Uphenyo Lwengozi Yokukhiya/Yokuthena
Ukukhiya/ukuthegakwakungenye yezimfuneko zokuqala ezabekwa yi-OSHA, kusukela ngo-1990. Ugesiukukhiya/ukuphumaumthethonqubo waqala ukusebenza ngo-1990, kanye nengxenye ye-Subpart S.Ukukhiya/ukuthegaukuqeqeshwa kwenziwa ngokungazelelwe kuzo zonke izikhungo e-United States. Sonke esisensimini siqeqeshwe kaninginingi ku-ukukhiya/ukuphuma. Ukukhiya/ukuthegaNgokuvamile kuyisihloko semihlangano yangemuva kanye nemihlangano yokuphepha. Cishe kuyimvelo yomuntu ukuzwa into kaningi kangaka futhi evela emithonjeni eminingi kangangokuthi ngezinye izikhathi siya ku-autopilot. Esikhundleni sokudlula ezinqubweni ngamabomu, ngisho nabangcono kakhulu kithi bangase bangashayi kanzima njengoba kufanele. Ucwaningo olulandelayo lweqiniso lubonisa leli phuzu.
Lo msebenzi wawuhilela umsebenzi wokulungisa owawusenziwa osonkontileka abaningana endaweni yenkampani eMidwest (indawo yokwamukela). Lo msebenzi wawuhilela iswitchgear ene-voltage ephakathi esakhiweni kanye nesiteshi esincane sangaphandle. Iswitchgear yayiklanywe ngendlela ejwayelekile yensimbi, i-drawout, i-vacuum interrupter futhi yayisesimweni esihle kakhulu. Iswitchgear yayiphawulwe nangomugqa owodwa ngaphambili kwegiya.
Isisebenzi esihilelekile kulesi sigameko sabelwa ukuhlanza ama-switchgear namabhodlela e-vacuum engxenyeni yemishini eyayivalelwe kahle, ivaliwe, ihlolwe, futhi ibekwe phansi. Umsebenzi kule ngxenye ye-switchgear wawuqhubeka izinsuku ezimbalwa. Omunye wabakhi benkontileka ucele isisebenzi ukuthi sihlanze futhi sihlole iseli le-circuit breaker elalingekho ohlwini lokuqala lwemishini okufanele inakekelwe. Inkampani ephethe imishini yamukele ukwengezwa kwaleli seli le-circuit breaker ohlwini. Iseli le-circuit breaker laliyi-bus tie breaker eyayikhishwe amandla kusihlwa ngaphambilini kodwa yabuyiselwa ekusebenzeni.
