31AJESTIC TECH <br /> 8 . 0 JOB HAZAPQ ANALYIS <br /> 8. 1 GENERAL <br /> The history of the site indicates that the one tank to be removed <br /> were utilized for the storage of a range of hydra artson compounds <br /> initially identified as gasoline. 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 scrapping 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 chronicallu 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 hazards 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 />
