13 November 2007 <br />AGE -NC Project No. 07-1569 <br />Page 3 of 7 <br />The primary hazards of each are identified as follows: <br />1. Hydrocarbon fuels - Components of fuels are 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 narcotic 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 additional potential hazards include: Slip -trip -fall hazards, noise, heavy equipment (i.e., <br />excavator/backhoe), vibration hazards, traffic hazards, glass (i.e., dust /shards), etc. <br />5.0. PERSONAL PROTECTIVE EQUIPMENT <br />Based on evaluation of potential hazards, the following levels of personal protection have been <br />designated for the applicable work areas or task: <br />Specific protective equipment for each level of protection used is follows: <br />Level D: <br />hard hat <br />steel -toed boots <br />half -faced respirator (if necessary) <br />gloves <br />safety 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.
