SECTION 2 <br /> RISK ANALYSIS <br /> 2.1 CHEMICAL HAZARDS <br /> A number of products containing hazardous chemicals may be <br /> encountered at UST sites. Detailed information on the nature of <br /> these hazards may be found on the Material Safety Data Sheets <br /> (MSDS) provided by AES. These MEDS will be available on site and <br /> at the AES offices involved. <br /> The chemicals of primary concern will be those originating from <br /> leaded and unleaded gasoline, diesel fuel or waste oil. These <br /> chemicals include Petroleum Hydrocarbons as gasoline and as diesel, <br /> Benzene, Ethylbenzene, Toluene, and Xylenes, and chlorinated <br /> solvents. <br /> A GasTech Model 1314 Hydrocarbon Surveyor will be used to monitor <br /> the presence of petroleum hydrocarbon vapors present in the air. <br /> The calibration and maintenance methods are included in Appendix C. <br /> Appropriate equipment will be on site to contain a possible <br /> chemical spill. This equipment includes a chemical absorbing <br /> compound (Spill Tamer) and thick plastic sheeting. <br /> Although proper monitoring for the presence of chemicals will be <br /> routinely conducted and appropriate protective equipment used, the <br /> possibility of exposure to hazardous chemicals may exist. The <br /> signs of symptoms of exposure to hazardous chemicals includes <br /> behavioral changes, breathing difficulties, changes in skin color, <br /> coughing, dizziness, fatigue, respiratory irritation, headache, <br /> nausea, or light headedness . If these symptoms are present in any <br /> on site personnel, they will be removed from the site and if the <br /> problem persists or is severe, they will be taken to the nearest <br /> medical facility. <br /> 2.2 PHYSICAL HAZARDS <br /> 2.2.1 Explosion <br /> Gasoline vapors can be highly explosive, having a flash point of <br /> about -40 F, and are considered to be a fire hazard. <br /> 2.2.2 Heat Stress <br /> The use of protective equipment, if required, may create heat <br /> stress. Monitoring of personnel wearing personal protective <br /> clothing should commence when the ambient temperature is 70 F or <br /> above. Monitoring frequency should increase as the ambient <br /> temperature increases or as slow recovery rates are observed. <br /> 2-1 <br />
