Isisebenzi sishintsha i-ballast ekukhanyeni kosilingi egunjini lokuphumula.Isisebenzi sivala iswishi yokukhanya.Izisebenzi zisebenza ngeladi elingamamitha ayisishiyagalombili futhi ziqala ukushintsha i-ballast.Lapho umsebenzi eqeda ukuxhuma ugesi, umsebenzi wesibili ungena endaweni yokuphumula emnyama.Njengoba singawazi umsebenzi owenziwa ekukhanyeni ophahleni, isisebenzi sesibili siguqule isibani ukuze sikhanyise.Isisebenzi sokuqala sishayiswe ugesi kancane, okumenze wawa esitebhisini.Ngesikhathi sokuwa, isisebenzi selula isandla saso ukuze silungiselele ukuhlala, okwenza ukuba isihlakala siphuke.Ukulimala kwakudinga ukuhlinzwa, futhi isisebenzi salaliswa esibhedlela ubusuku bonke.
Nakuba isimo sangaphambilini siwukucatshangelwa, inqubo yokuvala ngaphandle ne-tagout ichaza ngokunembile ingozi engaba khona engenzeka uma amandla ayingozi engalawulwa.Amandla ayingozi angaba amandla kagesi, amandla emishini, amandla omoya, amandla amakhemikhali, amandla ashisayo noma amanye amandla.Uma ingalawulwa kahle noma ingakhululwa, ingabangela ukuthi okokusebenza kusebenze kungalindelekile.Kulesi sibonelo, umsebenzi ohlinzeka ukukhanya kufanele ngabe usehlukanise isekethe ku-breaker bese eqalainqubo yokukhiya nokuphuma (LOTO)..Ukunikezwa kwamandla ku-isolation circuit breaker kungavimbela ukulimala lapho iswishi yokukhanya yenziwe yasebenza.Kodwa-ke, ukumane uvale amandla ku-breaker circuit akwanele.
Lapho abasebenzi besevisi bangaphandle benza imisebenzi engaphakathi kobubanzi nasekusetshenzisweni kwaleli zinga, umqashi osendaweni kanye nomqashi wangaphandle bazokwazisana ngezinqubo zabo zokukhiya noma zokumaka ngaphandle.Kuyadingeka futhi ukufaka amadivayisi asebenzisa izindlela ezinhle ezifana nokhiye noma izingidi zohlobo lwephasiwedi ukuze kugcinwe idivayisi yokuhlukanisa amandla isendaweni ephephile futhi kuvinjwe umshini noma okokusebenza ukuthi kunikwe amandla.
Izidingo ze-OSHA ezihlobene namazinga okulawula amandla ayingozi zingatholakala kokuthi 29.CFR.1910.147.Leli zinga lidinga ukuthi abaqashi benze inqubomgomo ye-LOTO ekulungiseni nasekugcinweni kwemishini nezinto zokusebenza, lapho amandla okusebenza ngephutha noma ukuqaliswa kwemishini noma okokusebenza, noma ukukhishwa kwamandla agciniwe kungase kulimaza abasebenzi.Abaqashi kufanele bakhe izinhlelo futhi basebenzise izinqubo ukuze bavikele imishini yokukhiya efanele noma imishini yokumaka emishinini yokuhlukanisa amandla, futhi uma kungenjalo bakhubaze imishini noma okokusebenza ukuze kuvinjwe amandla okukhanyisa ngengozi, ukuqalisa, noma ukukhishwa kwamandla ukuze kuvinjelwe ukulimala kwezisebenzi.
Isici esibalulekile sohlelo lwe-LOTO inqubomgomo ebhaliwe.Ngaphezu kwalokho, izinga lidinga ukuthi abaqashi bathuthukise izinqubo zokulawula amandla, okusho ukuthi izindlela zokuvala nokulungisa imishini kufanele zibhalwe phansi.Isibonelo, uma iyunithi ye-air conditioning idinga ukulungiswa, inqubo yokuvala amandla idinga ukufaka igama/indawo yephaneli ye-circuit breaker kanye nenombolo ye-circuit breaker kuphaneli.Uma uhlelo lunemithombo eminingi yamandla, uhlelo lokulawula kufanele lucacise indlela yokuhlukanisa yonke imithombo yamandla.Ngaphambi kokuqala umsebenzi emishinini ekhiyiwe noma esohlwini noma emishinini, abasebenzi kufanele baqinisekise ukuthi okokusebenza kuhlukanisiwe futhi kucishiwe.
Ezinye izici ezibalulekile zohlelo lweLOTO zihlanganisa ukuqeqeshwa kwabasebenzi kanye nokuhlolwa okuvamile kwezinqubo zeLOTO.Ukuqeqeshwa kuyadingeka ukuze kunikezwe umsebenzi futhi kumele kufake ukuqeqeshwa ekuboneni imithombo yamandla eyingozi, uhlobo kanye nenani lamandla atholakalayo endaweni yokusebenza, nezindlela nezindlela ezidingekayo zokuhlukaniswa nokulawula amandla.Lapho ububanzi bomsebenzi bushintsha, ukufakwa kwemishini emisha noma izinguquko ezinqubweni zingase zilethe izingozi ezintsha, ukuqeqeshwa okwengeziwe kuyadingeka.
Ukuhlolwa ngezikhathi ezithile kuwucwaningo lwaminyaka yonke lwalezi zinqubo ukuze kuqinisekiswe ukunemba kwezinqubo noma ukunquma izinguquko noma izilungiso okufanele zenziwe ezinkambisweni.
Umnikazi wetheminali noma u-opharetha kufanele futhi acabangele izinqubo ze-LOTO zosonkontileka.Osonkontileka bangaphandle kufanele basebenzise izinqubo zabo ze-LOTO lapho besebenza nezinhlelo ezinjengogesi, i-HVAC, amasistimu kaphethiloli noma ezinye izinto zokusebenza.Noma nini lapho abasebenzi benkonzo bangaphandle benza imisebenzi ehambisana nobubanzi kanye nokusetshenziswa kwezinga le-LOTO, umqashi osendaweni kanye nomqashi wangaphandle kufanele bazisane ngezinqubo zabo zokukhiya noma zokumaka ngaphandle.
