Which tool is recommended over a sponge for wet cleaning lead-contaminated floors?

• A. A mop used with a bucket equipped with a wringer
• B. A sponge
• C. A dry cloth
• D. A squeegee

Answer: (A)

When cleaning lead-contaminated floors, the goal is to remove contaminants while keeping dirty water and fibers contained. A mop with a bucket that has a wringer achieves this by letting you apply cleaning solution and lift it off the floor in one controlled motion, then wring out the mop to remove most of the dirty water before proceeding. This minimizes splashes and reduces the chance of spreading lead to other areas or onto your skin.

A sponge tends to trap dirty water and fibers and can release contaminants when squeezed, making containment harder and cleaning less efficient over larger areas. A dry cloth doesn’t wet-clean the surface effectively and won’t lift embedded contaminants. A squeegee can move liquid but doesn’t provide the same level of cleaning action or containment for lead-contaminated floors.

So, using a mop with a wringer bucket best balances effective wet cleaning with keeping contamination under control.
