Skin Irritation: For a 4-hour exposure, the Primary Irritation Index(PII) in rabbits is: 4.8/8.0. CSkin Sensitization: This material did not cause skin sensitization reactions in a Buehler guinea pig test. ute Dermal Toxicity: LD50: >3.75g/kg (rabbit). Acute Oral Toxicity: LD50: >5 ml/kg (rat) Iute Inhalation Toxicity: 4 hour(s) LD50: >20000mg/m3 (rat). ubchronic Effects: Exposure of rats for 13 weeks (6 hr/day for 5 days/week)to the light ends of gasoline (up to 20,000 mg/m3) resulted in minimal responses of toxicity. There were no indications of neurotoxicity based morphological, functional and biochemical indices. There was also no evidence of immunotoxicity in the rats. However, when rats were exposed to gasoline vapor containing ithanol up to 20,000 mg/m3 there was evidence of both humoral immune suppression and mild astrogliosis. Reproduction and Birth efects: Exposure of rats to the light ends of gasoline at up to 20,000 mg/m3 had generally no impact upon reproductive abilities and did not cause birth defects. wenetic Toxicity: Gasoline was not mutagenic, with or without activation, in the Ames assay(Salmonella typhimurium), Saccharamyces erevisesae, or mouse lymphoma assays. In addition, point mutations were not induced in human lymphocytes. Gasoline was not mutagenic when tested in the mouse dominant lethal assay. Administration of gasoline to rats did not cause chromosomal aberrations in their bone marrow cells. Inhalation exposure of rats to the light ends of gasoline caused increased sister chromatid exchange in their eripheral white blood cells but did not cause an increase in micronucleated red blood cells in their bone marrow. DITIONAL TOXICOLOGY INFORMATION: Gasolines are highly volatile and can produce significant concentrations of vapor at ambient temperatures. Gasoline vapor is heavier than rit and at high concentrations may accumulate in confined spaces to present both safety and heath hazards. When vapor exposures are ow, or short duration and infrequent, such as during refueling and tanker loading/unloading, neither total hydrocarbon nor components such as benzene are likely to result in any adverse health effects. In situations such as accidents or spills where exposure to gasoline vapor is potentially high, attention should be paid to potential toxic effects of specific components. Information about specific components in gasoline can be found in Sections 2, 8 and 15 of this MSDS. More detailed information on the health hazard of specific gasoline omponents can be obtained calling the Chevron Emergency Information Center (see Section 1 for phone numbers).
