Polyphenylene ether [CASRN 25134-01-4]/High impact polystyrene [CASRN 9003-55-8] and/or polystyrene [CASRN 9003-53-6] blend

SECTION 2: Hazards identification

EMERGENCY OVERVIEW: • Pellets with slight or no odor • Spilled material may create slipping hazard • Can burn in a fire creating dense, toxic smoke • Molten plastic can cause severe thermal burns • Fumes produced during melt processing may cause eye, skin, and respiratory tract irritation. Severe over-exposure may result in nausea, headache, chills, and fever. See below for additional effects. • Secondary operations, such as grinding, sanding, or sawing can produce dust which may present an explosion or respiratory hazard.

HMIS® ratings

Health: 0 Flammability: 1 Reactivity: 0 Skin Contact: Not a hazard with pellets during normal industrial use. Eye Contact: Resin particles, like other inert materials, are mechanically irritating to eyes. Inhalation: Pellet inhalation unlikely due to physical form. Processing fumes from PPE resin are not considered toxic. In acute inhalation tests, laboratory rats were exposed to processing fumes at concentrations exaggerating those that would likely occur in workplace situations. During the exposure periods (6 hour duration) signs of eye and nasal irritation were observed. These signs of irritation disappeared shortly after the animals were removed from the exposure chamber. No deaths or signs of toxicity were noted during the fume exposure period. There were no distinct or consistent treatment related tissue or organ changes noted in gross necropsies. Ingestion: Pellet ingestion unlikely due to physical form. Sensitization: No information available on this product

Medical Conditions Generally Aggravated by Exposure

MEDICAL RESTRICTIONS: There are no known health effects aggravated by exposure to this product. However, certain sensitive individuals and individuals with respiratory impairments may be affected by exposure to components in the processing vapors.
