Ukusetshenziswa kweukukhiya ngaphandle kwe-circuit breaker, obeye aziwe njengoizikhiye ze-loto breaker, kuyingxenye ebalulekile yokuqinisekisa ukuphepha kwabasebenzi nokuvimbela izingozi zikagesi endaweni yokusebenza.Ithegi yokukhiya ngaphandle (i-LOTO)Izinqubo ziqashelwa kabanzi njengendlela ephumelelayo yokuvikela abasebenzi emithonjeni yamandla eyingozi, futhi ukusebenzisa ama-breaker lockouts kuyisici esibalulekile sale nqubo.
Ukukhiywa kwe-circuit breakerzenzelwe ukuvimbela ngokomzimba ukusebenza ngengozi noma okungagunyaziwe kwamasekethe noma imishini kagesi. Ziza ngemiklamo nezitayela ezahlukene ukuze zilingane nezinhlobo ezahlukene zama-circuit breaker, okwenza zibe nezimo ezihlukahlukene futhi zivumelane nezimo ukuze zisetshenziswe ezindaweni eziningi zezimboni. Lawa madivayisi abalulekile ekusebenziseni izinqubo ze-LOTO, njengoba enikeza indlela ebonakalayo nephephile yokuhlukanisa imithombo yamandla nokuxwayisa abanye ngomsebenzi oqhubekayo wokulungisa noma wokulungisa.
Enye yezinjongo eziyinhloko zokusebenzisaukukhiya ngaphandle kwe-circuit breakerukuqinisekisa ukuthi imishini kagesi ayisebenzi kahle ngaphambi kokuba kwenziwe noma iyiphi isevisi noma ukulungiswa. Ngokunamathisela idivayisi yokukhiya ku-breaker, imishini ihlukaniswa ngempumelelo nomthombo wayo wamandla, futhi amathuba okusebenza ngengozi ayasuswa. Lokhu kuvumela abasebenzi ukuthi benze imisebenzi yabo ngaphandle kwengozi yokuchayeka kumaza kagesi aphilayo, okunciphisa kakhulu amathuba ezingozi nokulimala kukagesi.
Ngaphezu kwalokho, ukusetshenziswa kweukukhiya ngaphandle kwe-breakerfuthi kudlala indima ebalulekile ekuhambisaneni nemithethonqubo nezindinganiso zokuphepha. Izinhlangano eziningi ezilawulayo, njenge-OSHA e-United States, zidinga abaqashi ukuthi basebenzise izinqubo ze-LOTO ukuvikela abasebenzi babo emithonjeni yamandla eyingozi. Ukwehluleka ukulandela le mithethonqubo kungabangela izinhlawulo futhi, okubaluleke kakhulu, ingozi yezingozi ezinkulu. Ngakho-ke, ukusebenzisaukukhiya ngaphandle kwe-circuit breakerakuyona nje indlela engcono kakhulu yokusebenza, kodwa futhi iyimfuneko esemthethweni ezindaweni eziningi zokusebenza.
Ngaphezu kwalokho, ukufakwa kweukukhiya ngaphandle kwe-breakerIzinqubo ze-LOTO zikhuthaza isiko lokuphepha kanye nomthwalo wemfanelo ngaphakathi kwenhlangano. Lapho abasebenzi bebona ukuthi kuthathwa izinyathelo zokuphepha ezidingekayo, njengokusebenzisa amadivayisi okukhiya, ukuze bavikeleke ekulimaleni okungenzeka, kuqinisa umyalezo wokuthi inhlalakahle yabo iyaziswa. Lokhu kungaholela ekuqwashisweni okukhulu kwezinqubo zokuphepha kanye nendlela ewusizo yokuvimbela izingozi emsebenzini.
Kubalulekile ukuqaphela ukuthi ukuqeqeshwa kanye nemfundo efanele ngokusetshenziswa kweukukhiya ngaphandle kwe-circuit breakerzibalulekile ekusetshenzisweni kwazo ngempumelelo. Abasebenzi kufanele bajwayelane nezinhlobo ezahlukene zamadivayisi okukhiya futhi baqonde ukuthi bangawasebenzisa kanjani ngendlela efanele kuma-circuit breaker ahlukahlukene. Ngaphezu kwalokho, kufanele kusungulwe izinqubo ezicacile nezijwayelekile zokukhiya ngaphandle futhi zidluliselwe kubo bonke abasebenzi ababandakanyeka emisebenzini yokulungisa noma yokulungisa.
Ekuphetheni, ukusetshenziswa kweukukhiya ngaphandle kwe-circuit breakerkuyisici esibalulekile ekuqinisekiseni ukuphepha kwabasebenzi kanye nokuvimbela izingozi zikagesi endaweni yokusebenza. Ngokufaka la madivayisi ezinqubweni ze-LOTO, abaqashi bangahlukanisa ngempumelelo imithombo yamandla kagesi futhi bavikele abasebenzi ezingozini ezingaba khona. Ngaphezu kwalokho, ukusebenzisaukukhiya ngaphandle kwe-breakerikhombisa ukuzibophezela ekulandeleni imithetho yokuphepha futhi ikhuthaza isiko lokuphepha ngaphakathi kwenhlangano. Ukutshala imali ekuqeqeshweni okufanele nasekusetshenzisweni kokukhiywa kwe-circuit breaker kuyindlela yokuqapha enganciphisa kakhulu ingozi yezehlakalo zikagesi futhi ifake isandla endaweni yokusebenza ephephile.
