Cia thiab ceev faj
1. D-Threonine yuav tsum tau muab khaws cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua nyob ib puag ncig, tiv thaiv lub teeb thiab noo noo; hmoov yog ruaj khov mus txog 3 xyoos ntawm -20℃lossis 2 xyoos ntawm 4 degree.
2. D-Threonine CAS 632-20-2 yog cais nrog GHS cov nqe lus txaus ntshai H315 (Ua rau tawv nqaij khaus), H319 (Ua rau qhov muag khaus), thiab H335 (Tej zaum yuav ua rau ua pa ua pa), nrog cov lus ceeb toom "Ceeb toom".
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg-cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb nrog sab- cov ntaub thaiv npog, thiab cov khaub ncaws tiv thaiv thaum tuav cov khoom no, ua kom muaj cua txaus hauv chaw ua haujlwm.
4. Khaws kom deb ntawm cov khoom siv tsis sib xws xws li muaj zog oxidizing tus neeg sawv cev; rau kev daws teeb meem, npaj aliquots thiab siv tsis pub dhau 1 lub hlis ntawm -20 degree, tsis txhob rov qab khov-thaw .
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, xyuas kom muaj qhov cua txaus, thiab hnav cov khoom tiv thaiv tus kheej tag nrho nrog rau cov tshuaj - hnab looj tes tiv thaiv, looj tsom iav dub, thiab lub tshuab ua pa uas tsim nyog thaum D-Threonine raug tso tawm.
2. Sau D-Threonine CAS 632-20-2 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 D-threonine los ntawm kev nkag mus rau hauv cov dej ntws los yog cov dej hauv 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-Threonine 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 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-Threonine CAS 632-20-2 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 D-Threonine vim muaj kev puas tsuaj rau cov roj cua 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.
