Amadivayisi okukhiya ngaphandleziyithuluzi elibalulekile lokuqinisekisa ukuphepha kwabasebenzi lapho benza ukulungiswa noma ukulungiswa kwemishini kagesi. Zivimbela ukusebenza ngengozi kwemishini noma imishini engabangela ukulimala kwabasebenzi. Kunezinhlobo eziningana zamadivayisi okukhiya atholakalayo, ngayinye eyenzelwe izinhlelo ezithile. Kulesi sihloko, sizohlola izinhlobo ezahlukene zamadivayisi okukhiya angaphandle, sigxile ekukhiya kwe-loto kanye namadivayisi okukhiya angaphandle kwama-circuit breaker.
Izikhiye zeLoto, ezaziwa nangokuthiukukhiya ngaphandle/ukukhipha i-tagout, ingenye yezinhlobo ezivame kakhulu zamadivayisi okukhiya ngaphandle. Zisetshenziselwa ukukhiya imithombo yamandla ngokuphephile, njengezinkinobho zikagesi, ama-valve, noma imishini, ukuvimbela ukusebenza ngengozi noma okungagunyaziwe. Lezi zikhiye ziza ngezitayela ezahlukene, kufaka phakathi ama-padlock, izikhiye ezihlanganisiwe, kanye nezikhiye zokhiye, futhi zivame ukwenziwa ngezinto eziqinile njengensimbi noma i-aluminium ukuze zikwazi ukumelana nezimo zezimboni ezinzima.
Uma kukhulunywa ngokuthiamadivayisi okukhiya ngaphandle kwama-circuit breaker, kunezinketho eziningana ezitholakalayo. Uhlobo olulodwa oludumile yi-circuit breaker lockout, eyenzelwe ngqo ukulingana phezu kwe-toggle noma i-switch ye-circuit breaker ukuze ivinjwe ukuthi ingavulwa. Lawa madivayisi okukhiya atholakala ngobukhulu obuhlukahlukene ukuze afake izinhlobo ezahlukene zama-circuit breaker futhi avame ukufakwa i-hasp noma i-clamp ukuze iwaqinise endaweni yawo.
Olunye uhlobo lweidivayisi yokukhiya ngaphandle yama-circuit breakeriyithegi yokukhiya i-circuit breaker. Le divayisi ayivimbeli nje kuphela ngokomzimba i-circuit breaker ukuthi isebenze kodwa futhi inikeza isibonakaliso esibonakalayo sesimo semishini. Ithegi inganamathiselwa kudivayisi yokukhiya ukuze ibonise ulwazi olubalulekile, njengesizathu sokukhiya, igama labasebenzi abagunyaziwe, kanye nosuku nesikhathi sokukhiya.
Ngaphezu kweizikhiye ze-loto kanye namadivayisi okukhiya ngaphandle kwama-circuit breakers, kunezinye izinhlobo zamadivayisi okukhiya aklanyelwe imishini nemishini ethile. Isibonelo, ama-hasps okukhiya asetshenziselwa ukukhiya imithombo yamandla eminingi ngokuphephile ngedivayisi eyodwa, okwenza kube kuhle ezimweni zokukhiya kweqembu. Okwamanje, amadivayisi okukhiya ama-valve ebhola aklanyelwe ukulingana phezu kwesibambo se-valve yebhola ukuvimbela ukuthi ingaphendulwa, futhi amadivayisi okukhiya ikhebula asetshenziselwa ukukhiya imishini emikhulu nengamile ngendlela engavamile.
Uma ukhethaidivayisi yokukhiya ngaphandle, kubalulekile ukucabangela izidingo ezithile zemishini noma imishini evalelwa ngaphandle. Izici ezifana nohlobo lomthombo wamandla, usayizi nesimo semishini, kanye nezimo zemvelo kufanele zicatshangelwe. Ngaphezu kwalokho, kubalulekile ukuqinisekisa ukuthi amadivayisi okuvalela ahambisana nezindinganiso zokuphepha ezifanele kanye nemithethonqubo ukuqinisekisa ukusebenza kwawo ngempumelelo.
Ekuphetheni, izingidi ze-loto kanyeamadivayisi okukhiya ngaphandle kwama-circuit breakerziyizibonelo ezimbili nje zezinhlobo ezahlukene zamadivayisi okukhiya atholakalayo. Ngokukhetha idivayisi yokukhiya efanele yohlelo oluthile, abasebenzi bangazivikela ngempumelelo emithonjeni yamandla eyingozi futhi bavimbele izingozi emsebenzini. Kubalulekile kubaqashi kanye nochwepheshe bezokuphepha ukunikeza ukuqeqeshwa okufanele kanye nesiqondiso ekukhetheni nasekusebenziseni amadivayisi okukhiya angaphandle ukuqinisekisa ukuphepha kwabo bonke abasebenzi ababandakanyeka emisebenzini yokulungisa nokulungisa.
