1. Tshem tawm ntawm qhov chaw nchuav, ua kom muaj cua txaus, thiab hnav cov khoom tiv thaiv tus kheej nrog rau cov tshuaj lom neeg - cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab ua pa uas tsim nyog thaum 5-Methyl-2-thiophenecarboxylic acid raug tso tawm.
2. Sau 5-Methyl-2-thiophenecarboxylic acid CAS 1918-79-2 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav uas siv cov cuab yeej tsis ua kom tawg, 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 chav dej.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv ib puag ncig kev tswj hwm los ntawm kev tso cai los ntawm kev puas tsuaj los yog kev tswj hwm incineration.
Kev tiv thaiv hluav taws
1. 5-Methyl-2-thiophenecarboxylic acid tsis raug cais raws li cov nplaim hluav taws kub heev tab sis tuaj yeem tawg tau nyob rau hauv qhov hluav taws kub, tawm cov pa phem xws li carbon monoxide, carbon dioxide, thiab sulfur oxides.
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 qha raws li 5-Methyl-2-thiophenecarboxylic acid CAS 1918-79-2 tuaj yeem tawg cov khoom tawg.
3. Cov neeg tua hluav taws yuav tsum hnav nws 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 5-Methyl-2-thiophenecarboxylic acid vim muaj kev puas tsuaj rau cov pa roj uas tsim los ntawm thermal decomposition .
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; muaj hluav taws kub los tiv thaiv ib puag ncig.
