SECTION 3.0 JOB HAZARD ANALYSIS <br /> 3.1 GENERAL BACKGROUND <br /> The possible contaminant present on site is organics and lead from gasoline and/or diesel fuel. <br /> 3.2 WASTE DESCRIPTION <br /> Gasoline <br /> Gasoline can pose a significant health hazard as lead is a toxic metal. The organic lead compounds, <br /> tetraethyllead (TEL) and tetramethyllead (TML) are constituents of gasoline as antiknock compounds. <br /> Health problems associated with lead are headache, anxiety, insomnia, nervous excitation and minor <br /> gastrointestinal symptoms with a metallic taste in the mouth. Liquid alkyllead may penetrate the skin <br /> without producing appreciable local injury. However, the decomposition products (i.e., mono-, di-, <br /> and triethyllead compounds) in dust form may be inhaled and result in irritation of the upper <br /> respiratory tract and possibly paroxysmal sneezing. This dust, when in contact with moist skin or <br /> ocular membranes, may cause itching, burning, and transient redness. TEL itself is irritating to the <br /> eyes. The absorption of a sufficient quantity of TEL whether briefly at a high rate, or for prolonged <br /> periods at a lower rate, may give rise to a variety of symptoms which include mild anxiety, toxic <br /> delirium with hallucinations, delusions, convulsions, and acute toxic psychosis. Physical signs are not <br /> prominent; but bradychardia, hypotension, increased reflexes, tremor, and slight weight loss have <br /> been reported. When the interval between the termination of exposure and the onset of symptoms is <br /> short, an early fatal outcome may result.Exposure to TML may produce insomnia, bad dreams, <br /> restlessness, anxiousness; hypotension; nausea; aneroxia, delirium, mania, convulsions; coma. The <br /> points of attack for both TEL and TML are the central nervous system, cardiovascular system, <br /> kidneys and eyes. The acceptable method for monitoring lead contamination in humans is hair or <br /> blood analysis. The permissible level of lead in blood is 70 micrograms/milliliter. The airborne PEL is <br /> 0.1 mg/m3, and is determined by air monitoring and analysis by NIOSH Method 7300. Other <br /> constituents of gasoline can include but are not limited to benzene, toluene and xylene. Exposure to <br /> there compounds can cause nausea, dizziness, visual disturbances, narcosis and collapse. Chronic <br /> effects include central nervous system disorders, respiratory tract irritation, tearing, lassitude and <br /> immunological disorders. <br />
