Action limits identified are based on <br /> coifs were derived t°rorn tris Z�ccupatio a/ a ety and"Realth Guidance <br /> anual for Hazardous Waste Site Activities). <br /> ......................................................................................................................................................................................................................................................................................................... <br /> Air sample collection and analysis are used to determine the identity and quantity of <br /> materials to which workers are exposed throughout the work shift. Consistent with <br /> HAZWOPER, personal air samples are collected in the breathing zones of employees <br /> expected to have the highest exposure during the task or in the facility location being <br /> evaluated. If exposures for these employees exceed the exposure limits identified in <br /> Table 7-1 b, additional samples are collected in the breathing zones of all employees <br /> associated with the task or the facility location evaluated. Full-shift and short-term <br /> samples are collected, providing quantitative results that can be compared to OSHA <br /> Permissible Exposure Limits and other published exposure limits. Frequency and <br /> duration of sample collection are also consistent with the requirements in OSHA's <br /> substance-specific standards, including <br /> Table 7-1 b summarizes the type and frequency of air sample collection and analysis <br /> during this project. Table 7-1 b also identifies exposure limits for data interpretation and <br /> the appropriate actions when airborne concentrations exceed these values. <br /> Chapter 7 - 4 <br />
