Khaws cia rau ntawm qhov chaw qhuav, cov duab ntxoo, muaj qhov cua. 1. Thawv: Khaws Diethyl carbonate hauv airtight ntim ua los ntawm cov khoom siv tau sib xws xws li iav lossis qee yam plastics. Nco ntsoov tias lub thawv ntim khoom tau sau kom meej.
2. Kub: Khaws rau hauv qhov chaw txias thiab qhuav qhov chaw kom deb ntawm kev tshav ntuj ncaj qha thiab cov khoom kub. Pom zoo cia kub feem ntau yog qis dua 25 ° C (77 ° F).
3. Qhov cua: khw muag khoom hauv qhov chaw muaj cua zoo los tiv thaiv kev sib txuam ntawm cov vapors, uas yuav yog cov taws.
4. Tsis zoo: zam kev khaws diethyl carbonate nyob ze cov muaj zog, cov kua qaub lossis hauv paus kom nws hnov mob nrog cov tshuaj no.
5. Kev tiv thaiv hluav taws: diethyl carbonate yog cov nplaim taws thiab yuav tsum tau ceev tseg kom deb ntawm cov nplaim taws, txim taws thiab lwm yam kev tiv thaiv. Cov khoom siv hluav taws kom tsim nyog tua hluav taws yuav tsum muaj nyob ze.
6. Pov tseg: pov tseg cov khib nyiab lossis tsis siv diethyl carbonate raws li cov cai hauv zos.
1. Kev tswj xyuas ua raws li: Ua kom ua raws li cov kev cai hauv zos, thiab thoob ntiaj teb cov cai hais txog kev thauj mus los ntawm cov khoom phom sij. Qhov no suav nrog cov lus qhia ntawm cov koom haum xws li Asmeskas Lub Tuam Tsev Txhawb Kev Thauj Mus Los (DOT) lossis International Huab Cua Kev Koom Tes (Iiata) rau Cov Khoom Xa Khoom Cua.
2. Ntim khoom tsim nyog: Siv cov ntaub ntawv ntim uas tsim nyog uas tau tshaj nrog diethyl carbonate. Lub thawv yuav tsum tau siv cov ntaub ntawv thiab ua cov khoom siv uas tuaj yeem tiv thaiv cov tshuaj lom neeg ntawm diethyl carbonate.
3. Sau npe: Sau npe kom meej rau cov ntim nrog cov cim kev phom sij thiab tuav cov lus qhia. Qhov no suav nrog kev qhia tias cov ntsiab lus yog cov nplaim taws thiab tej zaum yuav muaj kev phom sij yog nqus tau lossis nqos tau.
4. Kev tswj kub: Xyuas kom cov kev thauj mus los yog tswj hwm kom tsis txhob muaj qhov kub thiab txias, uas yuav cuam tshuam rau kev ruaj ntseg ntawm diethyl carbonate.
5. Qhov no yuav suav nrog kev siv cov lus qhia thib ob.
6. Kev kawm: Ua kom cov neeg ua haujlwm tau koom nrog cov txheej txheem thauj mus los thiab nkag siab cov kev pheej hmoo cuam tshuam nrog cov tshuaj kho mob derloth.
7. Cov txheej txheem kev kub ntxhov: txhim kho cov lus teb ceev thaum muaj nchuav lossis raug xwm txheej thaum thauj khoom. Qhov no suav nrog cov khoom siv vill tsim nyog thiab cov khoom siv tiv thaiv tus kheej (PPE) npaj txhij.
Yog lawm, diethyl carbonate yog suav tias yog qhov txaus ntshai. Nov yog qee cov ntsiab lus tseem ceeb txog nws cov kev phom sij:
1. Flammability: diethyl carbonate yog cov kua hluav taws uas yuav taws yooj yim yog tias raug cua sov, txim taws lossis qhib hluav taws. Nws muaj flash flash ntawm kwv yees li 26 ° C (79 ° F), uas txhais tau tias nws tuaj yeem tsim cov nplaim taws uas tsis muaj kub.
2. Kev Noj Qab Haus Huv Daj: Raug rau Diethyl Carbonate yuav ua rau tawv nqaij, ob lub qhov muag, thiab ua pa. Kev nqus tau ntawm vapors tej zaum yuav ua rau kiv taub hau, mob taub hau, lossis teeb meem ua pa. Kev ntev lossis rov kis tau zoo dua tuaj yeem ua rau muaj kev puas tsuaj loj dua.
3. Ib puag ncig cov xwm txheej: diethyl carbonate tej zaum yuav ua rau muaj kev phom sij rau cov neeg muaj lub neej thiab tej zaum yuav ua rau ib puag ncig kev nyab xeeb ntev rau ib puag ncig. Nws yuav tsum daws thiab pov tseg kom zoo rau kev cuam tshuam tsawg rau ib puag ncig.
4. Kev tswj hwm kev faib tawm: Diethyl carbonate yog cais raws li cov tshuaj uas muaj kuab lom, uas yuav suav nrog kev sib raug zoo ntawm cov tshuaj lom neeg (GHS) thiab hauv zos ntawm kev nyab xeeb tshuaj.
