Uphando lweNgozi yokuValelwa ngaphandle/yokuThengisa
Ukutshixa/ukuthegayayiyenye yeemfuno zokuqala ezamiselwa yi-OSHA, ukususela ngo-1990.ukutshixa/ukuthegaummiselo waqala ukusebenza ngo-1990, kunye nenxalenye ye-Subpart S.Ukutshixa/ukuthegauqeqesho luqhutywa ngokungakhathali kuzo zonke iziko eMelika. Sonke kweli candelo siqeqeshwe ngokuphindaphindiweyo malungaukutshixa/ukuthega. Ukutshixa/ukuthegaIhlala ingumxholo weentlanganiso zangasemva kunye neentlanganiso zokhuseleko. Mhlawumbi yindalo yomntu ukuva into rhoqo kwaye ivela kwimithombo emininzi kangangokuba ngamanye amaxesha siya kwi-autopilot. Endaweni yokwenza ngabom iinkqubo, kwanabona babalaseleyo kuthi basenokungayichaphazeli ngamandla njengoko kufanele. Olu phononongo lokwenyani lulandelayo lubonisa le ngongoma.
Le projekthi yayibandakanya umsebenzi wokulungisa owawusenziwa ngabathengisi abaninzi kwindawo yenkampani eMidwest (indawo yokwamkela iindwendwe). Lo msebenzi wawubandakanya iswitshi ye-medium-voltage kwisakhiwo kunye ne-substation yangaphandle. Iswitshi yayiyeyoyilo oluqhelekileyo lwentsimbi, oluyi-drawout, oluyi-vacuum interrupter kwaye yayikwimeko entle kakhulu. Iswitshi yayiphawulwe ngomgca omnye ngaphambili kwigiya.
Umsebenzi obandakanyeka kwesi siganeko wabelwa ukuba acoce ii-switchgear kunye neebhotile ze-vacuum kwicandelo lezixhobo ezazitshixelwe ngokufanelekileyo, zabekwa uphawu, zavavanywa, zaza zabekwa phantsi komhlaba. Umsebenzi kule candelo le-switchgear ubuqhubeka iintsuku ezimbalwa. Omnye wabakhi bekontraka ucele umsebenzi ukuba acoce aze avavanye i-circuit breaker cell eyayingekho kuluhlu lokuqala lwezixhobo eziza kugcinwa. Inkampani eyayiphethe izixhobo ivumile ukongezwa kwale circuit breaker cell kuluhlu. I-circuit breaker cell yayiye-bus tie breaker eyayingasebenzi ngokuhlwa kwangaphambili kodwa yabuyiselwa kwinkonzo.
