Ethylbenzene is a highly flammable hydrocarbon. 99% of the ethylbenzene produced is used to make styrene, which is in turn used to produce plastics. Ethylbenzene is also used as a solvent and in the production of asphalt, naptha, and fuels.
Appearance: Colorless liquid or gas.
Odor: Aromatic, gasoline.
Stationary: Chemical facilities that produce styrene.
Indoors: Cleaning products, solvents, carpet glues, varnishes, and paint.
Short-term (acute): Light exposure: Throat irritation, chest constriction, eye irritation, and dizziness.
Medium to high exposure: Central nervous system toxicity, pulmonary effects, and effects on the liver and kidneys.
Long-term (chronic): Ethylbenzene may have long term impacts on the blood. Its carcinogenicity and developmental effects are unknown.
