1. Kunzima kakhulu ukuhlanza indawo yokubumbana yokwehlukanisa indawo yokuhlukanisa, opharetha kufanele ahlanze njalo lezi zingxenye futhi ahlomise nge-blade encane nganoma yisiphi isikhathi Amakhono ukulimala . ngesikhathi sokuphamba, i-opharetha ihlukumeza kahle indawo yokubumba yokuhlanganisa ngokusebenzisa i-delifure, kodwa futhi ingakuhlanza isikhunta se-decides e-carsity ngesikhathi se-carsity ngesikhathi senqubo yokujova ukuthuthukisa ikhwalithi ye Umkhiqizo . Kungcono ukuhlanza indawo yokuhlukanisa kabili eqenjini . Vumela abasebenzi bahlakulele umkhuba omuhle .}
2. Ukusetshenziswa kohlelo lokupholisa isikhunta amanzi okubumba, anemiphumela emibi . Izinto zokwakha ngokuvamile zenziwe ngensimbi ekhethekile yokwelashwa . Lapho amazinga okushisa aphezulu aphezulu kakhulu, futhi kuzovela kalula ukuqhekeka ebusweni noma Akukho ngaphezu kokuqhekeka okungu-2000 kokubumba okungama-2000 ukunamathela . Esimweni sokusebenzisa amanzi okupholisa isikhunta, ukusetshenziswa kwe-ejenti yokukhishwa kungancishiswa kakhulu, ukuze usebenze imodeli yokukhishwa, ukunciphisa ukuvela komkhiqizo, ukunciphisa ukunamathela I-Aluminium, futhi yehlisa ukusetshenziswa kwe-ejenti yokukhishwa . Ibuye inciphise ukulahleka kwenqama kanye nomnyombo ngenxa yokushisa ngokweqile kokushisa okubumba .
