Ib txwm Sodium tert-pentoxide CAS 14593-46-5 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov tshuaj lom neeg- cov hnab looj tes tiv thaiv, nruj nruj tsom iav tsom iav los yog daim npog ntsej muag, thiab cov khaub ncaws tiv thaiv nplaim taws. Kov tsuas yog ua kom muaj cua txaus rau hauv lub hood fume, siv cov khoom pov thawj tawg, thiab tsis txhob ua pa plua plav / vapors.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab xyuas kom muaj cua txaus. Tsis txhob siv dej; kiag li tiv thaiv kev sib cuag nrog ya raws. Muaj Sodium tert-pentoxide siv qhuav, inert, tsis yog- cov khoom siv hluav taws xob (cov xuab zeb qhuav lossis lub ntiaj teb).
2. Ua tib zoo cheb los yog nqus cov khoom spilled siv lub txim hluav taws xob -cov cuab yeej pov thawj, tsis txhob muaj plua plav, thiab muab cov khoom khaws cia rau hauv qhov chaw kaw, sau npe corrosion- cov khoom pov tseg pov tseg kom raug raws li cov khoom siv phom sij.
3. Cov neeg ua haujlwm Sodium tert-pentoxide CAS 14593-46-5 yuav tsum hnav cov tshuaj lom neeg tag nrho- cov cuab yeej tiv thaiv suav nrog cov cuab yeej ua pa ntawm tus kheej (SCBA) thaum ntxuav. Tiv thaiv kom tsis txhob nkag mus rau hauv qhov dej los yog txoj kev dej. Sodium tert-pentoxide yog cais rau kev thauj mus los (UN3206 lossis UN2925, Hazard Class 4.2/8, Packing Group II).
Cov ntaub ntawv kev nyab xeeb
1. Sodium tert-pentoxide yog cais nrog GHS teeb liab lo lus "Danger". Nws ua rau tawv nqaij kub hnyiab heev thiab qhov muag puas tsuaj loj (H314/H318), yog cov khoom tawg yooj yim (H228) thiab nws tus kheej- cua sov (H251), tuaj yeem ua rau ua pa ua pa (H335), thiab muaj teeb meem rau ntawm daim tawv nqaij (H312) thiab yog nqus tau (H332). NFPA kev ntsuas kev noj qab haus huv yog 3 (kev phom sij hnyav).
2. Sodium tert-pentoxide reacts hnyav nrog dej, tso cov pa roj carbon monoxide (hydrogen) uas tuaj yeem ua rau kub hnyiab tau. Thermal decomposition ua rau cov pa phem thiab khaus khaus xws li carbon monoxide thiab carbon dioxide. Nws yog noo noo-sensitive thiab incompatible nrog muaj zog oxidizing tus neeg saib xyuas thiab acids. Flash point rau cov kev daws teeb meem sib txawv (xws li -20℃rau 35% THF tov).
3. Ib txwm Sodium tert-pentoxide CAS 14593-46-5 sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Sodium tert{18}}pentoxide kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P303+P361+P353 rau daim tawv nqaij, P305+P351+P338+P310 rau qhov muag, P304+P340+P310 rau kev nqus pa, P301+P330+P331 rau kev noj - tsis txhob ntuav ntuav), thiab cov lus qhia tuav . Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib hluav taws), P235+P410 (kub, tiv thaiv tshav ntuj), P260 (tsis txhob ua pa plua plav), thiab P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv).
