2. Lub thawv faib khoom yuav tsum tau kuaj xyuas ua ntej kev teeb tsa kom paub tseeb tias nws ua haujlwm zoo.
3. Thaum txhim kho lub thawv faib hluav taws xob, yuav tsum kuaj xyuas qhov chaw teeb tsa kom paub tseeb tias tsis muaj kev cuam tshuam lossis roj teeb meem.
4. Ua ntej kev teeb tsa, lub thawv faib khoom yuav tsum tau kos raws li qhov loj me sab nraud ntawm lub thawv faib khoom, thiab ntau yam khoom siv hluav taws xob ntawm lub thawv faib khoom yuav tsum tau teeb tsa raws li kev faib tawm.
5. Lub thawv faib khoom yuav tsum tau teeb tsa raws li lub voj voog faib khoom thiab lub voj voog tswj, thiab tom qab ntawd yuav tsum tau kho thiab sib sau ua ke. Thaum lub sijhawm kho, lub qhov rooj ntawm lub thawv yuav tsum tau xauv kom nruj.
6, Lub thawv lub cev yuav tsum nyob ze rau cov khoom siv hluav taws xob.
7. Lub thav hlau hauv lub thawv faib khoom yuav tsum tau grounded zoo thiab yuav tsum tsis txhob puas tsuaj; thiab cov bolts rau kev txuas cov xov hlau hauv av yuav tsum tau nruj.
8. Cov thawv faib khoom yuav tsum tsis txhob ntub dej.
Kev siv thiab kev saib xyuas ntawm lub thawv faib khoom
1. Lub txee faib khoom yog ib hom thawv faib khoom rau kev tiv thaiv cov kab thiab cov khoom siv.
Feem ntau los ntawm lub txee faib khoom, kab hluav taws xob, qhov hloov pauv tiv thaiv kev xau thiab cov cuab yeej av.
2. Lub luag haujlwm ntawm cov thawv faib khoom
(1) Muaj lub luag haujlwm rau kev faib tawm thiab kev tswj hwm tam sim no, kev tiv thaiv thiab kev faib tawm ntawm ntau yam khoom siv hluav taws xob.
(2) Muab kev muab hluav taws xob rau ntau yam khoom siv thiab faib hluav taws xob.
(3) los tshuaj xyuas, tswj thiab tshuaj xyuas qhov rwb thaiv tsev ntawm cov kab uas tsis ua haujlwm, thiab hloov cov khoom uas tsis ua haujlwm raws sijhawm kom tiv thaiv kev tshwm sim ntawm hluav taws xob.
3. Kev faib tawm ntawm cov txee faib khoom
(1) Faib raws li hom kev tswj: txee tswj tes, txee tswj chaw taws teeb thiab txee tswj chaw taws teeb; faib raws li cov khoom siv hluav taws xob hauv txee: lub rooj tsavxwm faib hluav taws xob, tus tswj hwm tus tswv thiab cov khoom siv hluav taws xob pabcuam; faib raws li hom kev teeb tsa: lub thawv faib khoom ruaj khov, lub thawv faib tes tuav thiab lub thawv faib khoom ruaj khov thiab tuav tes ua ke.
