IKhabhinethi Yokuphepha Kwezinto Eziphilayo Ikhabhinethi Yelebhu Yesayensi Yezinto Eziphilayo

IKhabhinethi Yokuphepha Kwezinto Eziphilayo Yesigaba II Uhlobo A2/B2

Ikhabhinethi yokuphepha yaselabhorethri/iklasi iikhabhinethi yokuphepha kwebhayoloji iyadingeka elebhu yezilwane, ikakhulukazi esimweni

Ikhabhinethi ye-biosafety (BSC) ayiyona i-chemical fume hood.

Izimiso zokukhetha amakhabethe okuphepha kwebhayoloji kumalabhorethri e-biosafety:

Uma ileveli yaselabhorethri ingeyodwa, ngokuvamile akudingekile ukusebenzisa ikhabethe lokuphepha kwebhayoloji, noma usebenzise ikhabethe lokuphepha kwebhayoloji lekilasi I.Uma izinga laselabhorethri likuLeveli 2, lapho ama-aerosol amancane noma imisebenzi yokuchafaza kungenzeka, ikhabhinethi yokuphepha kwebhayoloji ye-Class I ingasetshenziswa;lapho usebenzelana nezinto ezithathelwanayo, ikhabhinethi yokuphepha kwebhayoloji ye-Class II enomoya omncane noma ogcwele kufanele isetshenziswe;Uma kubhekwana namakhemikhali abangela umdlavuza, izinto ezikhipha imisebe nezincibilikisi ezishintshashintshayo, amakhabethe okuphepha ebhayoloji e-Biological exhaust (Uhlobo B2) kuphela angasetshenziswa.Uma izinga laselabhorethri likuLeveli 3, iKhabhinethi yokuphepha kwebhayoloji yeSigaba II noma i-Class III kufanele isetshenziswe;yonke imisebenzi ehilela izinto ezithathelwanayo kufanele isebenzise Ikilasi II-B elikhathele ngokuphelele (Uhlobo B2) noma iKhabhinethi yokuphepha kwebhayoloji Yekilasi III.Uma izinga laselabhorethri lisezingeni lesine, kufanele kusetshenziswe ikhabhinethi egcwele yokuphepha yebhayoloji ye-ehaust yeleveli III.Amakhabethe okuphepha ebhayoloji ekilasi II-B angasetshenziswa lapho abasebenzi begqoke izingubo zokuzivikela ezicindezelayo.

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.

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

1. Uhlelo Lokuhlunga Umoya

Uhlelo lokuhlunga umoya luwuhlelo olubaluleke kakhulu lokuqinisekisa ukusebenza kwalo mshini.Iqukethe ifeni yokushayela, ipayipi lomoya, isihlungi somoya esijikelezayo kanye nesihlungi somoya esikhipha umoya sangaphandle.Umsebenzi wayo oyinhloko uwukwenza ngokuqhubekayo umoya ohlanzekile ungene ku-studio, ukuze izinga lokugeleza kwe-downdraft (i-vertical airflow) endaweni yokusebenza lingabi ngaphansi kuka-0.3m / s, futhi ukuhlanzeka endaweni yokusebenza kuqinisekisiwe ukufinyelela amamaki angu-100.Ngesikhathi esifanayo, ukugeleza kwe-exhaust yangaphandle kuyahlanzwa ukuze kuvinjwe ukungcoliswa kwemvelo.

Ingxenye eyinhloko yesistimu isihlungi se-HEPA, esisebenzisa into ekhethekile engashi njengohlaka, futhi ifreyimu ihlukaniswe ngamagridi ngamashidi kathayela we-aluminium, agcwaliswa ngezinhlayiya ezincane ze-emulsified glass fiber, futhi ukusebenza kahle kokuhlunga kungafinyelela. 99.99%~100%.Ikhava yesihlungi sangaphambili noma isihlungi sangaphambili endaweni yokungenisa umoya ivumela umoya ukuthi uhlungwe kusengaphambili futhi ucwenge ngaphambi kokufaka isihlungi se-HEPA, esinganweba impilo yesevisi yesihlungi se-HEPA.

2. Uhlelo lwebhokisi lokukhipha umoya lwangaphandle

Isistimu yebhokisi le-exhaust yangaphandle iqukethe igobolondo lebhokisi le-exhaust elingaphandle, ifeni kanye ne-exhaust duct.I-fan exhaust yangaphandle inikeza amandla okukhipha umoya ongcolile ekamelweni lokusebenza, futhi ihlanzwa ngesihlungi sangaphandle sokukhipha umoya ukuze kuvikelwe amasampula nezinto zokuhlola kukhabhinethi.Umoya osendaweni yokusebenza uyabaleka ukuze uvikele isisebenzisi.

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 ungahanjiswa phansi naphezulu, ungabekwa ngokuzenzakalelayo, kulula ukusebenza, futhi ungavalwa ngokuphelele ukuze uvale inzalo, kanye ne-alamu yomkhawulo wokuphakama kokuma ikhuthaza.3.Isokhethi yokukhipha amandla endaweni yokusebenza ifakwe isokhethi elingangeni manzi kanye nesixhumi esibonakalayo sokukhuculula indle ukuze kunikeze ukunethezeka okuhle ku-opharetha4.Isihlungi esikhethekile sifakwe emoyeni okhipha umoya ukuze kulawuleke ukungcola.5.Indawo yokusebenza yenziwe ngensimbi engagqwali engu-304 esezingeni eliphezulu, ebushelelezi, engenamthungo, futhi engenaziphetho ezifile.Ingahlanzwa kalula futhi ngokuphelele futhi ingavimbela ukuguguleka kwezinto ezibolayo nezibulala amagciwane.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
