Likamore tsa bohloeki ke sehlopha sa meaho e khethehileng e nang le litlhoko tse khethehileng bakeng sa meaho, tlhahlobo ea tikoloho, bokhoni ba basebetsi le bohloeki. Mongoli: Dr. Patricia Sitek, mong'a CRK
Boteng bo ntseng bo hola ba tikoloho e laoloang libakeng tsohle tsa indasteri bo baka mathata a macha bakeng sa basebetsi ba tlhahiso mme ka hona litebello tsa botsamaisi ho kenya tšebetsong litekanyetso tse ncha.
Lintlha tse fapaneng li bontša hore ho feta 80% ea liketsahalo tsa likokoana-hloko le ho feta ha lerole ho bakoa ke boteng le mesebetsi ea basebetsi ka likamoreng tse hloekileng. Ha e le hantle, ho kenella, ho nkela sebaka le ho sebetsana le lisebelisoa tse tala le lisebelisoa ho ka fella ka ho lokolloa ha likaroloana tse ngata, ho fella ka ho fetisoa ha likokoana-hloko ho tloha holim'a letlalo le lisebelisoa ho ea tikolohong. Ntle le moo, lisebelisoa tse kang lisebelisoa, lihlahisoa tsa ho hloekisa le lisebelisoa tsa ho paka le tsona li na le tšusumetso e kholo ts'ebetsong ea phaposi ea bohloeki.
Kaha basebetsi ke bona mohloli o moholo oa tšilafalo ka likamoreng tse hloekileng, ho bohlokoa ho botsa hore na ho ka fokotsoa joang ho ata ha likaroloana tse phelang le tse sa pheleng ho fihlela litlhoko tsa ISO 14644 nakong ea ha basebetsi ba kena ka phaposing e hloekileng.
Sebelisa liaparo tse loketseng ho thibela ho ata ha likaroloana le likokoana-hloko tse tsoang holim'a 'mele oa basebetsi ho ea sebakeng se potolohileng mosebetsi.
Ntho ea bohlokoa ka ho fetisisa ea ho thibela ho ata ha tšilafalo ka likamoreng tse hloekileng ke khetho ea liaparo tse hloekileng tse loketseng boemo ba bohloeki. Khatisong ena re tla shebana haholo le liaparo tse ka sebelisoang hape tse fuoeng litekanyetso tsa ISO 8/D le ISO 7/C, tse hlalosang litlhoko tsa thepa, phefumoloho e holim'a metsi le moralo o ikhethileng.
Leha ho le joalo, pele re sheba litlhoko tsa liaparo tse hloekileng ka kamoreng, re tla tšohla ka bokhutšoanyane litlhoko tsa mantlha tsa basebetsi ba ISO8/D le ISO7/C.
Ntlha ea pele, ho thibela ka katleho ho ata ha tšilafalo ka kamoreng e hloekileng, hoa hlokahala ho hlahisa le ho kenya ts'ebetsong ka kamoreng e 'ngoe le e' ngoe e hloekileng SOP e qaqileng (Standard Operating Procedure) e hlalosang melao-motheo ea ts'ebetso ea kamore ea ho hloekisa mokhatlong. Mekhoa e joalo e tlameha ho ngoloa, ho kengoa ts'ebetsong, ho utloisisoa le ho lateloa ka puo ea tlhaho ea mosebedisi. Ntho e 'ngoe ea bohlokoa boitokisetsong ke koetliso e nepahetseng ea basebetsi ba ikarabellang bakeng sa ho sebetsa sebakeng se laoloang, hammoho le tlhokahalo ea ho etsa litlhahlobo tse nepahetseng tsa bongaka ho ela hloko likotsi tse khetholloang mosebetsing. Ho hlahloba ka boomo matsoho a basebetsi bakeng sa bohloeki, tlhahlobo ea mafu a tšoaetsanoang, esita le ho hlahlojoa meno kamehla ke tse ling tsa “monate” o letetseng batho ba sa tsoa fihla phaposing e hloekileng.
Ho kena ka phaposing e hlwekileng ke ka mochini o notlelang moea, o etselitsoeng le ho hlomelloa ho thibela tšilafalo, haholo-holo tseleng ea ho kena. Ho ipapisitsoe le mofuta oa tlhahiso, re arola li-airlock ho latela likhato tse ntseng li eketseha tsa bohloeki kapa re eketsa li-airlock tsa shaoara ho likamore tse hloekileng.
Leha ISO 14644 e na le litlhoko tse iketlileng tsa maemo a bohloeki a ISO 8 le ISO 7, boemo ba taolo ea tšilafalo bo ntse bo phahame. Sena se bakoa ke hore meeli ea taolo ea lintho tse silafatsang le likokoana-hloko e phahame hoo ho leng bonolo ho fana ka maikutlo a hore re lula re shebile tšilafalo. Ke kahoo ho khetha liaparo tse nepahetseng bakeng sa mosebetsi e le karolo ea bohlokoa ea moralo oa ts'ilafalo, ho kopana le litebello tsa matšeliso feela, empa hape le moralo, litebello tsa thepa le phefumoloho.
Tšebeliso ea liaparo tse sireletsang e ka thibela ho ata ha likaroloana le likokoana-hloko ho tloha holim'a 'mele ea basebetsi ho ea sebakeng se potolohileng mosebetsi. Lintho tse tloaelehileng tse sebelisoang ho etsa liaparo tse hloekileng ke polyester. Sena se bakoa ke taba ea hore boitsebiso boo bo na le lerōle le leholo haholo 'me ka nako e ts'oanang le phefumoloha ka ho feletseng. Ho bohlokoa ho hlokomela hore polyester ke ntho e tsebahalang e nang le boemo bo phahameng ka ho fetisisa ba bohloeki ba ISO, joalo ka ha ho hlokoa ke protocol ea CSM (Cleanroom Suitable Materials) ea Fraunhofer Institute.
Carbon fiber e sebelisoa e le tlatsetso tlhahisong ea liaparo tse hloekileng tsa polyester ho fana ka thepa e eketsehileng ea antistatic. Hangata chelete ea bona ha e fete 1% ea boima bohle ba thepa.
Ho khahlisang, le ha ho khetha 'mala oa liaparo o ipapisitse le bohloeki ho kanna ha se be le phello e tobileng tlhokomelong ea tšilafalo, ho ka ntlafatsa boitšoaro ba mosebetsi le ho beha leihlo tšebetso ea basebetsi sebakeng se hloekileng.
Ho latela ISO 14644-5: 2016, liaparo tsa kamore e hloekileng ha lia tlameha ho boloka likaroloana tsa 'mele ho tsoa ho basebetsi feela, empa ho bohlokoa joalo, li phefumolohe, li phutholohe ebile li hana ho arohana.
ISO 14644 Karolo ea 5 (Sehlomathiso B) e fana ka tataiso e nepahetseng mabapi le ts'ebetso, khetho, thepa ea thepa, ho lekana le ho qeta, boiketlo ba mocheso, mekhoa ea ho hlatsoa le ho omisa, le litlhoko tsa polokelo ea liaparo.
Khatisong ena, re tla u tsebisa ka mefuta e atileng haholo ea liaparo tsa phaposi e hloekileng tse fihlelang litlhoko tsa ISO 14644-5.
Ho bohlokoa ho ela hloko hore liaparo tsa ISO 8 (tseo hangata li bitsoang “pajama”) li tlameha ho etsoa ka polyester e kentsoeng ka carbon fiber, joalo ka sutu kapa seaparo. Li-caps tse sebelisetsoang ho sireletsa hlooho li ka 'na tsa lahleha, empa ts'ebetso ea tsona e atisa ho fokotseha ka lebaka la ho ba le monyetla oa ho senyeha ha mochine. Joale u lokela ho nahana ka sekwahelo se ka sebelisoang hape.
Karolo ea bohlokoa ea liaparo ke lieta, tseo, joalo ka liaparo, li tlamehang ho etsoa ka thepa e hanyetsanang le mechine le e hanyetsanang le ho lokolloa ha litšila. Ka tloaelo rabara kapa thepa e tšoanang e fihlela litlhoko tsa ISO 14644.
Ho sa tsotellehe boemo leha e le bofe, haeba tlhahlobo ea kotsi e bontša hore qetellong ea mokhoa oa ho apara, li-gloves tse sireletsang li apesoa ho fokotsa ho ata ha tšilafalo ho tloha 'meleng oa mosebeletsi ho ea sebakeng sa mosebetsi.
Ka mor'a ho sebelisoa, liaparo tse ka sebelisoang hape li romeloa setsing se hloekileng moo li hlatsuoang le ho omisoa tlas'a maemo a ISO 5 Class.
Kaha litlelase tsa ISO 8 le ISO 7 ha li hloke hore liaparo li hlahisoe ka mor'a ho hloekisoa, liaparo lia phutheloa ebe li romeloa ho mosebelisi hang ka mor'a ho omisoa.
Liaparo tse lahliloeng ha li hloke ho hlatsuoa le ho omisoa, kahoo hoa hlokahala ho li sebetsana le ho theha leano la ho lahla litšila ka har'a mokhatlo.
Liaparo tse ka sebelisoang hape li ka sebelisoa ka matsatsi a 1-5, ho itšetlehile ka se hlahisoang morerong oa taolo ea tšilafalo ka mor'a tlhahlobo ea kotsi. Ke habohlokoa ho hopola hore u se ke ua feta nako e telele eo liaparo li ka sebelisoang ka mokhoa o sireletsehileng, haholo-holo libakeng tsa tlhahiso moo ho hlokahalang taolo ea tšilafalo ea likokoana-hloko.
Liaparo tse khethiloeng ka nepo tse kopanang le litekanyetso tsa ISO 8 le ISO 7 li ka thibela phetiso ea litšila tsa mochini le likokoana-hloko. Leha ho le joalo, sena se hloka hore ho buuoe ka litlhoko tsa ISO 14644, ho etsa tlhahlobo ea kotsi ea sebaka sa tlhahiso, ho theha leano la taolo ea tšilafalo le ho kenya ts'ebetsong sistimi ka koetliso e nepahetseng ea basebetsi.
Esita le thepa e ntle ka ho fetisisa le thekenoloji e ntle ka ho fetisisa e ke ke ea sebetsa ka ho feletseng ntle le haeba mokhatlo o e-na le mekhoa ea koetliso ea ka hare le ea ka ntle ho netefatsa hore boemo bo loketseng ba tlhokomeliso le boikarabelo bo ntlafatsoa ka ho khomarela moralo oa taolo ea tšilafalo.
