HEALTH AND SAFETY PLAN <br />3. HAZARD ANALYSIS <br />Hazards at the Site may include physical hazards, chemical hazards or biological hazards. Each type <br />of identified hazard is addressed in the following sections. Hazards that are the specialty of a <br />subcontractor (i.e., operation of a drill rig or excavator) are not addressed in this HASP. <br />Subcontractors are responsible for identifying potential hazards associated with their activities and <br />implementing proper controls. <br />3.1 Chemical Hazards <br />Exposure pathways of concern for chemical compounds that may be present at the Site are <br />inhalation of airborne contaminants, direct skin contact with contaminated materials, and incidental <br />ingestion of affected media. Wearing protective equipment and following decontamination <br />procedures listed in Section 9 can minimize dermal contact and incidental ingestion. To minimize <br />inhalation hazards, dust or vapor control measures will be implemented, where necessary, and action <br />levels will be observed during scheduled activities. Site-specific action levels and air monitoring <br />requirements are presented in Section 5. <br />Known or Suspected Compounds Source <br />(soil/water/sludge, etc.) <br />Known Concentration Range <br />(ppm, mg/kg, mg/I) <br />Lowest Highest <br />BTEX Groundwater/Soil unknown unknown <br />MTBE Groundwater/Soil unknown unknown <br />DRO, GRO, MRO Groundwater/Soil unknown unknown <br />Nitrates Groundwater/Soil unknown unknown <br />Chemical descriptions of chemicals of concern, including health effects and exposure limits, are <br />presented in the following paragraphs. Each chemical description includes physical and odor <br />recognition characteristics, the health effects associated with exposure, and exposure limits <br />expressed as an 8-hour time-weighted average (TWA). Provided are federal OSHA (OSHA) <br />permissible exposure limits (PELs; located in 29 CFR 1910.1000); California OSHA (Cal/OSHA) <br />PELs (located in 8 CCR 5155); and the American Conference of Governmental Industrial <br />Hygienists (ACGIH) threshold limit values (TLVs). For sites outside California, Cal/OSHA PELs <br />are included as an additional reference. <br />BENZENE <br />Benzene is a clear, volatile liquid. It is colorless, highly flammable, and toxic, with a <br />characteristic odor. It is a severe eye and moderate skin irritant. Human effects by <br />inhalation and ingestion include euphoria, changes in sleep and motor activity, nausea and <br />BROWN AND C AL DW ELL <br />3-1
