Which option lists the middle step in the standard lead dust cleaning sequence?

• A. Vacuum debris
• B. Vacuum again for remaining particles
• C. Wet clean for fine dust
• D. Dry wipe

Answer: (C)

The middle step targets the fine lead dust that remains after you’ve removed the big debris. Wet cleaning is used because damp cloths or mops capture and hold fine particles more effectively than dry methods, reducing the chance of re-aerosolizing dust. After the initial debris is removed, using a damp method lifts and traps the remaining fine dust from surfaces, which is then followed by a final cleanup pass to remove any residual dust. Dry wiping is less suitable as the middle step because it can spread dust if surfaces aren’t already damp, and a final wipe or light vacuum is typically done after the wet cleaning. Vacuuming the debris is the first step to reduce bulk, and additional vacuuming often comes after wet cleaning as a finishing pass.
