2. Sau Tetrahydropyran-4-carbaldehyde CAS 50675-18-8 siv cov cuab yeej uas tsis muaj teeb meem los ntawm kev nqus nrog cov ntaub ntawv tsis zoo xws li xuab zeb, diatomite, lossis universal binders, thiab muab tso rau hauv cov thawv kaw kom haum rau kev pov tseg.
3. Tsis txhob tsim cov vapors lossis pos huab thaum ntxuav kom tiv thaiv kev ua pa; decontaminate nto siv txoj kev tsim nyog; 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. Tshem tawm cov khoom pov tseg raws li cov khoom pov tseg uas muaj kev phom sij raws li hauv zos, xeev, thiab tsoomfwv ib puag ncig kev tswj hwm los ntawm kev tso cai tshuaj lom neeg puas tsuaj los yog kev tswj cov incineration, ceeb toom tias cov khoom raug suav tias tsis yog - phom sij rau kev thauj mus los hauv huab cua thiab hauv av.
Kev tiv thaiv hluav taws
1. Tetrahydropyran-4-carbaldehyde is a combustible liquid with a flash point ranging from >23℃rau 65 degree, thiab kub taw tes ntawm 176.9℃ntawm 760 mmHg; Nyob rau hauv cov xwm txheej hluav taws kub, cov khoom tsim kev puas tsuaj muaj xws li cov pa phem ntawm cov pa roj carbon monoxide, carbon dioxide, thiab cov pa roj carbon monoxide.
2. Siv cov hmoov qhuav qhuav, carbon dioxide, lossis cawv- ua npuas ncauj los tua hluav taws uas cuam tshuam nrog cov khoom; Tsis txhob siv lub dav hlau dej ncaj qha vim nws yuav tawg cov khoom tawg.
3. Cov neeg tua hluav taws Tetrahydropyran-4-carbaldehyde CAS 50675-18-8 yuav tsum hnav lub tshuab ua pa ntawm tus kheej hauv qhov kev thov siab, MSHA/NIOSH tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov kub kub Tetrahydropyran-4-carbaldehyde los ntawm kev ua kom muaj cua sov.
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 cov hluav taws kub los tiv thaiv ib puag ncig thiab muaj kuab paug.
