IKhabhinethi yoKhuseleko lweBhayoloji ye-BSC ye-2 Uhlobo lwe-A2

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

Ikhabhathi yokhuseleko lwebhubhoratri / iklasi iikhabhathi yokhuseleko lwebhayoloji iyimfuneko kwilebhu yezilwanyana, ngakumbi kwimeko

Xa uhamba kwilabhoratri yophando, kukho isixhobo sesixhobo esihlala sibizwa ngamagama amaninzi ahlukeneyo: i-cell culture hood, i-tissue culture hood, i-laminar flow hood, i-PCR hood, ibhentshi ecocekileyo, okanye ikhabhinethi ye-biosafety.Into ebalulekileyo ukuba uyiqaphele, nangona kunjalo, ukuba akuzona zonke ezi "hoods" ezidalwe ngokulinganayo;eneneni, banamandla okukhusela ahlukeneyo.Intambo eqhelekileyo kukuba izixhobo zibonelela ngokuhamba komoya we-laminar kwindawo yokusebenza "ecocekileyo", kodwa kubalulekile ukwazi ukuba ayizizo zonke izixhobo ezibonelela ngabasebenzi abongezelelweyo okanye ukukhuselwa kwendalo. iilabhoratri zokubonelela abasebenzi, indalo, kunye nokhuseleko lwemveliso.Uninzi lwe-BSCs (umzekelo, iKlasi ye-II kunye neKlasi ye-III) zisebenzisa izihluzi eziphezulu ze-particulate air (HEPA) kuzo zombini i-exhaust kunye nenkqubo yokubonelela ukukhusela ukuvezwa kwi-biohazards.

IKhabhinethi yoKhuseleko lweBhayoloji (i-BSC), ekwaziwa njengeKhabhinethi yoKhuseleko lweNdalo isetyenziselwa ukuphatha iisampulu zebhayoloji ezibangela izifo okanye izicelo ezifuna indawo ekusetyenzwa kuyo engenazintsholongwane.Ikhabhinethi yokhuseleko lwebhayoloji idala ukungena kunye nokuhla komoya obonelela ngokhuseleko lwabaqhubi.

Ikhabhinethi yokhuseleko lwebhayoloji (BSC) lulawulo lobunjineli oluphambili olusetyenziselwa ukukhusela abasebenzi ngokuchasene ne-biohazardous okanye iiarhente ezosulelayo kunye nokunceda ukugcina ulawulo lomgangatho wezinto ezisetyenzwayo njengoko zihluza zombini ukungena kunye nokuphuma komoya.Ngamanye amaxesha kuthiwa yi-laminar flow okanye i-tissue culture hood.edinga umlinganiselo wokukhusela, njengamayeza, ikhemesti, uphando lwezenzululwazi kunye nokunye.

Ikhabhinethi yokhuseleko lwebhayoloji (BSC), ekwabizwa ngokuba yikhabhathi yokhuseleko lwebhayoloji, yihood okanye ibhokisi yeglove ilungele ukuphathwa ngokukhuselekileyo kunye nokukhohlisa iisampulu zebhayoloji, iibhaktheriya, izinto ezosulelayo, ezinjenge-COVID-19, kunye nezinye izinto ezaziwa ngokubangela umhlaza. carcinogens) okanye iziphene zokuzalwa (teratogens).Iimfuno zekhabhinethi yokhuseleko lwebhayoloji zichazwa ngamaNqanaba oKhuseleko lwe-Biological (BSL), eyahlula ingozi yempilo kunye nokhuseleko phakathi kweKlasi 1, iKlasi 2, kunye neKlasi yesi-3, kunye neemeko zeKlasi yesi-4.

Iisistim zeKhabhinethi zoKhuseleko lweBhayoloji yodidi lweSibini zibonelela nge-HEPA ecocekileyo yokubonelela ngomoya kunye ne-HEPA ecocekileyo yokukhupha umoya.Iikhabhinethi ze-Biosafety ze-Class-2 ziyafuneka phambi kwee-microbes ezinobungozi obuphakathi, ezifana ne-Staphylococcus aureus.I-Class-2 ye-biosafety sub-types iquka i-A1, i-A2, i-B1, i-B2, kunye noqwalaselo lwe-C1.Iikhabhinethi zeKlasi ye-II A2 ye-biosafety iphinda ijikeleze i-70% yomoya ibuyele kwindawo yokusebenza ngelixa ikhupha i-30 eseleyo.Iikhabhinethi zeClass II B2 ze-biosafety ngokukhawuleza zikhupha i-100% yomoya oshiya indawo yokusebenza.Iikhabhinethi ze-biosafety ze-Class II C1 zi-NSF/ANSI 49 ezivunyiweyo kwaye ziyakwazi ukuguqula phakathi kwe-A2 kunye ne-B2 yoqwalaselo.

IiKhabhinethi zoKhuseleko lweBhayoloji (BSC), ezikwabizwa ngokuba ziiKhabhinethi zoKhuseleko lweBhayoloji, zibonelela ngabasebenzi, imveliso, kunye nokhuseleko lokusingqongileyo ngokuqhutywa kwe-laminar airflow kunye ne-HEPA yokucoca ilebhu yebhayomedical/microbiological.

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 lunokuthi luhanjiswe phezulu naphantsi, lunokubekwa ngokungqongqo, lusebenza lula, kwaye lunokuvalwa ngokupheleleyo ukwenzela ukuvala inzala, kunye ne-alarm yobude bokumisa iphakamisa.

3. I-socket yokuphuma kwamandla kwindawo yokusebenza ixhotyiswe ngesokhethi engenamanzi kunye ne-interface yogutyulo ukubonelela ngokulula kakhulu kumqhubi.

4. Isihluzo esikhethekileyo sifakwe kwi-exhaust air ukulawula ungcoliseko oluphumayo.

5. Indawo yokusebenza yenziwe ngentsimbi ye-304 ephezulu, egudileyo, engenamthungo, kwaye ingenasiphelo.Inokukhutshwa ngokulula kwaye ngokucokisekileyo iintsholongwane kwaye inokuthintela ukukhukuliseka kwezinto ezitshabalalisayo kunye nezibulali ntsholongwane.

6. Yamkela ulawulo lwepaneli ye-LCD ye-LED kunye nesixhobo sokukhusela isibane se-UV esakhelwe ngaphakathi, esinokuvulwa kuphela xa umnyango wokhuseleko uvaliwe.

7. Nge-port yokufumanisa i-DOP, i-gauge eyakhelwe-ngaphakathi yokwahlukana koxinzelelo.

I-8, i-10 ° i-angle yokuthambeka, ngokuhambelana nomxholo woyilo womzimba womntu
