Taw qhia

Volatile organic compounds (VOCs) yog emission li gases los ntawm tej yam khib nyiab los yog kua.VOCs suav nrog ntau yam tshuaj, qee qhov yuav muaj kev cuam tshuam rau kev noj qab haus huv luv luv thiab ntev.Concentrations ntawm ntau VOCs yog tsis tu ncua siab nyob rau hauv tsev (txog kaum zaus siab dua) tshaj sab nraum zoov.VOCs raug tso tawm los ntawm ntau cov khoom lag luam uas suav nrog ntau txhiab.

Organic chemicals yog dav siv los ua cov khoom xyaw hauv cov khoom siv hauv tsev.Cov xim, varnishes thiab ciab tag nrho muaj cov kuab tshuaj organic, xws li ua ntau yam kev tu, tshuaj tua kab mob, tshuaj pleev ib ce, degreasing thiab cov khoom nyiam.Roj yog tsim los ntawm cov organic tshuaj.Tag nrho cov khoom no tuaj yeem tso cov organic tebchaw thaum koj siv lawv, thiab, rau qee qhov, thaum lawv khaws cia.

EPA Lub Chaw Haujlwm Saib Xyuas Kev Tshawb Fawb thiab Kev Txhim Kho "Tag Nrho Cov Txheej Txheem Kev Ntsuam Xyuas Tag Nrho (TEAM) Txoj Kev Kawm" (Cov Lus Qhia Kuv txog IV, ua tiav xyoo 1985) pom cov theem ntawm kwv yees li kaum ob cov pa phem ntau dua li 2 txog 5 npaug hauv tsev ntau dua li sab nraud, tsis hais seb cov tsev nyob rau hauv cov cheeb tsam nyob deb nroog los yog muaj kev lag luam loj heev.TEAM cov kev tshawb fawb tau qhia tias thaum tib neeg siv cov khoom uas muaj cov tshuaj organic, lawv tuaj yeem nthuav tawm lawv tus kheej thiab lwm tus kom muaj kuab paug siab heev, thiab qhov siab siab tuaj yeem nyob hauv huab cua ntev tom qab ua tiav.

Cov teebmeem kev noj qab haus huv

Cov teebmeem kev noj qab haus huv tuaj yeem suav nrog:

• Qhov muag, qhov ntswg thiab caj pas irritation
• Mob taub hau, poob ntawm kev sib koom tes thiab xeev siab
• Kev puas tsuaj rau daim siab, lub raum thiab lub hauv paus paj hlwb
• Qee cov organics tuaj yeem ua rau mob qog noj ntshav hauv cov tsiaj, qee qhov xav tau lossis paub tias ua rau mob qog noj ntshav rau tib neeg.

Cov cim tseem ceeb lossis cov tsos mob cuam tshuam nrog kev raug VOCs suav nrog:

• conjunctival irritation
• qhov ntswg thiab caj pas tsis xis nyob
• mob taub hau
• kev tsis haum ntawm daim tawv nqaij
• ua tsis taus pa
• txo qis hauv cov ntshav cholinesterase
• xeev siab
• emesis
• epistasis
• qaug zog
• kiv taub hau

Lub peev xwm ntawm cov tshuaj organic los ua kom muaj kev noj qab haus huv sib txawv ntawm cov uas muaj tshuaj lom heev, rau cov uas tsis paub txog kev noj qab haus huv.

Raws li nrog rau lwm cov pa phem, qhov twg thiab qhov xwm txheej ntawm kev noj qab haus huv yuav nyob ntawm ntau yam nrog rau theem ntawm qhov raug thiab lub sij hawm raug.Ntawm cov tsos mob tam sim ntawd uas qee cov neeg tau ntsib sai sai tom qab raug rau qee cov organics suav nrog:

• Qhov muag thiab ua pa ua pa ua xua
• mob taub hau
• kiv taub hau
• qhov muag tsis pom kev thiab tsis nco qab

Tam sim no, tsis paub ntau npaum li cas txog kev noj qab haus huv tshwm sim los ntawm qib ntawm cov organics feem ntau pom hauv tsev.

Qib hauv Tsev

Cov kev tshawb fawb tau pom tias theem ntawm ntau cov organics nruab nrab ntawm 2 mus rau 5 npaug ntawm sab hauv tsev dua li sab nraum zoov.Thaum lub sij hawm thiab rau ob peb teev tam sim ntawd tom qab qee yam kev ua ub no, xws li xim stripping, qib yuav yog 1,000 zaug tom qab sab nraum zoov theem.

Cov kauj ruam los txo qhov raug

• Ua kom qhov cua nkag thaum siv cov khoom uas emit VOCs.
• Sib ntsib lossis dhau qhov kev ceev faj ntawm daim ntawv lo.
• Tsis txhob khaws cov thawv qhib ntawm cov xim tsis siv thiab cov khoom zoo sib xws hauv tsev kawm ntawv.
• Formaldehyde, ib qho ntawm VOCs paub zoo tshaj plaws, yog ib qho ntawm ob peb cov pa phem hauv tsev uas tuaj yeem ntsuas tau yooj yim.
  • Txheeb xyuas, thiab yog tias ua tau, tshem tawm qhov chaw.
  • Yog tias tsis tuaj yeem tshem tawm, txo qhov cuam tshuam los ntawm kev siv lub sealant ntawm txhua qhov chaw ntawm lub vaj huam sib luag thiab lwm yam khoom siv.
• Siv cov txheej txheem kev tswj kab tsuag sib xyaw kom txo tau cov tshuaj tua kab.
• Siv cov khoom siv hauv tsev raws li cov chaw tsim khoom cov lus qhia.
• Nco ntsoov tias koj muab cov cua ntshiab kom txaus thaum siv cov khoom no.
• Muab cov thawv uas tsis siv lossis siv me me pov tseg kom zoo;yuav hauv qhov ntau uas koj yuav siv sai sai.
• Khaws kom deb ntawm me nyuam yaus thiab tsiaj.
• Tsis txhob sib xyaw cov khoom tu tsev tshwj tsis yog hais rau ntawm daim ntawv lo.

Ua raws li daim ntawv qhia ua tib zoo.

Tej zaum cov khoom tsim kev puas tsuaj feem ntau muaj cov lus ceeb toom txhawm rau txo qhov raug tus neeg siv.Piv txwv li, yog tias daim ntawv lo hais tias siv cov khoom siv nyob rau hauv qhov chaw uas muaj cua zoo, tawm mus sab nraum zoov lossis hauv thaj chaw uas muaj cov kiv cua tso rau siv.Txwv tsis pub, qhib qhov rais los muab qhov siab tshaj plaws ntawm huab cua sab nraum zoov.

Muab pov tseg ib nrab ntim cov khoom qub lossis cov tshuaj tsis xav tau kom nyab xeeb.

Vim tias cov pa roj tuaj yeem xau txawm tias los ntawm cov thawv kaw, ib kauj ruam no tuaj yeem pab txo qis cov tshuaj organic hauv koj lub tsev.(Nco ntsoov tias cov ntaub ntawv uas koj txiav txim siab khaws cia tsis yog nyob rau hauv qhov chaw uas muaj cua zoo xwb tab sis kuj muaj kev nyab xeeb ntawm cov menyuam yaus.) Tsis txhob cia cov khoom tsis xav tau pov tseg rau hauv cov khib nyiab.Tshawb nrhiav seb koj lub nroog lossis ib lub koom haum hauv koj lub zej zog txhawb cov hnub tshwj xeeb rau kev sau cov khoom pov tseg hauv tsev.Yog tias muaj hnub no, siv lawv pov tseg cov thawv uas tsis xav tau kom nyab xeeb.Yog tias tsis muaj hnub sau cia, xav txog kev npaj ib qho.

Yuav tsawg tsawg.

Yog tias koj siv cov khoom siv qee zaus lossis raws caij nyoog, xws li cov xim pleev xim, cov xim pleev xim thiab cov roj av rau qhov chaw sov lossis roj av rau cov nyom nyom, yuav tsuas yog ntau npaum li koj yuav siv tam sim ntawd.

Khaws cov emissions los ntawm cov khoom uas muaj methylene chloride kom tsawg.

Cov khoom siv uas muaj methylene chloride muaj xws li cov xim strippers, cov nplaum tshem tawm thiab cov xim aerosol.Methylene chloride paub tias ua rau mob qog noj ntshav hauv cov tsiaj.Tsis tas li ntawd, methylene chloride hloov mus rau cov pa roj carbon monoxide hauv lub cev thiab tuaj yeem ua rau cov tsos mob cuam tshuam nrog cov pa roj carbon monoxide.Ua tib zoo nyeem cov ntawv uas muaj cov ntaub ntawv muaj kev phom sij rau kev noj qab haus huv thiab kev ceeb toom ntawm kev siv cov khoom no kom raug.Siv cov khoom uas muaj methylene chloride sab nraum zoov thaum ua tau;siv sab hauv tsev tsuas yog tias thaj chaw muaj qhov cua zoo.

Ua kom raug rau benzene kom tsawg.

Benzene yog ib hom kab mob uas tib neeg paub.Lub hauv paus tseem ceeb hauv tsev ntawm cov tshuaj no yog:

• ib puag ncig haus luam yeeb
• khaws cia roj
• cov khoom siv xim
• tsheb emissions nyob rau hauv txuas garages

Cov kev ua uas yuav txo tau benzene raug suav nrog:

• tshem tawm kev haus luam yeeb hauv tsev
• muab qhov cua siab tshaj plaws thaum lub sij hawm pleev xim
• pov tseg cov khoom siv pleev xim thiab cov roj tshwj xeeb uas yuav tsis siv tam sim ntawd

Ua kom raug perchlorethylene emissions los ntawm cov ntaub ntawv tshiab qhuav-huv kom tsawg.

Perchlorethylene yog cov tshuaj siv dav siv hauv kev tu kom qhuav.Hauv kev tshawb fawb hauv chav kuaj, nws tau pom tias ua rau mob qog noj ntshav hauv cov tsiaj.Cov kev tshawb fawb tsis ntev los no qhia tau hais tias tib neeg ua pa qis ntawm cov tshuaj no ob qho tib si hauv tsev uas khaws cov khoom qhuav huv thiab thaum lawv hnav khaub ncaws qhuav.Cov tshuab ziab khaub ncaws rov qab khaws cov perchlorethylene thaum lub sij hawm ntxuav qhuav kom lawv txuag tau nyiaj los ntawm kev rov siv dua, thiab lawv tshem tawm ntau cov tshuaj thaum lub sij hawm nias thiab ua tiav.Txawm li cas los xij, qee cov tshuaj ntxuav kom qhuav tsis tshem tawm perchlorethylene ntau npaum li ua tau txhua lub sijhawm.

Ua cov kauj ruam kom txo koj qhov raug rau cov tshuaj no yog qhov ua tau zoo.

• Yog tias cov khoom qhuav qhuav muaj cov tshuaj tsw qab muaj zog thaum koj tuaj tos, tsis txhob txais lawv kom txog thaum lawv tau qhuav kom zoo.
• Yog tias cov khoom uas muaj tshuaj tsw qab raug xa rov qab rau koj ntawm kev mus ntsib tom ntej, sim siv lub tshuab ziab khaub ncaws sib txawv.
