AMERADA HESS COP PO RATION <br /> MATERIAL SAFETY DATA SHEET <br /> Gasoline, All Grades MSDS No. 9950 <br /> SOLUBILITY(HZO): Non-oxygenated gasoline-negligible(<0.1% @ 77 OF). Gasoline with 15% <br /> MTBE-slight(0.1 -3% @ 77 OF); ethanol is readily soluble in water <br /> 10. STABILITY and REACTIVITY rev. Dec-94 <br /> STABILITY: Stable. Hazardous polymerization will not occur. <br /> CONDITIONS TO AVOID <br /> Avoid high temperatures, open flames, sparks, welding, smoking and other ignition sources <br /> INCOMPATIBLE MATERIALS <br /> Keep away from strong oxidizers. <br /> HAZARDOUS DECOMPOSITION PRODUCTS <br /> Carbon monoxide, carbon dioxide and non-combusted hydrocarbons (smoke). Contact with nitric and <br /> sulfuric acids will form nitrocresols that can decompose violently. <br /> 11. TOXICOLOGICAL PROPERTIES (rev. Dec-97 <br /> ACUTE TOXICITY <br /> Acute Dermal LD50 (rabbits): > 5 ml/kg Acute Oral LD50 (rat): 18.75 ml/kg <br /> Primary dermal irritation (rabbits): slightly irritating Draize eye irritation (rabbits): non-irritating <br /> Guinea pig sensitization: negative <br /> CHRONIC EFFECTS AND CARCINOGENICITY <br /> Carcinogenicity:OSHA: NO IARC: YES -2B NTP: NO ACGIH: YES (A3) <br /> IARC has determined that gasoline and gasoline exhaust are possibly carcinogenic in humans. Inhalation <br /> exposure to completely vaporized unleaded gasoline caused kidney cancers in male rats and liver tumors <br /> in female mice. The U.S. EPA has determined that the male kidney tumors are species-specific and are <br /> irrelevant for human health risk assessment. The significance of the tumors seen in female mice is not <br /> known. Exposure to light hydrocarbons in the same boiling range as this product has been associated in <br /> animal studies with effects to the central and peripheral nervous systems, liver, and kidneys. The <br /> significance of these animal models to predict similar human response to gasoline is uncertain. <br /> This product contains benzene. Human health studies indicate that prolonged and/or repeated <br /> overexposure to benzene may cause damage to the blood-forming system (particularly bone marrow), <br /> and serious blood disorders such as aplastic anemia and leukemia. Benzene is listed as a human <br /> carcinogen by the NTP, IARC, OSHA and ACGIH. <br /> This product may contain methyl tertiary butyl ether(MTBE ): animal and human health effects studies <br /> indicate that MTBE may cause eye, skin, and respiratory tract irritation, central nervous system <br /> depression and neurotoxicity. MTBE is classified as an animal carcinogen (A3) by the ACGIH. <br /> 12. ECOLOGICAL INFORMATION rev. Jan-04 <br /> Keep out of sewers, drainage areas and waterways. Report spills and releases, as applicable, under <br /> Federal and State regulations. If released, oxygenates such as ethers and alcohols will be expected to <br /> exhibit fairly high mobility in soil, and therefore may leach into groundwater. The API (www.api.org) <br /> provides a number of useful references addressing petroleum and oxygenate contamination of <br /> groundwater. <br /> 13. DISPOSAL CONSIDERATIONS rev. Dec-97 <br /> Consult federal, state and local waste regulations to determine appropriate disposal options. <br /> Revision Date: 01/08/04 Page 6 of 8 <br />
