Housekeeping

  • No Dry Sweeping
  • No Dry Brushing
  • Unless These Are Not Feasible

‒Wet Sweeping ‒HEPA-Filtered Vacuuming ‒Other Methods

slide-70
SLIDE 70

Housekeeping

  • No Compressed Air

‒ To Clean Clothing ‒To Clean Surfaces

  • Unless

‒Compressed Air is Used in Conjunction With a Ventilation System That Effectively Captures the Dust Cloud Created by the Compressed Air ‒Or, No Alternative Method is Feasible

Exposure Control Plan

slide-75
SLIDE 75

Exposure Control

Two Options

  • Table 1, That Specifies:

‒Engineering Control ‒Work Practices ‒Respirators by (APFs)

  • Alternative Exposure Control

‒Air Monitoring Determines Respirator With Engineering and Work Practices Used ‒Two Options: Performance & Scheduled

slide-76
SLIDE 76

Exposure Assessment

  • Performance Option

‒Assess the 8-Hour TWA Exposure for Each Employee on the Basis of Any Combination of Air Monitoring Data or Objective Data

  • Scheduled Monitoring Option

‒8-Hour Exposure Assessment ‒Breathing Zone ‒Representative #, Each Task, Each Area & Each Shift ‒Highest Exposure (“Worst Case”)

slide-77
SLIDE 77

Initial Exposure Assessment

  • < AL, No Further Monitoring
  • > AL but < PEL, Repeat in 6

Months

  • > PEL, Repeat Every 3 Months
slide-78
SLIDE 78

Exposure Reassessment

  • Changes Reasonably Expected to Result in

New or Additional Exposures > AL

‒Production ‒Process ‒Control Equipment ‒Personnel ‒Work Practices

  • Any Reason to Believe That New or

Additional Exposures > AL Have Occurred

slide-79
SLIDE 79

Air Sampling
