1. Kev npaj kho tshwj xeeb rau cov txheej txheem txhawb nqa yuav tsum tau tsim cov kab thaum ntxov pw ua ke;
2. Cov teeb tsa lub hauv paus ntawm cov qauv ntsuas phoo yuav tsum tau ua kom haum thiab theem thiab ua rau muaj kev tawv tawv thiab ua rau tawv tawv.
3. Cov phaj-thiab-tua scaffolding yuav tsum siv cov kev nce qib ntau ntawm cov nqaj, cov pob zeb, thiab cov phiaj hauv qab ntawm qhov nce ib yam. Thaum siv ib qho kev pab txhawb nqa cov ncej nrog qhov siab loj thiab ntsuas qhov nro (tseem ceeb ntawm cov npoo ntsug kom ntseeg tau tias qhov ruaj khov thiab kev nyab xeeb ntawm tus ncej;
4. Tom qab lub erection ntawm tus ncej yog ua tiav, txaus SCISSOR kev sib tw thiab kab rov tav ua kom paub tseeb tias qhov kev ruaj ntseg sab saum toj yog qhov kev lees paub tag nrho;
5 Tau kawg, peb cia siab tias cov chaw haujlwm tshwj xeeb yuav tsim cov kev sib raug zoo kom cov lus qhia kom raug rau qhov kev siv tau rau kev siv tshuab.
Tom qab shaft hom scaffolding yog tsa, nws muaj cov toj roob hauv pes zoo nkauj thiab tau dhau los ua cov kev xav tau zoo nkauj uas muaj cov kev tsim kho tsis zoo. Nws yog nyob rau hauv ntse sib piv rau lub tais qias neeg-khawm scaffolding.
