PES Environmental, Inc. All personnel will be required to wear eye and ear protection, a hard hat, and steel-toed boots when working. All personnel must be aware of potential trip or fall hazards and shall exert due caution when walking in all work areas. 5.0 AIR MONITORING AND ACTION LEVELS In accordance with 29 CFR 1910.120 (h), air monitoring will be used to identify and quantify airborne levels of hazardous substances and health hazards to determine the appropriate level of employee protection needed on-site. For this project, air monitoring program will consist of a portable PID/OVA able to detect concentrations of airborne VOCs in parts per million (ppm). The PID/OVA will be calibrated, used, and maintained in accordance with the manufacturer's specifications. Air monitoring will be conducted as follows: • A minimum of twice per field mobilization to document ambient VOC levels in each active exclusion zone; • Intermittently as field work proceeds, and at a frequency commensurate with all field tasks to adequately protect workers from potential chemical exposures; • Immediately, if noticeable odors occur during field activities; • When work begins at a different location of the site; • When a different type of operation is initiated; and • When required by the SSO. PID/OVA concentrations inside the active exclusion zones are as follows: • Less than or equal to 5 ppm above background conditions: Level D; • Greater than 5 ppm above background conditions and less than 50 ppm above background: Level C (with full-face air purifying respirator [APR]); and • Greater than 50 ppm: Field activities will be immediately halted, and the location will be vacated. 148400101H002.doc 10
