Cov tsos mob lom los ntawm kev nqus tau siab yog xeev siab, ntuav, thiab cov tshuaj loog dav dav. Hauv tib neeg, cov tshuaj lom neeg tuaj yeem hnov qab txog qib 3000-4000 ppm.Cov tshuaj lom ntawm qhov ncauj thiab dermal hauv cov tsiaj kuaj tsis tshua muaj. Cov teebmeem yog kev nyuaj siab me ntsis ntawm lub hauv nruab nrab lub paj hlwb thiab hloov me ntsis hauv daim siab thiab lub raum. Txoj kev rov qab tau sai. Irritant ua rau ntawm daim tawv nqaij thiab ob lub qhov muag ntawm rabbits yog tsawg LC50 tus nqi (rats): 7000 ppm / 6 h LD50 tus nqi (rats): 5660 mg / kg.
Hluav Taws Xob	FLAMMABLE. Flashback raws vapor txoj kev yuav tshwm sim. Vapor yuav tawg yog tias ignited nyob rau hauv ib qho chaw nyob.
Flammability thiab Explosibility	Flamable
Kev ruaj ntseg Profile	Muaj tshuaj lom los ntawm txoj hauv kev. Mob me me los ntawm kev noj, nqus pa, thiab kev sib cuag ntawm daim tawv nqaij. Tib neeg cov teebmeem los ntawm kev nqus pa: kev siv tshuaj loog, xeev siab. Ib daim tawv nqaij thiab qhov muag irritant. Ib qho kev sim teratogen. Ntau cov glycol ethers muaj kev phom sij rau tib neeg kev ua me nyuam. Qhov phom sij txaus ntshai heev thaum raug tshav kub lossis nplaim taws; tuaj yeem cuam tshuam nrog oxidizing cov ntaub ntawv. Txhawm rau tua hluav taws, siv ua npuas ncauj, CO2, tshuaj qhuav. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes.

Kev xa khoom	UN3092 1-Methoxy-2-propanol, Hazard Class: 3; Cov ntawv lo: 3-Flammable kua.
Kev tshuaj ntsuam toxicity	Tiv tauj irritates daim tawv nqaij, qhov muag thiab mucous daim nyias nyias. Kev raug vapors ntev yuav ua rau hnoos, ua tsis taus pa, kiv taub hau thiab intoxication. Vapors hnyav dua li huab cua. Siv los ua cov kuab tshuaj thiab ua cov tshuaj tiv thaiv kab mob. Qhov ncauj LD50 ntawm nas yog 6.6g / kg. Cov tawv nqaij khaus tsis pom tseeb, tab sis cov tshuaj lom neeg tuaj yeem nqus tau los ntawm daim tawv nqaij. Lub ntsiab manifestations ntawm tsiaj lom yog inhibition thiab tsis tiav tshuaj loog. Ib nrab ntawm cov nas tuag thaum lawv raug rau chav dej ntawm 40.18g / m3 rau 5 ~ 6 teev. qhov cuam tshuam ntawm 1-methoxypropanol-2 (MEP) rau qhov stimulation ntawm inflammatory teb nyob rau hauv tib neeg ua pa mucosa, peb nthuav tawm 22 thawj cell kab lis kev cai ntawm qhov ntswg ua pa epithelia ntawm cov neeg noj qab haus huv rau MEP concentrations ntawm lub German MAK-tus nqi (100ppm) thiab mus rau 10-fold concentration (1000ppm).
Qhov zoo	1-Methoxy-2-propanol tau siv los ua cov khoom siv tshuaj tiv thaiv kab mob, feem ntau hauv cov tshuab cua txias thiab hauv qee lub cav diesel hnyav. Vim hais tias ib qho azeotrope yog tsim los ntawm 1-methoxy-2-propanol thiab dej, kev tiv thaiv khov kuj muaj nyob rau hauv vapor theem hauv ebullient cooling applications. Ntawm qhov tod tes, 1-methoxy-2-propanol yog volatile ntau dua thiab yooj yim dua tshem tawm nrog rau cov dej vapor los ntawm lub crankcase vent system. 1-Methoxy-2-propanol kuj tseem khaws cov hlau qis dua li cov khoom siv sib piv glycolbased coolants. Qhov no yog qhov kom zoo dua nyob rau hauv lub tshuab rotary.
Kev tsis sib haum xeeb	Vapor tuaj yeem tsim cov khoom tawg nrog cua. Tsis sib haum nrog oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, thiab lwm yam); kev sib cuag tej zaum yuav ua rau hluav taws kub los yog tawg. Khaws kom deb ntawm cov ntaub ntawv alkaline, muaj zog hauv paus, muaj zog acids, oxoacids, epoxides, acid chlorides, acid anhydrides, isocya-nates, aluminium, thiab tooj liab. Hygroscopic (piv txwv li, absorbs noo noo los ntawm huab cua). Tej zaum yuav maj mam tsim reactive peroxides thaum lub sij hawm ntev cia los yog raug rau huab cua thiab lub teeb.
Pov tseg pov tseg	Dissolve los yog sib tov cov khoom nrog ib tug combustible solvent thiab hlawv nyob rau hauv ib tug chemical incinerator nruab nrog ib tug afterburner thiab scrubber. Tag nrho tsoom fwv teb chaws, xeev, thiab cheeb tsam ib puag ncig cov cai yuav tsum tau ua raws li.
