Site Health and Safety Plan <br />19133 East Liberty Road, Clements, California <br />August 16, 2022 <br />Page 6 <br /> <br />Sharp Environmental Technologies, Inc. <br />5. SITE HAZARD ANALYSIS <br />Site operations designated in this SHSP may result in exposure to the following general types of <br />chemical, biological, or physical hazards. <br />5.1 Site Hazard Overview <br />A hazard analysis of the work activities that involves potential exposure to chemical contaminants or <br />physical hazards is provided in the following table. The hazard analysis provides a general ranking of <br />high, moderate or low based on anticipated site conditions. <br />Potential Hazard Task 1 <br />Soil, Soil <br />Vapor and <br />Water <br />Sampling <br />Task 2 <br />Air <br />Monitoring <br />Task 3 <br />Excavation <br />Task 4 <br />Transportation <br />Inhalation of vapors Moderate Moderate Moderate Moderate <br />Skin and Eye contact Moderate Moderate Moderate Moderate <br />Ingestion Low Low Low Low <br />Inhalation of Dust Moderate Moderate High High <br />Heat Stress Moderate Moderate Moderate Moderate <br />Heavy Equipment Moderate Low High High <br />Traffic Moderate Moderate High High <br />Noise Moderate Low High High <br />Trips/Falls Moderate Low High High <br />Utilities Low Low Moderate Moderate <br />Electrical Low Low Low Low <br />Illumination Low Low Low Low <br />Flammable Hazards Low Low Low Low <br />Biological Hazards Low Low Low Low <br />Other Low Low Low Low <br /> <br />Exposure to elevated levels of hydrocarbon vapors presents potential health risks that need to be <br />properly understood and controlled. These vapors constitute a health hazard when inhaled, and they <br />present a fire or explosion risk when they accumulate in an explosive mixture with oxygen. Where <br />elevated exposures risks are determined to exist, respiratory protection will be the primary control <br />method to protect personnel from inhalation of hydrocarbon vapors. <br />5.2 Chemical Hazards <br />Chemical hazards of concern (COCs) associated with the site operations that are covered by this SHSP <br />include VOCs. Exposure to the aforementioned COCs can occur via inhalation of chemical vapors and <br />gases, inhalation of contaminated dust and soil particles and dermal contact with contaminated soil.
