    Title: (f) Exposure Assessments and Monitoring - Initial Exposure Assessment
    Type: Text and Photo Slide
    • Assessment by a competent person before or at the initiation of an operation -- so all appropriate control systems can be applied
    • Basis:
      • Exposure monitoring is feasible
      • Observations, information, or calculations which indicate employee exposure, including any previous monitoring
      • "Negative Exposure Assessment" required to conclude that exposures are likely to be consistently below the PELs
      • Exposure above the PELs is assumed for Class I work until exposure monitoring documents otherwise, or employer makes a "negative exposure assessment"
