We will minimize the risk impacts of workers and the public by the use of personal <br /> protective equipment and barricades such as delineators, caution tape, and fencing. <br /> 14.6 Nq11111TOMEG !RJ■ <br /> A. AIR EXPOSURE MONITORING: <br /> Breathing air analysis measuring the airborne concentrations shall be performed <br /> when significant surface disturbances are involved. Monitoring shall take place with <br /> direct reading instruments and detector tubes shall be used if necessary. The Site <br /> Safety Officer will determine if and when downwind perimeter monitoring is <br /> needed. Action level for VOC's will be set at 300 ppm for level "C" respiratory <br /> equipment and light chemical clothing. <br /> B. NOISE EXPOSURE MONITORING: <br /> A potential for elevated noise exposure exists when working around heavy <br /> equipment. Hearing protection is always required under these conditions. <br /> 4L6 EMS AJ . PMOVE . MYR 86IIII)NlM®T <br /> A. SAFETY EQUIPMENT TO BE USED BY FIELD WORKERS (hi-lited): <br /> Work boots, hard hat, vinyl inner gloves, outer gloves (nitrile, leather, rubber), <br /> safetyglasses, hearing protection, tyvek suits (standard, polyethylene, saronex), <br /> fire retardant clothing. <br /> Air-purifying respirator and appropriate cartridges. <br /> Full body harness, shock absorbing lanyard, retractable life-line, emergency <br /> breathing air, orange vest. •if warranted <br /> B. LEVELS OF PROTECTION: <br /> 4 <br /> Explanation - Protective equipment selected is based on the type of contaminants, <br /> their concentrations, and the routes of entry. 300 ppm VOC's is the action level from <br /> "D" to "C". <br /> I.6 R6■K m6 m <br /> The site shall be controlled to reduce the possibility of translocation of the contaminants <br /> by personnel/equipment and dangerous levels of airborne dust, vapors, etc. This shall be <br /> accomplished by setting up physical barriers based upon the amount of space needed <br /> to perform the work and the air monitoring results. <br />
