Loose Fill Bead Expandable Polymeric Beads

SECTION 2: Hazards identification

EMERGENCY OVERVIEW Solid, white or colored, rectangular-shaped beads (approx. 0.20”W x 0.18”Tk x 0.31”L). Slight hydrocarbon odor due to presence of pentane gas. WARNING STATEMENT Pentane vapor is extremely flammable. Flash fire could result from ignition of concentrated vapor. Highest concentration of vapor and greatest risk of flash fire is present when boxes of this EPS product are first opened. Pentane vapors are heavier than air and tend to collect in pockets or low areas near the floor or ground, but are readily dispersed by moving air.

Principle Routes of Exposure

EYE X SKIN X INHALATION X INGESTION __ Effects of Overexposure EYE: Fragments of resin bead resulting from rough or careless handling could cause abrasive irritation or injury. Concentrations of vapor from pentane gas blowing agent present in freshly opened boxes of EPS resin may cause irritation, experienced as discomfort, with excess tear production and reflexive blinking accompanied by some slight temporary development of eye redness. SKIN: Essentially non-irritating to the skin. Mechanical injuries only. INHALATION: Concentrations of vapor from pentane gas blowing agent present in freshly opened boxes of EPS resin may cause irritation of the nose and throat. Inhalation of concentrated vapors may also cause dizziness, drowsiness, euphoria, loss of coordination, disorientation, headache, nausea, and vomiting. In poorly ventilated areas or confined spaces, there may be risk of unconsciousness and asphyxiation. Prolonged or repeated overexposure to concentrated vapors may result in the absorption of potentially harmful amounts of material. INGESTION: Single dose oral toxicity is believed to be very low. No hazards anticipated from ingestion incidental to normal industrial exposure. If several mouthfuls or more are swallowed, abdominal discomfort, nausea, irritation from intestinal abrasion, and diarrhea may occur. SYSTEMIC (OTHER TARGET ORGANS): Only repeated exposure to concentrated vapors from the pentane gas blowing agent has been found to be harmful. Various studies have shown a possible association with pentane gas vapor exposure and the following: o Respiratory tract irritation o Central nervous system depression in high concentrations o Potential to sensitize heart muscle o Chronic (repeated, long-term) exposure may effect the liver
