Exposure Monitoring
Determine the amount of lead in the air
29
Exposure Monitoring

• Permissible Exposure Limit (PEL)
• 50 micrograms per cubic meter of air averaged
  over an 8 hour day

30
Medical Program

• Blood testing
• Medical clearance for respirator use

31
Types of TrainingBasic OSHA Training

• Includes
• Contents of Cal/OHSA lead in construction
  standard
• Engineering and work practices relevant to
  employees job assignment
• Respirator use
• Purpose and description of medical program and
  medical removal protection
• No time or training method requirements
• More information in Painting Contractors Guide
  to Lead Safety

32
Types of TrainingDHS Certification

• Take 24 to 40-Hour Course Accredited by DHS
• Meet other requirements and apply to DHS
• DHS certification is available for workers and
  supervisors
• Designed to build a well-trained workforce for
  lead-related construction

33
When do Supervisors and Workers Need DHS
Certification?

• Permanent lead abatement work in residential and
  public buildings
• Lead abatement in public elementary schools or
  daycare centers
• When specifications require DHS certification
• When lead-related construction work in
  residential and public buildings is shown to
  cause exposure at or above the Permissible
  Exposure Limit (PEL) of 50 µg/m3
