SECTION 2: Hazards identification

Principle Routes of Exposure

Inhalation of processing emissions during periods of elevated temperature. Eye: Vapors or fumes emitted during processes involving elevated temperatures may cause eye irritation. Dust resulting from the handling of powder may be irritating to the eyes. Skin Contact: Vapors or fumes emitted during processes involving elevated temperatures may cause skin irritation. Dust resulting from the handling of powder may be irritating to the skin. Skin Absorption: This material is initially a dry solid pellet; no absorption is likely to occur in its initial form. Vapors or fumes emitted during processes involving elevated temperatures may absorb through the skin at low levels. Ingestion: Slightly toxic by ingestion. Dust may become airborne during handling, resulting in the potential for incidental ingestion. Vapors or fumes emitted during processes involving elevated temperature may be ingested at low levels. Adequate ventilation should be provided. Inhalation: Dust may become airborne during handling, resulting in potential inhalation exposure. Vapors or fumes emitted during processes involving elevated temperatures may be inhaled if not adequately ventilated.

2.1 Classification of the substance or mixture

Acute Effects: Dust associated with the handling of masterbatch powder as well as vapors or fumes liberated from compound at high temperatures may be irritating to the eyes, skin and respiratory tract if not adequately ventilated.

Potential chronic health

Chronic exposure to vapors or fumes from thermally decomposed or decomposing plastics or plastics that are otherwise exposed to elevated temperatures or are processed at elevated temperatures may cause an asthma- like syndrome due to the inhalation of processing vapors or fumes. The onset of irritation may be delayed for several hours. Vapors or fumes may accumulate within the facility during normal operating procedures that involve elevated temperatures. Exposure to these elevated concentrations, if not adequately ventilated, may have significant health effects. Carcinogenic: IARC has determined that there is inadequate evidence of carcinogenicity of a masterbatch resin in both animals and humans. Quasar (ROHS, REACH,Prop 65 Compliant) Additionally, the low levels of additives used in masterbatch pellet compounds are also bound in the polymer matrix and to the best of the supplier’s knowledge; do not present a significant health risk.
