2. Quinolinic acid CAS 89-00-9 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 ua rau ua pa ua pa), nrog cov teeb liab lo lus "Warning".
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 cov tshuaj muaj zog oxidizing, muaj zog acids, thiab cov hauv paus muaj zog los tiv thaiv decomposition; ntxuav kom huv si tom qab tuav.
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 tag nrho 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 Quinolinic acid tso tawm.
2. Sau Quinolinic acid CAS 89-00-9 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav 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 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. Quinolinic 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 Quinolinic acid CAS 89-00-9 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 Quinolinic acid vim muaj 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.
