Hydrocarbon fuels - Components of fuels arc: colorless liquids with strong aromatic <br /> petroleum hydrocarbon-like odors. They are flammable and have low solubility in water. <br /> Exposure to these materials in excess of recommended exposure limits can cause mild eye, <br /> nose, and throat irritation and can produce a nar otic effect on the central nervous system. <br /> Symptoms of exposure at these concentrations include headache, nausea, drowsiness, <br /> dizziness, and loss of coordination. Certain components of gasoline (BTEX etc.) are known <br /> or suspected carcinogens. <br /> The following additional hazards are expected on site: ical work related to facili . Noise fallin <br /> rods fln hammer, snapped cables etc. on the backh e/excavator (if applicable). <br /> 4.0. PERSONAL PROTECTIVE EQUIPMENT <br /> Based on evaluation of potential hazards, the followin levels of personal protection have been <br /> designated for the applicable work areas or task: <br /> Exclusion Zone Drill borings A B C D Other <br /> Reduction Zone Preserve samples A B C D Other <br /> and log borings <br /> Support Zone Support functions A B C D Other <br /> Specific protective equipment for each level of protection used is follows: <br /> hard at <br /> steel toed boots <br /> Level D: half-faced respirator (if necessary) <br /> gloves <br /> safe glasses <br /> If air purifying respirators are authorized, organic vapor and dust is the appropriate canister for use <br /> with the involved substances and concentrations. No changes of the specified levels of protection <br /> shall be made without the approval of the site safety of icer and the project team leader. <br /> Advanced GeoEnvironmental,Inc. <br />
