Principle Routes of Exposure

Inhalation, Eye or Skin Contact Signs and Symptoms of Acute Irritation of eyes, skin & respiratory tract. Overexposure:

Medical Conditions Generally Aggravated by Exposure

Individuals with chronic respiratory disorders may be adversely affected by any fume or airborne particulate exposure. Sensitive individuals may be susceptible to allergic reaction from contact with skin, eyes, or respiratory tract.

Potential health effects

Eyes: Dust or particulate may cause irritation or scratch the surface of the eye. Fumes from heated material may be irritating. Skin: Though not expected to present significant skin irritation under normal conditions of use, prolonged exposure may cause slight irritation. Rubbing may cause irritation similar to sand or dust. Burns may occur from melted material. Ingestion: May cause choking if swallowed. Single dose oral toxicity is believed to be low. Inhalation: Exposures to dusts or fumes may cause irritation to the respiratory tract. Prolonged exposures at high concentrations could cause nausea, drowsiness, or headache. Carcinogenicity: NTP: No IARC: Carbon Black - Group 2B

Additional information

When the polymer is melted or heated to melt temperatures, decomposition of the peroxide may generate acetophenone, cumyl alcohol, and alpha-methylstyrene. These by-products will produce a sweet pungent odor detectable by human olfactory senses at 0.3 ppm. Acetophenone may accumulate in the headspace of shipping containers in quantities lower than the ACGIH recommended exposure limit of 10 mg/M3 (ACGIH TLV TWA).
