i Material Safety Data Sheet Page of 8 skin contact with this product is not expected to have serious effects if it is washed from the skin. While skin cancer is unlikely to occur in human beings following use of this product, skin contact and breathing, of mists, vapors or dusts should be reduced to a minimum. This product contains naphthalene. GENERAL TOXICITY: Exposure to naphthalene has been reported to cause methemoglobinemia and/or hemolytic anemia, especially in humans deficient in the enzyme glucose-6-phosphate: II � g dehydrogenase. Laboratory animals given repeated oral doses of naphthalene have.developed cataracts. REPRODUCTIVE TOXICITY AND BIRTH DEFECTS: Naphthalene did not cause birth defects when administered orally to rabbits, rats, and mice during pregnancy, but slightly reduced litter size in mice at dose levels that were lethal to the pregnant females. Naphthalene has been reported to cross the human placenta. GENETIC TOXICITY: Naphthalene caused chromosome aberrations and sister chromatid exchanges in Chinese hamster ovary cells, but was not a mutagen in several other in-vitro tests.CARCINOGENICITY: In a study conducted by the National Toxicology Program (NT'), mice exposed to 10 or 30 ppm of naphthalene by inhalation daily for two years had chronic inflammation of the nose and lungs and increased incidences of metaplasia in those tissues. The incidence of benign lung tumors(alveolar/bronchiolar adenomas)was significantly increased in the high-dose female group but not in the male groups. In another two-year inhalation study conducted by NTP, exposure of rats to 10, 30, and 60 ppm naphthalene caused increases in the incidences of a variety of nonneoplastic lesions in the nose. Increases in nasal tumors were seen in both sexes, including olfactory neuroblastomas in females at 60 ppm and,adenomas of the respiratory epithelium in males at all exposure levels. The relevance of these effects to humans has not been established. No carcinogenic effect was reported in a 2-year feeding study in rats receiving naphthalene at 41 mglkglday. SECTION 12 ECOLOGICAL INFORMATION ECOTOXICITY The 48 hour(s) EC50 for water flea (Daphnia magna) is 20-210 mg/t. The 96 hour(s) LC50 for rainbow trout(Salmo gairdneri)is 21-210 mg/l. The 72 hour(s) EC50 for algae (Raphidocellus subcapitata) is 2.6-25 mgll. This material is expected to be toxic to aquatic organisms. ENVIRONMENTAL FATE On release to the environment the lighter components of diesel fuel will generally evaporate but depending on local environmental conditions(temperature, wind, mixing or wave action, soil type, etc.) the remainder may become dispersed in the water column or absorbed to soil or sediment. Diesel fuel would not be expected to be readily biodegradable. In a modified Strum test(OECD method 301B) approximately 40% biodegradation was recorded over 28 days. However, it has been shown that most hydrocarbon components of diesel fuel are degraded in soil in the presence of oxygen. Under anaerobic conditions, such as in anoxic sediments,'rates of biodegradation are negligible. SECTION 13 DISPOSAL CONSIDERATIONS Use material for its intended purpose or recycle if possible.This material, if it must be discarded, may meet the criteria of a hazardous waste as defined by US EPA under RCRA(40 CFR 261) or other State and local regulations. Measurement of certain physical properties and analysis for regulated components may be necessary to make a correct determination. If this material is classified as a hazardous waste, federal taw requires disposal at a licensed hazardous waste disposal facility. SECTION 1.4 TRANSPORT INFORMATION The description shown may not apply to all shipping situations. Consult 49CFR, or appropriate Dangerous Goods Regulations, for additional description requirements(e.g., technical name) and mode-specific or quantity-specific shipping requirements.
