Which sequence is the correct cleanup sequence after lead dust abatement or renovation?

• A. Wet clean, HEPA vacuum again, then dry sweep
• B. HEPA vacuum, dry sweep, wet clean
• C. Dry sweep, HEPA vacuum, wash with soap
• D. HEPA vacuum, wet clean, HEPA vacuum again

Answer: (D)

After a lead dust abatement or renovation, the cleanup should minimize spreading dust and capture fine particles with high-efficiency filtration. The best sequence starts by removing the bulk of dust with a HEPA-equipped vacuum, then damp-clean surfaces to physically lift and remove remaining dust, and finishes with another HEPA vacuum to catch any particles that may have been re-entrained during wet cleaning. This order reduces airborne dust best: vacuum first to reduce bulk dust, wet wipe to remove what's left without stirring it up, then a final vacuum to ensure the surface is clean and free of residual particles. Dry sweeping is avoided because it stirs up lead dust into the air, and starting with wet cleaning or skipping the final vacuum can leave particles behind.
