1.3.3 Air Monitoring Requirements <br /> Section 6.0 of the HASP provides information on when air monitoring must be conducted, calibration <br /> requirements, and how to document air monitoring readings. Table 4 provides a summary of the <br /> requirements for this project site. <br /> Table 4 Air Monitoring Action Levels <br /> NOTE.EHS will add other screening instruments and action levels as per site specific requirements. <br /> MENCEIZEM <br /> INEENIMMEMEM <br /> PID(10.6eV lamp) Conduct air monitoring for <5 ppm Level D <br /> -Measures Total volatile organic compounds 5-10 ppm Upgrade to Level C.
