Ngakwenzekani ukuthi kubulawulekwe ukuvula kwemithombo yezinyawo zokuvula kwezindawo eziphakanyiswa ngokuphelele kwe-GMP ngomso?

Umhlaba wokubulawa: Kungani ukuvulwa kugcina ngomso kuyenza ukuthi kuhlanganise izinkantolo zesi-GMP ezinkulu

I-EU GMP Annex 1 (2022) ne-FDA Guidance ngokuvula ngokuphelele kwezinhlobo zezinyawo

Ukulawulwa kwemvelo emakamelweni ahlanzekile e-GMP akuyona into ongakhetha ukuyenza kodwa kunesidingo ngokomthetho. Ngokwe-EU GMP Annex 1 yakamuva ka-2022, izakhiwo kudingeka zigcine izinhlayiya ezisemkhathini zingenawo amazinga aqinile ngaso sonke isikhathi. Phakathi naleso sikhathi, iziqondiso ze-FDA zithi izinhlelo zokungenisa umoya kufanele zisebenze ubusuku nemini ukuze kungakhuli izinto ezingcolisayo. Kuye kwavela nezinkinga zangempela. Ngonyaka odlule, isixwayiso se-FDA sabonisa ukuthi lapho omunye umenzi wezidakamizwa evala uhlelo lwakhe lwe-HVAC ngobusuku obubodwa, amazinga ezinhlayiya eziphilayo akhuphuka kakhulu kunamazinga amukelekayo ngo-300%. Lokhu kusiletha ku-Air Change Rate noma i-ACR ngamafuphi. Ngisho nalapho kungekho muntu osebenza kulezi zindawo, kudingeka kube nokunyakaza komoya okwanele ukuze kugcinwe izimo ezifanele. Abakhiqizi abaningi bayakuqonda lokhu manje ngemva kokubona ukuthi kwenzekani lapho benciphisa ukugeleza komoya phakathi namahora okuphumula.

Izidingo Zokuzinza ze-ISO 14644-1: Kungani Isilinganiso Sokushintsha Komoya Singeke Sehle Sibe Zero

Ngokwezinga le-ISO 14644-1, ukuzinza kubhekisela ngokuyisisekelo endleleni igumbi elihlanzekile elingabuyela ngayo ezingeni elivamile lekhwalithi yomoya ngemva kokuba okuthile kuphazamise. Futhi qagela ukuthi kwenzekani? Lolu hlelo lonke luxhomeke ngokuphelele ekubeni nomoya omncane ovamile ovundlile ngaso sonke isikhathi. Lapho izakhiwo zivalwa ngokuphelele ubusuku bonke, izinga lokungcola komoya liwela phansi, okuyinto empeleni ephula incazelo yesimiso yezimo "zokuphumula". Izinga licabanga ukuthi kusekhona umoya ohambayo, kodwa hhayi ngamandla aphelele. Ucwaningo lwakamuva olwenziwe kuyi-Journal of Cleanroom Technology ngo-2024 lubonisa ukuthi izinhlayiya ziqala ukuzula futhi ngokushesha, ngokuvamile kungakapheli imizuzu engaba ngu-15 ngemva kokuba umoya usuyekile ukujikeleza. Futhi lapho kungekho ukuhlanjululwa okuqhubekayo, izindawo ezithile zivame ukuba zimbi kakhulu ukuze ama-microbes akhule, ikakhulukazi lapho izindawo zihlala zimanzi noma ziseduze nemishini ekhipha ukushisa.

Imiphumela Yobuciko: Ukuwohloka Komkhiqizo Womoya Nengozi Yokubuyiselwa

Isikhathi Sokungafanele: Ukubhalwa Kwemithambo Yokugcina ACR Nobukhuthaza Kwemithambo Emva Kokukhupha Umsebenzi

Ngomuhla owakhiwe ngokukhupha umsebenzi wokufaka amandla, Isivinini Sokuguqula Amadluli (ACR) siphuma kusodwa ngemizuzu emibili futhi. Ngokwemibhalo yezinkcukacha, amakhaya okuhlanza okuvame ukuba kuyisikhalo se-ISO Class 5 siphuma kusodwa emlandweni wase-Class 8 ngemizuzu eyishumi namashumi ayisithupha ngoba imithambo ethile ekhona emasimini isebenza kahle futhi. Lezi zimithambo ezihlukene phakathi kwe-0.5 kanye ne-5 microns zibuka kabusha emkhathini ngokushesha kakhulu kusukela ku-1,000 imithambo ngumetro wekubili ngomzuzu lapho akukho umsebenzi wokufaka amandla, okuyinto ephindaphinda kuzisa izindlela zokuhlanza zase-ISO 14644-1 zokuhlala kahle. Futhi lokho okubalulekile kakhulu: izinkcukacha ezenziwe ngo-2023 zibonisa ukuthi izinhlobo zezinyawo zokuhlaza ziyafika emazwi amaningi ngemizuzu eyishumi namashumi ayisithupha. Lokhu kubonisa ukuthi izinkinga zokuhlaza azifanele kubhekana ngokuphelele kodwa kubhekana ngokushesha kakhulu lapho izinto zihlala kahle.

Iziqukuthelo Zabantu: Ukuvula Amadola Nokusebenza Okwesikhathi Sokungabi Nabantu

Izakhiwo eziningi zisavuleka ngezikhathi okuthiwa azinabantu ukuze kwenziwe umsebenzi wokuzilungisa, ukuhlola ukuphepha noma ukuphendula ezimweni eziphuthumayo. Lapho lokhu kwenzeka, ukungena ngakunye kuletha izinhlayiya eziphakathi kuka-50.000 no-100.000 ezindaweni ezihlanzekile ezibhekwa njengeziyiGrad A. Yilokho okungenzeka uma abantu abangu-15 bephuma ngendlela evamile.

Ngaphezu kwalokho, ukushisa okusele kwemishini engahlelekile kudala izindlela zokunyakaza komoya ezibuyisela lezi zingcolisi ezindaweni ezibucayi lapho kungafanele zibe khona. Ukugcina uhlobo oluthile lwesilinganiso sokushintsha komoya luqhubeka, ngisho nalapho lungekho ngamandla aphelele, kusadingeka ngokuphelele ukuze kubhekanwe nalezi ziphazamiso ezingavamile kodwa ezingalindelekile ezindaweni ezilawulwayo.

Izindlela Ezisebenzayo: Amasu Okuphehla Umoya Asebenzisa Amandla Ahlakaniphile Agcina Ukuhambisana

Imodi yokunciphisa ukugeleza vs ukuvalwa okuphelele: I-ACR Minimum evunyiwe yezikhathi ezingekho

Ukuvala ngokuphelele ebusuku kuphambene nemithetho eyisisekelo yokulawula ukungcola, nakuba kunezinye izindlela ezingcono. Izindlela zokunciphisa ukugeleza ziye zahlolwa futhi zafakazelwa ukuthi ziyavumelana nezimo futhi ziwusizo ekusindiseni amandla. Ucwaningo olushicilelwe emaphephandabeni kanye nokuhlolwa kwezwe langempela kubonisa ukuthi ukugcina izinga lokuguqulwa komoya eliphakathi kwamaphesenti angu-30 kuya kwangu-50 lapho kungekho muntu eduze kuvimbela izinhlayiya ukuba zingakhuli emoyeni, konke lokhu kuyilapho kugcinwa izindinganiso ezifanele zendawo ehlanzekile. Ngokwesibonelo, esinye isitshalo sokukhiqiza sanciphisa izindleko zaso ze-HVAC ngamaphesenti angu-40 ngonyaka odlule ngokumane sisebenzise uhlelo lwaso ngejubane eliphansi ebusuku, kodwa sasisahlangabezana nezidingo ze-ISO Class 5 ngokwemibiko yaso yokuqinisekisa. Ake sibheke umehluko manje etafuleni elilandelayo.

Ukuvula Kwemithambo Ngokwesifundo Sokunqoba (DCV) Namasensha Owonaqondile Emizini YegMP

Izinhlangano Zokuvula Kwemithambo Ngokwesifundo Sokunqoba (DCV) zihlela ngokushintana ukuvula kwemithambo ngokusebenzisa izindaba zezikhathi zezinsuku, izikhathi zokuphakama kwezinkambu, nezikhathi zokubona ukuthi kunezinto ezibonakalayo. Lokhu kusinika ukunciphisa imali yokuqala ngokuphakama kwe-15–25% ngaphezulu kwezindlela zokuvula kwemithambo ngokuphakama okungashinti—ngaphandle kokukhula ubuchwepheshe bokuhlanza kwamazinyo. Izinhlangano zokuvula kwemithambo ngokwesifundo sokunqoba zihlela ngokuzenzakalelayo:

• Ukuvula kwemithambo ngokushintana ngeminyaka yezindlela zokuguqula (isibonelo: ukulungisa izinkambu noma ukugcina izinto ezingaphansi),
• Ukuqala ukuvula kwemithambo okufanayo ngaphambi kokufika kwabantu,
• Ukudala izirekodi ezinokubonwa ngokuvamile, nezirekodi zezikhathi zokubhalwa ngokuvamile zezinto zokuphatha.

Izinhlangano eziphathelwe ngokuvamile zibonisa ukuthi akukho zinto ezingavamile uma izinhlangano zokuvula kwemithambo ngokwesifundo sokunqoba ziyafakwa ngokufanele nezindlela zokuphatha kwe-EU GMP Annex 1 (2022) zokuphatha ngokuvamile nokuphatha kwezinhloso zokuphatha.

Ukuphatha Ngokwesibonelo: Iziphi Izindaba Zokwesibonelo Zokubonisa Ukuvula Kwemithambo Ngeminyaka Yezinsuku?

Isifundo Sasekhaya Lomthwalo Wokuphatha: Ukunciphisa Imali Yokuqala Ngokuphakama Kwe-40% Ngaphandle Kokukhula Kwenzinto Ezingavamile

Enye inkampani enkulu yezemithi yasungula indlela yokuhlola ukunciphisa izinga lokushintsha komoya ebusuku, igcina umoya uvame ukugeleza cishe ngo-30% lapho kungekho muntu osebenza khona, konke lokhu kuyilapho ihlangabezana namazinga e-ISO 14644-1. Ngemva kokubuka lokhu kusethwa cishe izinyanga ezingu-18 zilandelana, babona izindleko zabo zokushisa nokupholisa zehla ngo-40%, zabasindisa cishe isigamu sesigidi samadola ngonyaka, futhi zazingenazo izinkinga ngokuhambisana nemvelo. Izilinganiso zezinhlayiya zesikhathi sangempela zabonisa ukuthi izinga lothuli lahlala lingaphansi kakhulu kwezimfuneko ze-ISO Class C phakathi naso sonke lesi sikhathi, ngisho nalapho izisebenzi zokuphepha zenza ukuvakasha kwazo noma iminyango ivuleka ngengozi. Lokhu kubonisa ukuthi ukunciphisa umoya ngokucophelela okusekelwe emininingwaneni yangempela kusebenza kangcono kakhulu kunokuvele ukucisha konke ngokuphelele. Lezi zinhlobo zokulungisa okuhlakaniphile zenza izakhiwo zonge imali ngaphandle kokuphazamisa izindinganiso zokulawula ikhwalithi ezidingekayo ekukhiqizeni imithi.

Imibuzo Evame Ukubuzwa

Kungani ukulawula imvelo okuqhubekayo kubalulekile emakamelweni ahlanzekile e-GMP?

Ukukhokha kwezinye izinhlayo zokulawula umoya kuyisisekelo sokugcina ubunzima bezomoya nokubhindela ukungabikho kwezinye izinhlayo, okuhlinzekile ukuthi izindawo ziphathwe ngemithombo yezimboni njenge-Annex 1 yase-EU GMP nezindlela zokusebenza zase-FDA.

Kuzoba kuphi uma isistimu yomoya yendawo esihlanu (HVAC) isetshenziswa ngemuva kwesikhathi eside?

Ukuvalelwa kwe-HVAC ngemuva kwesikhathi eside kungahlela ukuphakama kwezinhlayo, okungahlela ukukhulula imithombo yase-GMP nezinhlayo zase-ISO, ngoba izinhlayo zihlala kusuka emanzini futhi izilwane zomoya zihlanganisa ngaphandle kokukhokha kwezinhlayo.

Ngabe kukho izindlela zokukhokha kwezinhlayo ezinamandla okusebenza okuphathelene nesimboni sase-GMP?

Yebo, izindawo zingasebenzisa izindlela zokukhokha kwezinhlayo ezincane futhi izistimu zokukhokha kwezinhlayo zokufuna (DCV) ukugcina ukuphathelene nesimboni ngaphandle kokugcina amandla. Lezi zindlela zinconywa ukubalansisa ukusebenza ngamandla nokubhindela ukungabikho kwezinhlayo.

Yiziphi izinkinga eziphathelene nokuvalelwa kwezinhlayo zonke?

Ukuvalwa ngokuphelele kokugeleza komoya kubeka izingozi zokungcola, ukuvuselelwa ngokushesha kwezinhlayiya, nokungahambisani nemithetho ye-ISO ne-GMP, okungathinta kakhulu ikhwalithi nokuphepha komkhiqizo.
