In what scenarios can an inspector utilize a dust wipe sample?

A dust wipe sample is a critical tool for evaluating lead exposure risks in various settings, particularly because it provides concrete evidence of lead dust levels in an environment. The use of dust wipe samples is most frequently associated with post-remediation evaluations or inspections to determine the effectiveness of lead hazard reduction efforts. If lead dust has been disturbed, for instance, during renovation or demolition, or if there has been a known lead hazard, conducting dust wipe sampling allows inspectors to assess whether the lead dust levels have been adequately controlled.

In cases of post-remediation, it is essential to ensure that lead has not accumulated again and that the environment is safe for occupants. A successful lead abatement should show that lead dust levels are below the EPA's established standards. This use of dust wipes during inspections serves as a reliable method to confirm safety and compliance with regulations aimed at protecting public health.

The other scenarios listed either limit the application of dust wipe sampling to specific situations or locations, while the primary purpose is broader, encompassing evaluations post-remediation as well as in various property types, not just residential. This adaptability makes dust wipe sampling a vital component of lead risk assessment practices.
