Ngokukhula kwemithetho eqinile yokungeniswa kokudla emhlabeni wonke, abathengi baphesheya benza ucwaningo oluqinile lwasefekthri ezingqungqutheleni zokucubungula izinto ezingavuthiwe. Abakhiqizi abaningi bemikhiqizo eqandisiwe{1}}bahlangabezane nezingqinamba ekuhlolweni kwamakhasimende, ikakhulukazi ezibangelwa ukwakheka kwezinto ezingenangqondo. Amakhona afile, ama-weld angalingani, izikhala ezingahlukaniseki kalula zizoqoqwa isithelo, izinsalela zenyama kanye nezinto eziphilayo. Ngaphansi-izimo zokukhiqiza zesikhathi eside, lezi zinsalela zizala amagciwane kanye nesikhunta, okubangela ukweqa amazinga amancane, okuholela ngokuqondile ekuboshweni kwempahla noma ekubuyiselweni ngesikhathi sokuvunyelwa kwempahla.
Imishini yethu yokumisa iqhwa ithatha ukuphepha kokudla njengokuhamba phambili ekwakhiweni. Zonke izakhi ezithintana ngokuqondile nezinto zokusetshenziswa okuhlanganisa amathreyi wezinto ezibonakalayo, udonga lwangaphakathi lwegumbi lokomisa, amafreyimu wenzuzo yempahla enziwe ngensimbi engagqwali engu-304{2}yezinga. Ama-welds angaphakathi acwebezeliswa kahle ngaphandle kwemigodi nezikhala, asusa ama-engeli afile afihliwe. Isakhiwo sisonke silungele ukuqaqa nokuhlanza ngesandla, futhi singafanelana nesistimu yokuhlanza ye-CIP yokuguquguquka okuzenzakalelayo.
Isakhiwo sokuvala umnyango sisebenzisa idizayini emelene-yezinsalela ukuze kuvinjwe izingcezu zezinto ezibonakalayo ukuthi ziboshwe endaweni yokuvala. Isakhiwo sepayipi sigwema ukunqwabelana koketshezi olusele. Konke ukuthuthukiswa kwesakhiwo kuhlose ukunciphisa ukunamathela kwezinsalela. Emabhizinisini akhiqiza izinhlobo eziningi ezifana nezithelo, inyama nokudla okusebenzayo, idizayini yenhlanzeko enengqondo ingavimbela ngempumelelo{4}ukungcola phakathi kwamaqoqo ahlukene nezinto zokusetshenziswa ezihlukile.
Idizayini yokuhlanzeka iletha-izinzuzo ezibanzi zesikhathi eside. Izinkomba ezizinzile zokuhlola ama-microbial zisiza abacubunguli bokudla ukuthi bagcine-ubudlelwano bokubambisana besikhathi eside nemikhiqizo yezitolo ezinkulu zaphesheya kanye nabangenisa kwamanye amazwe. Lapho kuxoxiswana ngama-oda, ukucushwa okujwayelekile kwemishini ehlanzekile kuba inzuzo ebalulekile yesitifiketi. Emafekthri okudla okomisiwe-okukhishelwa ngaphandle{6}}, ukutshala imali ekuthunjweni kwendle{7}}imigqa yokukhiqiza ehambisanayo yokumisa iqhwa{8}}kuyindlela esebenzayo yokugwema ukulahlekelwa okukhulu okubangelwa ukuhlolwa okungafanelekile.
