n <br /> 5.0 HAZARD ANALYSIS <br /> Potential chemical, physical and general safety hazards during <br /> the site investigation activities at the Site include the <br /> following: <br /> • Chemical hazards <br /> • respiratory (exposure tc volatile organic compounds <br /> [VOCs] ) <br /> dermal (contact with petroleum products) <br /> 6 <br /> • Physical hazards <br /> • excavation instability <br /> • noise <br /> • electric shock <br /> • heavy equipment <br /> • drill rig equipment <br /> • auto traffic <br /> fire and explosion <br /> Work procedures to protect workers from chemical and physical <br /> hazards are discussed in Section 6 . 0 . <br /> 5.1 Chemical Hazards <br /> i <br /> The primary chemical hazard is exLcosure to chemical compounds <br /> from the petroleum-affected soil and water. Of particular <br /> concern is the potential for workers to be exposed to aromatic <br /> petroleum compounds in the vicinity of the excavation. These <br /> hydrocarbons include the components of diesel, gasoline, and <br /> the common minor components of diesel and gasoline (benzene, <br /> toluene, ethylbenzene, and xylenes ) . <br /> 5. 1. 1 Chemical. Description of Diesel <br /> Diesel fuel is a gas oil fraction available in various grades <br /> as required by different engines . Composition of diesel i <br /> varies in ratios of predominantly aliphatic, olefinic, <br /> cycloparaffinic, and aromatic hydrocarbons, and additives . <br /> F <br /> Ingestion of diesel can lead to s stemic effects such as <br /> gastrointestinal irritation, vomiting, diarrhea, and in severe. <br /> cases drowsiness and central nervous system depression, <br /> progressing to coma and death. Aspiration of diesel fuel can <br /> cause hemorrhaging and pulmonary Edema, progressing to <br /> pneumonitis and renal involvement . <br /> �f <br /> 7 <br /> i <br /> i <br />
