Where elevated exposures risks are <br /> determined to exist,respiratory protection will be the primary control method to protect personnel from inhalation <br /> ' of hydrocarbon vapors. <br /> 5.2 Chemical Hazards <br /> Chemical hazards of concern(COCs)associated with the site operations that are covered by this HSP include <br /> gasoline,VOCs,fuel oxygenates, and heavy metals.Exposure to the aforementioned COCs can occur via <br /> inhalation of chemical vapors and gases,inhalation of contaminated dust and soil particles,and dermal contact <br /> with contaminated soil. The COCs at the site include the following: <br /> • BTEX <br /> • DIPE <br /> • ETBE <br /> • . Methanol <br /> ' Ethanol <br /> • Lead <br /> • MTBE <br /> • TAME <br /> • TBA <br /> • TPHd <br /> • <br /> TPI-Ig <br /> • TPHo <br /> ' In California,permissible exposure limits(PELs)for COCs are found in CCR Title 8,Section 5155.PELs refer to <br /> the maximum allowable airborne concentrations of hazardous substances and represent concentrations at which it <br /> ' is believed that nearly all the workers may be repeatedly exposed,eight hours per day,for a 40-hour workweek, <br /> without adverse effect. However,due to the wide variation in individual susceptibility,a small number of workers <br /> may experience discomfort to some or all of these chemical substances at concentrations equal to or below the <br /> P <br /> EEL.A still smaller percentage of persons may be affected more seriously from exposures at or below the PEL <br /> AmiAdmt <br /> � V&Assocmte,Anc. <br /> 1 <br />
