What three-step sequence must be applied to clean lead dust from wood surfaces?

• A. Sweep the surface to remove loose dust.
• B. Vacuum the dust, perform a wet cleaning, and vacuum again to remove remaining particles.
• C. Wipe with a dry cloth, then rinse with water.
• D. Use a bleach solution and air dry.

Answer: (B)

Cleaning lead dust safely from wood starts with a method that both captures particles and prevents them from becoming airborne. The best three-step sequence is to vacuum with a HEPA-filtered vacuum to pick up loose dust, then perform a thorough wet cleaning to lift and trap any remaining dust, and finally vacuum again to remove particles loosened during the wet cleaning. This approach minimizes dust dispersion and ensures fine lead particles are removed, which is crucial because lead dust is hazardous, especially for children. Dry sweeping or wiping can spread dust into the air and through surfaces, while simple rinsing or air drying doesn’t reliably remove settled particles.
