HAZARD EVALUATION <br />The following substance(s) or hazards are known or suspected to be on site. <br />SUBSTANCES INVOLVED: CONCENTRATIONS: <br />Benzene Unknown <br />Toluene Unknown <br />Ethyl-benzene Unknown <br />Total xylenes Unknown <br />MTBE Unknown <br />Solvents? Unknown <br />The primary hazards of each are identified as follows: <br />1. Solvents/Hydrocarbon fuels - Solvents and components of fuels are generally colorless <br />liquids with strong aromatic petroleum hydrocarbon-like odors. They are flammable and have <br />low solubility in water. Exposure to these materials in excess of recommended exposure <br />limits can cause mild eye, nose, and throat irritation and can produce a narcotic effect on the <br />central nervous system. Symptoms of exposure at these concentrations include headache, <br />nausea, drowsiness, dizziness, and loss of coordination. Certain components of gasoline <br />(BTEX etc.) are known or suspected carcinogens. <br />The additional potential hazards include: Slip-trip-fall hazards, noise, heavy equipment (i.e., <br />excavator/bacichoe), vibration hazards, traffic hazards, etc. <br />Advanced GeoEnvironmental, Inc.
