Disposal

P501: Dispose of contents and empty containers in accordance with local, regional and federal regulations. EMERGENCY OVERVIEW IMMEDIATE CONCERNS: Styrene and vinyl toluene vapors are heavier than air and may travel along ground or may be moved by ventilation and ignited by sources at locations distant from material handling point.

Potential health effects

EYES: Contact may cause eye irritation. SKIN: Contact may cause skin irritation. SKIN ABSORPTION: May cause skin irritation. INGESTION: May be harmful if swallowed. INHALATION: May be harmful if inhaled. REPRODUCTIVE TOXICITY REPRODUCTIVE EFFECTS: Not known or believed to be a reproductive toxin.

Teratogenic Effects

Not known or believed to be teratogenic CARCINOGENICITY IARC 2B - Group 2B Possibly carcinogenic to humans MUTAGENICITY: Not known or believed to be mutagenic.

Principle Routes of Exposure

Inhalation, ingestion and through skin contact IRRITANCY: This product contains compounds that may cause skin or eye irritation. COMMENTS: Refer to Section 11 for detailed information on health effects and symptoms. AS SOLD the product is a polyester molding compound: It is a fibrous dough with a styrene and/or vinyl toluene odor; a polyester resin solution intimately mixed with one or more of a variety of inorganic filling materials, including fibrous glass. When fully compounded, the plastic resin binds the well-dispersed, embedded filling materials within the compound, which thus do not constitute an inhalation hazard. Styrene and vinyl toluene are irritants to skin, eyes and respiratory tract. Excessive exposure may cause stomach or intestinal upset, dizziness, drowsiness, fatigue or headache. Fibrous glass is a mechanical irritant to skin, eyes and nose. The IARC classified styrene in group 2B ( Possibly carcinogenic to humans). The IARC Concluded that there was no convincing evidence for carcinogenic action of styrene in animals based on the animal studies which existed at the time. Rather, the IARC 2B listing was based on data for styrene oxide, a metabolite of styrene. AS USED during polymerization (e.g., curing of the product during normal processing) some styrene and/or vinyl toluene vapors are expected to be released. During decomposition (e.g., overheating or burning of the product) normal products of combustion would be expected. Grinding or machining of cured molded material may create a dust that poses a respiratory hazard if inhaled.
