0 0 <br /> 4.5 AIR MONITORING PROGRAM <br /> The likelihood of encountering hazardous levels of hydrocarbons during the performance of the <br /> work outlined in the Workplan is considered to be low due to the low concentrations found in <br /> earlier sampling. However,the air in the employees' breathing zone will be monitored periodically <br /> for the presence of hydrocarbons with a PID5. If the PID measures hydrocarbon levels above 100 <br /> ppm, employees will immediately don their half face respirators with organic vapor cartridges <br /> (modified Level C). <br /> Respirators will continue to be worn until the PID indicates total petroleum below 50 ppm. <br /> If dusty conditions develop in the contaminated area,the ground will be misted with water to <br /> prevent inhalation, skin contact, or ingestion of dust which may be contaminated with lead, <br /> chromium,herbicides, or pesticides. <br /> 5.0 DECONTAMINATION <br /> All sampling equipment and personnel will be appropriately decontaminated between each <br /> sampling event and before leaving the site, in the decontamination area. Sampling tools, faces, <br /> hands, and respirators will be washed first with clear water and Alconox/Liquinox,then rinsed with <br /> water. Disposable items and contaminated decontamination rinseate will be transferred to 55-gallon <br /> drums and stored on site, pending analytic results. These items and rinseate will then be disposed of <br /> in the appropriate manner. <br /> 'PID is a Photo Ionization Detector used to detect non-specific hydrocarbon vapor levels. <br /> 03009-10017-37020 5 WINZLER&KELLY <br /> August 2011 <br />
