Yog lawm,ethyl acetate tshuaj(CAS 141-78-6) yog tshuaj lom rau tib neeg, tab sis theem ntawm kev pheej hmoo nyob ntawm tus nqi thiab lub sij hawm raug. Piv nrog rau ntau cov organic solvents, ethyl acetate muaj cov tshuaj toxicity tsawg. Txawm li cas los xij, kev nqus pa ntawm cov pa ntau, kev sib cuag ntawm daim tawv nqaij ntev, kev noj, lossis rov ua haujlwm dua tuaj yeem ua rau khaus, hauv nruab nrab lub paj hlwb (CNS) kev nyuaj siab, thiab lwm yam teeb meem kev noj qab haus huv. Nws muaj kev nyab xeeb rau kev siv nyob rau hauv kev lag luam thiab chaw kuaj ib puag ncig tsuas yog thaum ua haujlwm hauv qhov cua zoo nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE).
Dab tsi yog Ethyl Acetate Chemical?
Ethyl acetate (CAS No . 141-78-6, UN1173)yog ib qho xim tsis muaj xim, flammable ester nrog cov yam ntxwv ntawm txiv hmab txiv ntoo tsw. Nws yog dav siv los ua cov kuab tshuaj hauv cov coatings, inks, adhesives, pharmaceuticals, tshuaj pleev ib ce, zaub mov flavorings, kuaj extraction, thiab kas fes decaffeination.
Vim nws txoj kev lag luam thiab cov neeg siv khoom siv dav dav, ib qho ntawm cov lus nug feem ntau yog: Puas yog ethyl acetate muaj teeb meem rau tib neeg?
Raws li cov lus qhia los ntawm OSHA, NIOSH, New Jersey Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv (NJDOH), European Chemicals Agency (ECHA), thiab Kev Nyab Xeeb Cov Ntaub Ntawv (SDS), ethyl acetate nthuav tawm kev phom sij rau kev noj qab haus huv nyob rau hauv qhov raug ntau dhau, tab sis nws tsis suav tias yog tshuaj lom neeg thaum siv kom tsim nyog.

Puas yog Ethyl Acetate Toxic?
Ethyl acetate yog cais raws li Ntiaj Teb Kev Sib Raug Zoo (GHS) raws li:
- H225: Cov kua ua kua thiab vapor heev
- H319: Ua rau mob qhov muag loj
- H336: Tej zaum yuav ua rau qaug zog lossis kiv taub hau
Rov ua dua lossis ncua ntev ntawm daim tawv nqaij yuav tshem tawm cov roj ntsha ntawm daim tawv nqaij, ua rau dryness, tawg, los yog dermatitis.
Txawm hais tias ethyl acetate tuaj yeem cuam tshuam rau tib neeg kev noj qab haus huv thaum raug ntau dhau, nws tsis raug cais raws li tib neeg cov carcinogen los ntawm cov koom haum tseem ceeb xws li International Agency for Research on Cancer (IARC), US National Toxicology Program (NTP), lossis US Environmental Protection Agency (EPA).
Kev noj qab haus huv los ntawm Ethyl Acetate raug
1. Kev nqus pa
Kev nqus pa yog txoj hauv kev tshaj plaws ntawm kev kis hauv chaw ua haujlwm. Tsawg concentrations yuav ua rau mob me me ntawm lub qhov ntswg thiab caj pas, mob taub hau, thiab kiv taub hau ib ntus. Kev xav ntau dua tuaj yeem ua rau qaug zog, txo qis kev ceeb toom, kev sib koom tes tsis zoo, thiab kev nyuaj siab hauv nruab nrab (CNS) kev nyuaj siab.
Cov huab cua siab heev hauv qhov chaw kaw yuav tsim kev phom sij rau kev noj qab haus huv thiab xav tau kev kho mob tam sim.
2. Kev Tiv Thaiv Qhov Muag
Cov kua dej ethyl acetate tuaj yeem ua rau qhov muag khaus, liab, kub hnyiab, thiab kua muag ntau dhau. Yog tias cov tshuaj nkag mus rau hauv lub qhov muag, yaug lawv tam sim nrog dej huv kom tsawg li 15 feeb thiab nrhiav kev kho mob yog tias khaus ntxiv.
3. Tiv tauj daim tawv nqaij
Nws tsis yog yooj yim nqus los ntawm cov tawv nqaij tsis zoo, tab sis rov sib cuag tshem tawm cov tawv nqaij tiv thaiv roj. Cov teebmeem tshwm sim muaj xws li daim tawv nqaij qhuav, liab, tawg, thiab tiv tauj dermatitis tom qab kis tau ntev.
4. Kev noj haus
Kev nqhis dej tsis tshua muaj tshwm sim tab sis tuaj yeem ua rau xeev siab, ntuav, plab tsis xis nyob, thiab khaus ntawm lub plab zom mov.
Ntev -Lub Sij Hawm Tshaj Tawm
Kev rov ua haujlwm dua ntau lub hlis lossis xyoo tuaj yeem ua rau mob tawv nqaij mob thiab ua rau lub ntsws ua pa ntev yog tias tsis tswj xyuas kom raug.
Qee qhov kev tshawb fawb qhia tias kev raug mob ntev ntev tuaj yeem cuam tshuam rau lub siab lossis lub raum ua haujlwm hauv cov neeg ua haujlwm raug mob hnyav, txawm hais tias cov pov thawj tam sim no hauv tib neeg tseem muaj kev txwv, thiab cov koom haum tswj hwm loj tsis tau faib cov ethyl acetate raws li lub hom phiaj tshwj xeeb hauv lub cev muaj kuab lom nyob rau hauv ib txwm ua haujlwm raug txwv.
Yuav Ua Li Cas Txo Kev Raug Mob?
Cov kev coj ua nyab xeeb muaj xws li:
- Siv cov pa tso pa hauv zos hauv thaj chaw ua haujlwm.
- Tsis txhob ua pa hnyav vapors.
- Hnav tshuaj lom neeg- hnab looj tes tiv thaiv thiab txaws- pov thawj tsom iav.
- Khaws kom deb ntawm tshav kub, sparks, thiab qhib nplaim taws.
- Khaws cov thawv kaw kom nruj thaum tsis siv.
- Ntxuav tes kom huv si tom qab tuav.
- Hauv kev lag luam ib puag ncig, kev tswj xyuas engineering yuav tsum yog thawj txoj hauv kev tiv thaiv kev kis kab mob, nrog rau PPE ua kev tiv thaiv ntxiv.
Kev Pabcuam Ua Ntej
- Inhalation: Txav tus neeg mus rau huab cua ntshiab tam sim ntawd. Nrhiav kev kho mob yog tias cov tsos mob tshwm sim.
- Kev Tiv Thaiv Qhov Muag: Tshem lub qhov muag nrog dej huv li 15 feeb.
- Kev sib cuag ntawm daim tawv nqaij: Tshem cov khaub ncaws uas tsis huv thiab ntxuav kom huv nrog xab npum thiab dej.
- Noj: Tsis txhob ua rau ntuav. Yaug lub qhov ncauj thiab tau txais kev kho mob tam sim ntawd.
