Cia thiab ceev faj
1. Khaws Carbic anhydride rau hauv lub thawv kaw nruj nreem nyob rau hauv cov roj inert nyob rau hauv ib qho chaw txias, qhuav, thiab zoo- qhov cua, kom deb ntawm tshav kub thiab ncaj qha tshav ntuj. Pom zoo cia rau hmoov yog nyob ntawm -20℃rau kev ruaj ntseg mus ntev .
2. Khaws Carbic anhydride nruj me ntsis kom deb ntawm cov dej noo, muaj zog oxidizing cov neeg ua haujlwm, muaj zog acids, thiab cov hauv paus muaj zog los tiv thaiv kev puas tsuaj los yog cov tshuaj tiv thaiv.
3. Ib txwm siv Carbic anhydride CAS 129-64-6 cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav tiv thaiv ntsej muag, thiab khaub ncaws tiv thaiv; tsis txhob ua pa plua plav thiab siv tsuas yog muaj qhov cua txaus (fume hood).
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais thaj chaw nchuav, tsis txhob muaj plua plav, thiab muaj Carbic anhydride siv inert, tsis yog -cov khoom siv hluav taws xob tawg; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog txoj kev dej.
2. Ua tib zoo cheb los yog shovel cov spilled Carbic anhydride cov khoom siv tsis yog - cov cuab yeej ua pa taws thiab tso cov khoom ntim rau hauv lub kaw, sau cov tshuaj khib nyiab Carbic anhydride CAS 129-64-6 ntim rau kev pov tseg kom raug raws li hauv zos, xeev, thiab tsoomfwv cov kev cai ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tus kheej - muaj lub tshuab ua pa thaum ntxuav; rau hluav taws, siv cov tshuaj tsuag dej, cawv- ua npuas ncauj, tshuaj qhuav, lossis carbon dioxide extinguishing media .
Cov ntaub ntawv kev nyab xeeb
1. Carbic anhydride yog cais nrog GHS teeb liab lo lus "Danger" vim tias nws ua rau qhov muag puas tsuaj loj (H318), yuav ua rau muaj kev tsis haum ntawm daim tawv nqaij (H317), thiab tej zaum yuav ua rau muaj kev tsis haum lossis mob hawb pob lossis ua pa nyuaj yog tias nqus tau (H334). NFPA kev ntsuam xyuas kev noj qab haus huv yog 3 (qhov raug luv luv tuaj yeem ua rau muaj kev raug mob hnyav ib ntus lossis nruab nrab qhov seem).
2. Carbic anhydride yog combustible thiab yuav emit irritant pa taws thaum combustion. Thermal decomposition ua cov pa phem xws li carbon oxides. Qee qhov chaw faib cov Carbic anhydride CAS 129-64-6 tsis yog ib yam khoom txaus ntshai, tab sis cov ntaub ntawv SDS qhia tau hais tias muaj kev phom sij loj rau kev noj qab haus huv uas yuav tsum tau ceev faj txog kev tuav pov hwm.
3. Nco ntsoov sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Carbic anhydride kom tiav cov ntaub ntawv txaus ntshai, ua ntej- cov txheej txheem pab (P305+P351+P338 rau qhov muag, P302+P352 rau daim tawv nqaij, P304+P340 rau kev nqus pa), thiab cov lus qhia tuav; Cov lus ceeb toom muaj xws li P261 (tsis txhob ua pa plua plav), P280 (hnav hnab looj tes tiv thaiv / tiv thaiv qhov muag), P284 (hnav tiv thaiv ua pa), thiab P342+P311 (yog tias muaj cov tsos mob ua pa).
