Cia thiab ceev faj
1. Khaws diphenylphosphoryl azide rau hauv qhov txias, qhuav, zoo- qhov chaw cua, nyob rau hauv qhov chaw tsis muaj zog yog tias ua tau, thiab kom deb ntawm tshav kub, poob siab, kev sib txhuam, thiab cov khoom siv tsis sib xws. Cov tub yees feem ntau pom zoo.
2. Khaws Diphenylphosphoryl azide CAS 26386-88-9 lub thawv ntim kom nruj thiab muaj cov ntawv sau meej meej. Khaws cais los ntawm kev txo cov neeg ua hauj lwm, cov kua qaub, cov hauv paus, cov hlau hnyav, thiab cov khoom siv hluav taws xob. ** Tsis txhob sib cuag nrog dej lossis noo noo ** .
3. Ua tib zoo ceev faj siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE): tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, daim npog ntsej muag, thiab lub foob pob tawg- tiv thaiv lub chaw sim. Ib txwm siv lub fume hood thiab tawg- cov khoom pov thawj.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm tam sim ntawd thiab cais thaj chaw loj. Tsis txhob kov cov khoom uas nchuav. Ceeb toom cov tub ceev xwm thiab cov kws tshaj lij tawg.
2. **Tsis txhob sim ntxuav.** Ruaj Ntseg Diphenylphosphoryl azide CAS 26386-88-9 hauv cheeb tsam, tiv thaiv kev nkag mus, thiab tos rau cov neeg ua haujlwm ua haujlwm tawg / phom sij. Cia kom deb ntawm dej.
3. Tiv thaiv txhua yam khoom los ntawm kev nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Decontamination yuav tsum tau ua los ntawm cov kws txawj nkaus xwb.
Cov ntaub ntawv kev nyab xeeb
1. Diphenylphosphoryl azide yog **muaj tshuaj lom heev, corrosive, thiab noo noo-sensitive.** Nws ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab ua pa puas. Ua phem yog nqos los yog nqus tau. Decomposes tso ** muaj kuab lom heev thiab tawg hydrazoic acid (HN3) roj **.
2. **Nws YOG IB TUG TXIV NEEJ HNUB NYOOG.** Diphenylphosphoryl azide CAS 26386-88-9 yog kev poob siab-sensitive, kev sib txhuam-sensitive, thiab kub-rhiab heev. Muaj peev xwm detonate hnyav, tshwj xeeb tshaj yog thaum muaj concentrated, rhuab, los yog paug.
3. **Cov ntaub ntawv no tsuas yog yuav tsum tau ua los ntawm cov neeg ua haujlwm tsim nyog nrog kev cob qhia tshwj xeeb hauv cov khoom tawg thiab siab -cov ntaub ntawv siv hluav taws xob.** Nco ntsoov sab laj nrog tus nom diphenylphosphoryl azide Safety Data Sheet (SDS) thiab ua raws li tag nrho cov kev cai tawg (xws li ATF, OSHA). Siv qhov tsawg kawg nkaus thiab kev tswj hwm engineering.
