U-Paidu yingcali yaseTshayina ePhantsi ePhantsi komsi yeHalogen umenzi kunye nomthengisi. Iintambo ze-halogen ezingenalo umsi ophantsi kufuneka zihambelane nemigangatho yeshishini elifanelekileyo kunye nemimiselo elawula iintambo zombane kunye neemfuno zokhuseleko lomlilo. Ukuthotyelwa kuqinisekisa ukuba iintambo zihlangabezana nemilinganiselo ethile yokhuseleko kunye nokusebenza kwezicelo ezijoliswe kuzo.Iintambo ze-halogen ezingenayo umsi ophantsi zisetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo kunye namacandelo apho ukhuseleko, ukukhuselwa kokusingqongileyo, kunye nokumelana nomlilo kuyingqwalasela ebalulekileyo, njengezakhiwo zorhwebo, ukuthutha. iinkqubo, amaziko edatha, kunye nezibonelelo zoshishino. Ukukhethwa ngokufanelekileyo, ukufakwa, kunye nokugcinwa kwezi ntambo kubalulekile ukuqinisekisa ukuthembeka kunye nokhuseleko lweenkqubo zombane ngelixa kuncitshiswa impembelelo yokusingqongileyo.
