Which sequence is correctly listed for cleaning lead dust from wood surfaces?

• A. Vacuum, sweep, dry.
• B. Dry wipe, vacuum, rinse.
• C. Wash with soap, rinse, dry.
• D. Vacuum the dust, perform a wet cleaning, and vacuum again to remove remaining particles.

Answer: (D)

Cleaning lead dust from wood is about stopping the spread of contamination while removing all particles. Start with a vacuum that has a HEPA filter to remove the loose dust. This dry removal step helps prevent dust from becoming airborne as you move to the next steps. Next, perform a damp cleaning to lift and trap the remaining particles from the wood surface. A final vacuum pass then captures any particles that were loosened or settled during the wet cleaning, ensuring the surface is as clean as possible.

This sequence matters because dry methods like sweeping or dry wiping can spread lead dust, and washing alone without first removing loose dust may leave residual particles. The three-step approach minimizes spread and maximizes removal by combining dry capture, damp cleaning, and a final vacuum.
