3. Cov neeg ua haujlwm 2-Cyanoacetamide CAS 107-91-5 yuav tsum hnav PPE tsim nyog suav nrog cov cuab yeej ua pa ntawm tus kheej (SCBA) yog tias tsim nyog thaum ntxuav; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog hauv dej . 2-Cyanoacetamide yog cais rau kev thauj mus los (UN 3439, Hazard Class 6.1, PG III).
Cov ntaub ntawv kev nyab xeeb
1. 2-Cyanoacetamide yog cais nrog GHS lub teeb liab lo lus "Kev Ceeb Toom" thiab muaj kev phom sij yog tias nqos tau (H302), ua rau tawv nqaij khaus (H315), khaus qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa (H335). Mob qhov ncauj LD50 (rat) yog 7230 mg / kg.
2. 2-Cyanoacetamide yog combustible nrog ib tug flash point ntawm 215℃(419℃F); thermal decomposition los yog combustion ua rau cov pa phem thiab irritating pa xws li carbon oxides, nitrogen oxides, thiab hydrogen cyanide. Nws ruaj khov nyob rau hauv ib txwm muaj tab sis tsis sib haum nrog cov muaj zog oxidizing cov neeg ua haujlwm, acids, thiab cov hauv paus.
3. Ib txwm sab laj nrog 2-Cyanoacetamide CAS 107-91-5 daim ntawv Qhia Kev Nyab Xeeb tshwj xeeb (SDS) rau 2-Cyanoacetamide kom paub cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P305+P351+P338 rau qhov muag, P301+P330+Pestion for 3 inhalation), thiab tuav cov lus qhia; 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).
