ON-SITE CONTROL <br />The Site Safety Officer will coordinate site access control and security. An exclusion <br />zone will be established approximately 10 feet around excavation. No unauthorized <br />person shall be allowed within this exclusion area. <br />4.0. HAZARD EVALUATION <br />The following substance(s) or hazards are known at the following concentrations: <br />SUBSTANCES INVOLVED <br />CONCENTRATIONS <br />Gasoline fuels / Diesel fuels <br />Unknown <br />Volatile Organic Compounds (VOCs) <br />Unknown <br />Metals or other chemical elements <br />Unknown <br />The primary hazards of each are identified as follows: <br />• Hydrocarbon fuels - Components of fuels are colorless liquids with strong <br />aromatic petroleum hydrocarbon -like odors. They are flammable and have low <br />solubility in water. Exposure to these materials in excess of recommended <br />exposure limits can cause mild eye, nose, and throat irritation and can produce a <br />narcotic effect on the central nervous system. Symptoms of exposure at these <br />concentrations include headache, nausea, drowsiness, dizziness, and loss of <br />coordination. Certain components of gasoline (BTE&X etc.) are known or <br />suspected carcinogens. <br />• Perchloroethylene (PCE) - Colorless liquid used for dry cleaning fabrics. PCE is <br />known to have a sweet odor detectable at a concentration of 1 part per million <br />(ppm). PCE is classified by the International Agency for Research on Cancer as <br />a Group 2A Carcinogen, meaning that it is probably carcinogenic to humans. <br />PCE is a central nervous system depressant and can enter the body through <br />respiratory or dermal exposure. Exposure to Concentrations of 200 ppm or more <br />have been associated with dizziness, confusion, headache, nausea, and irritation <br />of the eyes and mucous tissue. Exposure to extremely high levels of PCE may <br />lead to unconsciousness and, in extreme cases, death from respiratory <br />depression. Nausea and vomiting may follow from inhalation of large amounts of <br />PCE. <br />Symptoms of exposure to skin can include redness, itching, blistering, and pain. <br />Prolonged exposure can result in the removal of natural protective oils from skin <br />resulting in irritation, dryness, cracking and dermatitis. Likewise, extended dermal <br />
