Isethulo, isiphetho esisodwa esivalekile esiyindilinga noma ishubhu lensimbi engagqwali eliyisicaba lenzwa yezinga lokushisa, elakhelwe ukunikeza ukufundwa okuthembekile nokunembile ezinhlelweni zokusebenza ezimbalwa zezentengiso. Lawa mapayipi angatholakala kukho kokubili okuyisiyingi kanye nokukhetha okuyisicaba ngokuvala okukodwa ukuze enze izilinganiso ezinembile.
Yakhiwe ngekhwalithi ephezulu isiphetho esisodwa esivaliwe esiyindilinga noma ishubhu lensimbi engagqwali eliyisicaba lenzwa yezinga lokushisa elinikeza ukumelana okukhethekile nokugqwala kanye ne-oxidation, iqinisekisa ukusebenza okuhlala njalo ngisho nasezindaweni ezizungezile ezinonya. Iyakwazi futhi ukumelana nezimo eziphakeme, okuyenza ilungele ukusetshenziswa ezinqubweni zokukhiqiza ezibandakanya izinga lokushisa.
Lawa mapayipi enzwa yokushisa anendawo ebushelelezi futhi elinganayo eyenza ukuhlanzeka okusheshayo nokulula. Kuyasiza ukwenza isiqiniseko sokufundwa okunembile futhi kumise ukungcoliswa phakathi kwezinto ezahlukahlukene. Isiphetho esivaliwe sisebenza njengesithiyo, esivimbela noma yiziphi izinto ezingamukelekile ukuthi zingangeni epayipini futhi zibe nomthelela ekunembeni kokufundwa kokushisa.
Izinketho eziyindilinga neziphansi zinikeza ukuguquguquka nenkululeko, okuvumela abasebenzisi ukuthi bathole ukukhetha okungcono kakhulu kuzimfuneko zabo. Ipayipi eliyisicaba lilungele izinhlelo zokusebenza lapho kudingeka khona iphrofayili ephansi; futhi ingafakwa kalula egiyeni ngaphandle kwesidingo sabakaki abahlukile. Ipayipi eliyindilinga ngakolunye uhlangothi lilungele ukusetshenziswa lapho indawo ingekho khona inkinga, futhi lingakhelwa kalula egiyeni lamanje.
Ngaphezu kokusebenza kwabo okuphezulu, lokhu kulula ukukufaka. Atholakala ngosayizi abaningi abahlukene, okwenza lokhu kungabi nankinga ekukhetheni okulingana kahle okuncamelayo. Amapayipi angavele ashiselwe, aboshwe, noma aboshwe ngomshini egiyeni lakho, kuqinisekiswe ukufakwa okuphephile nokuthembekile.
