1. Kev Nyob Hauv Tsev: Hauv cov tsev nyob, cov thawv xa khoom yog cov khoom siv hluav taws xob uas tseem ceeb. Lawv yog lub luag haujlwm rau kev faib hluav taws xob tuaj rau ntau chav thiab cov khoom siv, xws li teeb pom kev zoo, qhov (socket), cua txias, thiab lub tshuab rhaub dej. Cov kev hloov pauv hauv lub thawv xa khoom tso cai rau kev tswj xyuas kev sib txuas hauv Circuit Court yooj yim, ua kom muaj kev nyab xeeb thiab yooj yim siv hluav taws xob hauv tsev. Thaum cov khoom siv ua haujlwm tsis zoo lossis muaj ntau dhau, cov khoom siv tiv thaiv nyob rau hauv lub thawv xa khoom yuav qhib tam sim ntawd, txiav tawm cov khoom sib txuas los tiv thaiv kev sib tsoo thiab tiv thaiv kev nyab xeeb ntawm cov neeg hauv tsev neeg thiab cov khoom siv.
2. Kev Lag Luam Kev Lag Luam: Cov khw muag khoom, cov tsev ua haujlwm, tsev so, thiab lwm lub tsev lag luam muaj kev xav tau hluav taws xob loj thiab nyuaj. Cov thawv xa khoom hauv cov chaw no ua haujlwm ntawm kev faib thiab tswj cov khoom siv hluav taws xob ntau. Lawv yuav tsum tsis tsuas yog ua tau raws li lub zog xav tau ntawm cov khoom siv niaj hnub xws li teeb pom kev zoo, elevators, thiab cua txias, tab sis kuj tseem muab lub zog ruaj khov rau ntau yam khoom siv hluav taws xob xws li cov ntawv sau nyiaj ntsuab, cov teeb pom kev zoo, thiab cov khoom siv cua. Tsis tas li ntawd, kom haum rau lub sijhawm ua haujlwm ntev thiab cov neeg ua haujlwm siab ntws cov yam ntxwv ntawm cov tsev lag luam, cov thawv xa khoom yuav tsum muaj kev ntseeg siab thiab kev nyab xeeb kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm lub zog hluav taws xob thiab txo qis kev lag luam los ntawm kev siv hluav taws xob thiab lwm yam ua haujlwm tsis zoo.
3. Kev Lag Luam Kev Lag Luam: Kev tsim khoom lag luam suav nrog ntau yam khoom loj - nplai cov cuab yeej thiab cov txheej txheem nyuaj, xav tau kev ruaj ntseg thiab kev ntseeg siab ntawm lub zog. Cov thawv ntim khoom hauv cov nroj tsuag muaj lub zog rau ntau yam khoom siv, khoom siv hluav taws xob, thiab cov khoom siv tswj. Raws li cov kev xav tau ntawm kev lag luam sib txawv, cov thawv xa khoom tuaj yeem tsim nyob rau hauv cov kev qhia tshwj xeeb thiab hom, xws li lub thawv xa hluav taws xob, lub thawv teeb pom kev zoo, thiab lub thawv ntim khoom. Lawv ua kom muaj kev tswj xyuas meej thiab kev tiv thaiv cov cuab yeej siv hauv kev lag luam, kom ntseeg tau tias muaj kev ruaj khov thiab ruaj khov ntawm cov txheej txheem ntau lawm. Piv txwv li, hauv cov nroj tsuag steel, cov thawv xa khoom yuav tsum muab lub zog txhim khu kev qha rau steelmaking thiab dov cov cuab yeej ua haujlwm hauv siab - kub thiab siab - av noo ib puag ncig; hauv cov chaw tsim khoom siv hluav taws xob, cov thawv xa khoom yuav tsum ua kom tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob muaj zog ntawm siab -cov khoom siv hluav taws xob ntau lawm.
4. Kev Thauj Mus Los: Hauv cov chaw thauj mus los xws li tshav dav hlau, chaw nres tsheb ciav hlau, thiab chaw nres tsheb hauv av, cov thawv xa khoom ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj hluav taws xob. Lawv muab lub zog rau cov teeb pom kev zoo, cov escalators, cov cuab yeej siv kev ruaj ntseg, thiab cov khoom siv sib txuas lus, ua kom muaj kev ua haujlwm zoo ntawm cov chaw no thiab kev nyab xeeb ntawm cov neeg caij tsheb. Cov thawv ntim hluav taws xob kuj tau nruab rau hauv cov tsheb xws li tsheb, tsheb ciav hlau, thiab nkoj los muab lub zog rau ntau yam khoom siv hluav taws xob hauv lub tsheb, xws li teeb pom kev zoo, cua txias, kev sib txuas lus, thiab kev taw qhia, ua kom muaj kev nplij siab thiab kev nyab xeeb ntawm kev thauj mus los.
5. Cov Chaw Pej Xeem: Cov tsev kawm ntawv, tsev kho mob, tsev qiv ntawv, thiab lwm qhov chaw pej xeem kuj vam khom rau lub thawv xa hluav taws xob. Hauv cov tsev kawm ntawv, cov thawv xa khoom muab lub zog rau cov teeb pom kev zoo thiab cov khoom siv qhia hauv cov tsev qhia ntawv, chav kuaj, thiab cov tsev qiv ntawv. Hauv tsev kho mob, cov thawv ntim khoom muaj lub zog ruaj khov thiab txhim khu kev qha rau ntau yam khoom siv kho mob, cov cuab yeej siv tau zoo hauv chav ua haujlwm, thiab cov cuab yeej siv kho mob hauv pawg ntseeg, ua kom muaj kev ua haujlwm zoo ntawm kev kho mob. Hauv cov tsev qiv ntawv, cov thawv xa khoom muab lub zog rau cov teeb pom kev zoo thiab cov khoom siv hluav taws xob qiv, tsim kom muaj kev nyeem ntawv zoo rau cov neeg nyeem.
