Health Hazard	Cov tshuaj lom neeg mob hnyav los ntawm kev raug rau cov vapors ntawm MIPK yog narcosis thiab khaus ntawm lub qhov muag, daim tawv nqaij, thiab cov kab mob ua pa.Nyob rau hauv cov luav cov tsos mob ntawm 100 mg fora 24- teev raug mob me me hauv qhov muag, thaum 500 mg yog nruab nrab. ntawm daim tawv nqaij. Cov ntaub ntawv toxicity ntawm cov tshuaj no tsis tshua muaj heev. Feem ntau, nws cov tshuaj toxicity tsawg thiab cov tsos mob narcosis nyob rau hauv tib neeg tej zaum yuav hnov tsuas yog nyob rau hauv heev concentrations. Hauv guinea npua exposureto 5000 ppm ua rau coma.
Hluav Taws Xob	Kev phom sij tshwj xeeb ntawm combustion khoom: Acrid pa luam yeeb thiab pa taws
Flammability thiab Explosibility	Cov nplaim taws heev
Kev ruaj ntseg Profile	Tshuaj lom los ntawm kev noj tshuaj. Mob me me los ntawm kev nqus pa thiab kev sib cuag ntawm daim tawv nqaij. Cov ntaub ntawv hloov pauv tau tshaj tawm. Ib daim tawv nqaij thiab qhov muag irritant. Flammable thaum raug tshav kub los yog nplaim taws; tuaj yeem cuam tshuam nrog cov khoom siv oxidizing. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes.
Ntxim yuav nphav raug	Cov ketone no yog siv los ua cov kuab tshuaj rau nitrocellulose lacquers.
Kev pab thawj zaug	Yog hais tias cov tshuaj no nkag mus rau hauv lub qhov muag, tshem tawm ib qho kev sib cuag lo ntsiab muag ib zaug thiab irrigate tam sim ntawd rau tsawg kawg yog 15 feeb, qee zaus nqa lub hau sab sauv thiab qis dua. Nrhiav kev kho mob tam sim ntawd. Yog tias cov tshuaj no kis rau ntawm daim tawv nqaij, tshem tawm cov khaub ncaws tsis huv thiab ntxuav tam sim nrog xab npum thiab dej. Nrhiav kev kho mob tam sim ntawd. Yog tias cov tshuaj no tau nqus tau lawm, tshem tawm ntawm qhov raug, pib ua pa cawm siav (siv kev ceev faj thoob ntiaj teb, suav nrog daim npog qhov ncauj resuscitation) yog tias ua pa tau nres thiab CPR yog tias lub plawv nres. Hloov tam sim ntawd mus rau qhov chaw kho mob. Thaum cov tshuaj no tau nqos lawm, mus ntsib kws kho mob. Muab dej ntau thiab ua kom ntuav. Tsis txhob ua rau tus neeg tsis nco qab ntuav.
khaws cia	Xim Code-Red: Flammability Hazard: Khaws cia rau hauv qhov chaw cia cov kua hluav taws xob los yog lub txee tso cai kom deb ntawm qhov hluav taws kub thiab cov khoom siv corrosive thiab reactive.Ua ntej ua hauj lwm nrog cov tshuaj no koj yuav tsum tau kawm txog nws txoj kev tuav thiab khaws cia. Ua ntej nkag mus rau hauv qhov chaw kaw qhov chaw uas cov tshuaj no tuaj yeem tshwm sim, xyuas kom paub tseeb tias tsis muaj cov khoom tawg. Khaws cov thawv kaw nruj nreem rau hauv qhov chaw txias, qhov cua zoo kom deb ntawm aldehydes. Qhov chaw ntawm qhov hluav taws kub, xws li haus luam yeeb thiab qhib nplaim taws, txwv tsis pub qhov twg methyl isopropylketone siv, tuav, lossis khaws cia rau hauv ib qho uas yuav ua rau muaj hluav taws kub lossis tawg. Siv cov cuab yeej thiab cov khoom siv tsis muaj teeb meem nkaus xwb, tshwj xeeb tshaj yog thaum qhib thiab kaw cov ntim ntawm methyl isopropyl ketone. Txhua qhov chaw siv methyl isopropyl ketone siv, tuav, tsim, lossis khaws cia, siv cov khoom siv hluav taws xob tawg thiab cov khoom siv.
