Lub ntsiab lus ntawm asbestos-muaj cov khoom yog dab tsi?
Asbestos, ib pawg ntawm cov zaub mov muaj fiber ntau, feem ntau siv hauv cov khoom siv hauv tsev kom txog thaum nws muaj kev phom sij rau tib neeg kev noj qab haus huv tau paub dav. Txhawm rau kom nkag siab zoo dua cov kev pheej hmoo cuam tshuam nrog asbestos, nws yog ib qho tseem ceeb rau kev txhais cov khoom siv asbestos (ACM). Hauv tsab xov xwm no, peb yuav tshawb xyuas cov ntsiab lus ntawm ACM, nws ntau hom ntawv, kev siv ntau, kev phom sij rau kev noj qab haus huv, thiab kev tuav pov hwm kom muaj kev nyab xeeb.
1. Nkag siab txog Asbestos-Containing Material (ACM)
Asbestos-muaj cov ntaub ntawv hais txog txhua yam khoom lossis cov khoom siv uas muaj asbestos fibers. Cov fibers no raug tso tawm rau saum huab cua thaum cov khoom no puas, tawg, lossis cuam tshuam. ACM tuaj yeem pom nyob rau hauv ntau yam khoom siv hauv tsev thiab cov khoom siv, xws li rwb thaiv tsev, qab nthab thiab cov vuas hauv pem teb, cov ntaub ntawv vov tsev, cov nplaum, cov nplaum, thiab lwm yam. Kev nqus pa ntawm asbestos fibers ua rau muaj kev pheej hmoo loj rau kev noj qab haus huv thiab tuaj yeem ua rau ntau yam kab mob ua pa, nrog rau mob qog noj ntshav thiab asbestosis.
2. Cov ntawv sib txawv ntawm ACM
ACM tuaj yeem muab faib ua ntau hom raws li nws muaj pes tsawg leeg thiab yuav ua li cas sib xyaw nrog lwm cov ntaub ntawv. Feem ntau cov qauv yog:
a) Friable ACM: Hom ACM no tuaj yeem tso tawm asbestos fibers yooj yim thaum kov lossis cuam tshuam. Nws tuaj yeem tawg mus rau hauv hmoov lossis hmoov av los ntawm txhais tes siab. Piv txwv ntawm friable ACM muaj xws li rwb thaiv tsev xoob, cov khoom siv hluav taws kub, thiab cov tshuaj tsuag-thov txheej.
b) Non-Friable ACM: Daim ntawv no ntawm ACM muaj cov asbestos fibers uas ruaj khov nrog cov khoom sib txuas, xws li cov cement lossis epoxy. Non-friable ACM ua rau muaj kev pheej hmoo tsawg dua ntawm kev tso tawm fiber ntau tshwj tsis yog nws puas los yog ua haujlwm kho dua tshiab uas cuam tshuam nws txoj kev ncaj ncees. Cov piv txwv muaj xws li asbestos-cement cov khoom xws li kav, shingles, thiab boards.
3. Kev siv ACM
ACM tau siv dav hauv ntau qhov kev lag luam vim nws cov khoom tsim nyog, xws li kub tsis kam, lub zog, thiab lub suab nqus. Qee qhov kev siv ntawm ACM suav nrog:
a) Kev tsim kho thiab kev rwb thaiv tsev: kev rwb thaiv tsev asbestos feem ntau yog siv hauv cov tsev los txhim kho kev siv hluav taws xob thiab hluav taws kub. Nws tuaj yeem pom hauv cov yeeb nkab thiab boiler rwb thaiv tsev, rwb thaiv tsev hauv tsev, thiab lwm yam.
b) Automotive Kev Lag Luam: Cov ntaub ntawv uas muaj cov asbestos tau dav siv rau kev rwb thaiv tsev kub hauv lub tsheb, xws li cov pawm nres, clutch faces, thiab gaskets, vim lawv cov cua sov thiab kav ntev.
c) Shipbuilding: Shipbuilding ua ntej xyoo 1980s feem ntau koom nrog ACM rau kev rwb thaiv tsev, hluav taws kub, thiab soundproofing. Cov ntaub ntawv no tseem tuaj yeem pom hauv cov hlab ntsha laus.
d) Kev tsim khoom: ACM tau siv los tsim ntau yam khoom siv, nrog rau cov vuas, xim, txheej, thiab textiles, txhim kho lawv lub zog thiab nplaim taws.
4. Health Hazards Associated with ACM
Thaum ACM cuam tshuam los yog puas, microscopic asbestos fibers raug tso tawm rau saum huab cua. Kev nqus dej ntawm cov fibers no tuaj yeem ua rau muaj teeb meem kev noj qab haus huv ntau dhau sijhawm, xws li:
a) Mob ntsws Cancer: Kev raug mob asbestos muaj kev cuam tshuam rau lub ntsws cancer. Asbestos fibers, thaum nqus tau, tuaj yeem nkag mus tob rau hauv lub ntsws thiab ua rau kev loj hlob ntawm tes tsis zoo hauv lub ntsws.
b) Mesothelioma: Cov qog nqaij hlav tsawg thiab hnyav no cuam tshuam rau lub ntsws, plab, lossis lub plawv. Nws yog yuav luag tsuas yog tshwm sim los ntawm asbestos raug thiab muaj lub sijhawm ntev latency, feem ntau tshwm sim ntau xyoo tom qab pib raug.
c) Asbestosis: Ntev nqus ntawm asbestos fibers tuaj yeem ua rau caws pliav thiab mob ntawm lub ntsws, ua rau asbestosis. Tus mob ua pa ntev no tuaj yeem ua rau ua pa luv, hnoos, thiab ua rau lub ntsws puas.
5. Kev tuav pov hwm kev nyab xeeb thiab tshem tawm ACM
Txhawm rau tiv thaiv cov tib neeg los ntawm kev raug mob asbestos, nws yog ib qho tseem ceeb uas yuav tau ua kom ACM muaj kev nyab xeeb thiab, yog tias tsim nyog, tshem nws kom raug. Nov yog qee cov ntsiab lus tseem ceeb uas yuav tsum xav txog thaum cuam tshuam nrog ACM:
a) Kev Paub Txog thiab Kev Qhia Txog Tus Kheej: Ua qhov kev ntsuam xyuas zoo ntawm thaj chaw txhawm rau txheeb xyuas qhov muaj peev xwm ACM. Koom nrog cov kws tshaj lij rau kev kuaj asbestos thiab tshuaj xyuas yog tias xav tau.
b) Kev Tiv Thaiv Kev Tiv Thaiv: Ua kom muaj kev tiv thaiv zoo, xws li kev sib khi, ntim khoom, lossis cov ntaub thaiv npog, kom txo qis kev tso tawm asbestos fiber ntau. Cov paib ceeb toom kom raug, khaub ncaws tiv thaiv, thiab khoom siv ua pa rau cov neeg ua haujlwm yuav tsum tau muab.
c) Kev tshem tawm nyab xeeb: Thaum ACM yuav tsum tau muab tshem tawm, ntiav cov kws tshaj lij uas muaj ntawv tso cai thiab muaj kev paub txog kev tshem tawm asbestos uas ua raws li cov txheej txheem kev nyab xeeb nruj thiab cov cai pov tseg.
d) Kev soj ntsuam tas mus li: Tsis tu ncua saib xyuas ACM kom ntseeg tau tias nws ruaj khov thiab txo qhov kev pheej hmoo ntawm fiber ntau tso tawm. Kev saib xyuas huab cua ib ntus tuaj yeem kuaj xyuas txhua qhov huab cua hauv asbestos fibers, ua kom muaj kev ua haujlwm sai.
Hauv kev xaus, kev nkag siab txog lub ntsiab lus ntawm cov khoom siv asbestos (ACM) yog qhov tseem ceeb rau kev paub txog kev pheej hmoo ntawm kev noj qab haus huv thiab kev ntsuas kev nyab xeeb tsim nyog. Muab cov kev phom sij loj heev cuam tshuam nrog kev raug mob asbestos, nws yog ib qho tseem ceeb uas yuav tsum tau ua, tswj, thiab tshem tawm ACM nrog kev saib xyuas los tiv thaiv tib neeg los ntawm nws cov teebmeem.
