SECTION 3.0 JOB HAZARD ANALYSIS 3.1 GENERAL BACKGROUND ` The possible contaminant present on site is organics and lead from gasoline and/or diesel fuel. 3.2 CONTAMINANT DESCRIPTION Gasoline Gasoline can pose a significant health hazard as lead is a toxic metal. . The organic lead compounds, tetraethyllead (TEL) and tetramethyllead (TML) are constituents of gasoline as antiknock compounds. Health problems associated with lead are headache, anxiety, insomnia, nervous excitation and minor gastrointestinal symptoms with a metallic taste.in the mouth. Liquid alkyilead may penetrate the skin without producing appreciable local injury. However, the decomposition products (i.e., mono-, di-, and triethyllead compounds) in dust form may be inhaled . and result in irritation of the upper respiratory tract and possibly paroxysmal sneezing. This dust, when in contact with moist skin or ocular membranes, may cause.itching, burning, and transient redness. TEL itself is irritating to the eyes. The absorption of a sufficient quantity of TEL whether briefly at a high rate, or for prolonged periods at a lower rate, may give rise to a variety of symptoms which include mild anxiety, toxic delirium with hallucinations, delusions, convulsions, and acute toxic psychosis. Physical signs are not prominent; but bradychardia, hypotension, increased reflexes, tremor, and slight weight loss have been reported.
