724130- Green Coke Issue date: 12-Feb-2019 Page 5/7 Status: FiN,. Skin Corrosion/Irritation: Prolonged or repeated contact with dusts may be abrasive and mildly irritating to the skin. Serious Eye Damage/Irritation: Dusts may be abrasive and irritating to the eyes. Skin Sensitization: No information available. Respiratory Sensitization: No information available. Specific Target Organ Toxicity (Single Exposure): Not expected to cause organ effects from single exposure. Specific Target Organ Toxicity (Repeated Exposure): Not expected to cause organ effects from repeated exposure. Repeated exposure of rats to 10 and 30 mg/m3 petroleum coke dust for two years resulted in signs of lung injury including fibrosis (scarring of lung tissue). Similar exposures in monkeys caused no significant lung effects. Carcinogenicity: Not expected to cause cancer. Lifetime inhalation and dermal application studies in mice of petroleum coke did not demonstrate carcinogenicity. Germ Cell Mutagenicity: Inadequate information available. Reproductive Toxicity: Not expected to cause reproductive toxicity. A reproductive/developmental toxicity screening study of green coke in rats did not demonstrate effects on fertility or reproductive performance at concentrations of 30, 100, and 300 mg/m3. Other Comments: This material may contain varying concentrations of polycyclic aromatic hydrocarbons (PAHs) which have been known to produce a phototoxic reaction when contaminated skin is exposed to sunlight. The effect is similar in appearance to an exaggerated sunburn, and is temporary in duration if exposure is discontinued. Continued exposure to sunlight can result in more serious skin problems including pigmentation (discoloration), skin eruptions (pimples), and possible skin cancers. SECTION 12: Ecological information GHS Classification: No classified hazards Toxicity: Acute toxicity studies on samples of petroleum coke show that acute aquatic toxicity values are greater than 1000 mg/L for invertebrates, algae and fish. Elemental carbon, which is the principal constituent of petroleum cokes, poses no risk to aquatic organisms. Residual hydrocarbon concentrations are very low and have a high molecular weight. Such hydrocarbons are too water insoluble to cause acute aquatic toxicity. Therefore petroleum coke is unlikely to pose a long-term hazard to the environment. Persistence and Degradability: Petroleum cokes are not expected to meet the criteria for ready degradability. Elemental carbon and hence, petroleum coke is a persistent material. Also, any associated very high molecular weight hydrocarbons would only be very slowly biodegraded. Bioaccumulative Potential: Elemental carbon is not known to bioaccumulate. The very high molecular weight of any associated hydrocarbons, combined with their very low water solubilities, indicate that they are not likely to bioaccumulate. The trace hydrocarbon components of petroleum cokes have values for log Kow greater than 6. Mobility in Soil: The hydrocarbon components of petroleum cokes have negligible vapor pressures at ambient temperature and volatility is not a significant fate process for these substances. Other adverse effects: None anticipated. SECTION 13: Disposal considerations The generator of a waste is always responsible for making proper hazardous waste determinations and needs to consider state and local requirements in addition to federal regulations. This material, if discarded as produced, would not be a federally regulated RCRA "listed" hazardous waste and is not believed to exhibit characteristics of hazardous waste. See Sections 7 and 8 for information on handling, storage and personal protection and Section 9 for physical/chemical properties. It's possible that the material as produced contains constituents which are not required to be listed in the SDS but could affect the hazardous waste determination. Additionally, use which results in chemical or physical change of this material could subject it to regulation as a hazardous waste. Container contents should be completely used and containers should be emptied prior to discard.
