Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav thiab ua kom muaj cua txaus. Muaj 2,2-Diphenylacetic acid siv cov khoom siv qhuav, inert, tsis-combustible absorbent thiab tiv thaiv kev nkag mus rau hauv cov dej ntws los yog cov dej.
2. Ua tib zoo cheb 2 2-Diphenylacetic acid CAS 117-34-0 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 hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tshuaj lom neeg- hnab looj tes tiv thaiv thiab tiv thaiv qhov muag thaum ntxuav. 2,2-Diphenylacetic acid raug cais raws li tsis muaj kev phom sij rau kev thauj los ntawm qee qhov kev cai (RIDADR: NONH rau txhua hom kev thauj mus los).
Cov ntaub ntawv kev nyab xeeb
1. 2,2-Diphenylacetic acid yog cais raws li ib qho irritant (Xi, GHS teeb liab lo lus "Ceeb toom"). Nws ua rau tawv nqaij khaus (R36/38, H315) thiab mob qhov muag loj (H319).
2. Kev mob toxicity 2 2-Diphenylacetic acid CAS 117-34-0 cov ntaub ntawv qhia tau hais tias qhov ncauj LD50 qhov tseem ceeb ntawm 5540 mg/kg hauv cov nas thiab 3200 mg/kg hauv cov nas, nrog rau kev pom muaj xws li kev hloov hauv lub cev muaj zog thiab ataxia . Intraperitoneal LD50 hauv nas yog 500 mg / kg, thiab subcutaneous LD50 yog 400 mg / kg.
3. Nyob rau hauv hluav taws kub, thermal decomposition lossis combustion ntawm 2,2-Diphenylacetic acid ua rau cov pa phem thiab khaus, nrog rau cov pa roj carbon oxides. Lub compound muaj qhov sib txawv ntawm qhov sib txawv ntawm 146-149℃thiab flash point ntawm 140 degree. Nco ntsoov sab laj nrog Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) 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).
