Ukuqonda iingcinga zobungqina bokuqhutywa kwaselwandle: Ukuqinisekisa ukhuseleko kwimimandla eyingozi.

Amadlala entambo yokuqhushumba kolwandle ayizinto ezibalulekileyo ezenzelwe ukuqinisekisa ukhuseleko kwimimandla apho izinto ezinokuvutha kunye nomoya oshushumbayo inokubakho. Ezi glandula zentsimbi ezikhethekileyo zibonelela ngendawo yokungena ekhuselekileyo kwaye ethembekileyo kwiintambo zombane ngelixa zithintela ukungena kwezinto eziyingozi. Kwimizi-mveliso enje nge-petrochemical, elwandle, kunye ne-oyile kunye negesi, ukusetyenziswa kolu
