Uphahla, njengoko igama lisitsho, lubhekisa kuphahla olwenzelwe imisebenzi yabasebenzi. Olu hlobo lophahla ludla ngokuba namandla aphezulu okuthwala umthwalo kwaye lunokumelana nokuhamba kwabasebenzi, iindibano kunye nemisebenzi. Uyilo lophahla lunika ingqalelo ngakumbi kwiimpawu ezingatyibilikiyo, ezingangeni manzi kunye nezokugquma ubushushu ukuqinisekisa ukusetyenziswa okukhuselekileyo nokukhululekileyo. Ukongeza, uphahla lunokuxhotyiswa ngezityalo eziluhlaza, izibonelelo zokuzonwabisa, njl.njl., ukuphucula amava okuhlala. Kwizakhiwo zorhwebo, uphahla ludla ngokusetyenziswa njengendawo yokutyela evulekileyo, iqonga lokubukela okanye indawo yeziganeko ukwandisa ukusebenza kunye nomtsalane wesakhiwo.

Uphahla oluvulekileyo lusetyenziswa kakhulu ukukhusela isakhiwo sesakhiwo emoyeni nasemvuleni, kwaye uyilo lwaso lugxile ekumelaneni namanzi, ukuthintela ubushushu kunye nokuqina. Uphahla alusoloko lujongwa njengeemfuno zomsebenzi wabasebenzi, ngoko ke amandla okuthwala umthwalo aphantsi, kwaye alufanelekanga ukuba abasebenzi bahambe. Olu hlobo lophahla luthambekele ngakumbi kwizinto ezikhanyayo nezimelana nemozulu, ezifana neepleyiti zesinyithi, ii-asphalt shingles njalo njalo. Ukugcinwa kophahla oluvulekileyo kulula, ikakhulu kugxile ekugqibeleleni komaleko ongangeni manzi kunye nokuhlolwa rhoqo.

Nazi izinto ezibalulekileyo onokuzithelekisa phakathi kophahla olusetyenziswa ngabantu kunye nophahla olungasetyenziswa ngabantu:

Iimpawu Uphahla hayi uphahla

Umthamo ophezulu wokuthwala umthwalo, ufanelekile kwimisebenzi yabasebenzi abaphantsi, awufanelekanga ukuhamba kwabasebenzi

Uyilo lugxile ekungatyibiliki, kungangeni manzi, kungangeni manzi, kungangeni manzi, kungangeni manzi, kungangeni manzi, kuhlala ixesha elide

Ukhetho olubanzi lwezixhobo, ezigxile kwizinto ezilula nezimelana nemozulu

Ubunzima bokulungisa buphezulu, uhlolo oluqhelekileyo kunye nokugcinwa kuphantsi, ikakhulu kugxilwe kumaleko angangeni manzi

Xa ukhetha uhlobo lophahla, kubalulekile ukuqwalasela ukusetyenziswa okuthile, uhlahlo lwabiwo-mali kunye namandla okugcinwa kwesakhiwo. Nangona utyalo-mali lokuqala luphezulu, lunokubonelela abasebenzisi ngemisebenzi engaphezulu kunye namava; Uphahla lubiza kakhulu kwaye luyasebenza, kwaye lufanelekile kwizakhiwo ezineemfuno eziphantsi zomsebenzi wophahla.

Nokuba uphahla lunabantu okanye alunabo, uyilo nolwakhiwo lwalo kufuneka lulandele imigaqo nemigangatho efanelekileyo yokwakha ukuqinisekisa ukhuseleko nokuqina kwesakhiwo. Kwiindlela ezisebenzayo, ukhetho lophahla lukwafuna ukuqwalasela iimeko zemozulu zasekuhlaleni, isitayile soyilo kunye neemfuno zomntu ngamnye zabasebenzisi, ukuze kufezekiswe isiphumo esihle kakhulu sokwakha kunye namava okusebenzisa.
