1.1 The hazard analysis identifies potential hazards that pertain to specific on site activities. These activities include: Tank and Line Removal/ Excavation and Install The potential hazards to personnel working at the subject site have been identified as chemical contamination, physical hazards of working around heavy equipment, a large excavation, and heat stress ( potential for cold stress due to seasonal changes). Each potential hazard relative to potential for exposure is described below. Chemical Contamination The chemical contaminants of concern for this project are gasoline constituents [benzene, ethyl benzene, toluene, and xylene (BETX)], and chemical characteristics and exposure level information for these compounds are presented in Table C-1. The hazards associated with these chemicals are potential for fire and explosion, and potential worker exposure due to direct contact_ and/or inhalation of vapors of gasoline constituents. These potential hazards will be controlled through monitoring and the use of protective equipment as described later in this SSHP. Gasoline vapors (50 to 100 octane) are moderately to highly toxic via inhalation, which can cause central nervous system depression, pneumonitis, fatal pulmonary edema, and some addiction if exposures too the vapors are greater than 300 parts per million(ppm). Gasoline also poses fire and explosion hazards when present in sufficient concentrations and with a source of ignition. The flammable range for gasoline vapors is 1.3 to 6.0 percent by volume in air. During start-up of the system gasoline will be present in the tanks, piping, and dispensers. Table C-2 list hazards and how they will be controlled. TABLE C-2. Physical Hazards Control 1. Heavy equipment Eye contact with operator prior to approaching equipment. 2. Open excavations open excavations will be marked with tape during work hours and blocked with fencing or equipment during the off hours. 3. Uneven or slippery Care will be taken when traveling the site and the site will Walk area be kept as clean as possible.
