Yenzelwe njengenxalenye ebalulekileyo yendawo yoqeqesho oluxutyiweyo, indawo yokugcina nokuqina okwaneleyo kubaluleke kakhulu. Inkqubo yokugcina enomthamo ophezulu enamanqanaba amabini ukuze kube lula ukufikelela kuyo njengoko iimfuno zejimu zisanda. Ngenxa yekhonkco lokubonelela elinamandla kunye nemveliso ye-DHZ, ulwakhiwo lwesakhelo sezixhobo luhlala ixesha elide kwaye lunewaranti yeminyaka emihlanu.
