MATERIAL SAFETY DATA SHEET Page: 3/4 Date Issued : Sep . 1, 2003 MSDS No. F-31231 8. EXPOSURE CONTROLS / PERSONAL PROTECTION Engineering Measures Ventilation :Not required under intended use. Exposure Limit Values OSHA-PEL (USA) :15mg/m3 (Total Dust) , 5mg/m3 (Respirable Dust) ACGIH-TLV (USA) :10mg/m3 (Total Dust) , 3mg/m3 (Respirable Dust) Personal Protective Equipment Respiratory Protection :Not required under intended use. Hand Protection :Not required under intended use. Eye Protection :Not required under intended use. Skin Protection :Not required under intended use. Other Protective Equipment :Use of a dust mask and goggles are recommended when handling a large quantity of toner or during long term exposure, as with any non-toxic dust. 9. PHYSICAL AND CHEMICAL PROPERTIES Appearance Physical State : Solid Ph Boiling / Melting Point Softening Point(°C ) Flash Point (°C ) Ignition Point(°C ) Explosion Properties Density (g/cm3) Solubility in Water Form: Powder :Not applicable :Not applicable :130°C(toner) :Not applicable :No data :No data :7 :Negligible Color: Black Odor: odorless 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) :LD50 > 2000mg/kg (Rats) Inhalation :LC50>5.14mg/L (Rats) 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. 90
