the potential for exposure to toxic materials through both skirt contact and inhalation. The <br /> subsurface sampling may also pose a fire and explosion hazard from gases and vapors trapped <br /> beneath the ground surface. <br /> The most significant risk associated with petroleum fuels is exposure to aromatic compounds. <br /> Sian contact will be eliminated by use of clothing, eye wear, and gloves. The inhalation hazard <br /> will be minimized using appropriate respiratory protective devices as determined by on-site air <br /> monitoring using a photoionization detector (PID) calibrated to the benzene molecule with <br /> isobutylene gas. <br /> The Safety Coordinator/Project Manager will establish an exclusion zone encompassing a <br /> conservative 50 foot radius around the work area Restricted activities inside the exclusion zone <br /> may be allowed depending on field measurements taken during the course of investigation <br /> activities Access within this zone will be limited to required personnel. <br /> Current enforceable and recommended exposure limits for potential site contaminants are <br /> presented in Table 1. <br /> QTSAF 'iY WP <br />
