10. STABILITY AND REACTIVITY Stability : Stable Hazardous Reactions : Dust explosion, like most finely divided organic powders. Conditions to avoid : Electric discharge, throwing into fire. Materials to avoid : Oxidizing Materials Hazardous Decomposition Products : CO, CO2 and NOx Further Information : None 11. TOXICOLOGICAL INFORMATION Acute Toxicity Ingestion(oral) : LDL50>2500mg/kg (Rats) Dermal : No Data Inhalation : No Data Eye irritation : Not an irritant (Rabbits) Skin irritation : Not an irritant (Rabbits) Skin sensitizer : No Data Mutagenicity : Negative (Ames Test) Carcinogenicity : In 1996 the IARC reevaluated carbon black as a Group 2B carcinogen (possible human carcinogen). This classification is given to chemicals for which there is inadequate human evidence, but sufficient animal evidence on which to base an opinion of carcinogenicity. The classification is based upon the development of lung tumors in rats receiving chronic inhalation exposures to free carbon black at levels that induce particle overload of the lung. Studies performed in animal models other than rats did not show any association between carbon black and lung tumors. Moreover, a two-year cancer bioassay using a typical toner preparation containing carbon black demonstrated no association between toner exposure and tumor development in rats. Chronic Effect : In a study in rats of chronic inhalation exposure to a typical toner, a mild to moderate degree of lung fibrosis was observed in 92% of the rats in the high concentration (16mg/m3) exposure group, and a minimal to mild degree of fibrosis was noted in 22% of the animals in the middle (4mg/m3) exposure group, but no pulmonary change was reported in the lowest (1mg/m3) exposure group, the most relevant level to potential human exposures. 12. ECOLOGICAL INFORMATION No data are available. 13. DISPOSAL CONSIDERATION Waste from residues : Waste material may be dumped or incinerated under conditions which meet all federal, state and local environmental regulations. Contaminated Packaging : Waste may be disposed or incinerated under conditions which meet all federal, state and local environmental regulations. 14. TRANSPORT INFORMATION UN Classification : Land DOT (USA) : Sea IMDG : Air ICAO-TI : None None None None 123
