Where elevated exposures persist,respiratory <br /> protection will be used to protect personnel from inhalation of hydrocarbon vapors. The hydrocarbon vapors <br /> which may be encountered during the field portion of the investigation of the imported fill soils are composed <br /> of a variety of volatile refined petroleum constituents. Most of these chemicals have limited toxicity thus <br /> requiring minimal controls at the concentrations that are anticipated to be encountered.
