Tiv thaiv koj cov qauv, koj pab neeg, thiab koj cov kev tshawb fawb nrog cov khoom siv tau
Nyob rau hauv txhua lub chaw kuaj ua hauj lwm nrog cov khoom siv roj ntsha, kom muaj kev nyab xeeb yog qhov tseem ceeb. IbKev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb Txiaj Ntsig (BSC)Yog ib qho tseem ceeb ntawm cov khoom tsim qauv los muab kev tiv thaiv rau tus neeg siv, kev sim, thiab ib puag ncig. Yog tias koj xav tias yuav ib qho BSC, nkag siab tias nws cov haujlwm, cov yam ntxwv tseem ceeb yog rau kev txiav txim siab paub tias ua tau raws li kev txiav txim siab uas ua tau raws li koj li kev xav tau.
Dab tsi yog aKev Nyab Xeeb Kev Ruaj Ntseg?
Kev siv roj ntsha kev nyab xeeb yog ib qhoNtawm cov txheej txheemQhov chaw tus neeg teb xov tooj thiab cov ntaub ntawv siv roj ntsha yog cais los ntawm cov kev taw qhia txaus los ntawm kev ua kom tsis muaj menyuam, hepa {{{} wiled cua. Cov teeb tsa no txo cov peev txheej rau cov txheej txheem paug los yog inadvertent qhia ntawm tus neeg teb xov tooj rau cov kab mob methorganism.
BSCS tsis yog yooj yim laminar ntws hoods; Lawv tau tsim tawm los muab ntau theem kev tiv thaiv, nyob ntawm lawv cov chav kawm thiab kev teeb tsa.
Cov chav kawm ntawm Biosafety Tub Ceev Xwm
Biosafety tub kawm tau faib rau hauv peb chav kawm tseem ceeb (I, II, thiab III) raws li lawv cov velocities, cov yam ntxwv, thiab tsim.
Chav Kawm Kuv BSCS:
PubCov neeg ua haujlwm thiab kev tiv thaiv ib puag ncigTab sis tsis txhob tiv thaiv cov qauv los ntawm kev sib kis. Lawv tsim nyog rau kev ua haujlwm nrog cov neeg sawv cev tsawg.
Hoob II BSCS:
Kev pubKev tiv thaiv rau tus neeg teb xov tooj, cov khoom lag luam, thiab ib puag ncigCov. Lawv tau muab faib ua ntxiv rau hauv hom (piv txwv li, A1, A2, B1, B2, C1) raws li cov qauv Airflow thiab kev tso pa tawm. Chav kawm no feem ntau siv hauv microbiology thiab kev ua haujlwm ntawm tes ua haujlwm.
- Ntaus A2 / B2: Piv txwv li, A2 / B2 hom kev nyab xeeb kev nyab xeeb muab kev tiv thaiv kev tiv thaiv kev tiv thaiv, thiab ib puag ncig, thiab ib puag ncig, thiab ib puag ncig, thiab ib puag ncig, thiab ib puag ncig, thiab ib puag ncig, thiab yog qhov tsim nyog siv rau kev siv cov tshuaj uas tsis muaj kuab lom.
- Qee qhov kev kawm qib II BSCS, ua haujlwm los ntawm recirculating 70% ntawm cov huab cua hauv lub txee thaum sib npaug ntawm 30% los ntawm kev ntsuas kev nyab xeeb, ntsuas kev nyab xeeb thiab ua haujlwm.
Chav Kawm Ntawv III BSCS:
Muab covqib siab tshaj plaws ntawm kev nyab xeebCov. Lawv tau muab tso rau hauv, xau -} nruj, thiab cia ib qho ua haujlwm los ntawm cov hnab looj tes. Lawv feem ntau yog siv rau high - kev pheej hmoo muaj kuab lom roj ntsha?
Cov kev txiav txim siab tseem ceeb thaum xaiv BSC
Xaiv txoj cai BSC cuam tshuam nrog ntau yam:
Ergonomics thiab cov neeg siv kev nyab xeeb nta:
Xav txog qhov txawv txav zoo li sab hauv teeb pom kev zoo (piv txwv li,Illuminations ntau dua 1000 feeb), cov qib hauv suab nrov (piv txwv li,Tsawg dua 56 DBA), thiab qhov ntev thiab qhov ntev los ua kom muaj kev nyab xeeb thiab kev nyab xeeb. Cov khaub ncaws kom raug thiab tsim nyog tiv thaiv cov khaub ncaws (zoo li tsis - Woven plua plav tawm thiab microbial los ntawm cov txee.
01
Pom kev ua tau zoo:
Saib rau txee ua ke nrogHepa (High {- Kev ua tau zoo plug nteg pa) lossis ulpa (ultra-} Cov taub lim dej qis)Cov. Cov ntxaij lim dej no tau tsim los rau cov lus lim cov lus, suav nrog cov kab mob me, nrog kev ua haujlwm siab. Piv txwv li, qee cov txee feature Ulpa lim uas cov phiaj xwm me me li 0.12μm nrog kev ua tau zoo tshaj 99.999%. HEPA cov ntxaij lim dej yog npaj rau cov khoom ntim tau muaj qhov loj ntawm 0.3 μm.
02
Kev siv tau thiab ntawv pov thawj:
Ib qho BSC yuav tsum raug tsim kho, siv tau, thiab tau lees paub tsis tu ncua kom ntseeg tau tias nws ua raws li cov lus qhia tshwj xeeb.
03
Hom haujlwm thiab cov ntawv thov:
Xav txog qhov xwm txheej ntawm koj txoj kev sim. Piv txwv li, yog tias koj ua haujlwm nrog cov tshuaj lom neeg lom los yog radionuclides, chav kawm ua pa rau sab nraud tom qab HEPA / ulpa pom, yuav tsim nyog. BSCS yog kev siv thoob plaws los muab kev tiv thaiv tseem ceeb thaum ua haujlwm nrog cov ntaub ntawv sib kis.
04
Biosafety qib sib xyaw:
Nco ntsoov tias BSC ua ke nrog covBiosafety Qib (BSL)ntawm koj kev ua haujlwm. BSCS yog qhov tseem ceeb rau kev tswj hwm kev sim biosafety, nrog BSL-2 xav tau cov haujlwm uas feem ntau ua haujlwm hauv lawv, thiab BSL-4 xav tau ntau yam muaj.
05
Siv thiab kho kom raug
Ib BSC tsuas yog ua tau zoo raws li nws cov kev siv thiab upkeep. Nco ntsoov ua raws li cov khoom lag luam tsim qauv thiab cov txheej txheem kev ua haujlwm cov qauv. Cov kev qhia tseem ceeb muaj xws li:
Kev rhuav tshem:
Kev rho tshuaj paug tsis tu ncua, xws li siv autoclaves rau cov khoom sib kis ua ntej pov tseg, yog qhov tseem ceeb heev.
Aseptic Technique:
Tso cai rau lub txee kom khiav tsawg kawg 10-15 feeb ua ntej siv los purge qee qhov teeb meem thiab teeb tsa cua zoo.
Ua ntej -}} siv tu:
So cov chaw sab hauv nrog cov tshuaj tua kab mob uas tsim nyog ua ntej thiab tom qab siv.
Kev nqis peev hauv kev nyab xeeb, nqis peev hauv qhov zoo
Xaiv txoj cai muaj txoj cai kev nyab xeeb roj ntsha txee yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam rau kev tshawb fawb thiab kev nyab xeeb ntawm koj cov neeg ua haujlwm. Los ntawm ua tib zoo xav txog koj cov kev xav tau hais txog theem Biosafety, kev thov, thiab cov yam ntxwv ua tau zoo, koj tuaj yeem xaiv ib qho kev tiv thaiv BSC uas muab cov kev tiv thaiv kev tsim nyog rau xyoo tom ntej.
Qhov kev nyab xeeb ua ntej yam tsis muaj kev sib txawv ntawm kev ua kom muaj kev nyab xeeb ntawm kev nyab xeeb roj ntsha hnub no kom pom lub zoo meej rau koj sim.
