1) Ibanga ukusuka endaweni yokudlulisa yenzwa kuya ezingeni eliphansi loketshezi kufanele libe ngaphansi kobubanzi bethuluzi lokuzikhethela.
2) Ibanga ukusuka endaweni yokudlulisa yenzwa kuya ezingeni eliphakeme kakhulu loketshezi kufanele libe likhulu kunendawo engaboni yethuluzi lokuzikhethela.
3) Ubuso obudlulisa ulwazi lwenzwa kufanele buhambisane nobuso obuwuketshezi.
4) Indawo yokufaka inzwa kufanele ibe kude ngangokunokwenzeka ukuze kugwenywe indawo lapho izinga loketshezi lishintshashintsha khona kakhulu, njengokungena kanye nokukhipha okungezansi.
5) Uma udonga lwechibi noma ithangi lungasheleli, imitha kufanele ibe ngaphezu kuka-0.3m ukusuka odongeni lwechibi noma ithangi.
6) Uma ibanga elisuka ebusweni bomthumeli wenzwa liye ezingeni eliphakeme kakhulu loketshezi lingaphansi kwendawo engaboni yethuluzi lokuzikhethela, kuyadingeka ukufaka ithubhu yokwelula, ububanzi bethubhu yokwelula bukhulu kuno-120mm, ubude bungu-0.35m ~ 0.50m, ukufakwa okuqondile, udonga lwangaphakathi lubushelelezi, imbobo ethangini kufanele ibe nkulu kunobubanzi bangaphakathi bethubhu yokwelula. Noma ipayipi ingaba ngqo phansi kwethangi, ububanzi bepayipi bungaphezu kuka-80mm, kanti phansi kwepayipi kushiywe ukuze kube lula ukugeleza koketshezi.
