Controlling Lead-Based Paint Hazards

1. Controlling Lead-Based Paint Hazards Chapter 5 Lead Abatement for Workers Course

2. Learning Objectives • In this Chapter you will learn about • Title X • Where is lead a hazard • Who reduces lead hazards • Lead paint abatement • Interim controls • Special cleaning techniques • O&M programs 2

3. Reducing Lead-Based Paint Hazards • Lead dust is the most common cause of lead poisoning in children. • Title X—Residential Lead-Based Paint Hazard Reduction Act of 1992—was designed to reduce lead-based paint hazards. 3

4. What is a LBP Hazard? • Any condition that causes enough exposure to lead to cause ill health • Six situations where lead is a hazard • Deteriorated LBP • LBP on friction surfaces • LBP on impact surfaces • Lead-painted surfaces that a child can chew on • Lead-contaminated dust • Lead-contaminated soil 4

10. Where is LBP Found? • Public and private buildings constructed before 1978, including • Homes • Schools • Libraries • Hospitals • Bridges and other steelstructures 10

13. Who Reduces LBP Hazards? • Certified small and large contractors • Community organizations and tenant associations • Public employees • Homeowners • Contractors, supervisors, and workers 8

14. How Will Lead Hazards Be Reduced? • Title X provides a detailed plan for reducing lead hazards • Standards developed by EPA, HUD, and OSHA • Public education • Pre-renovation notification • Notification and Disclosure Rule • Certification requirements 14

15. Title X: Two-Step Plan for Reducing Lead Hazards • Evaluate lead hazards • Which homes take priority? • Who might get poisoned? • How can lead hazards be minimized? • Reduce lead hazards • Abatement vs. interim controls 15

16. Abatement ... … is a set of actions that permanently eliminate lead-based paint hazards • Replacement • Removal • Enclosure and encapsulation • Cleanup of lead dust • Removal or permanent covering of lead-contaminated soil • Site preparation and cleanup • Waste disposal • Final inspections and clearance testing 16

17. Interim Controls ... . . . are actions that reduce a lead hazard temporarily • Education programs • Special cleaning methods • Repairs, repainting, and maintenance 17

19. Lead Cleaner Interim Control Plan for a House • These actions can reduce leadexposure in a home • Do a special cleaning • Do small repairs to windows to reduce lead dust • Wet scrape edges and loose paint • Wash entire house with cleaning solution again • Have clearance dust wipe testing done by a certified inspector or risk assessor • Repaint wet-scraped surfaces with non-lead-based paint 19

20. In-Place Management • Needed whenever interim controls are used and lead-based painted surfaces remain • Can help prevent lead poisoning LBP Management Kit 20

21. In-place management should include: Education Training Written program Lead program manager Ongoing monitoring Recordkeeping

22. Holistic Approach to Lead Hazard Control • Lead work should always be part of the maintenance approach • Long term maintenance issues should be considered 22

23. Special Cleaning Methods • Should be used when working with lead-based painted surfaces • Can be used alone to control lead dust • Must be used with abatement methods • Should be used with interim control methods • Two methods work well • HEPA vacuums • All-purpose cleaners or lead-specific cleaners 23

24. Use of HEPA Vacuums • Lightly mist area with water to minimize dust levels • Move slowly • Vacuum all surfaces • Use special attachments • Maintain the vacuum in good condition 24

27. Lead Cleaner Wet Cleaning • Some detergents contain TSP (trisodium phosphate) • Other special cleaners 27

30. The Four-Step System • Step 1: Spray or pour on the cleaning solution • Step 2: Wash surfaces with cleaning solution • Step 3: Squeeze out dirty rag or mop head • Step 4: Rinse the surfaces Remember to repeat the HEPA vacuum process! 30
