Ngo-2020, kwaba nengozi yokwelapha ukushisa e-United States, eyaholela ekufeni kwezisebenzi ezimbili.Isizathu kwakuwukuthi izinqubo zokuphepha ze-Lock Out Tag Out (LOTO) kanye Nekhodi Yesikhala Esikhawulelwe azizange zilandelwe.
Le ngozi isitshela ukuthi ukwelashwa kokushisa kuyimboni eyingozi kakhulu, ukwelashwa kokushisa akukwazi ukuhlukaniswa namanzi, igesi, ugesi, nezinye izici eziyingozi zikhona yonke indawo.Okunye ukusetshenziswa kabi kwemishini, ukunganaki, nokunye kungaholela engozini ebulalayo.Njengoba ukuvikelwa kwemvelo kanye nezidingo zekhwalithi ziba namandla kakhulu, amabhizinisi aya ngokuya athenga futhi asebenzise iziko langempela lokucisha umoya, okubandakanya ukuphepha kweziko le-vacuum nokuphepha kwegesi engasebenzi.Le ngozi isibuyisela kwelinye icala.Ingozi yenzeke ngo-9:30 ekuseni ngoMeyi 17, 2001, ngesikhathi umsebenzi wokulungisa esebenza kulayini we-hydraulic esithandweni somlilo.Isithando somlilo sivulekele eceleni futhi sinethangi lokucisha elingamafidi angu-6 ububanzi namafidi angu-9 ukushona.Uma ucezu lokusebenza selubekwe endaweni yokuphakamisa ithangi lokucisha, isithando somlilo sigcwaliswa ngegesi engasebenzi noma i-nitrogen esikhundleni se-vacuum.Ukuze kulungiswe ulayini we-hydraulic, ithangi likawoyela lakhishwa ezinsukwini ezintathu ezedlule futhi injini yafakwa ngaphansi kwethangi lokucisha.Umlungisi uwele ethangini elingenalutho emsebenzini kwathi umphathi wakhe wezwa ecela usizo wagibela esitofini ezama ukumsiza.Ozakwethu abezwe ucingo becela usizo bafike endaweni yesigameko bathola indoda yesondlo ilele ku-lift nomphathi elele eduze kwakhe.Kuleli qophelo, iphaneli yokulawula isithando somlilo ivuliwe futhi ama-argon ne-nitrogen switch avuliwe.Ukukhishwa kwegesi kuvame kulawulwa i-valve ye-solenoid phakathi nenqubo yokwelapha ukushisa.Bekungakacaci ukuthi iqaleleni nokuthi hlobo luni lwegesi ebifakwa esithandweni.Ofakazi bakamuva bathi ukushintshwa kwekhabhinethi yokulawula ugesi kukhomba i-argon gas.Izisebenzi zesondlo kanye nabaphathi bebengagqokile izigqoko zokuzivikela noma izintambo zokuvikela, kanti ngesikhathi abezicishamlilo befika sekwephuze kakhulu ukubayisa esibhedlela, umbiko wokuhlolwa kwesidumbu wathi imbangela yokufa kwaba wukuphelelwa umoya.
I-Loto, okubhalwe ukuthi lockout-tagout.I-OSHA iyindlela ethobela i-OSHA yokuvimbela ukulimala komuntu siqu ngokuhlukanisa noma ukukhiya imithombo ethile eyingozi yamandla.Isetshenziswe kabanzi emhlabeni, futhi manje isivele ngesikhathi esifanele eChina.Kukhona nezincazelo ezifanele kuMthetho Wokukhiqiza Ukuphepha.Kukhona nezinhlinzeko eziqondile okuwukuphela kwazo okuyimpoqo kazwelonke yokwelapha ukushisa okujwayelekile okujwayelekile GB 15735 2012, Izimfuneko Zokuphepha Nenhlanzeko Zenqubo Yokukhiqiza Ukwelashwa Kokushisa Kwensimbi.Inhloso yawo ukuvikela abasebenzi emonakalweni wamandla omshini, okubandakanya wonke umsebenzi odinga ukuxhumana noma ukusebenza eduze komshini noma okokusebenza okunamandla noma agciniwe.Indlela ethile ukukhiya amandla lapho ufaka \ ukugcinwa \ ukulungiswa \ ukuhlolwa \ okokusebenza kokuhlanza, nokukhombisa ukuthi umsebenzi wokulungisa wenziwa ngethegi lapho ukukhiya kungatholakali, nokuzama ngemuva kokwenza ngaphezulu komsebenzi.
