F N _ <br /> The most significant risk 33sociated with petroleum fuels is <br /> exposure to aromatic compounds . skin contact will be eliminated <br /> by use of clothing, eye wear, and gloves and the inhalation <br /> hazard will be minimized using appraUllate respiratoryrotectiwe <br /> ev a3 d termined b on-site r_ monitoring. The sa£ei:y <br /> Coordinator/Project Manager will establish an exclusion zone <br /> encompassing a 50 foot radius from the work area. Access within <br /> this zone, will be limited to required personnel. . Total organic <br /> vapors will be monitored within the exclusion zone using a <br /> photolonization detector (PID) calibrated for benzene the most <br /> toxic of the aromatic hydrocarbons. Current enforceable and <br /> recommended exposure limitations for potential site contaminants <br /> are presented in Table 1.
