Kev ceev faj rau kev khaws cia rau hauv lub khw txias, qhuav, thiab zoo-ventilated warehouse.
Tseg deb ntawm hluav taws thiab cov khoom cua sov. Khaws lub thawv ntim kaw kom nruj.
Nws yuav tsum tau muab cais cais los ntawm oxidants, txo cov neeg sawv cev, acids, alkalis, thiab tshuaj noj kom huv thiab tsis txhob sib xyaw.
Nruab nrog cov khoom tsim nyog ntau thiab ntau thiab ntau ntawm cov khoom siv hluav taws.
Cov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kub ceev thiab cov khoom siv cia khoom haum.
1. Kev ruaj khov thiab kev ruaj khov
2. Cov ntaub ntawv tsis sib haum acids, alkalis, cov oxidants muaj zog, muaj zog txo cov neeg sawv cev, dej
3. Cov xwm txheej kom tsis txhob sib cuag nrog tshav kub
4. Polymerization phom sij, tsis muaj polymerization
Yog, diethyl oxalate yog suav tias yog txaus ntshai. Nov yog qee cov ntsiab lus tseem ceeb txog nws cov kev phom sij:
1. TOxicity: diethyl oxalate yuav ua rau muaj kev phom sij yog noj, nqus tau, lossis nqus los ntawm daim tawv nqaij. Nws yuav ua rau cov tawv nqaij ua rau lub qhov muag, ob lub qhov muag, thiab ua pa ua pa.
2. Carcinogenicity: Qee qhov kev tshawb fawb tau pom tias cov tshuaj oxalates yuav muaj cov teebmeem carcinogenic, txawm hais tias dialin outfous tus kheej tsis tau cais los ua tus paub tib neeg carcinogen.
3. Cov kev cuam tshuam ib puag ncig: diethyl oxalate yog kev phom sij yog ua rau muaj lub neej ntawm lub neej thiab tej zaum yuav muaj kev cuam tshuam ntev ntawm ib puag ncig.
4. Flammability: nplaim taws, cia kom deb ntawm cov nplaim taws, txim taws thiab cov cua sov.
5. Kev ceev faj kev nyab xeeb: Thaum tuav diethyl oxalate, ib txwm siv cov hnab looj tes tsim nyog (PPE) xws li kev tiv thaiv, thiab kev ua pa yog tias tsim nyog. Ua haujlwm hauv qhov chaw muaj cua zoo lossis siv cov lus ntim ntsej muag.
1. Kev tswj xyuas ua raws li: Xyuas kom koj ua raws li hauv zos, cov kev tswj hwm hauv tebchaws thiab thoob ntiaj teb hais txog cov khoom thauj khoom uas txaus ntshai. Qhov no yuav suav nrog kev tso cai tsim nyog thiab ua raws cov lus qhia tshwj xeeb rau kev thauj cov tshuaj.
2. Ntim khoom tsim nyog: Siv cov ntaub ntawv ntim uas tsim nyog uas tau sib xws nrog diethyl oxalate. Feem ntau, qhov no cuam tshuam siv cov thawv ntim khoom ua kom muaj cov iav lossis haum plastics thiab tso lawv hauv cov thawv hauv theem ob kom tiv thaiv tau cov khoom nchuav.
3. Sau npe: Sau npe kom meej meej daim ntawv nrog lub npe tshuaj lom neeg, cim kev phom sij, thiab cov ntaub ntawv muaj kev phom sij. Qhov no suav nrog cov lus qhia daws teeb meem thiab cov ntaub ntawv tiv toj thaum muaj xwm ceev.
4. Cov ntaub ntawv: Npaj thiab suav nrog txhua cov ntaub ntawv xa khoom xa khoom xws li cov ntaub ntawv pov thawj kev nyab xeeb (SDS), thiab cov cai tswj kev xa khoom.
5
6. Zam Tsis Pub Raug: Ua kom cov neeg thauj khoom uas tau kawm ua cov ntaub ntawv phom sij thiab nkag siab cov kev pheej hmoo cuam tshuam nrog diethyl oxalate.
7. Cov txheej txheem thaum muaj xwm ceev: txhim kho cov txheej txheem thaum muaj xwm txheej ceev los daws cov hnoos qeev lossis raug xwm txheej thaum thauj khoom. Qhov no suav nrog kev npaj cov khoom txau thiab cov khoom siv ua ntej.
8. Hom kev thauj: Xaiv hom tsim nyog ntawm thauj (txoj kev, huab cua, hiav txwv) uas ua raws li cov kev cai txaus ntshai. Cov qauv sib txawv yuav muaj cov cai tshwj xeeb.
