Cia thiab ceev faj
1. Khaws ethyltriphenylphosphonium bromide nyob rau hauv ib qho 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 ethyltriphenylphosphonium bromide CAS 1530-32-1 cais los ntawm cov muaj zog oxidizing cov neeg ua haujlwm, muaj zog acids, thiab cov khoom siv tsis sib xws kom tsis txhob muaj kev phom sij lossis decomposition.
3. Kov ethyltriphenylphosphonium 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 muaj cov nchuav los tiv thaiv ethyltriphenylphosphonium bromide hmoov av los ntawm kev ua pa.
2. Sau cov ethyltriphenylphosphonium bromide ethyltriphenylphosphonium bromide CAS 1530-32-1 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. Ethyltriphenylphosphonium bromide tuaj yeem ua rau tawv nqaij khaus, khaus qhov muag, thiab ua pa ua pa thaum raug plua plav lossis aerosols.
2. Ethyltriphenylphosphonium bromide CAS 1530-32-1 tuaj yeem tsim kev puas tsuaj yog tias nqos los yog 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.
