유해성 요약	A skin, eye, and mucous membrane irritantHigh concentrations may cause lacrimation[HSDB] Oral LDLo (rat) = 5000 mg/kgEffects include general anesthesia[RTECS] An irritant[MSDSonline]The major hazards encountered in the use and handling of 1,3-diethylbenzene stem from its toxicologic properties and flammability. Exposure to this colorless liquid may occur from its use as a solventas an intermediate in the manufacture of divinylbenzeneand in powderless etching. Effects from exposure may include contact burns to the skin and eyes. In activities and situations where over-exposure may occur, wear a positive pressure self-contained breathing apparatus and protective clothing. If contact should occur, irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes, and wash exposed skin thoroughly with soap and water. 1,3-Diethylbenzene may be ignited by heat, sparks, or flames. Containers of this substance may expl ode in the heat of a fire. Also, its heavier-than-air vapor may travel to a source of ignition and flash back, or may accumulate to explosive concentrations in confined spaces such as sewers. For fires involving 1,3-diethylbenzene, extinguish with dry chemical, CO2, water spray, fog, or standard foam. Isolate the area for 1/2 mile in all directions if a tank, rail car, or tank truck is involved in the fire. For small spills of 1,3-diethylbenzene, take up with sand or other noncombustible absorbent and place into containers for later disposal. For large spills, use water spray to reduce vapor and dike far ahead of the spill for later disposal.
