Indawo yensimbi eye yaqhunyiswa futhi yasuswa ukugqwala ayinawo amabala abonakalayo kawoyela, futhi akukho okuxegayo.
okunamathiselwe njengesikhumba se-oxide, ukugqwala, okokunamathela ngopende, njll.
Ngemuva kokuqhuma kwesibhamu nokususwa kokugqwala, ingaphezulu lensimbi kufanele lingabi namabala abonakalayo kawoyela, isikali, ukugqwala, izimbotshana zopende, nokungcola, futhi okusele kufanele kunamathiselwe ngokuqinile.
Indawo yensimbi eye yaqhunyiswa futhi yasuswa ukugqwala akumele ibe nokunamathiselwe okubonakalayo okufana namabala kawoyela, isikali, ukugqwala, namakhompiyutha opende, futhi noma yimiphi imikhondo esele kufanele ibe amachashaza anombala amancane kuphela ngendlela yamachashazi noma imigqa.
Ingaphezulu lensimbi ngemva kokuqhuma kokudubula nokususwa kokugqwala alinazo izinamathiselo ezibonakalayo ezifana namabala kawoyela, izikali ze-oxide, ukugqwala, namakhompiyutha opende, futhi indawo engaphezulu iveza ukucwebezela kwensimbi okufanayo nokungaguquguquki.
