3. Kov tris(3- fluorophenyl) phosphine nrog kev saib xyuas siv cov cuab yeej tsis muaj hluav taws xob thiab cov khoom siv hauv av; xyuas kom cov thawv ntim kom meej meej thiab khaws cia rau hauv ib qho chaw tshwj xeeb, ruaj ntseg.
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 txias; zam kev sib cuag ncaj qha thiab tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog av.
2. Ua tib zoo sau cov spilled tris (3-fluorophenyl) phosphine CAS 23039-94-3 siv cov cuab yeej huv, qhuav los yog HEPA-filter nqus tsev vacuum, thiab muab tso rau hauv lub thawv kaw, sau npe rau pov tseg raws li cov khoom siv phom sij.
3. Ntxuav cov kab mob kom huv si nrog cov kuab tshuaj uas tsim nyog los yog cov tshuaj ntxuav tes hauv kev tswj xyuas; sau tag nrho cov khoom tsis huv thiab muab pov tseg kom ua raws li cov cai hauv zos, lub teb chaws, thiab thoob ntiaj teb rau halogenated thiab phosphorus- muaj cov pov tseg phom sij.
Cov ntaub ntawv kev nyab xeeb
1. Tris (3-fluorophenyl) phosphine muaj teeb meem yog tias nqos, nqus pa, lossis nqus los ntawm daim tawv nqaij, thiab tej zaum yuav ua rau tawv nqaij khaus, qhov muag loj, thiab ua pa ua pa.
2. Tris (3-fluorophenyl) phosphine CAS 23039-94-3 tuaj yeem tso tawm cov tshuaj fluoride lossis phosphorus oxides thaum cua sov lossis combustion; Ntev ntev los yog rov ua dua tuaj yeem cuam tshuam rau lub cev.
3. Ib txwm tuav tris (3- fluorophenyl) phosphine nyob rau hauv lub hood fume hood los yog nrog cov pa hauv zos txaus, hnav PPE tsim nyog nrog rau cov hnab looj tes tiv thaiv tshuaj, daim npog ntsej muag, tshuaj tsom iav, thiab khaub ncaws tiv thaiv.
