Iingcebiso zokuthenga ikheji yezinja

1. Jonga inkangeleko: akukho bundu bungaziwayo, ukukrweleka, umbala ofanayo kunye nezinye iimfuno zeplastiki; Iimfuneko zezinto zentsimbi ezingenamhlwa, ivumba,ikheji yenja.

2. Jonga ukuwelda: ukuwelda kufanele kube yinto efanelekileyo ukuze izilwanyana zasekhaya zingaphumi kunye nekhadi.

3. Jonga ipeyinti yokutshiza: iimfuno zonyango lomphezulu wokuqhumisa isanti, umhlwa ogqunywe nge-galvanized kumphezulu, ipeyinti yokubhaka enobushushu obuphezulu.

4. Ubunzima bokuthwala: amandla okuthwala kufuneka abe nengqondo kwaye abe namandla.

5. Jonga ezantsi kwekheyiji: ezantsi kwekheyiji kufuneka yenziwe nge-encryption, ukuze inja ikwazi ukuhlala kamnandi kwaye izikhulule.
