What happens if 1 or more clearance dust samples fail?

When any clearance dust sample fails, the space must be re-cleaned in its entirety and then re-wiped and re-sampled to verify it meets the required standard. This approach ensures that all surfaces are cleaned uniformly and that no hidden hotspots remain, reducing the risk of residual lead dust across the entire area. After re-cleaning, new clearance samples are collected to confirm the space now passes. So the best option reflects the need for comprehensive re-cleaning and a fresh round of sampling, rather than just touching up the failed spot, doing nothing, or treating the failure as final and unfixable.
