2. Muab cov khoom sau 1,2-Dimethylimidazole tso rau hauv ib lub thawv ntim khoom ntim, sau cov tshuaj khib nyiab pov tseg kom raug raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig. Ntxuav cov kab mob kom huv si nrog dej.
3. Cov neeg ua haujlwm 1 2-Dimethylimidazole CAS 1739-84-0 yuav tsum hnav PPE tsim nyog nrog rau cov hnab looj tes tiv thaiv tshuaj thiab tiv thaiv qhov muag thaum ntxuav . 1,2-Dimethylimidazole yog cais raws li cov khoom corrosive rau kev thauj mus los (UN3263, Chav Kawm 8, PG II) thiab yuav tsum muaj pov tseg.
Cov ntaub ntawv kev nyab xeeb
1. 1,2-Dimethylimidazole raug cais raws li ua rau qhov muag puas tsuaj loj (H318), tawv nqaij khaus (H315), thiab muaj teeb meem yog nqos tau (H302). Nws raug suav hais tias muaj kev phom sij nrog GHS teeb liab lo lus "Danger" thiab muaj NFPA kev ntsuas kev noj qab haus huv ntawm 2 (mob txaus ntshai).
2. 1,2-Dimethylimidazole yog combustible nrog ib tug flash point ntawm 92℃(198℃F) thiab autoignition kub ntawm 896℃F. Nws cov thermal decomposition lossis combustion tuaj yeem tsim cov pa phem thiab ua rau khaus, suav nrog nitrogen oxides thiab carbon monoxide.
3. Ib txwm 1 2-Dimethylimidazole CAS 1739-84-0 sab laj rau Daim Ntawv Qhia Kev Nyab Xeeb tshwj xeeb (SDS) rau 1,2-Dimethylimidazole kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P305+P351+P338 rau qhov muag, P{1}), P{1}, P{1} tuav cov lus qhia; Cov lus ceeb toom tseem ceeb suav nrog P280 (hnav hnab looj tes tiv thaiv / qhov muag tiv thaiv) thiab cov khoom sib xyaw ua rau muaj tshuaj lom rau cov kab mob hauv dej nrog cov teebmeem ntev (WGK 2).
