Isinyathelo sokucubungula umbhobho sidinga ngokungqongqo, apho inkqubo yokufudumala eshushu iyinkqubo ebaluleke kakhulu, apho ukwazisa oku kulandelayo ngexesha lombhobho wokufudumeza.

I-1, umbhobho kufuneka ukwazi ukondla enye yezo zakhiwo zetsimbi zazinokuqonda kakuhle Ngaphambi kokuqengqeleka, xa amandla okuguqula aphantsi kakhulu ngexesha lentsimbi eshushu ilula kakhulu. Kodwa ngenxa impahla umbhobho esele iqulathe ezinye ingot, ngoko phambi kokuba kuqengqeleka eshushu kufuneka akwazi ukuphumeza ezinye zazo ukuze aphelise ezo ingots, okwenza ukuba umthamo umbutho kunye nokomelela bakwazi ukufumana uphuculo oluthile, kwaye kananjalo umbhobho ngexesha inkqubo yokuqengqeleka eshushu nayo iya kufumana ukhuseleko oluninzi.

I-2, qiniseka ukuba ubeke ingqalelo kwicandelo ngalinye lombhobho linomlinganiselo wokushisa kuzo zonke iinkalo ngexesha lenkqubo eshushu yokugubungela, ukwenzela ukuba umbhobho unokuhlangabezana ngcono neemfuno zemiba eyahlukeneyo yezobuchwepheshe kamva. Ukongezelela, umbhobho wokufudumeza uya kuchaphazela isizathu esibaluleke kakhulu sobomi bombhobho.

I-3, kumbhobho ngexesha lenkqubo yokufudumala apho kuya kuba yinto engaphantsi kokulindela ingozi, kwaye ngoko ke kwinkqubo yokusebenza phakathi kwabo kufuneka kuthathwe ukunciphisa ukwenzeka kwezi ngozi.

I-4, kwinkqubo yokufudumala kwesalathisi kunye neemfuno zobugcisa ziyakwazi ukwenza umsebenzi obanzi wokulungiselela, ngaloo ndlela ukwandisa ubomi bombhobho.

I-5, umbhobho kwinkqubo yokufudumeza eya kuba lula kakhulu ukubangela umbhobho we-oxidative phenomena, ngaloo ndlela kuya kubakho ukulahlekelwa kwesisindo sokuqala, ngoko ke ngaphambi kokufudumeza kufuneka kukwazi ukuqwalasela izizathu.
