Raws li peb txhua tus paub, kev teeb tsa cov ntsia hlau ntawm qhov chaw siab tshaj yog qhov txaus ntshai heev, thiab kev raug xwm txheej ntawm cov yeeb nkab steel poob los ntawm qhov chaw siab feem ntau tshwm sim. Tau ntev, thaum lub sij hawm tsim tsa cov tsev siab, cov neeg ua haujlwm ntawm cov neeg ua haujlwm txuas tas mus li ntawm qhov chaw sau ntom ntuag ua rau muaj kev xav tob tob rau tib neeg. Cov hauj lwm tsim kho cov kab lis kev cai niaj hnub ntsib ntau yam teeb meem xws li tawg yooj yim, tsis yooj yim, thiab qhov nyuaj hauv kev sib khi, thiab muaj ntau yam zais tsis nyab xeeb. Cov txheeb cais txheeb cais qhia tau hais tias ntawm cov neeg tuag ntawm ntau hom kev raug teeb meem kev tsim kho thoob plaws tebchaws, ntau dua 55% ncaj qha lossis ncaj qha cuam tshuam rau erection thiab siv scaffolding.
Txij li thaum qhov tshwm sim ntawm qhov ntse nqa lub ntsej muag rau cov tsev siab, nws tau siv dav hauv tsev thiab txawv teb chaws ntawm kev xav tsis thoob. Ntau lub tsev kawm ntawv tshiab xws li New Hong Kong Government Building thiab Amada Hotel hauv Dubai tau siv cov cuab yeej tshiab no. Tsoos scaffolding ib txwm yuav hloov los ntawm kev txawj ntse nqa lub tshuab thev naus laus zis rau cov tsev siab.
Scaffolding tau dhau los ua cov ntse nqa khoom nqa. Nws zoo li yooj yim, tab sis nws yog qhov tseeb qhov kev hloov pauv loj hauv tev naus laus zis hauv kev tsim kho. Nws yog qhov piav qhia meej ntawm kev hloov pauv ntawm kev tsim kho sai sai ntawm science thiab thev naus laus zis rau hauv kev tsim khoom.
