Manje izakhiwo eziphakeme zikhuphuka zisuka phansi, kodwa ubani onganaka ukuthi ubani osemva kwalokhu buthule, umsebenzi uthatha ingozi enkulu, ukuze kuqinisekiswe ukuthi umzimba wabantu, uzobona inetha lezintambo.

1.Inethi yezokuphepha kumele ilengiswe ngezansi kwendawo yokusebenza ephezulu;Lapho ubude besakhiwo budlula ama-4m, kufanele kusethwe inethi yokuphepha ikhuphuka kancane kancane nodonga, bese kumiswa inethi yokuphepha engashintshi njalo ngama-4m; Uhlaka lwangaphandle, uhlaka lwebhuloho, izimbobo ezingenhla nezingezansi kufanele zimiswe amanetha okuphepha.Ukumiswa kwenethi yokuphepha kufanele kube phansi futhi kube phezulu, futhi umehluko wengxenye yezindleko zenethi yentambo ngokuvamile cishe u-50cm;Akukho ukuphuka noma ukugoba. wenduku yokusekela;Igebe phakathi konqenqema lwangaphakathi lwenetha nodonga lingaphansi kuka-15cm;Ibanga phakathi kwendawo ephansi yenetha nobuso bento engezansi kufanele libe likhulu kuno-3m.Ububanzi bekhanda elincane Isigxobo sokhuni akufanele sibe ngaphansi kuka-7cm, ububanzi bekhanda elincane le-bamboo pole akufanele libe ngaphansi kuka-8cm, futhi ukuhlukana kwezinti zezintambo zokubopha inetha akufanele kube kukhulu kune-4m.

2.Hlola ukuthi inetha yokuphepha igqwalile futhi yonakele yini ngaphambi kokusetshenziswa.Ukwakhiwa kokuqinisekisa ukuthi inetha yokuphepha iphelele futhi iyasebenza, isekela okunengqondo, iyunifomu yokuphoqelela, akukho okuhlukile kunethiwekhi.I-lapping izoba iqine futhi iqine, ngaphandle kwezikhala.Inetha yokuphepha akufanele ihlakazwe noma yonakaliswe ngesikhathi sokwakha.Izohlakazwa kuphela uma umsebenzi wenziwa ngaphandle kokuphakama.Lapho inetha yokuphepha elakhiwe idinga ukudilizwa okwesikhashana ngenxa yokwakhiwa, iyunithi yokwakha kufanele yazise futhi icele imvume yeyunithi yokumisa ngaphambi kokudilizwa.Ngemva kokuphothulwa. wokwakha, iyunithi yokwakha kufanele iqale kabusha umsebenzi ngokushesha ngokuvumelana nezinhlinzeko futhi iphumelele ukuhlolwa kweyunithi yokwakhiwa ngaphambi kokuba isetshenziswe.

3. inetha lezintambo ngokuvamile ukuhlanza imfucumfucu enetheni, enetha ngaphezu kokuqaliswa kokushisela, kufanele kuthathwe izinyathelo eziphumelelayo zokuvimbela izinhlansi zokushisela ukuba ziwele enethini; Ungabi nesikhathi eside se-asidi eyingozi kanye nentuthu ye-alkali nxazonke. inetha.
