The operations basically involve <br />accessing and emptying the tanks and pipelines, excavating and <br />removing the tanks and designated pipelines (and closing other <br />designated pipeline in place after cleaning), testing and removing <br />any contaminated soils as needed, and cleaning and strapping the <br />tanks and removed pipeline as specified. <br />As such, the operations and conditions uniQue to this Project <br />require an evaluation of severe physical and chemical hazards. <br />including specific hydrocarbon and other chemical substances, <br />equipment operations, open excavations, noise. heat stress, and <br />related hazards. <br />8.2 CHEMICAL HAZARDS <br />8.2.1 TOXIC CHEMICALS <br />Specific chemical contaminants included in the job hazard <br />analysis include benzene, toluene, ethyl benzene, xylene, <br />naptha. tetraethyl lead, trichloroethane and <br />tetrachloroethylene. These chemicals are consided potential <br />significant constituents of gasoline. Of the various <br />constiteents anticipated to be encountered during the <br />project, naptha may likely be the most common chemical <br />contaminant occuring, benzene the most chronioallu toxic, <br />and tetraethyl lead the most acutely toxic. Please refer to <br />the Chemical Hazard Fact Sheets below for additional <br />chemical characteristic and health hazard information for <br />each of the above -listed chemical hazards. <br />This Safety and Health Plan (SHP) requires that any <br />occupational exposure above the Permissible Exposure Limit <br />(PEL) or Threashold Limit Value (TLV), which ever is lower <br />(i.e., more protective), be controlled through a combination <br />of engineering controls, safe work practices, and when <br />appropriate. the use of personal protective equpiment. <br />However, significant occupational exposures to these <br />chemical hemards are not anticipated during field operations <br />for the following reasons: <br />Work activities are to be performed outdoors where <br />reasonable dilution (i.e., natural) ventilation is <br />anticipated. <br />Although some contents are expected in each tank to be <br />removed, the routine handling of large volumes of free <br />chemical is not expected. <br />
