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 /> SUBSTANCESINVOLVED CONCENTRATIONS <br /> Gasoline fuels / Diesel fuels Unknown <br /> Volatile Organic Compounds (VOCs) 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 /> • Perch loroethylene (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 />
