Cia thiab ceev faj
1. Khaws 2-Bromobenzaldehyde nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv inert gas (argon filling) nyob rau hauv ib tug txias, qhuav, thiab zoo-ventilated qhov chaw. Pom zoo cia qhov kub ntawm 0-8℃(txias) mus rau qhov chaw txias, qhuav kom deb ntawm qhov hluav taws kub. Nws yog huab cua rhiab heev thiab yuav tsum tau tiv thaiv los ntawm lub teeb.
2. Khaws 2-Bromobenzaldehyde kom deb ntawm cov khoom muaj zog oxidizing, muaj zog hauv paus, thiab muaj zog txo cov tshuaj tiv thaiv kom tsis txhob muaj kev puas tsuaj rau kev puas tsuaj.
3. Ib txwm siv 2-Bromobenzaldehyde CAS 6630-33-7 cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv, tsom iav, thiab khaub ncaws tiv thaiv; tsuas yog ua kom muaj cua txaus (fume hood) thiab tsis txhob ua pa pa, pos huab, lossis plua plav.
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. Muaj 2-Bromobenzaldehyde siv inert, uas tsis yog-combustible absorbent khoom thiab tiv thaiv cov ntaub ntawv los ntawm kev nkag mus rau hauv cov dej los yog cov dej.
2. Ua tib zoo 2-Bromobenzaldehyde CAS 6630-33-7 cheb los yog shovel cov kua uas nchuav / khoom rau hauv ib lub thawv ntim tshuaj khib nyiab pov tseg, muab pov tseg kom raug raws li kev cai hauv zos, xeev, thiab tseem fwv ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tshuaj lom neeg - cov cuab yeej tiv thaiv thiab tus kheej -cov cuab yeej ua pa (SCBA) yog tias tsim nyog thaum ntxuav; rau hluav taws, siv cov tshuaj tsuag dej, tshuaj qhuav, carbon dioxide, los yog cawv- ua npuas ncauj resistant rau tua .
Cov ntaub ntawv kev nyab xeeb
1. 2-Bromobenzaldehyde yog cais raws li cov kua combustible (flash point 95℃/ 203℃F). Nws ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa (H335). GHS teeb liab lo lus yog "Ceeb toom".
2. 2-Bromobenzaldehyde muaj qhov melting point ntawm 16-22℃thiab boiling point ntawm 230 degree. Thermal decomposition los yog combustion ua rau muaj kuab lom thiab irritating pa nrog carbon monoxide thiab hydrogen bromide gas. Nws muaj teeb meem yog tias nqos, sib cuag nrog daim tawv nqaij, lossis yog nqus tau (H302+H312+H332).
3. Nco ntsoov sab laj 2-Bromobenzaldehyde CAS 6630-33-7 cov ntaub ntawv tshwj xeeb Safety Data Sheet (SDS) rau 2-Bromobenzaldehyde kom ua tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P305+P351+P338 rau daim tawv nqaij, P{2}) cov lus qhia, P{2}; UN kev faib tawm yog UN2810 6.1/PG III tab sis qee qhov chaw faib ua tsis muaj kev phom sij rau kev thauj mus los.
