How does a Lead Inspector determine the presence of lead-based paint?

A Lead Inspector determines the presence of lead-based paint through a comprehensive approach called surface-by-surface investigation. This method involves testing each painted surface in the property to accurately identify areas that contain lead-based paint. The inspector typically uses specialized tools and techniques, such as X-ray fluorescence (XRF) analyzers, to assess the lead content on different surfaces.

This method is crucial because lead paint can exist on a variety of surfaces and may have different concentrations, so a thorough investigation enables the inspector to pinpoint exact locations that may pose a risk. Relying solely on visual inspection would not be sufficient, as lead-based paint may not always exhibit visible deterioration or discoloration.

In contrast, merely reviewing historical documentation might provide context about previous uses of lead-based paint but cannot confirm its current presence. Similarly, while examining soil can uncover lead contamination, it does not address the primary source of lead hazards within the home itself, which is often found in the paint on walls, windows, and other surfaces.
