Njengoko izixhobo zombane zisiya zisiba nzima ngakumbi nangakumbi, ziyafuneka izincedisi ezingakumbi, nto leyo ekhokelela kwiisekethe ezininzi kunye nezincedisi kwiPCB.Kwangaxeshanye, iimfuno zomgangatho wePCB isinxibelelanisi sangoku esiphezulu nazo ziphuculwe.I-Ass PCB ephezulu isinxibelelanisi sangoku ithatha unxibelelwano lobhedu olubomvu kunye nesilivere yokucwenga umaleko, ophucula kakhulu ukusebenza kwangoku kwePCB isinxibelelanisi sangoku esiphakamileyo, kunye neendlela zofakelo ezahlukeneyo zinokuhlangabezana neemfuno zofakelo zabathengi abahlukeneyo.
