3. Tsis txhob tsim cov plua plav huab cua thaum lub sij hawm ntxuav kom tsis txhob ua pa tawm, thiab tshem tawm cov kab mob thiab cov khoom siv uas tsim nyog, kom ntseeg tau tias cov khoom spilled tsis nkag mus rau hauv cov dej los yog dej hauv chav dej.
4. Tshem tawm cov khoom khaws tseg 2 3-Dibromo-5-chloropyridine CAS 137628-17-2 cov khoom raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig, nyiam dua los ntawm kev tso cai los ntawm kev puas tsuaj los yog tswj incineration nyob rau hauv ib tug chemical incinerator nruab nrog afterburner thiab scrubber.

 

Kev tiv thaiv hluav taws

 

1. 2,3-Dibromo-5-chloropyridine tsis raug cais raws li cov nplaim hluav taws kub heev tab sis tuaj yeem decompose nyob rau hauv hluav taws kub, nrog lub teeb nyem ntawm kwv yees li 111℃thiab tej zaum yuav emit fumes lom thaum koom nrog hluav taws.
2. Siv cov hmoov qhuav qhuav, carbon dioxide, cawv- ua npuas ncauj, lossis cov tshuaj tsuag dej los tua hluav taws nrog cov khoom, xaiv qhov tsim nyog tua 2 3-Dibromo-5-chloropyridine CAS 137628-17-2 media raws li ib puag ncig ib puag ncig .
3. Cov neeg tua hluav taws yuav tsum hnav tus kheej- muaj cov cuab yeej ua pa thiab cov iav tiv thaiv tag nrho thaum tuav cov hluav taws kub 2,3-Dibromo-5-chloropyridine vim yog cov pa roj carbon monoxide, carbon dioxide, nitrogen oxides (NOx), hydrogen chloride, thiab hydrogen bromide .
4. Thaum lub sij hawm combustion, tej zaum yuav 2 3-Dibromo-5-chloropyridine CAS 137628-17-2 emit irritant thiab toxic fumes; txav cov thawv los ntawm qhov chaw tua hluav taws yog tias muaj kev nyab xeeb ua li ntawd, txias cov thawv ntim nrog cov tshuaj tsuag dej, thiab muaj cov hluav taws kub los tiv thaiv ib puag ncig.
