Dab tsi ntawm cov khoom siv pov tseg coverall yog tsim rau asbestos?

Asbestos tau siv dav hauv cov khoom siv hauv tsev txij li xyoo 19th vim tias nws cov khoom tsim nyog xws li yoog raws, ua haujlwm ntev, thiab ua haujlwm kub. Txawm li cas los xij, tam sim no peb paub tias kev cuam tshuam rau asbestos tuaj yeem ua rau muaj teeb meem kev noj qab haus huv, suav nrog mob ntsws cancer thiab mesothelioma. Yog li ntawd, txhua tus neeg uas tuaj yeem cuam tshuam nrog asbestos yuav tsum hnav cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) kom txo qis kev pheej hmoo ntawm kis. Ib qho tseem ceeb ntawm PPE yog qhov pov tseg pov tseg. Hauv tsab xov xwm no, peb yuav tshawb txog cov ntaub ntawv sib txawv ntawm cov khoom siv pov tseg uas tsim nyog siv nrog asbestos.

Ua ntej thiab qhov tseem ceeb tshaj plaws, nws yog ib qho tseem ceeb kom nkag siab txog dab tsi yuav tsum tau los ntawm cov khoom pov tseg pov tseg hauv cov xwm txheej uas cov neeg ua haujlwm yuav raug rau asbestos. Lub coverall yuav tsum muab lub cev tiv thaiv ntawm tus neeg hnav daim tawv nqaij thiab tej asbestos fibers uas tej zaum yuav muaj nyob rau hauv cov huab cua los yog ntawm qhov chaw. Lawv kuj yuav tsum tau muab pov tseg kom lawv thiaj li raug tshem tawm thiab muab pov tseg kom zoo tom qab siv, yog li txo qhov kev pheej hmoo ntawm kev sib kis.

Ib qho ntawm cov khoom siv feem ntau siv rau cov khoom siv pov tseg yog polypropylene. Polypropylene yog cov khoom siv hluavtaws uas yog lub teeb yuag, breathable, mos, thiab xis hnav. Nws kuj tseem pheej yig, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv ib zaug siv pov tseg coveralls. Polypropylene yog non-abrasive, yog li nws yuav tsis khawb lossis puas qhov chaw, uas tuaj yeem cuam tshuam asbestos fibers. Ntxiv mus,polypropylene npogmuaj cov tshuaj tiv thaiv zoo heev, uas yog qhov tseem ceeb vim tias cov neeg ua haujlwm yuav tsum tau siv cov tshuaj tshem tawm asbestos los ntawm qhov chaw.

Lwm cov khoom siv feem ntau siv rau cov ntaub npog pov tseg yog microporous. Microporous yog ib qho flashspun high-density polyethylene fibers uas yog spun rau hauv cov khoom uas muaj kev ntxhib los mos zoo li ntawv. Cov khoom siv tiv taus dej, tshuaj lom neeg, thiab kua muag, ua rau nws zoo tagnrho rau kev siv tshuaj asbestos.Microporous khaub ncawskuj yog qhov hnyav heev thiab ua pa, uas ua rau cov neeg ua haujlwm nyob zoo thiab ua haujlwm zoo thaum ua haujlwm txaus ntshai.

Nylon yog lwm cov khoom tsim nyog siv rau hauv cov khoom pov tseg thaum tuav asbestos. Nylon yog qhov tshwj xeeb ruaj khov, hnav, thiab ua pa, tso cai rau kev txav mus los tsis muaj kev txwv thiab yoog raws. Nws kuj tseem tiv taus dej, roj, kev puas tsuaj, thiab tsim kua muag, ua kom nws nyob ruaj khov txawm tias nyob rau hauv cov xwm txheej nyuaj, tiv thaiv kev tso tawm ntawm cov fibers txaus ntshai.

Kev sib xyaw ntawm polyethylene thiab polypropylene feem ntau yog siv rau hauv cov khoom siv pov tseg uas tsim los rau kev tshem tawm asbestos. Cov txheej txheej polyethylene muab cov dej tsis sib haum, thaum txheej txheej polypropylene yog qhov ua haujlwm zoo thiab ua pa, ua rau nws zoo meej rau kev siv hauv thaj chaw uas muaj cov asbestos fibers. Kev sib xyaw ntawm cov ntaub ntawv no ua rau muaj kev sib npaug ntawm kev nplij siab, kev cia siab, thiab kev tiv thaiv. Cov suits yog non-linting, uas txhais tau hais tias lawv tsis tso cov fibers uas yuav kis tau qhov chaw.

Nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom siv pov tseg uas yuav muab kev tiv thaiv kev tiv thaiv asbestos fibers. Kev nyab xeeb ntawm tus neeg ua haujlwm yuav tsum ua qhov tseem ceeb tshaj txhua yam. Polypropylene, microporous, thiab nylon yog cov kev xaiv tsim nyog rau cov khoom pov tseg pov tseg thaum tuav cov asbestos, vim lawv muab kev ua pa zoo, ua haujlwm ntev, thiab tshuaj lom neeg. Xaiv cov khoom tsim nyog rau txoj haujlwm tuaj yeem txo qhov kev pheej hmoo ntawm kev raug mob thiab ua kom cov neeg ua haujlwm muaj kev nyab xeeb. Nco ntsoov, asbestos yog qhov txaus ntshai, thiab txhua qhov kev ceev faj yuav tsum tau ua kom txo qis kev raug mob; qhov no suav nrog kev siv cov khaub ncaws tiv thaiv uas tsim nyog rau txoj haujlwm.
