When does the EPA not require dust wipe sampling?

• A. After interior-only abatement
• B. During routine cleaning of a dwelling
• C. Never; Dust wipe sampling is always required
• D. After abatement conducted exclusively on the exterior of a dwelling

Answer: (D)

Dust wipe sampling is used as clearance testing to verify that interior surfaces meet lead-dust standards after work that disturbs lead-based paint. If abatement is performed only on the exterior of a dwelling, the interior spaces aren’t disturbed and occupants aren’t exposed to interior lead dust from that work, so the EPA does not require dust wipe sampling in that exterior-only scenario. Interior abatement, or any work that disturbs lead paint inside the home, would trigger clearance testing to confirm the space meets the applicable dust limits. Routine cleaning isn’t an abatement activity and does not trigger clearance testing.
