3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- 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 tshuaj no. Siv qhov cua kom txaus lossis tso pa hauv zos kom tsis txhob nqus pa. Nyob rau hauv cov ntaub ntawv ntawm qhov cua tsis txaus, hnav tiv thaiv ua pa haum.
4. Khaws 4-(2-Methylpropyl)acetophenone CAS 38861-78-8 kom deb ntawm cov ntaub ntawv tsis sib xws xws li cov oxidizing muaj zog thiab cov hauv paus muaj zog los tiv thaiv kev puas tsuaj. Lub compound muaj ib tug flash point ntawm 54℃(kaw khob) thiab yog cais nrog cov nqe lus pheej hmoo R10 (Flammable). Khaws cais los ntawm qhov hluav taws kub.

1. Tshem tawm ntawm qhov chaw nchuav, tshem tawm txhua qhov hluav taws kub, ua kom muaj cua txaus, thiab hnav cov cuab yeej tiv thaiv tus kheej nrog rau cov tshuaj lom neeg - hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab ua pa tsim nyog thaum ntxuav.
2. Sau 4-(2-Methylpropyl)acetophenone CAS 38861-78-8 los ntawm absorbing nrog inert absorbent cov ntaub ntawv xws li xuab zeb, vermiculite, los yog diatomaceous lub ntiaj teb siv cov cuab yeej uas tsis yog-tshuaj, thiab muab tso rau hauv lub thawv kaw tsim nyog rau pov tseg.
3. Tsis txhob tsim cov txaws lossis pos huab thaum ntxuav kom tsis txhob raug rau ntawm daim tawv nqaij thiab qhov muag; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov kav dej, cov kav dej, lossis cov chav dej vim yog ib puag ncig toxicity (H411).
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig los ntawm cov chaw pov tseg tshuaj muaj ntawv tso cai. Cov khoom muaj qhov ntsuas WGK lub teb chaws Yelemees ntawm 3 (muaj kev phom sij heev rau dej).

1. 4-(2-Methylpropyl)acetophenone yog cais raws li nplaim taws nrog lub teeb nyem ntawm 54℃(kaw khob). Nyob rau hauv cov xwm txheej hluav taws kub, lub compound decomposes tawm cov pa phem xws li carbon monoxide thiab carbon dioxide.
2. Siv cov hmoov qhuav qhuav, carbon dioxide, cawv- ua npuas dej tiv taus, los yog tshuaj tsuag dej los tua hluav taws uas cuam tshuam nrog cov khoom. Tsis txhob siv lub dav hlau dej ncaj nraim li 4-(2-Methylpropyl)acetophenone CAS 38861-78-8 tuaj yeem tawg cov khoom tawg.
3. Cov neeg tua hluav taws yuav tsum hnav tus kheej- muaj cov cuab yeej ua pa (SCBA) hauv siab- thov, NIOSH- tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov hluav taws kub uas muaj cov khoom sib xyaw no vim muaj cov pa phem uas tsim tawm thaum lub sij hawm 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. Cov khoom lag luam muaj qhov kub ntawm 268.8℃ntawm 760 mmHg thiab vapor siab ntawm 0.75 Pa ntawm 20 degree.
