ILabhoratri yeBiosaftety yeKhabhinethi yeKlasi ye-II Uhlobo lwe-A2 kunye neKlasi ye-II Uhlobo lwe-B2

Udidi lwe-II lweKhabhinethi yoKhuseleko lweBhayoloji ye-A2/B2

Ikhabhinethi yokhuseleko lwebhayoloji (BSC) yibhokisi emile okwebhokisi, uxinzelelo olubi lwezixhobo zokhuseleko lokucoca umoya ezinokunqanda amasuntswana ebhayoloji anokuba yingozi ukuba aphume abe ngumphunga ngexesha lemisebenzi yovavanyo.Kwimimandla ye-Microbiology, i-biomedicine, ubunjineli bemfuza, kunye nokuveliswa kweemveliso zebhayoloji, isetyenziswa kakhulu kufundo lwesayensi, imiyalelo, ukuhlolwa kwezonyango, kunye nemveliso.Sesona siqwenga sisisiseko sesixhobo sokhuseleko kwilabhoratri ye-biosafety yenqanaba lokuqala lomqobo lokhuselo.

Ukusebenza kweKhabhinethi yoKhuseleko lwebhayoloji:

Isihluzo somoya esisebenza kakuhle kakhulu (HEPA) kumoya wangaphandle sihluza umoya wangaphandle, yindlela esebenza ngayo ikhabhinethi yokhuseleko lwebhayoloji.Igcina uxinzelelo olubi ngaphakathi kwekhabhathi kwaye isebenzisa ukuhamba komoya okuthe nkqo ukukhusela abasebenzi.Ukongeza, umoya wekhabhathi kufuneka uhluzwe ngesihluzo se-HEPA kwaye emva koko ukhutshelwe emoyeni ukukhusela okusingqongileyo.

Imigaqo yokukhetha iikhabhathi zokhuseleko lwebhayoloji kwiilabhoratri zokhuseleko lwendalo:

Ngokuqhelekileyo akubalulekanga ukuqesha ikhabhinethi yokhuseleko lwebhayoloji okanye iklasi I yekhabhinethi yokhuseleko lwebhayoloji xa inqanaba lelebhu liku-1. Xa usebenza ngezinto ezosulelayo, iKhabhinethi yokhuseleko lwebhayoloji yodidi II enenxalenye okanye epheleleyo yokungena komoya kufuneka isetyenziswe;xa inqanaba lebhubhoratri likwiNqanaba lesi-2, iKhabhinethi yoKhuseleko lwebhayoloji yeKlasi I ingasetyenziswa xa i-microbial aerosols okanye imisebenzi yokutshiza inokwenzeka;Kuphela i-Class II-B yokukhupha ngokupheleleyo (uHlobo lwe-B2) iikhabhinethi zokhuseleko lwebhayoloji kufuneka zisetyenziswe ngelixa kusetyenzwa ngeekhemikhali ze-carcinogens, izinto ze-radioactive, kunye nezinyibilikisi eziguquguqukayo.IKhabhinethi yoKhuseleko lwebhayoloji yoMgangatho wesi-II ephelelwe ngokupheleleyo kufuneka isetyenziswe kuzo naziphi na iinkqubo ezibandakanya izinto ezosulelayo xa inqanaba lelebhu likwiNqanaba lesi-3. Inqanaba III elipheleleyo lekhabhathi yokhuseleko lwebhayoloji kufuneka isetyenziswe xa inqanaba lelebhu likwiNqanaba lesi-3. inqanaba 4. Xa abasebenzi benxibe izixhobo ezikhuselayo zoxinzelelo, iikhabhinethi zokhuseleko lwebhayoloji zeKlasi II-B zinokuqeshwa.

IKhabhinethi yoKhuseleko lwendalos (BSC), ekwaziwa ngokuba ziiKhabhinethi zoKhuseleko lweBiological, zibonelela ngabasebenzi, imveliso, kunye nokhuseleko lokusingqongileyo ngokusebenzisa i-laminar airflow kunye ne-HEPA filtration yelebhu ye-biomedical/microbiological.

Iikhabhathi zokhuseleko lwebhayoloji zibandakanya iinxalenye ezimbini: umzimba webhokisi kunye nesibiyeli.Umzimba webhokisi ubandakanya ikakhulu ezi zinto zilandelayo:

1. Inkqubo yoHluzo loMoya

Eyona ndlela ibalulekileyo yokuqinisekisa ukusebenza kwesi sixhobo yinkqubo yokucoca umoya.Yenziwe ngesihluzo somoya sangaphandle, i-fan yokuqhuba, i-air duct, kunye nezihluzo zomoya ezine zizonke.Eyona njongo yayo iphambili kukuzisa rhoqo umoya ococekileyo, ukuqinisekisa ukuba iqondo lokuqukuqela lokwehla kwendawo yokusebenza (i-airflow ethe nkqo) alikho ngaphantsi kwe-0.3 m/s kwaye inqanaba lokucoceka liqinisekisiwe ukuba liya kuba ngamabakala ali-100.Ukuze kuthintelwe ukungcoliseka kokusingqongileyo, ukuhamba kombhobho wangaphandle nako kuyacocwa ngaxeshanye.

Isihluzi se-HEPA sesona sahlulo sisebenzayo senkqubo.Isakhelo saso senziwe ngezinto ezikhethekileyo ezingatshiyo, kwaye amacangci e-aluminiyam enziwe ngamacangci ayahlula abe ziigridi.Ezi grids zizaliswe nge-emulsified glass fiber sub-particles, kunye nokusebenza kakuhle kwesihluzi kunokufikelela kwi-99.99% ukuya kwi-100%.Ukuhluza kwangaphambili kunye nokucoca umoya phambi kokuba ungene kwisihluzo se-HEPA kwenziwa ukuba kwenzeke ngesigqubuthelo sesihluzo sangaphambili okanye isihluzi sangaphambili kwigalelo lomoya, esinokunyusa ubomi besihluzo se-HEPA.

2. Inkqubo yebhokisi yomoya yokukhupha yangaphandle

Inkqubo yebhokisi yokukhupha yangaphandle yenziwe ngumbhobho wokukhupha, ifeni, kunye negobolondo lebhokisi yokukhupha ngaphandle.Ukukhusela iisampulu kunye nezinto zokulinga kwikhabhinethi, i-fan exhaust yangaphandle ikhupha umoya ongcolileyo kwindawo yokusebenza ngoncedo lwesihlungi sangaphandle.Ukukhusela umqhubi, umoya kwindawo yokusebenza uvumelekile ukuba uhambe.

3. Inkqubo yokuqhuba ifestile yangaphambili

Inkqubo yefestile yokutyibilika yangaphambili yenziwe ngumnyango weglasi wangaphambili, ucango lwemoto, indlela yokutsala, ishaft yokuhambisa kunye nokutshintsha umda.

4. Umthombo wokukhanyisa kunye nomthombo wokukhanya we-UV ubekwe ngaphakathi komnyango weglasi ukuqinisekisa ukukhanya okuthile kwigumbi lokusebenza kunye nokucoca itafile kunye nomoya kwigumbi lokusebenza.

5. Iphaneli yokulawula inezixhobo ezifana nokunikezelwa kwamandla, isibane se-ultraviolet, isibane sokukhanyisa, i-fan switch, kunye nokulawula ukuhamba komnyango weglasi wangaphambili.Umsebenzi ophambili kukuseta nokubonisa ubume benkqubo.

Udidi II A2 ikhabhathi yokhuseleko lwebhayoloji/abalinganiswa abaphambili bekhabhathi yokhuseleko lwebhayoloji:1. Uyilo lokuhlukaniswa kwekhethini lomoya luthintela ukungcoliseka kwangaphakathi nangaphandle, i-30% yokuhamba komoya ikhutshwe ngaphandle kunye ne-70% yomjikelezo wangaphakathi, uxinzelelo olubi lokuhamba kwe-laminar, akukho mfuneko yokufaka imibhobho.

2. Ucango lweglasi lunokuvulwa kwaye luvalwe ngokupheleleyo ukwenzela ukuvala inzala, kunye nokubekwa kwesilumkiso sothintelo lokuphakama kweempawu.Isenokulungelelaniswa phezulu naphantsi kwaye ibekwe naphi na.3.Ukulungelelaniswa komsebenzisi, i-socket yokuphuma kwamandla kwindawo yokusebenzela ifakwe i-socket engenamanzi kunye ne-interface yogutyulo.4.Ukunciphisa ungcoliseko lokukhutshwa, isihluzo esithile sifakwe kwi-air exhaust air.5.Indawo yokusebenza yakhiwe nge-premium ye-304 yentsimbi engenamthungo, ethambileyo, kwaye engenaziphelo ezifileyo.Isenokunqanda imixube ekhukulisekayo kunye nezibulali ntsholongwane ekukhukuliseni kwaye kulula ukuyibulala iintsholongwane ngokupheleleyo.6.Yamkela ulawulo lwepaneli ye-LCD ye-LED kunye nesixhobo sokukhusela isibane se-UV esakhelwe ngaphakathi, esinokuvulwa kuphela xa umnyango wokhuseleko uvaliwe.7.Ngezibuko lokubona i-DOP, igeyiji yoxinzelelo olwakhelwe ngaphakathi olwakhelwe ngaphakathi.
