Cov chav kawm sib txawv ntawm BSC cov chav kawm tau piav qhia - Chav I, Chav Kawm Hoob II & Chav III
Apr 05, 2025| Nkag siab txog qhov sib txawv ntawm ntau yamKev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb Txiaj Ntsig (BSC)yog qhov tseem ceeb rau kev ua kom cov kev tiv thaiv zoo thiab ua raws. Txhua chav kawm ntawm BSC muaj cov qib sib txawv ntawm kev tiv thaivCov neeg ua haujlwm, khoom lag luam, thiab ib puag ncig, ua rau nws tseem ceeb heev los xaiv hom yog rau koj qhov kev kuaj sim kev kuaj mob.
Vim li cas kev nkag siab BSC cov chav kawm tseem ceeb
Xaiv lub chav kawm BSC yog kom ntseeg tau:
-
Kev tiv thaiv kom tsim nyog: Kev tiv thaiv kev paug cov qauv, tiv thaiv cov neeg ua haujlwm los ntawm cov neeg sawv cev phom sij, thiab saib xyuas kev nyab xeeb ib puag ncig.
-
Ua raws li cov qauv: Tswj cov lus qhia zoo li NSF / ansi 49 thiab EN 12469.
-
Qhov kev ua tau zoo tshaj plaws: Ntais ntawv cov kab txee kom raug nrog cov ntawv thov npaj, txhim kho lab efficiency.
Txheej txheem cej luam ntawm biological kev nyab xeeb txee chav kawm
Kev Nyab Xeeb Kev Nyab Xeeb Khoom Siv tau muab faib uaPeb Chav Kawm: Chav Kawm I, Chav Kawm II, thiab Chav IIICov. Txhua lub hom phiaj tshwj xeeb thiab muab qib kev tiv thaiv sib txawv.
1. Chav Iiological txee
Kev tiv thaiv tau muab
-
✅ Kev Tiv Thaiv Cov Zej Zog
-
Kev tiv thaiv ib puag ncig
-
❌ Tsis muaj cov khoom tiv thaiv
Nws ua haujlwm li cas
-
Huab cua yog kos rau hauv cov txee los ntawm kev qhib pem hauv ntej thiab lim ua ntej ua sab sab.
-
Muaj kev tiv thaiv zoo rau aerosols thiab kev txheeb teeb meem.
-
Haum rau cov txheej txheem uas tsim cov aerosols lossis kov cov khoom txaus ntshai.
Cov Ntawv Thov
-
Kov cov neeg sawv cev kom tsawg.
-
Cov khoom siv xws li centrifuges, mixers, lossis sib xyaw uas herosol tiam yog qhov yuav.
2. Chav Kawm 2 Kev Ruaj Ntseg Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb
Chav Kawm Hoob II BSCS yog cov khoom siv uas feem ntau hauv kev tshawb fawb, chaw kho mob, thiab tshuaj napragtories. Lawv tau subdivided rau hauvNtaus A1, A2, B1, thiab B2.
Kev tiv thaiv tau muab
-
✅ Kev Tiv Thaiv Cov Zej Zog
-
✅ Cov Khoom Tiv Thaiv Cov Khoom Tiv Thaiv
-
Kev tiv thaiv ib puag ncig
Nws ua haujlwm li cas
-
Muab cov tshuaj yaj phom Laminar hauv Hepa-lim dhau qhov chaw ua haujlwm.
-
Huab cua sab sab yog kuj hepa-lim ua ntej recirculation lossis tawm.
Cov Hom Kev Kawm Hoob II BSCS
| Ntaus | Airflow Cov yam ntxwv | Cov Ntawv Thov |
| Ntaus A1 | Recirculates 70% ntawm huab cua, 30% sab sab los ntawm HEPA lim | Cov tshuaj tsis muaj tshuaj lom, cov kev tshawb fawb microbiological |
| Ntaus A2 | Ntau dua inflow velocity tshaj A1, 30% sab sab |
Kev Nyab Xeeb Kev Nyab Xeeb Ntawm Cov Tshuaj Muaj Zog Muaj Zog |
| Hom B1 | 70% sab sab, 30% recirculated | Kev tiv thaiv kab mob nruab nrab, microbiology |
| Hom B2 |
100% sab sab rau sab nraud |
Cov tshuaj lom cov tshuaj lom, muaj kev pheej hmoo siab pathogens |
3. Chav Kawm III Kev Ruaj Ntseg Kev Ruaj Ntseg
Kev tiv thaiv tau muab
-
✅ Qib Siab Tshaj Plaws Ntawm Kev Tiv Thaiv (cov neeg ua haujlwm, khoom lag luam, thiab ib puag ncig)
Nws ua haujlwm li cas
-
Tag nrho cov khoom ntim, roj-nruj rau cov hnab looj tes rau cov khoom siv.
-
Muab ob npaug hepa pom thiab / lossis tso pa los ntawm kev ua kom haum.
-
Muab cov khoom ntim siab tshaj plaws rau cov neeg sawv cev muaj kev phom sij ntau tshaj plaws (Biosafety Qib 4).
Cov Ntawv Thov
-
Tuav cov neeg sawv cev muaj txiaj ntsig heev (piv txwv li, Ebola, Sars-Cove, Bacillus Anthracis).
-
Chaw soj ntsuam cov kev tshawb fawb nrog cov tshuaj lom neeg lom neeg lom neeg lossis kev tsim hluav taws xob.
