1,3-Butadiene

SECTION 2: Hazards identification

EMERGENCY OVERVIEW Irritant to eyes and skin. Inhalation of moderate concentrations may cause dizziness, drowsiness, blurring of vision, and nausea. At higher concentrations, product becomes a simple asphyxiant. An anesthetic effect that can cause respiratory paralysis and death. Probable human carcinogen. Highly flammable.

Principle Routes of Exposure

Skin Contact Yes Skin Absorption No Eye Contact Yes Inhalation Yes Ingestion Yes Eye Effects: Vapors may be irritating to the eyes. Skin Effects Butadiene is irritating to mucous membranes and the skin. Due to its rapid rate of evaporation, it can cause tissue freezing or frostbite on dermal contact. Frostbite effects appear as a change in color of the skin to gray or white, possibly followed by blistering. May cause skin rash. Ingestion Effects Since product is a gas at room temperature, ingestion is unlikely. Contact with liquid product may cause freezing of tissue and should be treated as frostbite. Consult a physician for treatment. Inhalation Effects In moderate concentrations, butadiene may cause dizziness, drowsiness, blurring of vision and nausea. In higher concentrations, it is an asphyxiant, an anesthetic, and can cause respiratory paralysis and death. Repeated Exposures have given no indication of cumulative action.
