Izibani zamathayela phansiziwuhlobo lwezibani ezivalekile ezivame ukusetshenziswa phansi, odongeni noma kwezinye izindawo ezisicaba. Zisetshenziswa kabanzi ekuhlobiseni nasekukhanyiseni ngaphakathi nangaphandle. Ukwakheka kwezibani zamathayela phansi kuzivumela ukuthi zibe

zihlanzwe ngomhlaba noma udonga, okuyinto enhle futhi ewusizo. Lokhu okulandelayo yizici zezibani zamathayela phansi:

1. Umklamo ofakiwe:Izibani zamathayela phansingokuvamile zamukela umklamo ohlanganisiwe, ongagudla phansi noma odongeni, unciphise ukuvela futhi ugweme

ukukhubeka, futhi zifanele izindawo ezinethrafikhi enkulu.

2. Ukubukeka okuhlukahlukene: Izibani zamathayela phansi ziyatholakala ngezitayela nemibala ehlukahlukene, ezingahambisana nezitayela ezahlukene zokuhlobisa futhi zithuthukise konke

ubuhle.

3. Ukungangenwa ngamanzi nothuli: Izibani eziningi zamathayela phansi zisebenza kahle ngokungangenwa ngamanzi nothuli, zilungele ukusetshenziswa ngaphandle noma endaweni enomswakama

izindawo.

4. Ukonga amandla nokuvikela imvelo: Izibani zanamuhla zamathayela phansi zisebenzisa kakhuluIsibani se-LEDimithombo, enezinzuzo zokusebenza kahle okuphezulu,

ukusetshenziswa kwamandla okuphansi, nokuphila isikhathi eside, futhi kunganciphisa ngempumelelo ukusetshenziswa kwamandla.

5. Ukukhanya okuthambile: Amathayela aphansi ngokuvamile aklanyelwe ukukhipha ukukhanya okuthambile, okungadala isimo esikhululekile futhi afanele ukuzijabulisa, ukuzijabulisa noma

izindawo zasekhaya.
