenzi wokuhlola.Ezizindeni ze-microbiology, i-biomedicine, ubunjiniyela bezakhi zofuzo, kanye nokukhiqizwa kwemikhiqizo yebhayoloji, isetshenziswa kakhulu ocwaningweni lwesayensi, ekufundiseni, ekuhlolweni komtholampilo, nasekukhiqizeni.Iwucezu olubaluleke kakhulu lwegiya lokuvikela ukuphepha endaweni yokuvimbela i-biosafety yezinga lokuqala lokuvikela.

Ukusebenza kweKhabhinethi Lokuphepha Kwebhayoloji:

Isihlungi somoya se-particulate esisebenza kahle kakhulu (i-HEPA) emoyeni wangaphandle sihluza umoya ongaphandle, okuyindlela ikhabhinethi yokuphepha yebhayoloji esebenza ngayo.Igcina ingcindezi engemihle ngaphakathi kwekhabhinethi futhi isebenzisa ukugeleza komoya okuqondile ukuze ivikele abasebenzi.Ukwengeza, umoya wekhabhinethi kufanele uhlungwe ngesihlungi se-HEPA bese ukhishelwa emkhathini ukuze uvikele imvelo.

Izimiso zokukhetha amakhabethe okuphepha kwebhayoloji kumalabhorethri e-biosafety:

Ngokuvamile akudingekile ukuqasha ikhabhinethi yokuphepha kwebhayoloji noma ikhabhinethi yokuphepha kwebhayoloji yekilasi I lapho izinga laselabhorethri liku-1. Lapho kusetshenzwa ngezinto ezithathelwanayo, ikhabhinethi yokuphepha kwebhayoloji yeSigaba II esinomoya omncane noma ogcwele kufanele sisetshenziswe;lapho izinga laselabhorethri likuLeveli 2, ikhabhinethi yokuphepha kwebhayoloji Yekilasi I ingasetshenziswa lapho ama-aerosol amancane noma imisebenzi yokufafaza kungenzeka;Amakhabethe okuphepha ezinto eziphilayo Ekilasi II-B kuphela okufanele asetshenziswe ngenkathi kusetshenzwa ngamakhemikhali abangela umdlavuza, izinto ezikhipha imisebe, nezinyibilikisi ezishintshashintshayo.Ikhabethe elikhathele ngokuphelele leSigaba II-B (Uhlobo B2) noma iKhabhinethi yeSigaba III yokuphepha kwebhayoloji kufanele isetshenziselwe noma yiziphi izinqubo ezihilela izinto ezithathelwanayo lapho ileveli yaselabhorethri ikuLeveli 3. Ikhabethe eliphelele le-exhaust eliphelele lokuphepha kwebhayoloji kufanele lisetshenziswe lapho izinga laselabhorethri likhona. Izinga lesi-4. Uma abasebenzi begqoke okokuvikela ukucindezela okuhle, amakhabethe okuphepha ebhayoloji eSigaba II-B angaqashwa.

IKhabhinethi ye-Biosafetys (BSC), eyaziwa nangokuthi amaKhabhinethi Okuphepha Kwezinto Eziphilayo, inikeza izisebenzi, umkhiqizo, nokuvikelwa kwemvelo ngokugeleza komoya okune-laminar kanye nokuhlunga kwe-HEPA ngelebhu ye-biomedical/microbiological.

Amakhabethe okuphepha kwezinto eziphilayo ngokuvamile anezingxenye ezimbili: umzimba webhokisi kanye nobakaki.Umzimba webhokisi uhlanganisa ikakhulukazi izakhiwo ezilandelayo:

1. Uhlelo Lokuhlunga Umoya

Indlela ebaluleke kakhulu yokuqinisekisa ukusebenza kwale mishini uhlelo lokuhlunga umoya.Yakhiwe ngesihlungi somoya esikhipha umoya wangaphandle, ifeni yokushayela, ipayipi lomoya, nezihlungi zomoya ezine sezizonke.Inhloso yawo enkulu ukuletha umoya ohlanzekile njalo, ukuqinisekisa ukuthi izinga lokugeleza kwendawo yokusebenza (ukugeleza komoya okuqondile) alikho ngaphansi kuka-0.3 m/s nokuthi izinga lenhlanzeko liqinisekisiwe ukuthi lingamabanga ayi-100.Ukuze ugweme ukungcoliswa kwemvelo, ukugeleza kwe-exhaust yangaphandle nakho kuhlanzwa kanyekanye.

Isihlungi se-HEPA siyingxenye eyinhloko yokusebenza yesistimu.Uhlaka lwayo lwenziwe ngezinto ezihlukile ezingashi, futhi amashidi e-aluminium kathayela aluhlukanisa abe amagridi.Lawa magridi agcwaliswa ngezinhlayiya ezincane ze-emulsified glass fiber, futhi ukusebenza kahle kwesihlungi kungafinyelela ku-99.99% kuya ku-100%.Ukuhlunga kusengaphambili nokuhlanza umoya ngaphambi kokuba ungene kusihlungi se-HEPA kwenziwa kwenzeke ngekhava yesihlungi sangaphambili noma isihlungi sangaphambili ekufakweni komoya, okungakhuphula isikhathi sokuphila sesihlungi se-HEPA.

2. Uhlelo lwebhokisi lokukhipha umoya lwangaphandle

Isistimu yebhokisi le-exhaust yangaphandle yenziwe nge-exhaust duct, ifeni, kanye negobolondo lebhokisi le-exhaust langaphandle.Ukuze kuvikelwe amasampula nezinto zokuhlola kukhabhinethi, isiphephetha-moya sangaphandle sikhipha umoya ongcolile endaweni yokusebenza ngosizo lwesihlungi se-exhaust sangaphandle.Ukuvikela opharetha, umoya endaweni yokusebenza uvunyelwe ukuba uhambe.

3. Isistimu yokushayela iwindi yangaphambili eshelelayo

Isistimu yokushayela iwindi elishelelayo langaphambili yakhiwe ngomnyango wengilazi wangaphambili, isicabha semoto, indlela yokudonsa, shaft yokudlulisela kanye nokushintsha komkhawulo.

4. Umthombo wokukhanyisa kanye nomthombo wokukhanya kwe-UV kutholakala ngaphakathi komnyango wengilazi ukuze kuqinisekiswe ukukhanya okuthile egumbini lokusebenza nokubulala amagciwane etafuleni nomoya egumbini lokusebenza.

5. Iphaneli yokulawula inamadivayisi afana nokunikezwa kwamandla, isibani se-ultraviolet, isibani esikhanyisayo, i-fan switch, nokulawula ukunyakaza komnyango wengilazi yangaphambili.Umsebenzi oyinhloko ukusetha nokubonisa isimo sohlelo.

Isigaba II A2 ikhabethe lokuphepha kwebhayoloji/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 ungase uvulwe futhi uvalwe ngokuphelele ukuze uvale inzalo, kanye namasignali okukhawulela ukuphakama kokubekwa.Ingabuye ilungiswe phezulu naphansi futhi ibekwe noma kuphi.3.Ukuze kube lula ku-opharetha, isokhethi yokukhipha amandla endaweni yokusebenza ifakwe isokhethi elingangeni manzi kanye nesixhumi esibonakalayo sokukhuculula indle.4.Ukuze kuncishiswe ukungcola okuphumayo, isisefo esithile sifakwa emoyeni wokukhipha umoya.5.Indawo yokusebenza yakhiwe ngensimbi engagqwali engu-304 eyi-premium engenamthungo, eshelelayo, futhi engenazo iziphetho ezifile.Ingase ivimbele ukuguguleka kwezithako nezibulala-magciwane ekugugulekeni futhi kulula ukuyibulala amagciwane ngokugcwele.6.Yamukela isilawuli sephaneli ye-LCD ye-LED kanye nedivayisi yokuvikela isibani se-UV eyakhelwe ngaphakathi, engavulwa kuphela lapho umnyango wokuphepha uvaliwe.7.Ngembobo etholwayo ye-DOP, igeji yengcindezi eyakhelwe ngaphakathi ehlukile.8, i-engeli etshekile engu-10°, ngokuhambisana nomqondo wokuklama umzimba womuntu
