Isisebenzi sishintsha i-ballast esibanini sophahla egumbini lokuphumula. Isisebenzi sicisha iswishi yokukhanyisa. Izisebenzi zisebenza zisesitebhisini esingamamitha ayisishiyagalombili bese ziqala ukufaka i-ballast esikhundleni sayo. Lapho isisebenzi siqeda ukuxhuma ugesi, isisebenzi sesibili singena egumbini lokuphumula elimnyama. Njengoba singazi ukuthi kwenziwa umsebenzi wokukhanyisa isibani sophahla, isisebenzi sesibili sashintsha iswishi yokukhanyisa ukuze sikhanyise isibani. Isisebenzi sokuqala sashaywa ugesi kancane, okwasenza sawa esitebhisini. Ngesikhathi sokuwa, isisebenzi selula isandla saso ukuze silungiselele ukufika, okwabangela ukuphuka kwesihlakala. Ukulimala kwadinga ukuhlinzwa, futhi isisebenzi salaliswa esibhedlela ubusuku bonke.
Nakuba isimo sangaphambilini singesokucatshangelwa, inqubo yokukhiya kanye neyokukhipha igesi ichaza ngokunembile umonakalo ongase uvele lapho amandla ayingozi engalawulwa. Amandla ayingozi angaba amandla kagesi, amandla omshini, amandla omoya, amandla amakhemikhali, amandla okushisa noma amanye amandla. Uma engalawulwa kahle noma engakhishwa kahle, angabangela ukuthi imishini isebenze ngokungalindelekile. Kulesi sibonelo, isisebenzi esilungisa ukukhanya kufanele ngabe sihlukanise isekethe ku-circuit breaker futhi siqalise ukusebenza.inqubo yokukhiya kanye nokuthega (i-LOTO)Ukunikezwa kwamandla ku-isolation circuit breaker kungavimbela ukulimala lapho iswishi yokukhanya ivuliwe. Kodwa-ke, ukuvala nje amandla ku-circuit breaker akwanele.
Uma abasebenzi benkonzo yangaphandle behlanganyela emisebenzini engaphakathi kobubanzi kanye nokusetshenziswa kwale nqubo, umqashi osendaweni kanye nomqashi wangaphandle kufanele bazisane ngezinqubo zabo zokukhiya noma zokukhipha. Kubalulekile futhi ukufaka amadivayisi asebenzisa izindlela ezinhle njengezihluthulelo noma izingidi zohlobo lwephasiwedi ukugcina idivayisi yokuhlukanisa amandla isendaweni ephephile futhi ivimbele umshini noma imishini ukuthi ingasebenzi.
Izidingo ze-OSHA ezihlobene nezindinganiso zokulawula amandla ayingozi zingatholakala ku-29.CFR.1910.147. Leli zinga lidinga abaqashi ukuthi bakhe inqubomgomo ye-LOTO ekulungiseni nasekugcinweni kwemishini nemishini, lapho ukuvulwa noma ukuqaliswa kwemishini noma imishini ngengozi, noma ukukhishwa kwamandla agciniwe kungalimaza abasebenzi. Abaqashi kumele bathuthukise izinhlelo futhi basebenzise izinqubo zokuvikela amadivayisi afanele okukhiya noma ukumaka amadivayisi kumadivayisi okuhlukanisa amandla, futhi kungenjalo bakhubaze imishini noma imishini ukuvimbela ukuvulwa, ukuqaliswa, noma ukukhishwa kwamandla ngengozi ukuvimbela ukulimala kwabasebenzi.
Isici esibalulekile sohlelo lwe-LOTO inqubomgomo ebhaliwe. Ngaphezu kwalokho, indinganiso idinga abaqashi ukuthi bathuthukise izinqubo zokulawula amandla, okusho ukuthi izindlela zokuvala nokulungisa imishini kumele zibhalwe phansi. Isibonelo, uma iyunithi yokupholisa umoya idinga ukulungiswa, inqubo yokucima ugesi idinga ukufaka igama/indawo yephaneli ye-circuit breaker kanye nenombolo ye-circuit breaker kuphaneli. Uma uhlelo lunemithombo eminingi yamandla, khona-ke uhlelo lokulawula kumele luchaze indlela yokuhlukanisa yonke imithombo yamandla. Ngaphambi kokuqala umsebenzi emishinini ekhiyiwe noma ebhalwe ohlwini noma imishini, abasebenzi kumele baqinisekise ukuthi imishini ihlukanisiwe futhi icishiwe.
Ezinye izinto ezibalulekile zohlelo lwe-LOTO zifaka phakathi ukuqeqeshwa kwabasebenzi kanye nokuhlolwa njalo kwezinqubo ze-LOTO. Ukuqeqeshwa kuyadingeka ukuze kwabelwe umsebenzi futhi kumele kufake phakathi ukuqeqeshwa ekuboneni imithombo yamandla eyingozi, uhlobo kanye nenani lamandla atholakalayo endaweni yokusebenza, kanye nezindlela nezindlela ezidingekayo zokuhlukanisa amandla nokulawula. Lapho ububanzi bomsebenzi bushintsha, ukufakwa kwemishini emisha noma izinguquko ezinqubweni kungaletha izingozi ezintsha, kudingeka ukuqeqeshwa okwengeziwe.
Ukuhlolwa okwenziwa ngezikhathi ezithile kuwukuhlolwa kwaminyaka yonke kwalezi zinqubo ukuqinisekisa ukunemba kwezinqubo noma ukunquma izinguquko noma ukulungiswa okumele kwenziwe ezinqubweni.
Umnikazi wesiteshi noma umqhubi kumele futhi acabangele izinqubo ze-LOTO zomkontileka. Abakontileka bangaphandle kufanele basebenzise izinqubo zabo ze-LOTO lapho besebenzelana nezinhlelo ezifana nogesi, i-HVAC, izinhlelo zikaphethiloli noma eminye imishini. Noma nini lapho abasebenzi benkonzo yangaphandle behlanganyela emisebenzini ehlanganiswe ububanzi kanye nokusetshenziswa kwendinganiso ye-LOTO, umqashi osendaweni kanye nomqashi wangaphandle kumele bazisane ngezinqubo zabo zokukhiya noma zokukhiya.
