When cleaning the interior, how far beyond the contained work area must you clean?

• A. Two Feet
• B. One Foot
• C. Three Feet
• D. Four Feet

Answer: (A)

The idea behind this rule is to prevent lead dust from spreading beyond where you worked. After you finish inside a contained work area, you must clean not only inside that area but also at least two feet beyond its edge. This two-foot buffer captures any dust that may have settled on surfaces outside the containment, reducing the chance of cross-contamination to other parts of the interior. To do this properly, wipe and mop all surfaces inside the containment, then extend your cleaning to surfaces within that two-foot boundary—including floors, baseboards, and adjacent horizontal surfaces. Use damp wipes or a damp mop and, if required, a HEPA-equipped vacuum for the floor. After cleaning, inspect the area to ensure dust has been removed and dispose of cleaning materials properly. This two-foot requirement is the standard practice to protect occupants and workers from residual lead dust.
