E E: ]S <br /> MATERIAL SAFETY DATA SHEET <br /> Gasoline, All Grades MSDs No. 9950 <br /> ODOR <br /> A strong, characteristic aromatic hydrocarbon odor. Oxygenated gasoline with MTBE and/or TAME may <br /> have a sweet, ether-like odor and is detectable at a lower concentration than non-oxygenated gasoline. <br /> ODOR THRESHOLD <br /> Odor Detection Odor Recognition <br /> Non-oxygenated gasoline: 0.5-0.6 ppm 0.8- 1.1 ppm <br /> Gasoline with 15% MTBE: 0.2-0.3 ppm 0.4-0.7 ppm <br /> Gasoline with 15%TAME: 0.1 ppm 0.2 ppm <br /> BASIC PHYSICAL PROPERTIES <br /> BOILING RANGE: 85 to 437 OF (39 to 200 °C) <br /> VAPOR PRESSURE: 6.4- 15 RVP @ 100 OF (38'C)(275-475 mm Hg @ 68 OF (20 °C) <br /> VAPOR DENSITY(air= 1): AP 3 to 4 <br /> SPECIFIC GRAVITY(H2O= 1): 0.70-0.78 <br /> EVAPORATION RATE: 10-11 (n-butyl acetate= 1) <br /> PERCENT VOLATILES: 100% <br /> SOLUBILITY(H2O): Non-oxygenated gasoline-negligible(<0.1%@ 77°F). Gasoline with 15% <br /> MTBE-slight(0.1 -3% @ 77°F); ethanol is readily soluble in water <br /> 10. STABILITY and REACTIVITY <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 <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 /> Revision Date: 09/25/2007 Page 6 of 9 <br />
