Ngowama-2020, kwabakho ingozi yonyango lobushushu eMelika, eyabangela ukufa kwabasebenzi ababini. Isizathu yayikukuba iinkqubo zokhuseleko zeLock Out Tag Out (LOTO) kunye neRestricted Space Code azizange zilandelwe.
Le ngozi isixelela ukuba unyango lobushushu lushishino oluyingozi kakhulu, unyango lobushushu alunakwahlulwa kumanzi, igesi, umbane, kunye nezinye izinto eziyingozi zikho kuyo yonke indawo. Ezinye izixhobo ezingasebenzi kakuhle, ukungakhathali, njalo njalo kunokukhokelela kwingozi ebulalayo. Njengoko ukhuseleko lokusingqongileyo kunye neemfuno zomgangatho zisiya ziqina ngakumbi, amashishini amaninzi athenga kwaye asebenzise izithando zomoya zokwenyani, ezibandakanya ukhuseleko lwezithando zomoya kunye nokhuseleko lwegesi engasebenziyo. Le ngozi isibuyisela kwelinye ityala. Ingozi yenzeke ngo-9:30 kusasa ngoMeyi 17, 2001, xa umsebenzi wokulungisa wayesebenza kumgca we-hydraulic kwi-vacuum furnace. Isithando sivulekile ecaleni kwaye sinetanki yokucima enobubanzi obuziimitha ezi-6 kunye nobunzulu obuziimitha ezili-9. Nje ukuba into yokusebenza ibekwe kwilifti yetanki yokucima, isithando sigcwaliswa ngegesi engasebenziyo okanye i-nitrogen endaweni ye-vacuum. Ukuze kulungiswe umgca we-hydraulic, itanki yeoyile yakhutshwa amanzi kwiintsuku ezintathu ezidlulileyo kwaye imoto yafakwa ezantsi kwetanki yokucima. Umlungisi wawela kwitanki engenanto emsebenzini waza umphathi wakhe weva ikhwelo loncedo waza wakhwela esitovini ukuze azame ukumnceda. Oogxa bakhe abavileyo ikhwelo loncedo bafika kwindawo yesiganeko bafumana umntu olungisayo elele kwilifti nomphathi elele ecaleni kwakhe. Ngeli xesha, iphaneli yokulawula isithando iyavulwa kwaye iiswitshi ze-argon kunye ne-nitrogen ziyavulwa. Ukukhutshwa kwegesi kudla ngokulawulwa yivalvu ye-solenoid ngexesha lenkqubo yonyango lobushushu. Akucacanga ukuba kutheni iqalile okanye luhlobo luni lwegesi olwalupompelwa esitovini. Amangqina kamva athi iswitshi kwikhabhinethi yokulawula yombane yayikhomba kwigesi ye-argon. Abasebenzi bokulungisa kunye nabaphathi babenganxibanga helmethi okanye iintambo zokhuseleko, kwaye ngexesha isebe lomlilo lifika kade kakhulu ukuba libayise esibhedlele, ingxelo yokuhlolwa kwesidumbu yathi unobangela wokufa yayikukufunxa umoya.
ILoto, ebhalwe ngokuthi lockout-tagout. I-OSHA yindlela ehambelana ne-OSHA yokuthintela ukwenzakala komntu ngokwahlula okanye ukutshixa imithombo ethile yamandla eyingozi. Isetyenziswe kakhulu kwihlabathi liphela, kwaye ngoku ivele ngexesha elifanelekileyo eTshayina. Kukwakho neenkcazo ezifanelekileyo kuMthetho weMveliso yoKhuseleko. Kukwakho nemigaqo ethile kumgangatho welizwe kuphela onyanzelekileyo weshishini lonyango lobushushu i-GB 15735 2012, iiMfuno zoKhuseleko noCoceko lweNkqubo yoMveliso woNyango loBushushu beMetal. Injongo yayo kukukhusela abasebenzi ekonakaleni kwamandla oomatshini, kubandakanya wonke umsebenzi ofuna ukunxibelelana okanye ukusebenza kufutshane nomatshini okanye izixhobo ezinamandla okanye ezigciniweyo. Indlela ethile kukuvala umbane xa ufaka izixhobo zokucoca \ ukulungiswa \ ukuhlolwa \ kunye nokubonisa ukuba umsebenzi wolondolozo wenziwa ngethegi xa isitshixo singafumaneki, kunye nokuzama emva kokwenza umsebenzi ongasentla.
