Yog tias koj tau ua raws li kev lag luam khoom siv hauv tsev, tej zaum koj yuav pom tias kev lag luam xav tau rau fiber ntau cement boards tau nce zuj zus nyob rau xyoo tas los no. Vim li cas? Vim tias tib neeg tau maj mam paub tias nws yog cov khoom siv uas tuaj yeem siv sijhawm ntev hauv cov tsev thaum ua "kev txhawj xeeb-dawb." Nws yog noo noo- tiv taus, tuaj yeem tiv taus cua thiab tshav ntuj, thiab ua haujlwm zoo nkauj hauv lub tsev sab nrauv, sab hauv, thiab txawm nyob hauv qee qhov chaw ua haujlwm.
Tab sis hnub no, kuv xav tham nrog koj txog ob qhov kev hloov pauv loj uas tshwm sim hauv kev lag luam no - hloov pauv uas peb, uas yog cov neeg xa khoom, feem ntau xav qhia rau koj.
Ua ntej, "asbestos-dawb" tau dhau los ua cov kab hauv qab uas tsis tau hais.
Yog tias koj paub dab tsi txog fiber ntau cement boards, tej zaum koj yuav tau hnov txog "keeb kwm tsis zoo" cuam tshuam nrog asbestos. Ntau xyoo dhau los, qee cov qauv qauv tau suav nrog cov ntxhia fiber ntau los txhim kho lub zog ntawm cov laug cam. Txawm li cas los xij, tom qab kev tshawb fawb kho mob tau lees paub tias kev nqus cov asbestos fibers tuaj yeem ua rau mob hnyav rau tib neeg kev noj qab haus huv.
Yog li ntawd, cov qauv tam sim no yog qhov tseeb heev: asbestos- cov khoom pub dawb yog tib txoj hauv kev rau kev ua lag luam yav tom ntej.
Nyob rau hauv txhua lub rooj tsavxwm peb muab rau cov lag luam txawv teb chaws, koj yuav tsis pom ib kab ntawm asbestos. Peb tau hloov mus rau kev siv ib puag ncig tus phooj ywg cog fibers lossis siab -purity wood pulp fibers ua cov khoom siv ntxiv. Qhov no ua kom lub rooj tsavxwm muaj zog thiab lub zog thaum tshem tawm tag nrho cov kev pheej hmoo ntawm kev noj qab haus huv. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li Europe, North America, thiab Nyij Pooj, qhov chaw tsim khoom siv cov qauv nruj heev, "asbestos-}dawb" yog qhov tseem ceeb tshaj plaws rau cov khoom lag luam nkag mus rau hauv lub khw. Rau txhua tus tsim lub luag haujlwm lossis tus tsim tawm, xaiv cov asbestos-dawb boards tsis yog tsuas yog tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm tsim kho, tab sis kuj tseem hais txog kev cog lus ntev ntev rau cov neeg uas yuav siv lub tsev rau ntau xyoo tom ntej.
Qhov thib ob, "tsawg carbon" tau dhau los ua qhov taw qhia tseem ceeb thoob plaws hauv cov khoom lag luam.
Tej zaum koj yuav tau pom tias kev lag luam kev tsim kho thoob ntiaj teb tab tom tham txog "kev txo qis." Yav dhau los, peb yuav tau tsom mus rau qhov tuab thiab ntom ntawm cov laug cam. Tam sim no, tib neeg tab tom pib nug cov lus nug sib txawv: Lub zog siv hluav taws xob ntau npaum li cas thaum lub sij hawm tsim lub rooj tsavxwm no? Nws puas muaj cov khoom siv rov ua dua tshiab? Nws puas tuaj yeem pab txuag hluav taws xob thoob plaws tag nrho lub neej ntawm lub tsev?
Qhov no kuj yog qhov uas peb tau nqis peev ntau hauv kev hloov khoom dua tshiab hauv xyoo tas los no.
Piv txwv li, peb tau ua kom zoo dua qhov sib piv ntawm cov cement hauv cov txheej txheem tsim khoom thiab tab tom ua haujlwm los koom nrog kev lag luam ntau dua los ntawm -cov khoom lossis cov khoom siv rov ua dua tshiab, kom cov laug cam lawv tus kheej muaj "qis-cov pa roj carbon" pib los ntawm cov khoom siv raw. Lwm qhov txiaj ntsig zoo ntawm fiber ntau cement boards yog lawv cov kav ntev. Ib lub rooj tsavxwm tuaj yeem siv tau rau ntau xyoo yam tsis tas yuav hloov pauv, uas ib txwm txo qis "cov pa roj carbon emissions zais" piv rau cov khoom siv uas yuav tsum tau saib xyuas ntau zaus lossis hloov.
Yog li ntawd, thaum peb hais tias "asbestos-dawb thiab qis- carbon tau dhau los ua cov lus qhia tseem ceeb rau kev txhim kho kev lag luam," nws qhia txog kev hloov pauv muaj txiaj ntsig: cov khoom siv hauv tsev tsis yog txias, tawv steel thiab pob zeb; lawv tab tom pib xav txog tib neeg kev noj qab haus huv thiab ua lub luag haujlwm rau lub neej yav tom ntej ntawm lub ntiaj teb.
Raws li tus neeg muag khoom, kuv sib txuas lus nrog cov neeg siv khoom thoob plaws ntiaj teb txhua hnub, mloog lawv cov dab neeg txog huab cua hauv zos, cov qauv tsim vaj tsev, thiab kev tswj hwm ib puag ncig. Ntau ntxiv, kuv xav tias peb tab tom muab ntau tshaj li lub rooj tsavxwm nkaus xwb -peb tab tom muab cov kev daws teeb meem uas pab cov neeg tsim ua tiav lawv cov "tsev ntsuab" cov tswv yim.
