Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav thiab ua kom muaj cua txaus. Muaj 4-Ethoxybenzoic acid siv cov khoom siv qhuav, inert, tsis-combustible absorbent (xws li, xuab zeb) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws los yog cov dej.
2. Ua tib zoo cheb 4-Ethoxybenzoic acid CAS 619-86-3 nce cov khoom nchuav uas siv cov cuab yeej huv si, tsis muaj teeb meem, tsis txhob muaj plua plav, thiab muab cov khoom khaws cia rau hauv cov thawv ntim tshuaj khib nyiab pov tseg kom raug raws li kev cai hauv zos, xeev, thiab tseem fwv ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tshuaj lom neeg- cov hnab looj tes tiv thaiv thiab tiv thaiv qhov muag thaum ntxuav. 4-Ethoxybenzoic acid tsis raug cais raws li cov khoom phom sij rau kev thauj los ntawm qee cov cai.
Cov ntaub ntawv kev nyab xeeb
1. 4-Ethoxybenzoic acid yog cais nrog GHS teeb liab lo lus "Warning". Nws ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319), thiab tej zaum yuav ua rau ua pa ua pa (H335) . 4-Ethoxybenzoic acid CAS 619-86-3 kuj raug cais raws li kev phom sij yog tias nqos tau (H302) los ntawm qee qhov chaw.
2. 4-Ethoxybenzoic acid muaj qhov melting point ntawm 195-201℃thiab tshwm raws li cov hmoov dawb crystalline . Nws yog combustible, thiab thermal decomposition lossis combustion tuaj yeem tsim cov pa phem thiab khaus, nrog rau cov pa roj carbon monoxide.
3. Nco ntsoov sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau 4-Ethoxybenzoic acid kom tiav cov ntaub ntawv txaus ntshai thiab cov txheej txheem pab thawj zaug (P305+P351+P338 rau qhov muag, P302+P352 rau daim tawv nqaij, P304+P340 rau kev nqus pa). Cov lus ceeb toom muaj xws li P261 (tsis txhob ua pa plua plav), P280 (hnav looj hnab looj tes tiv thaiv qhov muag), thiab P405 (khoom kaw cia).
