●Iinkqubo zeminyango yesibhedlele ziyinxalenye ebalulekileyo yengaphakathi lesibhedlele.Ukongeza kwimbonakalo, ukulula ukucoca kunye nomgangatho ophezulu, ngokukodwa ukulawulwa kweengcango zonyango kubaluleke kakhulu.
●Umzekelo, kudla ngokuba kubaluleke kakhulu ukuba ucango lwesibhedlele lungavulwa xa kufuneka luhlale luvaliwe, umzekelo kwigumbi lokuhlala yedwa okanye kwisebe le-X-reyi.Okanye ukuba iingcango zesibhedlele ezityibilikayo zivunyelwe ukuba zivuleke, kodwa kuphela ukuba oko kuyimfuneko ngokwenene.Njengomzekelo, ucango OKANYE, apho umoya okwigumbi OKANYE kufuneka uhlale ucocekile kangangoko.Ezinye iingcango zesibhedlele kufuneka zivuleke kwaye zivale ngokuzenzekelayo, ngaphandle kokufuna isenzo sesandla.
