Ukongeza kwimingcipheko yokhuseleko eqhelekileyo kwiindawo ezininzi zokusebenza zemihla ngemihla (ezinje ngeengozi zombane kunye nomlilo), iilabhoratri zenkcubeko yeeseli zikwanazo iingozi ezininzi kunye nobungozi obunxulumene nokuphathwa kunye nokuphathwa kweeseli zabantu okanye zezilwanyana kunye nezicubu, kunye netyhefu, eyonakalisayo okanye eguquguqukayo. izinyibilikisi.Iireagents.Iingozi eziqhelekileyo kukugqojozwa ngempazamo kweenaliti okanye ezinye izinto ezibukhali ezingcolisekileyo, ukuchitheka kunye nokuchaphaza esikhumbeni nakwinwebu, ukungenwa ngemibhobho yomlomo, kunye nokuphefumla ii-aerosols ezosulelayo.
Injongo esisiseko yayo nayiphi na inkqubo ye-biosafety kukunciphisa okanye ukuphelisa ukuvezwa kwabasebenzi baselabhoratri kunye nokusingqongileyo kwangaphandle kwii-arhente zebhayoloji ezinokuba yingozi.Eyona nto ibalulekileyo yokhuseleko kwiilabhoratri zenkcubeko yeeseli kukuthotyelwa okungqongqo kunye neenkqubo kunye nobuchule obuqhelekileyo bebhayoloji.
1. Inqanaba lokhuseleko lwebhayoloji
Imimiselo yase-US kunye neengcebiso malunga ne-biosafety ziqulethwe kwi-"Biosafety kwi-Microbiology kunye ne-Biomedical Laboratories" uxwebhu olulungiselelwe ngamaZiko oLawulo lweSifo (CDC) kunye neZiko lezeMpilo leSizwe (NIH) kwaye lipapashwe yinkonzo yeSebe lezeMpilo lase-US.Olu xwebhu luchaza amanqanaba amane anyukayo okubamba, abizwa ngokuba ngamanqanaba e-biosafety 1 ukuya ku-4, kwaye ichaza izenzo ze-microbiological, izixhobo zokhuseleko, kunye nemilinganiselo yokukhusela isibonelelo kumanqanaba ahambelanayo omngcipheko ahambelana nokuphatha iintsholongwane ezithile.
1.1 iNqanaba loku-1 loKhuseleko lwendalo (BSL-1)
I-BSL-1 linqanaba elisisiseko lokhuseleko elixhaphakileyo kuphando oluninzi nakwiilabhoratri zeklinikhi, kwaye ilungele ii-reagents ezaziwa ngokuba azibanga zifo kubantu abaqhelekileyo nabasempilweni.
1.2 iNqanaba lesi-2 loKhuseleko lwendalo (BSL-2)
I-BSL-2 ilungele iziyobisi ezinobungozi obuphakathi ezaziwa ukuba zibangele izifo zabantu zobunzima obuhlukeneyo ngokutya okanye nge-transdermal okanye i-mucosal exposure.Uninzi lweelebhu zenkcubeko yeeseli kufuneka zifezekise ubuncinci be-BSL-2, kodwa iimfuno ezithile zixhomekeke kumgca weseli osetyenziswayo kunye nohlobo lomsebenzi owenziweyo.
1.3 iNqanaba lesi-3 loKhuseleko lwebhayoloji (BSL-3)
I-BSL-3 ilungele iintsholongwane zendalo okanye zangaphandle ezinesakhono sosulelo lwe-aerosol eyaziwayo, kunye neentsholongwane ezinokuthi zibangele usulelo olumandundu nolunokubulala.
1.4 iNqanaba lesi-4 loKhuseleko lwendalo (BSL-4)
I-BSL-4 ifanelekile kubantu abanomngcipheko ophezulu kunye neentsholongwane zangaphandle ezingaphathwanga ezibangela izifo ezisongela ubomi ngokusebenzisa i-aerosols ezosulelayo.Ezi arhente zithintelwe kwiilabhoratri ezivaleleke kakhulu.
2. IPhepha leDatha yoKhuseleko (SDS)
I-data sheet yokhuseleko (SDS), eyaziwa ngokuba yi-material safety data sheet (MSDS), ifom equlethe ulwazi malunga neempawu zezinto ezithile.I-SDS ibandakanya idatha yenyama efana ne-melting point, indawo yokubilisa, kunye ne-flash point, ulwazi malunga ne-toxicity, i-reactivity, imiphumo yempilo, ukugcinwa kunye nokulahlwa kwezinto, kunye nezixhobo zokukhusela ezicetyiswayo kunye neenkqubo zokuphatha ukuvuza.
3. Izixhobo zoKhuseleko
Izixhobo zokhuseleko kwiilebhu zenkcubeko yeeseli zibandakanya izithintelo ezinkulu, ezinjengeekhabhathi zokhuseleko lwebhayoloji, izikhongozeli ezivaliweyo, kunye nolunye ulawulo lobunjineli oluyilelwe ukuphelisa okanye ukunciphisa ukuvezwa kwezinto ezinobungozi, kunye nezixhobo zokuzikhusela (PPE) ezihlala zidityaniswa nezixhobo ezinkulu zokukhusela.Iikhabhathi zokhuseleko lwebhayoloji (oko kukuthi, iihoods zeseli) zezona zixhobo zibalulekileyo, ezinokulawula ukutshiza okusulelayo okanye ii-aerosols eziveliswa ziinkqubo ezininzi ze-microbial kwaye zithintele inkcubeko yakho yeeseli ukuba ingcoliseke.
4. Izixhobo zoKhuseleko zoMntu (PPE)
Izixhobo zokukhusela umntu (PPE) ngumqobo othe ngqo phakathi kwabantu kunye neearhente eziyingozi.Ziquka izinto zokuzikhusela, ezifana neeglavu, iidyasi zelebhu kunye neegawuni, izigqubuthelo zezihlangu, iibhutsi, izixhobo zokuphefumla, izikhuselo zobuso, iindondo zokhuseleko okanye iiglasi.Ngokuqhelekileyo zisetyenziselwa kunye neekhabhinethi zokhuseleko lwebhayoloji kunye nezinye izixhobo eziqulethe i-reagents okanye izinto ezicutshungulwayo.
