<br />MATERIAL SAFETY DATA SHEET <br />Gasoline, All Grades MSDS No. 9950 <br /> <br />Revision Date: 09/25/2007 Page 6 of 9 <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 oC) <br />VAPOR PRESSURE: 6.4 - 15 RVP @ 100 oF (38 oC) (275-475 mm Hg @ 68 oF (20 oC) <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 oF). Gasoline with 15% <br />MTBE - slight (0.1 - 3% @ 77 oF); ethanol is readily soluble in water <br />10. STABILITY and REACTIVITY ) <br />STABILITY: Stable. Hazardous polymerization will not occur. <br /> <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.
