Kev kub ceev teb rau cov dej xau
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 D-2-Aminobutyric acid raug tso tawm.
2. Sau D-2-Aminobutyric acid CAS 2623-91-8 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav uas siv cov cuab yeej tsis muaj teeb, 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 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. D-2-Aminobutyric acid tsis raug cais raws li cov nplaim hluav taws kub heev tab sis tuaj yeem decompose nyob rau hauv hluav taws kub, emitting fumes lom xws li carbon monoxide, carbon dioxide, thiab nitrogen oxides (NOx).
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 D-2-Aminobutyric acid CAS 2623-91-8 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 D-2-Aminobutyric 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; muaj hluav taws kub los tiv thaiv ib puag ncig.
