Daim pleev hlau loj rau kev tsim tsev ntau yam

Cov yeeb yam tias vim li cas daim pleev hlau loj yuav tsum muaj rau kev tsim kho tsev ntau yam

Qhov chaw tsim khoj tau yuav xav tau cov khoom siv uas tsim los rau kev siv hauv qhov chaw nyob meem. Cov raj nplaim dej siv rau kev tsim khoj tseemceeb muaj peev xwm txhim kho tseem ceeb dua li lwm yam siv. Txheej yuav tsis tuaj sib raug thaum kawm nyhj, thiab aluminum feem ntau yuav yog tshem siab dua. Cov raj nplaim dej no tuaj yeem tso tawm nrog ntau dua 140 pawg ntawm ib square foot tsis tas tshem siab raws li OSHA standards. Qhov no txhais tau hais tias lawv tseem ceeb dua thaum lawv tso tawm ntau tus neeg nrog tag nrho lawv cov khoom nyob saum qhov chaw nyob meem, qhov chaw uas kev ploj tuaj yeem ua rau tuag.

Lub roj kom kom tshuaj khaus yuav pab tiv thaiv kev phom sij, tiv thaiv kev ntxha taws nyob rau hauv siv khoom siv nyob rau hauv dej ntsia thiab xaim, yog li ntawd khoom siv nyob rau hauv chaw sib zog lossis nyob ze rau sab nraud yuav nyob ntev dua. Kev nyob zoo tseem ceeb ntau: cov planks tsos tsis tuaj yeem dag dag thaum ua haujlwm sib zog, txwv tsis pub tias cov dej nkhw thiab tsis tuaj yeem hla tau. Nyob rau hauv kev nyiaj yuav tsos feem ntau los ntawm 20 mus rau 30% ntau dua li cov dej nkhw, tab sis sau ua leej twg: cov tsos no feem ntau nyob ib xyoo ntev dua 15 xyoo ua ntej yuav tsum hloov kho, kom txo kev siv nyiaj kho kom txog saum dua ob thirds raws li qhov pom zoo los ntawm Ponemon hais tias nyob rau hauv 2023. Thiab tsis txhob nrhiav rau tus nqi nyiaj uas tau txo nyob rau qhov chaw twg: cov ntaub ntawv hais tias cov chaw ua haujlwm tso caij li 740,000 dola uas tsis tas tsum xa los ntawm kev tiv thaiv kev puas tsuaj rau neeg laj neeg. Thaum tsis muaj qhov chaw sai, tshwj tsis pub nyob rau hauv qhov chaw muaj kev nyuaj siab, yuav tsis tsuas yog tsos planks tsuas yog ib qhov uas pab tiv thaiv kev ua haujlwm zoo.

Zaj tswj hli ntau thiab kev nyob zoo sib cuam tshuam OSHA rau kab rooj planking rau scaffold

Xaiv kom paub txog qhov loj ntawm zaj tswj hli: 75 psf compared to 140 psf kab rooj planking rau scaffold

Cov pa roj sib ntsig los ntawm chaw tsim kho tsev yuav tsum tau siv cov neeg loj uas tuaj yeem pab kom tsis txhob muaj kev puas tsuaj lossis muaj teeb meem hauv qab cheeb. Qhov chaw saib xyuas keev kwm zoo li ntawm keev cai yuav tsum tau kom cov pa no tig tau ib feem plaub ntawm yam uas lawv xav tau los tig - nyob zoo ib txwm muaj keev cuam tshuaj. Rau cov hlo rau tseem ceeb hauv chaw tsim kho, cov pa roj sib ntsig me me thiab medium duty uas muaj zeej tshaj tawm ntawm 25 los ntawm 50 pawg ib square foot yog tsim nyog. Tab sis thaum mloog mus rau hauv kev tsim kho tsev, tsis muaj dab tsi zoo dua li cov pa roj sib ntsig loj uas muaj zeej tshaj tawm 140 psf. Cov pa roj sib ntsig no tseem ceeb dua, tsis txhob muaj kev puas tsuaj thaum muaj neeg ntau tus, lub tsev, thiab mortar (uas loj dua 75 psf thaum muaj dej), thiab lwm yam khoom siv thiab chaw tsim kho. Xaiv mus rau qhov leej: ib daim pa roj sib ntsig zoo 140 psf tuaj yeem tig tau ib feem 2,800 pounds ntawm ib daim platform 20 square foot. Yog li ntawd yog ib feem plub dua li cov khoom tsawg zeej tshaj tawm 75 psf. Thiab peb yuav tsum pom zoo, tsis muaj leej twg xav ua haujlwm hauv ib daim tawm uas yuav tsum tau muaj kev puas tsuaj. Txhawm rau OSHA hais tseg hais tias nyob rau hauv 2023, ib feem rau ntawm rau cov neeg tuag hauv scaffolding yog tshwm qab los ntawm cov platform uas tsis tuaj yeem tig yam uas lawv xav tau los tig.

Nthoj Siab OSHA rau kev Tshwm Hnub, Ntev ntawm qhov chaw, thiab Kev Txwv ntawm Planking

Kev nyob rau txwv tsis yog ib yog tshuaj xyuas ntau dua li tso cai rau tib neeg mus, tab sis tseem muaj peb lub tswv yim tseemceeb tshaj plaws:

OSHA 1926.451(a)(1) thim kom tsis txhob muaj yaj duab ncaj ncees tsis muaj qhov kho taw, thiab qhov kho taw yuav tsum nyob ib leeg nrog qhov tshuab nres. Qhov tsis ua raws nraim no yuav muaj kev tuaj kom tau txog $156k saib xyuas ib zaug (OSHA 2024). Thaum sau tom qhov muaj kab ntsug, kab khaus lossis kab tshuv—txh especially tom qab pom tib neeg siv dej lossis khoom siv—yuav pab txhim kho lub sijhawm siv thaum twv tau kev tswj zwm tseem ceeb.

Kev nyob ntev hauv qhov chaw nyuaj: Kab khaus, dej ntsuab, thiab tsoom phoob

Lub rooj pov av siv rau kev tshuab nres uas tiv thaiv kab khaus thiab kev pab hloov cov hlau rau kev tshuab nres

Nyob hauv qhov chaw tsim kho siv rau kev lag luam, cov raj xaav tau raug kuaj xyuas los ntawm txoj lej ntau yam uas tso caij lom tes, xws li khoom siv sib npib, av tog cua nyob ze sab nraud, thiab dej no tsis txo. Lub steel planks nyob tam sim no muaj kev tiv thaiv tau zoo dua los ntawm cov ntxhua hlau tshwj xeeb xws li hot dip galvanizing thiab cov epoxy polyurethane ntxhua hlau tseem ceeb uas ua haujlwm zoo heev rau kev tiv thaiv tau 15 mus rau 20 xyoo, h even nyob ze saum toj khaum. Cov hlau alloy tuaj yeem zoo dua lawm. Cov chromium nickel sib thooj tau txo cov teeb meem pitting los ntawm li 40 feem pua tshiab kom compared with carbon steel khoom siv tshaib. Tag nrho cov kev txhim kho no nyob hauv khoom siv yog tias structures nyob ib si zog thiab nyob ib si nyob zoo tom qab xyoo ntawm kev raug sib cuag nrog conditions loj nyob rau hauv qhov chaw tsim kho tag nrho.

Kev ua haujlwm rau hauv dej ntxoos, masonry, thiab kev siv ntau hauv kev lag luam

Kev nyob zoo ntawm kev pab cuam tshuam rau kev tshuam xyuas nyob rau hauv qhov chaw nyob tsis zoo yog tias yuav tsum muaj kev kho mob rau cov teeb meem no. Thaum muaj qaum, cov chaw sib ntxiv uas tsis tuaj yeem slip no tau txiv nyob rau hauv kev pab tswj xyuas kom tsis tuaj yeem luv luv. Ib co kws cim cim pom tias qhov no tuaj yeem khawm kev luv luv los ntawm 32%, raws li OSHA tau sau tseg los ntawm hnub no rau hnub. Cov neeg ua haujlwm masonry feem ntau nyiam cov duab ntawm hardened steel alloys uas siv rau cov planks no vim tias lawv tuaj yeem tso tseg tawm ntawm concrete dust thiab mortar residue tsis txhob puav tsov. Cov chaw ua haujlwm uas muaj neeg ntau tuaj yeem nrhiav tau cov planks uas muaj kev pab ntau dua kom tsis txhob muaj kev hloov pauv tom qab ib tug neeg ntau npaum li 100 tus neeg tshuam tawm li ib hnub. Thiab tsi txhob saib tsis meej rau kev nyob ruaj khov tseem ceeb. Cov zinc aluminum coating uas siv rau cov planks no tau raug nrog rau ASTM E136 uas txhais tau tias cov spark tawm los ntawm welding yuav tsis tuaj yeem tso cov planks no tawm. Qhov no tau txiv nyob rau hauv kev pab nyob ruaj khov rau cov chaw xwb xwm xws li oil refineries lossis rau sab nraud ntawm cov dej siab uas kev tshwm sim tuaj yeem ua rau muaj kev phem.

Siv Lub Tshuab Scaffolding Steel Plank Uas Muaj Kzuj Lim Thaj Tsam Los Tswj Ntshai, Nyiam Daim Kab Hliav Thiab ROI

Tus Tswv Ceev OSHA-Stamped Certification Thiab Qhov Chaw Tswj Ntshai

Thaum pib mus rau qhov kev siv txaj hluas tshuab hluas rau kev lag luam, kev nyab xeeb rau neeg ua haujlwm yog qhov tseem ceeb tshaj plaws. Txaj no muaj kev tuag zoo nrog OSHA, thiab tshwj tsis tau siv ntau yam kev sim ua ntej khiav khoom rau hauv zauv. Qhov dab tsi ua rau nws raug siab? Saib xyuas rau cov ntawv pov thawj uas tso tseg rau lawv qhov meej ntsua, thiab lub qhov chaw tsis slip thiab lub chaw kho kom txhua yam nyob deb tawm hauv kev tshuab hluas. Rau kev nyab xeeb, lub guardrails yuav tsum nyob haum, thiab ntau yam khoom yuav tsum faib tshwm dav rau hauv txhais kab, uas yuav cuam tshuam kev hlub dua. Cov leej cipher kuj hais lus tseem ceeb - cov chaw tsim khoom uas muaj kev puas tsuaj los ntawm khoom tsawg khaum feem ntau siv li $740,000 thaum ib zaug raws li Ponemon's 2023 report. Cov chaw tsim khoom zoo tshaj plaws tso vim ntau dua los ntxiv cov rooj khaus dej thiab cov rooj tshuab tiv thaiv rau rust, thiaj li tias lawv khoom tau tag nrho ASTM A1204 standards rau kev tshawb nrhiav dej thiab tshuab hluas hauv cheeb tsam.

Txoj Cai Zoo Tshaj Rau Kev Sauv Xam, Saibxyuas, thiab Siv Ntau Zasaem

Yog xav siv ntau zasaem rau qhov muag hlau tuab ntoo, yuav tsum muaj kev cai tswj hwm:

• Kev sauv xam hnav xyoo : Sauv xam kom pom tias puav muag muaj kev txiav txim, cov kab ruag zoo li cas, thiab kev nyiaj ruag ntawm qhov muag
• Sauv kom sov : Siv duab uas tsis muaj qhov pH kom tshem cov duab pob lossis duab kemtawm tawm
• Cov kho tsev kho tsev : Ceev npoo tawv raws ib cheeb laub kom tso cov dej tawm
• Hloov kho qhov muag ntawm sab npaug : Hloov tib moment ntawm qhov muag uas tau raug khaum

Kev xaiv siv cov khoom galvanized tuaj yuav tsum sau nrog 20+ xyoo hauv qhov chaw nyob ze bira siab yog tias them kom raug. Tsis txhob siv cov cleaner uas ua rau hmoob, thiab rov kho cov chaw rust nrog siv paint muaj zinc ntau los tiv thaiv kev cuam tshisha. Cov kev ua no tuaj yeem txo kev hloov planks mus li 40%, nyob rau tib siab ROI.
