Emkhakheni wokuphepha kwezimboni,I-LOTO (Ukukhiya/Ukuthega)kuyisinyathelo esibalulekile sokuphepha ukuvimbela izingozi ezibangelwa ukuqala kwemishini engalindelekile. Isebenza njengomugqa wokugcina wokuzivikela wokuvikela izimpilo zabasebenzi. Njengo "mlindi wesango" ongokoqobo walo mugqa wokuzivikela - izingidi zokuphepha zezimboni - ukukhetha izinto zomzimba wokukhiya akuyona into encane. Kunquma ngqo ukuthi ingidi ingahlala endaweni yayo ezindaweni ezinzima njengomswakama, ukugqwala, kanye ne-voltage ephezulu, kufinyelele ngempela "kukhiyiwe = kuphephile". Izinto zomzimba wokukhiya azinqumi nje kuphela ukuqina kwengidi ezindaweni ezithile kodwa futhi zithinta umphumela wayo wokuxwayisa, ukusebenza kokuvikela ukuphepha, kanye nokulula kokusebenza.
Ingabe izinto zokwakha umzimba wokukhiya ziyisisekelo sezikhiye zokuphepha zezimboni? Umzimba wokukhiya uyingxenye eyinhloko ethwala amandla angaphandle futhi imelana nokuguguleka kwemvelo. Izinto zokwakha eziphansi zingabangela ukuthi ikhiye igqwale, iphuke, futhi ilahlekelwe ukuvikela, okwenza inqubo yokuphepha ingasebenzi. Izinto zokwakha ezinhle kakhulu kumele zihlangabezane nezindinganiso ezine ngasikhathi sinye: amandla aphezulu, ukumelana kwemvelo, ukuvikela, kanye nokuqina.
Ukuhlaziywa okugcwele kwezinto eziyinhloko zokukhiya ukuphepha kwezimboni:1. Izingidi zensimbi ezivamile:Njengezikhiye zethusi zokulingisa, izikhiye zensimbi engagqwali zokulingisa, izikhiye zensimbi, ezifanele izindawo ezivamile zezimboni ngaphandle kwezidingo ezithile. Inzuzo intengo ephansi, kodwa nokubi nakho kuyabonakala. Inqubo eyisisekelo yokumboza ubuso yalezi zikhiye ivame ukugqwala ngemva kokuguga futhi ayilula kakhulu ukuyiphatha.
2. Izingidi zepulasitiki zobunjiniyela:Umqaphi wokuphepha kokuvikela ukushisa.
Lolu hlobo lokukhiya kwepulasitiki lunezici zokuvikela ukushisa, ukulwa nogesi, ukumelana nokugqwala, kanye nokuvikela ukuqhuma. Kuyimfuneko ebalulekile yokugcinwa kukagesi kanye nezinhlelo zamandla. Lokhu okubalulekile kwakhiwe ngokuqinisa isakhiwo, ukugcina ukusebenza kokuvikela ukushisa okuphezulu ngenkathi kuthuthukiswa ukumelana nomthelela, ukumelana nokugqwala, kanye nokumelana nokukhathala, okukwazi ukubhekana nezimo zezimboni ezinzima; ngesikhathi esifanayo, umjikelezo wokwenza ngokwezifiso umfushane futhi ulula, okwenza kube lula ukuphathwa enkambisweni ye-LOTO (Lockout/Tagout).
3. Izikhiye ze-aluminium alloy:Ilula futhi inokumelana okuhle nokugqwala. Izingidi ze-aluminium zilula, kulula ukuzithwala nokuziphatha, zifanele izimo zezimboni ezizwela isisindo.
4. Izingidi zensimbi engagqwali:Ingcono kunezinye izingidi zezinto ezibonakalayo ngokwamandla nokumelana nokugqwala. Ububi ukuthi izindleko zokwenza ngokwezifiso ziphezulu, umjikelezo wokwenza ngokwezifiso mude, ingidi inzima, futhi akulula ukuthwala izingidi eziningi.
Kungakhathaliseki ukuthi iyini impahla, izingidi zokuphepha kumele zihlangabezane nalezi zindinganiso ezilandelayo eziyinhloko:
1. Ukhiye oyingqayizivele noma ongashintshisani:Ingidi ngayinye noma uchungechunge lwayo kufanele ibe nesihluthulelo noma inhlanganisela ehlukile ukuqinisekisa ukuthi umuntu oyikhiyayo kuphela ongayivula.
2. Ingenziwa ngezifiso ngomklamo ojwayelekile:Kufanele kube lula ukulengisa amathegi esixwayiso futhi kube nemibala evelele kanye nezimpawu (ngokuvamile ezifakwa imibala ngokomnyango, uhlobo lomsebenzi, noma uhlobo lwamandla).
3. Ukuthobela imithetho:Kuhambisana nezindinganiso ze-“Locking/Labeling for Hazard Energy Control Methods in Mechanical Safety” ze-GB/T 33579-2017.
