Cia thiab ceev faj
1. Khaws tetraphenylphosphonium bromide nyob rau hauv qhov chaw txias, qhuav, zoo- qhov chaw cua, tiv thaiv lub teeb thiab noo noo, nyob rau hauv cov thawv kaw nruj nreem ua los ntawm cov khoom siv sib xws.
2. Khaws tetraphenylphosphonium bromide CAS 2751-90-8 cais los ntawm cov muaj zog oxidizing cov neeg ua haujlwm, muaj zog acids, thiab cov khoom tsis sib xws los tiv thaiv kev phom sij lossis kev puas tsuaj.
3. Kov tetraphenylphosphonium bromide nrog kev saib xyuas kom txo tau cov hmoov av; xyuas kom cov thawv ntim kom meej meej thiab kaw thaum tsis siv.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav thiab ua kom muaj cua txaus; ua tib zoo ntim cov nchuav los tiv thaiv tetraphenylphosphonium bromide hmoov av los ntawm kev ua pa.
2. Sau cov tetraphenylphosphonium bromide tetraphenylphosphonium bromide CAS 2751-90-8 siv cov cuab yeej huv, qhuav los yog HEPA-filter nqus tsev vacuum, thiab muab tso rau hauv ib lub thawv uas haum, sealable rau pov tseg.
3. Ntxuav cov kab mob kom huv si nrog dej ntau; sau tag nrho cov khoom tsis huv (absorbents, ntxuav dej) thiab muab pov tseg raws li cov cai hauv cheeb tsam ib puag ncig rau cov tshuaj khib nyiab.
Cov ntaub ntawv kev nyab xeeb
1. Tetraphenylphosphonium bromide tuaj yeem ua rau tawv nqaij khaus, khaus qhov muag, thiab ua pa ua pa thaum raug plua plav lossis aerosols.
2. Tetraphenylphosphonium bromide CAS 2751-90-8 tuaj yeem ua rau muaj kev phom sij yog tias nqos lossis nqus tau, thiab qhov ntev los yog rov ua dua tuaj yeem ua rau lub cev puas tsuaj.
3. Nco ntsoov sab laj nrog Daim Ntawv Qhia Txog Kev Nyab Xeeb (SDS) kom paub cov ntaub ntawv toxicological tshwj xeeb thiab hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE), suav nrog cov npog plua plav, tsom iav, hnab looj tes, thiab khaub ncaws tiv thaiv.
