2. Sau 2-(4-Methylphenyl)propanoic acid CAS 938-94-3 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav uas siv cov cuab yeej tsis muaj teeb meem, thiab muab tso rau hauv cov thawv kaw tsim nyog rau kev pov tseg.
3. Tsis txhob tsim cov huab cua thaum lub sij hawm ntxuav kom tsis txhob ua pa; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov dej ntws los yog cov dej hauv cov dej raws li kev tawm mus rau ib puag ncig yuav tsum zam.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig los ntawm kev tso cai los ntawm kev puas tsuaj los yog kev tswj incineration.
Kev tiv thaiv hluav taws
1. 2-(4-Methylphenyl) propanoic acid yog combustible nrog ib tug flash point ntawm kwv yees li 190.8 degree, thiab nyob rau hauv hluav taws kub tej yam kev mob, decomposition khoom uas muaj kev phom sij muaj xws li cov pa roj carbon monoxide thiab carbon dioxide.
2. Siv cov tshuaj tsuag dej, tshuaj qhuav hmoov, carbon dioxide, los yog cawv- ua npuas ncauj resistant los tua hluav taws nrog cov khoom; Tsis txhob siv lub dav hlau dej ncaj nraim li 2-(4-Methylphenyl) propanoic acid CAS 938-94-3 tuaj yeem tawg cov khoom tawg.
3. Cov neeg tua hluav taws yuav tsum hnav tus kheej- muaj cov cuab yeej ua pa hauv siab- thov, MSHA/NIOSH tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov hluav taws kub 2-(4-Methylphenyl) propanoic acid vim yog cov pa phem uas tsim los ntawm thermal decomposition .
4. Thaum lub sij hawm combustion, tej zaum yuav 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 los ntawm qhov chaw tiv thaiv, thiab muaj hluav taws kub los tiv thaiv ib puag ncig.
