Tsis txhob nqus cov vapors lossis pos huab, ua kom muaj cua txaus hauv thaj chaw ua haujlwm (xws li lub fume hood), ntxuav kom huv si tom qab tuav, thiab ua raws li cov lus qhia ceev faj P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv) thiab P305+P351+P338 (yog tias nyob hauv qhov muag) ceev faj:
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav, xyuas kom muaj qhov cua txaus, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab hnav cov khoom tiv thaiv tus kheej nrog rau cov tshuaj lom neeg - hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab kev tiv thaiv ua pa tsim nyog thaum tetrahydro-4-pyranol raug tso tawm.
2. Ntim thiab sau Tetrahydro-4-pyranol CAS 2081-44-9 siv lub tshuab nqus tsev tiv thaiv hluav taws xob lossis los ntawm kev txhuam ntub dej, lossis npog nrog cov txiv qaub qhuav lossis dej qab zib tshauv, siv cov cuab yeej tsis muaj teeb meem, thiab muab tso rau hauv cov thawv kaw tsim nyog rau kev pov tseg.
3. Tsis txhob tsim cov vapors lossis pos huab thaum lub sij hawm ntxuav, ceev faj ntawm cov vapors accumulating los ua explosive concentrations nyob rau hauv tsawg qhov chaw, thiab tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov dej ntws los yog cov dej hauv chav kawm vim tej zaum yuav muaj kev phom sij.
4. Tshem tawm cov khoom siv pov tseg raws li hauv zos, xeev, thiab tsoomfwv cov cai tswjfwm ib puag ncig, nyiam dua los ntawm kev tso cai tshuaj lom neeg puas tsuaj lossis tswj kev tua hluav taws hauv cov tshuaj incinerator uas nruab nrog lub tshuab hluav taws xob tom qab thiab tshuab ntxhua khaub ncaws.
Kev tiv thaiv hluav taws
1. Tetrahydro-4-pyranol yog cov kua hluav taws xob uas muaj lub teeb ci ntawm 88℃(190℃F) thiab NFPA qhov ntsuas hluav taws kub ntawm 1, yuav tsum tau ua kom muaj cua sov ntau ua ntej ignition, tab sis tej zaum yuav tawm cov pa phem xws li carbon oxides nyob rau hauv hluav taws kub.
2. Siv dej cawv- ua npuas dej tiv taus, cov hmoov tshuaj qhuav, cov pa roj carbon dioxide, lossis cov tshuaj tsuag dej los tua hluav taws uas cuam tshuam nrog cov khoom, zam cov dej ntws ncaj qha uas yuav kis tau hluav taws.
3. Cov neeg tua hluav taws Tetrahydro-4-pyranol CAS 2081-44-9 yuav tsum hnav cov cuab yeej ua pa ntawm tus kheej thiab cov iav tiv thaiv tag nrho thaum tuav cov hluav taws kub tetrahydro-4-pyranol vim muaj cov pa phem xws li carbon monoxide thiab carbon dioxide uas tsim los ntawm thermal decomposition.
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, thiab muaj cov hluav taws kub los tiv thaiv ib puag ncig.
